[0060] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0061] The alarm method provided in the embodiment of the present application can be applied in the application environment shown in FIG1. ​​Among them, the server 102 can be a master server in a distributed storage cluster, and the server 104 can be a slave server in the distributed storage cluster. The server 102 can be connected to the server 104 in communication. When the master server 102 receives a data file to be processed, the received data file can be stored in the master server 102 and the slave server 104 in a dispersed manner. When the master server 102 fails, a slave server will be selected from other slave servers 104 as the master server. The failure of the slave server will not affect other servers in the distributed storage cluster.

[0062] In an exemplary embodiment, as shown in FIG2 , an alarm method is provided, which is described by taking the method applied to the main server in FIG1 as an example, and includes the following steps:

[0063] S201, obtaining time synchronization information of a master server in a distributed storage cluster; the time synchronization information includes external time synchronization information and internal time synchronization information of the master server;

[0064] The external time synchronization information of the master server refers to the time synchronization information between the master server and servers outside the distributed storage cluster, and the internal time synchronization information of the master server refers to the time synchronization information of the master server itself.

[0065] Optionally, in this embodiment, the main server can determine the external time synchronization information of the main server by running a script to check whether the time synchronization between the main server and the external server is normal. In addition, the main server can determine the internal time synchronization information of the main server by checking whether its own time synchronization service is normal.

[0066] S202: Determine a first time synchronization state of the master server according to the external time synchronization information and the internal time synchronization information.

[0067] In this embodiment, the main server can determine the time synchronization status between the main server and the external server based on the above-mentioned external time synchronization information, and determine the time synchronization status of the main server based on the above-mentioned internal time synchronization information. If the time synchronization status between the main server and the external server is normal, and the time synchronization status of the main server itself is also normal, the main server can determine that the first time synchronization status of the main server is a normal state; if the time synchronization status between the main server and the external server is abnormal, or the time synchronization status of the main server itself is abnormal, the main server can determine that the first time synchronization status of the main server is an abnormal state.

[0068] S203, generating alarm information according to the first time synchronization state and the second time synchronization state of each slave server; the alarm information is used to indicate whether there is a time synchronization anomaly in the distributed storage cluster.

[0069] In this embodiment, the master server can determine the second time synchronization status of each slave server based on the information sent by each slave server, and then determine whether there is a time synchronization anomaly in the distributed storage cluster based on the first time synchronization status of the master server and the second time synchronization status of each slave server. When it is determined that there is a time synchronization anomaly in the distributed storage cluster, an alarm message is generated. The alarm message prompts that there is a time synchronization anomaly in the distributed cluster, and the maintenance personnel are notified in time to handle the time synchronization anomaly in the distributed storage cluster.

[0070] In the above alarm method, the master server in the distributed storage cluster obtains time synchronization information including external time synchronization information and internal time synchronization information of the master server, so that the master server can accurately determine the first time synchronization status of the master server itself according to the acquired external time synchronization information and internal time synchronization information, so that according to the first time synchronization status of the master server and the second time synchronization status of each slave server, an alarm information characterizing the existence of time synchronization anomalies in the distributed storage cluster can be generated. Since the alarm information is generated according to the first time synchronization status of the master server and the second time synchronization status of each slave server, both the time synchronization status of the master service itself and the time synchronization status of each slave server are taken into account, so that the master server can timely and accurately discover the time synchronization anomalies of the distributed storage cluster, improve the high availability of the distributed storage cluster, and reduce the impact on the business.

[0071] In this embodiment, the detailed process of generating alarm information by the master server according to its own first time synchronization state and the second time synchronization state of each slave server is explained. In an exemplary embodiment, as shown in FIG3 , the above S203 includes:

[0072] S301, generating alarm information when the first time synchronization state is an abnormal state.

