[0047] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be described clearly and in detail below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in the field based on the embodiments in the embodiments of the present invention should fall within the scope of protection of the embodiments of the present invention.

[0048] The method, device, electronic device and storage medium for real-time monitoring of performance parameters of industrial equipment according to the embodiments of the present invention are applicable to industrial equipment such as industrial switches and industrial routers. The characteristics of these devices are that they need to process data in real time and have relatively high timeliness.

[0049] The specific implementation of the embodiment of the present invention is further described below in conjunction with the accompanying drawings of the embodiment of the present invention.

[0050] Figure 1 A flow chart of a method for real-time monitoring of performance parameters of industrial equipment according to an embodiment of the present invention is shown.

[0051] like Figure 1 As shown, the method includes:

[0052] S120, setting the interval period;

[0053] In this step, different intervals may be set to meet the real-time monitoring requirements of different performance parameters. For example, a 5s interval may be set to obtain the interface traffic of the target device.

[0054] S120, acquiring the current time as a first time, and acquiring first parameter data related to the performance parameter at the first time;

[0055] In this step, the current time may be obtained as the first time by a system clock on an apparatus or electronic device that executes the method according to an embodiment of the present invention;

[0056] In this step, first parameter data related to the performance parameter at the first time is obtained, which may be first parameter data measured by a system function built into the target device or other third-party tools installed additionally; the first parameter data may be data directly representing the performance parameter, or may be data that needs to be processed, for example, by a cleaning process to obtain the performance parameter, or may even be data that needs to be converted through general routine conversion to obtain the performance parameter, wherein how to perform data cleaning processing and general conversion does not involve any part that requires creative effort, or may be implemented by a technician in this field based on general technical knowledge; therefore, it will not be elaborated here.

[0057] S130, obtaining a second time at the end of the one interval period, and obtaining second parameter data related to the performance parameter at the second time;

[0058] In this step, similar to S120, the system clock on the device or electronic device executed by the method of the embodiment of the present invention may be used to time the time. After the clock time passes a preset interval period, the current time is obtained as the second time, and the second parameter data related to the performance parameter at this time is obtained.

[0059] In this step, the second parameter data related to the performance parameter at the second time is obtained, which can also be the second parameter data obtained by measuring the built-in system function of the target device or other third-party tools installed additionally; the second parameter data can be data directly representing the performance parameter, or data that obtains the performance parameter after, for example, cleaning processing, or even data that needs to be converted to obtain the performance parameter. How to perform data cleaning processing and conventional conversion does not involve the part that requires creative efforts, or it can be achieved by those skilled in the art based on general technical knowledge; therefore, it will not be expanded here.

[0060] According to an embodiment of the present invention, the performance parameter includes one or more of an interface rate, an interface occupancy rate, a CPU occupancy rate or a memory occupancy rate.

[0061] S140: Display the first time and the performance parameter at the first time, and the second time and the performance parameter at the second time.

[0062] In this step, it can be understood that S120 and S130 are not repeatedly executed, and real-time performance parameters are monitored and obtained in real time and displayed.

[0063] Specifically, it can be displayed in an intuitive manner in the form of a broken line, so that management personnel can view in real time and intuitively obtain the trend of relevant performance parameters. Of course, it can also be displayed in other display forms, which are not limited here.

[0064] According to another embodiment of the present invention, when the performance parameter is an interface rate, the method further includes:

[0065] A first formula is preset, and the first formula is suitable for combining the first time, the second time, the first parameter data and the second parameter data to obtain the interface rate at the second time; and, based on the interval period, calculating and displaying the interface rate at the second time.

[0066] In this embodiment, the first parameter data and the second parameter data are obtained in real time based on the SNMP protocol. Of course, the first parameter data and the second parameter data can also be obtained through other types of protocols, and the applicant does not limit this here.

[0067] According to an embodiment of the present invention, the first formula is: (F2-F1)*8 / (T2-T1), where the traffic at time T1 is accumulated as F1, and the traffic at time T2 is accumulated as F2. At this time, the real-time acquired F1 and F2 are the accumulated traffic of the target device, and the unit is usually bytes, and the obtained performance parameter is the interface rate, which is usually bits / second. By presetting the formula and using the data derivation method to perform real-time data calculation, the need to wait for periodic data collection is eliminated, and data trends can be reflected more timely and accurately.

[0068] According to an embodiment of the present invention, the interface rate may include an interface uplink rate and an interface downlink rate.

[0069] According to another embodiment of the present invention, when the performance parameter is the interface occupancy rate, the method further includes:

[0070] A second formula is preset, wherein the first formula is suitable for combining the first time, the second time, the first parameter data, the second parameter data and the interface bandwidth of the target device to obtain the interface occupancy rate at the second time; and, based on the interval period, calculating and displaying the interface occupancy rate at the second time.

[0071] According to an embodiment of the present invention, the second formula is: (F2-F1)*8 / (T2-T1) / W, wherein the accumulated traffic at time T1 is F1, and the accumulated traffic at time T2 is F2. At this time, F1 and F2 obtained in real time are the accumulated traffic of the target device, and the unit is usually byte. By converting bytes, the performance parameters of the interface rate in bits / second are obtained; W represents the interface bandwidth, and the conversion is performed accordingly according to the unit of W. For example, the second formula can also be: (F2-F1)*8 / (T2-T1) / W*100. By presetting the second formula, when the interface rate is obtained in real time based on the data derivation method, the interface occupancy parameter is further calculated in real time, which provides different observation dimensions for operators.

