Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the following detailed description of the embodiments of the present application will be given with reference to the accompanying drawings. However, those of ordinary skill in the art will understand that in various embodiments of the present application, numerous technical details have been set forth in order to provide a better understanding of the present application. However, the claimed application may be practiced without these specific details and with various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not be construed as limiting the specific implementation of the present application, and the embodiments can be mutually combined and referred to without contradiction.
Referring to fig. 1, one of the step flowcharts of the read control method provided by the embodiment of the present application is shown, where the method may include:
step 101, receiving a target log entry sent by the baseboard management controller, wherein the target log entry is generated when the baseboard management controller detects that the data of the non-volatile node of the external device changes.
The baseboard management controller in the embodiment of the application is a system independent of a CPU, is a special controller for monitoring and managing a server/switch, and has the main functions of: device information management: recording server/switch information (model, manufacturer, date, production and technology information of each component, chassis information, main board information, etc.), BMC information (server/switch hostname, IP, BMC firmware version, etc.); server state monitoring management: detecting and managing the health states of the temperature, voltage and the like of each component (CPU, memory, hard disk, fan, frame and the like) of the server/switch; remote control management of servers/switches: powering on and powering off, restarting, maintaining, updating firmware, installing a system and the like of the server; maintenance management: log management, user management, BIOS management, alarm management, etc. Therefore, the CPU is required to manage the external device of the server/switch, and cannot access directly, and the BMC is required to provide a corresponding interface for access, where the interface provided by the BMC may be a RESTful API or an IPMI interface, and the present application is not limited herein specifically.
The CPU reads the data of the external equipment, such as the temperature value, the fan rotating speed, the power supply voltage and the like of the variable node, and the data of the non-variable node, such as the on-site information, FRU information and the like, which are rarely changed, of the equipment, because the read speed is very slow in the BMC part and the related peripheral equipment is very much, the content required to be read by each peripheral equipment is very much, and the complete read is often carried out for a plurality of minutes, the embodiment of the application limits the read of the data of the non-variable node, and the CPU is informed of the read of the data of the non-variable node only when the change of the data of the non-variable node is detected, and in addition, the substrate management controller detects the change of the data of the non-variable node of the external equipment, so that the problem of relatively large delay caused by the read judgment of the CPU can be effectively avoided.
It should be noted that, because the data of the non-volatile node is information that is rarely changed, when these data are changed, the level of the log is changed, usually, a warning level or a serious level, and the embodiment of the present application distinguishes the changed non-volatile node data and the unchanged non-volatile node data based on the change of the log level, and uses the log entry of the level corresponding to the changed non-volatile node data as the target log entry that needs to be received by the CPU.
Step 102, updating the state database according to the target log entry.
In the embodiment of the application, after receiving a target log entry, a CPU sends the target log entry to a first log file of the CPU, then converts the target log entry into target field information of the first log file according to a preset rule, so that the first log file of the CPU changes, then matches the field information in the first log file of the CPU through an Rsyslog plug-in added to the CPU, and when the Rsyslog plug-in has preset characteristic information in the field information matched to the first log file of the CPU, triggers a write state database, specifically, updates the state database according to the target log entry, the method comprises the following steps:
the target log entry is sent to a first log file, and target field information of the first log file is generated;
triggering a writing state database through the target field information. Wherein triggering a write status database via the target field information comprises:
and triggering a writing state database under the condition that the target field information is detected to be consistent with preset characteristic information, wherein the preset characteristic information is stored in an Rsyslog configuration file issued by a CPU (Central processing Unit).
It should be noted that, the preset rule is set by the acquired module information of the non-volatile node and the level information of the log, and the preset rule can set different field information according to different information carried by the target log entry, for example, the data change of the non-volatile node of different modules can be identified by the field information of a digital type, the different level information of the target log entry can be identified by the field information of a letter type, the preset feature information is set in an Rsyslog configuration file issued by the CPU end, and the preset feature information basically covers the target field information converted by the preset rule from the log file of the data change of all the non-volatile nodes.
And step 103, responding to the updating operation of the state database, and reading the data of the non-volatile node corresponding to the target log entry from the baseboard management controller.
