[0061] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0062] In this application, relational terms such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0063] In order to better understand this application, the technical names involved in this application are explained below:

[0064] Tomcat middleware: Tomcat server is a free and open source lightweight Web application server. It can process HTML page related requests, but its main function is Servlet and JSP container, which is used for the dynamic request processing in Web services.

[0065] Instance: A process or runtime that measures the entity of a service program.

[0066] Configuration information: A collection of key parameters or configurations that affect the process or runtime, used to define and describe the program's running status and behavior.

[0067] See also Figure 1, shows a flow chart of a data collection method provided in an embodiment of the present application, the data collection method specifically comprises the following steps:

[0068] S101: Send corresponding scripts to all hosts, so as to filter out at least one Tomcat process from various processes maintained on the hosts through the scripts.

[0069] In the process of performing step S101, a script for analyzing the characteristics of the Tomcat process can be pre-set to find the Tomcat process using the script; specifically, the corresponding script is sent to all hosts to call the script to determine the Tomcat handle from the various handles maintained on each host, and the Tomcat handle is used to filter out at least one Tomcat process from the various processes maintained on the host, and finally at least one Tomcat process can be further filtered out from various other processes. Among them, the other processes are processes other than the Tomcat process and the preset process filtered out using the Tomcat handle among the various processes maintained on the host, that is, processes other than the Tomcat process and the preset process to which the Tomcat handle belongs.

[0070] Optionally, the process of sending corresponding scripts to all hosts and filtering out at least one Tomcat process from various processes on the host through the script can be specifically as follows: for each host, sending the corresponding script to the host; obtaining the handle table maintained on the host through the script; wherein the handle table includes multiple handles maintained on the host; querying the handles with Tomcat characteristics from each handle through the script, and determining the handles with Tomcat characteristics as Tomcat handles; obtaining the process table maintained on the host through the script, and identifying the Tomcat process to which the Tomcat handle belongs from each process in the process table; filtering out the Tomcat process with Tomcat core files from various other processes through the script; wherein other processes are processes other than the Tomcat process to which the Tomcat handle belongs and the preset process in each process.

[0071] In the embodiment of the present application, for independently deployed Tomcat or Spring Boot applications packaged in WAR (Web Application Archive), a Tomcat handle containing catalina.jar or tomcat-embed-core-xxx.jar can be found during runtime. The Tomcat handle contains the core code of the Tomcat container operation, that is, the core code such as catalina.jar or tomcat-embed-core-xxx.jar that must exist when the Tomcat container is started. Therefore, the core code such as catalina.jar or tomcat-embed-core-xxx.jar can be set as a Tomcat feature, so the Tomcat handle can be identified from each handle maintained on the host through the Tomcat feature, and the Tomcat process to which the Tomcat handle belongs can be identified from each process maintained on the host, so that the identified Tomcat process can be used to check the non-encapsulated Tomcat instance later, and the process information such as the process number of each Tomcat process can also be recorded. Among them, the tomcat-embed-core-xxx.jar here represents the core code of the Tomcat container operation.

[0072] It should be noted that handles refer to objects managed by the operating system deployed on the host. In Linux, all objects are files, so they can also be called open files. The running of a process will include various objects, which constitute the necessary data set when the process is running. In the Linux operating system, all handles can be listed through the lsof command, that is, all handles maintained on the host can be obtained by calling the corresponding script according to the lsof command.

[0073] It should also be noted that the preset process can be a special java process in the form of jar. The applicant has found through research that, since the application service encapsulated in the form of jar is also applicable to the Tomcat container, the handle seen in the operating system is usually a single file, not like the Tomcat process to which the Tomcat handle belongs, there will be multiple files, and these files often have no obvious identification. Therefore, each file under each process can only be unpacked and parsed to find the Tomcat core file tomcat-embed-core-xxx.jar, and the process with the Tomcat core file is determined as the Tomcat process.

[0074] Furthermore, in an embodiment of the present application, after identifying at least one Tomcat process to which the Tomcat handle belongs from each process, the determined Tomcat process and the preset process can be excluded from each process to obtain multiple other processes; for each other process, all files under the other process are obtained, and each file under the other process is unpacked and parsed in turn to determine whether there is a Tomcat core file in each file under the other process; if there is a Tomcat core file in each file under the other process, the other process is determined to be a Tomcat process; otherwise, it is determined that the other process is not a Tomcat process.