[0073] In this embodiment, when the master server determines that the first time synchronization state is an abnormal state, it indicates that the external time synchronization information between the master server and the external server is abnormal, or the time synchronization information inside the master server is abnormal, and the master server can generate an alarm message to prompt the operation and maintenance personnel that there is a time synchronization abnormality in the distributed storage cluster. It can be understood that when the master server determines that the first time synchronization state is a normal state, it indicates that the external time synchronization information between the master server and the external server is normal, and the time synchronization information inside the master server is normal, and there is no time synchronization abnormality in the distributed storage cluster.

[0074] S302: Generate alarm information when the first time synchronization state is a normal state and any second time synchronization state is an abnormal state.

[0075] In this embodiment, when the first time synchronization status of the master server is normal, the master server can determine whether the second time synchronization status of each slave server is abnormal. If the second time synchronization status of any slave server is abnormal, it means that there is a slave server with time synchronization abnormality in the distributed storage cluster. The master server can generate an alarm message to prompt the operation and maintenance personnel that there is a time synchronization abnormality in the distributed storage cluster, so that the operation and maintenance personnel can further determine the server with time synchronization abnormality in the distributed storage cluster.

[0076] Furthermore, as an optional implementation, the master server may also display the slave server nodes whose time synchronization status is determined to be abnormal. On this basis, as another optional implementation, if the number of slave servers whose time synchronization status is determined to be abnormal by the master server exceeds a preset number threshold, the master server may display the slave server nodes before the number threshold. For example, if the master server determines that the number of slave servers whose time synchronization status is abnormal exceeds 10, the master server may display the first 10 slave server nodes determined.

[0077] In this embodiment, the master server generates an alarm message when its own first time synchronization state is an abnormal state, and generates an alarm message when its own first time synchronization state is a normal state and the second time synchronization state of any slave server is an abnormal state. This can fully consider the time synchronization function of each server in the distributed storage cluster, ensure timely and accurate detection of whether there is a time synchronization anomaly in the distributed cluster, improve the high availability of the distributed storage cluster, and reduce the impact on the business.

[0078] In this embodiment, the process of determining the second time synchronization state of the slave server is explained. In an exemplary embodiment, as shown in FIG4 , the method further includes:

[0079] S401, for each slave server, obtaining node information reported by the slave server and a time interval for reporting the node information.

[0080] First, it should be noted that, for each slave server, the method for determining the second time synchronization state of the slave server is the same, and this embodiment will be explained by taking a slave server as an example. In this embodiment, for each slave server, the master server can determine the time interval for reporting the node information from the slave server by the time when the slave server reports the node information, and obtain the node information reported by the slave server and the time interval for reporting the node information. Exemplarily, the time interval in this embodiment can be one minute, or two minutes, etc., and this embodiment does not limit the specific value of the time interval.

[0081] S402: Determine a second time synchronization state of the slave server according to the time interval and the node information.

[0082] Optionally, in this embodiment, the master server may determine the second time synchronization state of the slave server based on whether the time interval for reporting node information from the slave server is greater than a preset time interval, and the content of the node information reported by the slave server. Further, as an optional implementation, the master server may determine the second time synchronization state of the slave server based on the time interval for reporting node information from the slave server or any one of the node information reported by the slave server. For example, if the master server determines that the time interval for reporting node information from the slave server is greater than a preset time interval, the master server may determine that the second time synchronization state of the slave server is an abnormal state; or, if the master server determines that there is a time synchronization anomaly in the slave server based on the node information reported by the slave server, the master server may also determine that the second time synchronization state of the slave server is an abnormal state.

[0083] In this embodiment, the master server can accurately determine the second time synchronization status of each slave server by obtaining the node information reported by the slave server and the time interval for reporting the node information, based on the time interval for reporting the node information from the slave server and the reported node information, thereby ensuring the accuracy of determining the second time synchronization status of the slave server, thereby enabling the master server to accurately determine whether there is a time synchronization anomaly in the distributed storage cluster.