In the embodiment of the application, the data of the non-volatile node of the baseboard management controller is read through the original daemon locally of the CPU, wherein the daemon is a special process running in the background and used for executing specific system tasks. Many daemons start up at system boot time and run until the system is shut down, others start only when needed, and end automatically after completion of the task. The daemon process in the embodiment of the application is initially started along with the system start, then does not read the data of the non-volatile nodes at regular intervals, but keeps waiting until the data of the non-volatile nodes are changed and can not trigger the reading again.
Specifically, in response to an update operation of the state database, reading data of a non-volatile node corresponding to a target log entry from the baseboard management controller, including:
responding to the update operation of the state database, and triggering the reading operation of the local daemon;
and reading the data of the non-volatile node corresponding to the target log entry from the baseboard management controller through the reading operation.
According to the reading control method provided by the embodiment of the application, the target log entry sent by the baseboard management controller is received, so that the baseboard management controller detects the data change of the non-volatile node of the external device, the problem of relatively large delay in reading by the CPU is avoided, the state database is updated according to the target log entry, the CPU determines that the data of the non-volatile node of the external device managed by the baseboard management controller at the moment changes, and the data of the non-volatile node corresponding to the target log entry is read from the baseboard management controller in response to the updating operation of the state database, so that the CPU reads the data only when the data of the non-volatile node of the external device managed by the baseboard management controller is determined to change, and unnecessary consumption of the CPU is reduced. According to the embodiment of the application, the substrate management controller detects the change of the data of the non-volatile node of the external device to avoid the delay of CPU reading, and the target log entry carrying the data change information of the non-volatile node is updated to the state database of the CPU, so that the CPU can read the data only when the data of the non-volatile node of the external device managed by the substrate management controller changes, unnecessary consumption of the CPU is reduced, and the burden is reduced for the BMC with weaker performance.
Referring to fig. 2, a flowchart of step 101 of a read control method provided by the embodiment of the present application shown in fig. 1 is shown, and specifically includes:
step 201, send Rsyslog configuration file to baseboard management controller.
The Rsyslog configuration file of the embodiment of the application is issued to the baseboard management controller through the CPU, so that the Rsyslog of the baseboard management controller can synchronize the log entries meeting the conditions to the CPU, wherein the Rsyslog configuration file can control the output of different types of logs by modifying parameters, can set the level of the logs according to different conditions, and can send the log entries meeting the conditions to a target position by making rules.
In addition, because the data of the non-volatile node changes, a log entry is locally generated by the Rsyslog service of the baseboard management controller, so that the CPU end sends the Rsyslog configuration file to the baseboard management controller in order to monitor the data change of the non-volatile node of the external device of the baseboard management controller.
It should be noted that, because the external device of the baseboard management controller has both the data of the non-volatile node and the data of the volatile node, in order to avoid the interference of the data of the volatile node to the data of the non-volatile node, the data of the volatile node and the data of the non-volatile node are respectively put into different Cache registers on the baseboard management controller for storage.
Step 202, receiving a target log entry sent by the baseboard management controller through the Rsyslog configuration file.
In the embodiment of the application, the CPU sends the Rsyslog configuration file to the baseboard management controller, so that when the Rsyslog at the baseboard management controller side has the log entry meeting the condition, the Rsyslog at the CPU side is sent to the log entry, and the condition can be set through the grade of the target log entry, for example, when the grade of the log is a warning grade or a serious grade, the Rsyslog is used as the target log entry to be sent to the CPU side.
According to the reading control method provided by the embodiment of the application, the target log entry sent by the baseboard management controller is received, so that the baseboard management controller detects the data change of the non-volatile node of the external device, the problem of relatively large delay in reading by the CPU is avoided, the state database is updated according to the target log entry, the CPU determines that the data of the non-volatile node of the external device managed by the baseboard management controller at the moment changes, and the data of the non-volatile node corresponding to the target log entry is read from the baseboard management controller in response to the updating operation of the state database, so that the CPU reads the data only when the data of the non-volatile node of the external device managed by the baseboard management controller is determined to change, and unnecessary consumption of the CPU is reduced. According to the embodiment of the application, the substrate management controller detects the change of the data of the non-volatile node of the external device to avoid the delay of CPU reading, and the CPU updates the target log entry carrying the data change information of the non-volatile node to the state database of the CPU, so that the CPU can read the data only when the data of the non-volatile node of the external device managed by the substrate management controller changes, unnecessary consumption of the CPU is reduced, the burden on the BMC with weaker performance is reduced, and meanwhile, the Rsyslog configuration of the substrate management controller is issued by the CPU, so that the appointed log information can be synchronized to the CPU end.