[0075] In actual application, the preset process is a special Java process in the form of jar, and the core code such as catalina.jar or tomcat-embed-core-xxx.jar is set as the Tonmcat feature, and the second Tomcat feature is tomcat-embed-core-xxx.jar; the tomcat-embed-core-xxx.jar file is set as the Tomcat core file; see Figure 2 , by sending a script to the host, calling the script to obtain all handles maintained on the host according to the lsof command, and saving all handles to a temporary file; judging whether there is a Tomcat handle containing Tomcat features in each handle; if so, identifying the Tomcat process to which the Tomcat handle belongs from each process maintained on the host, and recording the process information of the Tomcat process; excluding the determined Tomcat process and a special java process in the form of a jar from each process, and obtaining multiple other processes, if not, determining the processes other than the special java process in the form of a jar as other processes; screening out all jar files under other processes, and unpacking and parsing each jar file under the other process in turn, to judge whether there is a Tmocat core file under the other process, if so, it can be determined that the other process has started a Tomcat container, that is, it can be determined that the other process is a Tomcat process, and the process information of the Tomcat process is recorded; otherwise, it is determined that the other process is not a Tomcat process.

[0076] It should be noted that since Tomact instances exist in various forms and are not easy to start, the Tomcat process is identified through the above method, and then the corresponding Tomcat instance is determined based on the identified Tomcat process. This is not only applicable to various scenarios, but also can accurately identify the Tomcat process, thereby accurately obtaining the corresponding Tomcat instance.

[0077] S102: For each Tomcat process, the Tomcat instance corresponding to the Tomcat process is stored in a database, and the host to which the Tomcat process corresponding to the Tomcat instance belongs is marked.

[0078] In the process of specifically executing step S102, for each host, after scanning at least one Tomcat process from each process maintained on the host, for each Tomcat process, a Tomcat instance corresponding to the Tomcat process can be further obtained; the Tomcat instance is stored in the database, and at the same time, the host to which the Tomcat process belongs can be marked, that is, the host to which the Tomcat process belongs is marked as the target host.

[0079] S103: Determine the Tomcat instance to be collected from all Tomcat instances under the target host, and determine whether the Tomcat instance to be collected meets the configuration information collection condition. If the Tomcat instance to be collected meets the configuration information collection condition, execute step S104.

[0080] In the embodiment of the present application, in order to optimize the business banking of the bank, the specific application process started by Tomcat can be excluded, that is, after scanning out the various Tomcat instances marked under each host, and marking the host to which the Tomcat process corresponding to the Tomcat instance belongs as the target host, the various Tomcat instances under each target host with the mark can be further scanned, and the Tomcat instances whose Tomcat processes are specific applications started by Tomcat are excluded from the scanned Tomcat instances, that is, the configuration information is not collected for the Tomcat instances whose Tomcat processes are specific applications started by Tomcat. It can be seen that the corresponding configuration information collection conditions are set, and the configuration information is collected for the Tomcat instance when the Tomcat instance meets the configuration information collection conditions, otherwise, the configuration information is not collected for the Tomcat instance. Among them, the configuration information collection conditions indicate that the Tomcat process corresponding to the Tomcat instance is not a Tomcat instance of a specific application started by Tomcat.

[0081] Optionally, the process of determining the Tomcat instance to be collected from all Tomcat instances under the target host and judging whether the Tomcat instance to be collected meets the configuration information collection condition can be specifically as follows: determining the Tomcat instance to be collected from all Tomcat instances under the target host; judging whether the Tomcat process corresponding to the Tomcat instance to be collected is a specific application process started by Tomcat; if the Tomcat process corresponding to the Tomcat instance to be collected is a specific application process started by Tomcat, it is determined that the Tomcat instance to be collected does not meet the configuration information collection condition, and the Tomcat instance to be collected can be excluded from each Tomcat instance of the target host, and the Tomcat instance to be collected can be re-determined from all Tomcat instances under the host until the location of the Tomcat instance to be collected does not exist in each Tomcat instance under the target host; if the Tomcat process corresponding to the Tomcat instance to be collected is not a specific application process started by Tomcat, it is determined that the Tomcat instance to be collected meets the configuration information collection condition.