[0084] In this embodiment, the detailed process of determining the second time synchronization state of the slave server according to the time interval of reporting the node information from the slave server and the node information reported from the slave server is explained. In an exemplary embodiment, as shown in FIG5 , the above S402 includes:

[0085] S501: When the time interval is greater than or equal to a preset time period, determine that the second time synchronization state is an abnormal state.

[0086] In this embodiment, when the master server determines that the time interval for reporting node information from the slave server is greater than or equal to a preset time period, it can be considered that not only is there an abnormality in time synchronization on the slave server, but there may be an abnormality in the entire slave server. At this time, the master server can determine the second time synchronization state of the slave server as an abnormal state.

[0087] S502: When the time interval is less than a preset time period, determine a second time synchronization state according to the node information.

[0088] In this embodiment, when the master server determines that the time interval for reporting node information from the slave server is less than a preset time period, the master server can determine that the slave server can report the node information on time, and further, the master server can determine the second time synchronization state of the slave server based on the node information reported by the slave server. Optionally, as an optional implementation, the master server can parse the node information reported by the slave server, parse out the time synchronization information of the slave server from the reported node information, and determine the second time synchronization state of the slave server based on the parsed time synchronization information.

[0089] In this embodiment, when the time interval for the slave server to report node information is greater than or equal to the preset time period, the master server can promptly determine the second time synchronization status of the slave server as an abnormal state. When the time interval for the slave server to report node information is less than the preset time period, the master server can further accurately determine the second time synchronization status of the slave server based on the node information reported by the slave server, thereby ensuring the accuracy of the determined second time synchronization status of the slave server, so that the master server can promptly determine whether to generate an alarm message based on the second time synchronization status of each slave server, thereby enabling the operation and maintenance personnel to promptly discover whether there is a time synchronization abnormality in the distributed storage cluster.

[0090] In this embodiment, the process of determining the second time synchronization state of the slave server according to the node information reported by the slave server by the master server is described in detail. In an exemplary embodiment, as shown in FIG6 , the above S502 includes:

[0091] S601, obtaining the execution result of the slave server time synchronization, the current time and the time jump information from the node information; the time jump information is used to indicate whether the number of time jumps occurring from the slave server within a preset time period is greater than a preset number threshold.

[0092] In this embodiment, the master server can parse the node information reported by the slave server, and parse the execution result of the slave server time synchronization, the current time of the slave service, and the time jump information of the slave server from the above node information. Among them, the time jump information of the slave server is used to indicate whether the number of time jumps occurring in the slave server within a preset time period is greater than a preset number threshold.

[0093] It is understandable that if the number of time jumps occurring from the server within a preset time period is greater than a preset number of times threshold, it can be determined that frequent time jumps have occurred from the server within the preset time period. In the present embodiment, whether a time jump occurs from the server within a preset time period can be determined by the server itself. For example, if more than 5 time jumps occur from the server within 10 minutes (the time changes are: A1->B1->A2->B2->A3), and the interval between each time jump is greater than or equal to 10S, then the server can determine that frequent time jumps exist within these 10 minutes.

[0094] S602: Determine a second time synchronization state according to the execution result, the current time and the time jump information.

[0095] In this embodiment, the main server parses the node information reported by the slave server, obtains the execution result of the time synchronization of the slave server, the current time of the slave server, and the time jump information of the slave server, and can determine the second time synchronization status of the slave server based on any one of the information including the execution result of the time synchronization of the slave server, the current time of the slave server, and the time jump information of the slave server.

[0096] As an optional implementation, if the execution result of the time synchronization of the slave server, the current time of the slave server, and the time jump information of the slave server meet any one of the following conditions, the master server can determine that the second time synchronization state of the slave server is an abnormal state, wherein the above conditions may include: the execution result of the time synchronization of the slave server is abnormal, the time difference between the current time of the slave server and the current time of the master server is greater than a preset time difference threshold, and the number of time jumps occurring in the slave server within a preset time period is greater than a preset number threshold.