Referring to fig. 3, a second step flowchart of a read control method provided by an embodiment of the present application is shown, which specifically includes:
in step 301, a local daemon is started in response to the start of the CPU.
In the embodiment of the application, the local daemon process is started by default when the CPU is started for the first time.
Step 302, the daemon reads data of an initial non-volatile node of the external device.
After the local daemon of the CPU in the embodiment of the application is started, the data of the initial non-volatile node of the external equipment can be read. In addition, because the external device comprises volatile node data and non-volatile node data, the data of the volatile node needs to be updated frequently, a fixed updating period is set, the volatile node data of the external device is read periodically according to the updating period, the non-volatile node data is not easy to change, and therefore the local daemon of the CPU only reads the data of the initial non-volatile node when the CPU is started for the first time and then keeps waiting, and the non-volatile node data of the external device cannot be read periodically according to the updating period.
Step 303, subscribing to a status database.
In the embodiment of the application, after the daemon process of the CPU reads the data of the initial non-volatile node of the external equipment in the baseboard management controller at the initial starting, the data of the non-volatile node is not read at regular intervals but is waited for in the background operation, but in order to trigger the reading again when the data of the non-volatile node of the external equipment in the baseboard management controller changes later, a state database is arranged at the CPU end, the change of the data of the non-volatile node of the external equipment in the baseboard management controller is monitored through the state database, and the state database is required to be subscribed in order to confirm the monitoring result of the state database.
And step 304, under the condition that the update event exists in the subscribed state database, reading the data of the non-volatile node of the current external device from the baseboard management controller.
The subscription in the embodiment of the application is a method for acquiring the latest data of the state database in real time at low cost, and because the rsyslog plug-in of the CPU triggers writing the state database when receiving the matching of the specific log entry, the standby daemon is operated in the background to trigger the re-reading operation after subscribing to the update event of the state database through the subscription state database, and the data of the non-volatile node of the current external device is read from the baseboard management controller.
According to the reading control method provided by the embodiment of the application, the target log entry sent by the baseboard management controller is received, so that the baseboard management controller detects the data change of the non-volatile node of the external device, the problem of relatively large delay in reading by the CPU is avoided, the state database is updated according to the target log entry, the CPU determines that the data of the non-volatile node of the external device managed by the baseboard management controller at the moment changes, and the data of the non-volatile node corresponding to the target log entry is read from the baseboard management controller in response to the updating operation of the state database, so that the CPU reads the data only when the data of the non-volatile node of the external device managed by the baseboard management controller is determined to change, and unnecessary consumption of the CPU is reduced. According to the embodiment of the application, the time delay of CPU reading is avoided by detecting the change of the data of the non-volatile node of the external device through the baseboard management controller, and the CPU realizes the reading of the data only when the data of the non-volatile node of the external device managed by the baseboard management controller changes by updating the target log entry carrying the data change information of the non-volatile node to the state database of the CPU, so that unnecessary consumption of the CPU is reduced, the burden on the BMC with weaker performance is reduced, and meanwhile, the daemon subscribes to the state database to trigger the re-acquisition of the data of the non-volatile node on the baseboard management controller, thereby effectively reducing the consumption of the CPU.
Referring to fig. 4, a third step flowchart of a read control method according to an embodiment of the present application is shown, and specifically includes:
the read control method of the embodiment of the application comprises a baseboard management controller and a CPU, wherein the baseboard management controller reads data of a non-volatile node of an external device after being started, the CPU injects an Rsyslog configuration file into the baseboard management controller after being started, when the configuration file is changed, the Rsyslog starts to synchronize target log entries conforming to conditions to the Rsyslog of the CPU, target field information of the CPU log file is generated according to the target log entries, the Rsyslog of the CPU is started at the moment, after confirming that the conforming target field information is received, the CPU is put into a state database, at the moment, a subscribed state database generates an update event, a re-read operation is triggered, at the moment, the non-volatile node acquires a daemon, reads the data of the current non-volatile node, wherein the CPU starts the daemon for the first time, the operation of immediately reading the data of the non-volatile node is triggered, then the daemon needs to subscribe the state database again, after the state database generates an update event, the re-read operation non-volatile node is triggered to acquire the daemon, and the data of the current non-volatile node is read again.