[0082] S104: Initialize the structure of the Tomcat instance to be collected to obtain the data structure of the Tomcat instance to be collected.

[0083] In the process of executing step S104, since the database has certain data structure storage requirements for the stored data, when it is determined that the Tomcat instance to be collected meets the configuration information collection, the structure of the Tocmat instance to be collected can be initialized according to the data structure pre-set in the database to obtain the data structure of the Tomcat instance to be collected, so that after the corresponding configuration information is collected, the collected configuration information can be filled into the data structure of the Tomcat instance to be collected to obtain a Tomcat configuration information data model that meets the storage requirements of the database.

[0084] S105: Collecting configuration information of the Tomcat instance to be collected from the target host to which the Tomcat instance to be collected belongs, and generating a Tomcat configuration information data model according to the configuration information and data structure of the Tomcat instance to be collected.

[0085] In the process of specifically executing step S105, a pre-configured automated tool system can be used to obtain the installation directory of the Tomcat instance to be collected, the location and version of the java main program, the application service port information, the process startup user and the complete startup command line, and the version number of the Tomcat instance to be collected from the target host to which the Tomcat instance to be collected belongs. Finally, according to the basic information, installation directory, the location and version of the java main program, the jmx port, the application service port information, the process startup user and the complete startup command line, and the version number of the Tomcat instance to be collected, the configuration information of the Tomcat instance to be collected is generated, and the collected configuration information of the Tomcat instance is filled into the corresponding data structure to obtain the Tomcat configuration information data model of the Tomcat instance to be collected.

[0086] It should be noted that the corresponding configuration information is collected through a pre-configured automated tool system without the need to install an additional client agent on the target host. Not only does the collection process have a low resource usage rate, but it is also non-intrusive and has no impact on other application software and programs on the target host, thereby improving the accuracy and speed of configuration information collection.

[0087] Optionally, the process of collecting the configuration information of the Tomcat instance to be collected from the target host to which the Tomcat instance to be collected belongs may specifically be as follows: according to the Tomcat handle of the Tomcat process belonging to the Tomcat instance to be collected, obtaining the installation directory of the Tomcat instance to be collected from the target host to which the Tomcat instance to be collected belongs; according to a preset startup command line, obtaining the location and version of the corresponding java main program from the target host to which the Tomcat instance to be collected belongs; according to a preset command line, obtaining the corresponding jmx port from the target host to which the Tomcat instance to be collected belongs; according to a preset command line, obtaining the corresponding jmx port from the target host to which the Tomcat instance to be collected belongs; according to a preset command line, obtaining the corresponding jmx port from the target host to which the Tomcat instance to be collected belongs. According to the application service port collection method set, the corresponding application service port information is collected from the target host to which the Tomcat instance to be collected belongs; the process startup user and the complete startup command line are obtained from the target host to which the Tomcat instance to be collected belongs; the version number of the Tomcat instance to be collected is obtained from the target host to which the Tomcat instance to be collected belongs; the configuration information of the Tomcat instance to be collected is generated according to the basic information of the Tomcat instance to be collected, the installation directory, the location and version of the java main program, the jmx port, the application service port information, the process startup user and the complete startup command line and the version number of the Tomcat instance to be collected.

[0088] In an embodiment of the present application, the pre-set application service port collection method may include a pre-set command line, application log, the number of sockets established in the monitoring, etc., which is not limited in the embodiment of the present application.

[0089] It should also be noted that, due to the different configuration methods of service ports in various situations, it is impossible to accurately find each service port, resulting in collection omissions; therefore, this application sets a unified application service port collection method for each service port, so as to accurately find each application service port from the host according to the application service port collection method. Among them, the application service port information includes each application service port, and each application service port includes the server.port keyword, the port keyword in the Connector, the -nio- keyword, the active port with the maximum number of connections, etc., which are not limited in this embodiment of the application.