[0072] Figure 2 The figure shows the real-time display effect of monitoring the interface occupancy rate according to a method of an embodiment of the present invention. Figure 2 As shown, the interval period is set to 5 seconds, and the current interface rate under the interval period is displayed at 14:36:48, 14:36:53, 13:36:58...

[0073] According to another embodiment of the present invention, when the performance parameter is CPU occupancy rate, the first parameter data and the second parameter data are CPU occupancy rate values ​​at a first time and a second time, respectively, without the need for calculation or processing.

[0074] Figure 3 FIG. 4 shows a real-time display effect of monitoring CPU occupancy rate according to a method of another embodiment of the present invention; Figure 3 The embodiment shown can display the CPU occupancy of more than one target device at the same time, and the interval period is set to 1 second.

[0075] According to another embodiment of the present invention, when the performance parameter is memory occupancy, the first parameter data and the second parameter data are respectively the memory occupancy values ​​at a first time and a second time, without the need for calculation or processing.

[0076] Figure 4 FIG. 4 is a flow chart showing a method for real-time monitoring of industrial equipment performance parameters according to another embodiment of the present invention; Figure 4 In the embodiment shown, the method further comprises:

[0077] S210, creating a new device type list, where the device type list includes one or more device types;

[0078] Different device types can be created according to different target devices. For example, for target devices of industrial switches, different types such as SCALANCE_XC200, SCALANCE_XM400, and SCALANCE_XR500 can be created.

[0079] According to another embodiment of the present invention, after a new device type is created, the device type can also be edited or deleted.

[0080] S220, creating a target device list under the device type, the target device list including one or more target devices;

[0081] Corresponding to the target device list under a device type, more than one target device can be newly created. For example, for the device type of SCALANCE_XC200, multiple target devices can be created. Each target device includes multiple parameters, such as: device serial number, device name, IP address, device interface and other parameters.

[0082] According to another embodiment of the present invention, after a target device is newly created, operations of editing and deleting the target device may also be performed.

[0083] S230: Select a target device and execute S120 to S140.

[0084] On the real-time data display page, you can select the target device to be monitored, or even a parameter of the target device (such as a device interface of the target device), to display the performance parameters in real time. Figure 2 As shown in the figure, by selecting an existing target device from the "Select target device" drop-down box, and clicking "Get interface", the device interface information of the target device is initialized in the "Select interface" drop-down box, and the interface to be monitored is selected from the "Select interface" drop-down box, and the interface occupancy of the relevant device interface is displayed in the real-time display diagram above. Figure 3 As shown in , performance parameter monitoring is performed by selecting a target device in the target device list from the "Select Target Device" drop-down box.

[0085] The method according to another embodiment of the present invention further includes:

[0086] S310, setting an alarm threshold value related to the performance parameter, and setting a timer, wherein the timer is pre-set with an alarm delay time;

[0087] Different alarm thresholds can be set for different performance parameters, such as Figure 2 and Figure 3 In Figure 2 The alarm threshold and response of the interface occupancy rate in Figure 3Set the alarm threshold of CPU usage in .

[0088] Set a timer to implement the alarm delay function, so that the alarm will not be triggered as soon as the alarm threshold is exceeded, but the alarm will be actually triggered after the alarm threshold is exceeded for a certain period of time.

[0089] S320, comparing the performance parameter at the current time with the alarm threshold;

[0090] According to the interval period set in the above embodiment, the performance parameters of the current time are continuously obtained, and the performance parameters are compared with the set alarm threshold.

[0091] S330: If the performance parameter at the current time reaches or exceeds the alarm threshold, trigger the timer;

[0092] In this step, if the performance parameter reaches or exceeds the alarm threshold, a timer is triggered and counts down according to the alarm delay time preset in the timer.

[0093] S340: Continue to compare the performance parameter at the current time with the alarm threshold, and issue an alarm if the time when the performance parameter reaches or exceeds the alarm threshold reaches the alarm delay time.

[0094] If the situation of exceeding the alarm threshold value continues to occur and reaches the alarm delay time set in the timer, an alarm is issued at this time, for example, an audible alarm is issued, or a highlight prompt is given on the display interface.

[0095] Based on this embodiment, a timer and an alarm delay time are set to time the time when the abnormal performance parameter is generated. Once the time when the abnormal performance parameter is generated exceeds the alarm delay time, an alarm is issued. In this way, if the performance parameter is abnormal due to accidental circumstances, the alarm will not be triggered immediately, thereby avoiding too many useless alarm messages.

[0096] Based on the above embodiment, according to another embodiment of the present invention, issuing an alarm includes:

[0097] Collect alarm data, wherein the alarm data includes a timestamp and the performance parameter corresponding to the timestamp; generate a visualization chart based on the alarm data; and construct and send the email content.

[0098] In this embodiment, the monitored abnormal data is collected, and then a visual chart is generated, such as a real-time rate line chart, and then an email content including alarm data, visual chart, target device information, etc. is constructed and sent to relevant setting personnel to complete the notification.
