For example: the acquiring unit 111 employs a command: PID = ' ps-fC java | grep "$ INSTANCES" | egr "NamessrvStartup | BrokerStartup" | awk ' { print $2} ', and a running result can be obtained: [ root @ SZC-L0075300 Rockettmq ] # ps-fC java | grep "rmq _ LCloud-config-prd-ins5201" | egrep "NamesrvStartup | BrokerStartup" | awk '{ print $2}'16056, so the acquisition unit 111 can determine the PID of the RockettMQ process to be 16056.
The accessing unit 112 accesses the state data in the file system process attribute information directory of the rockmq according to the PID.
In at least one embodiment of the present invention, the file system process attribute information directory is a system file of the rocktmq, and all state data is stored in the file system process attribute information directory;
wherein the status data comprises one or more of the following in combination:
process name, running state, PID, thread count.

Specifically, the configuration access command is/proc/$ process ID/status, the accessing unit 112 adds the PID to the configuration access command, generates a target path/proc/PID/status, and accesses the state data in the file system process attribute information directory according to the target path.
For example: the access unit 112 may generate a target path/proc/16056/status according to the PID 16056 to access the status data of the process with PID 16056.
The retrieving unit 113 retrieves the rockmq current thread number from the state data in conjunction with the specified key.
In at least one embodiment of the present invention, each of the state data corresponds to a key, for example: the key word of the process Name is Name, and the key word of the running State is State.
Further, the specified keyword corresponds to the current thread number, and the specified keyword comprises Threads.
Further, the retrieving unit 113, in conjunction with the specified key, retrieves the current thread number of the rockmq from the state data, including:
the calling unit 113 matches the specified keyword with all keywords in the status data to obtain a matched keyword, and obtains a parameter value corresponding to the matched keyword from the status data as the current thread number.
For example: the fetch unit 113 may form an instruction rmq _ Threads () according to the specified keyword Threads, and further obtain the current thread number matching the specified keyword Threads from the state data.
In at least one embodiment of the present invention, after the retrieving unit 113 retrieves the current thread count, the current thread count is stored in a configuration database, so as to facilitate retrieval.
Specifically, the configuration database may be a local database of the electronic device, or an external database in communication with the electronic device, or the like.
Further, after the display unit 114 saves the current thread number to the configuration database, the retrieving unit 113 may retrieve the current thread number from the configuration database, and the display unit 114 displays the current thread number to the user, so that the user can directly view the current thread number.
Specifically, the displaying unit 114 displays the current thread number, including:
the presentation unit 114 presents the current thread count through the Grafana presentation platform.
Specifically, the Grafana display platform is a visualization panel (Dashboard), supports various diagrams and layout displays, and supports Graphite, zabbix, influxDB, prometheus and OpenTSDB as data sources. The Grafana display platform has the following characteristics: the method has flexible and rich graphical options, can mix various styles, supports day and night modes and supports a plurality of data sources.
At this time, the configuration database may be a non-relational database of the Grafana display platform, so as to avoid occupying an operating memory of the electronic device.
Of course, in other embodiments, the presentation unit 114 may also present the current thread number through Highcharts, which is not limited by the present invention.
The Highcharts is a diagram library written in pure JavaScript language, can be added with interactive diagrams on a web site or a web application program simply and conveniently, and supports various diagrams of a monitoring platform.
Preferably, the method further comprises:
the obtaining unit 111 obtains the configured thread number of the rocktmq, the calculating unit 115 calculates a first difference between the configured thread number and the current thread number, and calculates a ratio of the first difference to the configured thread number, and when the ratio is greater than or equal to a first configuration value, the sending unit 116 sends an alarm.
Specifically, the configuration thread number is the maximum number of threads that the RocketMQ can run.
The first configuration value is a preset threshold value, and the first configuration value may be configured according to the performance of the electronic device, or may be configured by the user according to actual requirements, which is not limited in the present invention. For example, the first configuration value may be 80%, etc.
Thus, when the ratio is greater than or equal to the first configuration value, it indicates that the current thread count is too high, and if no action is taken, the operation of the electronic device will be affected, and therefore, the issuing unit 116 issues an alarm.
Preferably, the method further comprises:
the testing unit 117 performs a pressure test on the electronic device to obtain a simulated thread number of the RocketMQ, the calculating unit 115 calculates a second difference between the current thread number and the simulated thread number, and the sending unit 116 sends an alarm when an absolute value of the second difference is greater than a preset threshold.
Specifically, the pressure test is to simulate an actual use scenario of the electronic device to realize a simulation test of an actual operation index of the electronic device.
Further, the preset threshold value is used as a reference for comparison, and may assist in determining whether the thread number is abnormal, for example: the preset threshold may be 5%, etc.
In this embodiment, the testing unit 117 simulates the operation of the rocktmq, obtains the simulated thread number, further calculates a second difference between the current thread number and the simulated thread number, and when an absolute value of the second difference is greater than the preset threshold, indicates that the electronic device may operate abnormally due to a large difference between the simulated value and the actual value, and further sends an alarm to prompt related personnel to handle the abnormal condition of the rocktmq thread number in time.
In summary, in the present invention, when a rockmq thread number monitoring instruction is received, the running state of the rockmq is detected; when the running state is available, a PS command is adopted, and the specified keywords are combined, so that the PID of the RocktMQ process is obtained from all running processes; accessing state data in a file system process attribute information directory of the RocktMQ according to the PID; calling the current thread number of the RocktMQ from the state data by combining with a specified keyword; and saving and displaying the current thread number. Therefore, the invention can enable related workers to find abnormality and respond in time, further improve the operation and maintenance efficiency, and simultaneously avoid the system blockage phenomenon, thereby resulting in slow system operation and improving the user experience.