[0090] Specifically, you can find the server.port keyword by parsing the corresponding command line, that is, find the server.port keyword from the process startup command line; find the port keyword in the Connector from the configuration file . / conf / server.xml; find the -nio- keyword by scanning the log, that is, find the -nio- keyword from the server startup log or operation log; scan the Socket connection to determine the active port with the largest number of connections, that is, find the active port with the largest number of connections through the number of connections of the process listening port (the number of connections of the listened ports can be merged and sorted, and the port with the most connections can be confirmed as the possible listening port).

[0091] In some embodiments, since the collected application service ports may be empty or inconsistent during the application service port collection process, it can be determined whether each collected application service port meets the port election rules. If so, each application service port can be recorded; if not, each application service port can be set to empty.

[0092] In some embodiments, it can be determined whether the Tomcat instance to be collected is an independent instance or an embedded instance based on the condition that the Tomcat handle of the Tomcat process of the Tomcat instance to be collected contains the tomcat keyword but does not contain tomcat-embed-core; if it is an independent instance, the Tomcat instance to be collected is marked and the corresponding special information acquisition method is executed to obtain the version number of the Tomcat instance to be collected.

[0093] In actual application, see Figure 3, determine the Tomcat instance to be collected from all Tomcat instances under the target host; initialize the structure of the Tocmat instance to be collected according to the data structure pre-set in the database to obtain the data structure of the Tomcat instance to be collected; determine whether the Tomcat process corresponding to the Tomcat instance to be collected is a specific application process started by Tomcat; if so, the Tomcat instance to be collected can be excluded, and a new Tomcat to be collected can be re-determined from the various Tomcat instances under the target host; if not, the Tomcat handle of the Tomcat process of the Tomcat instance to be collected can be used to obtain the installation directory (Tomcat installation path and software version) of the Tomcat instance to be collected from the target host; according to the pre-set startup command line, obtain the corresponding java main program from the target host. The location and version (Java installation path and software version) of the target host are obtained through the preset command line. The corresponding jmx port is obtained from the target host. According to the preset application service port collection method, each application service port is collected from the target host, and it is determined whether each collected application service port meets the port election rule. If it meets the rule, each application service port (Tomcat service port) is recorded. If it does not meet the rule, each application service port is set to empty. The process startup user and the complete startup command line (Tomcat startup user and Tomcat startup command line) are obtained from the target host. The version number of the Tomcat instance to be collected (whether it is an embedded instance) is obtained from the target host to complete the collection of the configuration information of the Tomcat instance to be collected and obtain the corresponding configuration information. According to the configuration information and data structure of the Tomcat instance to be collected, a Tomcat configuration information data model is generated, such as Figure 4 As shown; the Tomcat configuration information data model of the Tomcat instance to be collected is stored in the database; it is determined whether there are any Tomcat instances to be collected among all the Tomcat instances under the target host; if so, it is determined again whether there are any Tomcat instances to be collected among all the Tomcat instances under the target host; otherwise, the corresponding configuration information collection process is terminated.

[0094] It should be noted that from Figure 4 It can be seen that the basic information of the Tomcat instance to be collected may include: instance retrieval name, host name of the target host, IP address of the target host, whether it is valid, etc.

[0095] It should also be noted that, as can be seen from the above content, this application uses a combination of multiple configuration information collection methods. When multiple different parameter values ​​(multiple application service ports) are collected, port election rules are used for automatic judgment, which can ensure a high information recognition accuracy rate in extreme cases.

[0096] S106: storing the Tomcat configuration information data model of the Tomcat instance to be collected in the database.

[0097] In the process of specifically executing step S106, after obtaining the Tomcat configuration information data model of the Tomcat instance to be collected, the Tomcat configuration information data model of the Tomcat instance to be collected can be directly stored in the database, and at the same time, the Tomcat instance to be collected can be excluded from the various Tomcat instances in the corresponding host, that is, the Tomcat instance to be collected is marked as collected; determine whether there are Tomcat instances to be collected in the various Tomcat instances of the target host; if so, return to execute to determine the Tomcat instance to be collected from all Tomcat instances under the target host, that is, return to execute step S103 until there are no Tomcat instances to be collected in the various Tomcat instances under the target host.

[0098] The present application provides a Tomcat instance and a configuration information collection method thereof.