[0097] In the present embodiment, since the master server obtains the execution result of the time synchronization of the slave server, the current time of the slave server and the time jump information of the slave server from the node information reported by the slave server, the obtained information is all related to the time synchronization information of the slave server. Therefore, the master server can accurately determine the second time synchronization state of the slave server based on the execution result of the time synchronization of the slave server, the current time of the slave server and the time jump information of the slave server, thereby ensuring the accuracy of the master server in determining the second time synchronization state of the slave server.

[0098] In this embodiment, the detailed process of determining the first time synchronization state of the master server according to the external time synchronization information of the master server and the internal time synchronization information of the master server is explained. In an exemplary embodiment, the above S202 includes:

[0099] Step A: When both the external time synchronization information and the internal time synchronization information are normal, determining that the first time synchronization state is a normal state.

[0100] In this embodiment, as described in the above embodiments, the external time synchronization information of the main server refers to the time synchronization information between the main server and servers outside the distributed storage cluster, and the internal time synchronization information of the main server refers to the time synchronization information of the main server itself. If the main server determines that the external time synchronization information and internal time synchronization information obtained are normal, it means that the time synchronization between the main server and servers outside the distributed storage cluster is normal, and the time synchronization information of the main server itself is also normal. In this scenario, the main server can determine that its first time synchronization status is normal.

[0101] In the present embodiment, since the main server determines that the first time synchronization state of the main server is a normal state when it determines that the external time synchronization information between the main server and the servers outside the distributed storage cluster is normal and the internal time synchronization information of the main server itself is also normal, both the time synchronization information between the main server and the servers outside the distributed storage cluster and the time synchronization information of the main server itself are taken into consideration, so that the main server can accurately determine the first time synchronization state of the main server; in addition, the process of the main server determining the first time synchronization state of the main server itself based on the external time synchronization information between the main server and the servers outside the distributed storage cluster and the internal time synchronization information of the main server itself is relatively simple, thereby improving the efficiency of the main server in determining its own first time synchronization state, so that the main server can promptly generate an alarm message indicating that there is a time synchronization anomaly in the distributed storage cluster.

[0102] To facilitate understanding by those skilled in the art, the alarm method provided by the present application is described in detail below. The method may include:

[0103] S1, obtaining time synchronization information of a master server in a distributed storage cluster; the time synchronization information includes external time synchronization information and internal time synchronization information of the master server.

[0104] S2, when both the external time synchronization information and the internal time synchronization information are normal, determine that the first time synchronization state of the main server is a normal state; when one of the external time synchronization information and the internal time synchronization information is abnormal, determine that the first time synchronization state of the main server is an abnormal state.

[0105] S3: When the first time synchronization state of the primary server is abnormal, generate an alarm message.

[0106] S4, when the first time synchronization state of the master server is normal, for each slave server in the distributed storage cluster, obtain the node information reported by the slave server and the time interval for reporting the node information.

[0107] S5: When the time interval is greater than or equal to the preset time period, determine that the second time synchronization state of the slave server is an abnormal state.

[0108] S6, when the time interval is less than the preset time period, obtain the execution result of the time synchronization from the server, the current time and the time jump information from the node information; the time jump information is used to indicate whether the number of time jumps occurring from the server within the preset time period is greater than the preset number threshold.

[0109] S7, if any one of the following conditions is met, the second time synchronization state of the slave server is determined to be an abnormal state; the above conditions include: the execution result is abnormal; the time difference between the current time and the current time of the master server is greater than the preset time difference threshold; the number of time jumps occurring in the slave server within the preset time period is greater than the preset number threshold.

[0110] S8, if it is determined that the second time synchronization state of any slave server is an abnormal state, an alarm message is generated and the slave server nodes in the abnormal state are displayed. When the displayed slave server nodes in the abnormal state exceed the preset number, the slave server nodes before the preset number are displayed.
