monitoring the acquisition tasks of the first acquisition mode and the acquisition tasks of the second acquisition mode in real time, and acquiring and displaying acquisition task execution information;
caching the collected server cluster information into a database cache table;
and packaging and storing the server cluster information cached by the database cache table into the session object.
2. The server cluster information acquisition caching method according to claim 1, wherein the triggering mode corresponding to the first acquisition mode is: the acquisition time interval from the previous first acquisition mode reaches a preset time interval.
3. The server cluster information acquisition caching method according to claim 1, wherein the triggering mode corresponding to the second acquisition mode is: and acquiring a control command of the second acquisition mode or server cluster information change input by the user.
4. The server cluster information collection caching method of claim 1, further comprising: and responding to the request of the front-end user, and directly sending the server cluster information stored in the session object to the user interface through the interface.
5. The server cluster information collection and caching method according to any one of claims 1 to 4, wherein collecting task execution information comprises: collecting task names, collecting task starting time, collecting task ending time, collecting task execution state, collecting task execution results and collecting task execution failure reasons.
6. The server cluster information collection and caching method according to any one of claims 1 to 4, wherein the server cluster information includes CPU information, disk information, node information, and device information.
7. The server cluster information acquisition and caching method according to any one of claims 1 to 4, wherein the server cluster information cached in the database cache table is updated in real time according to the acquisition result of the first acquisition mode or the second acquisition mode; and packaging and storing the updated server cluster information cached in the database cache table into the session object.
8. A server cluster information acquisition and caching device is applied to a distributed storage system and is characterized by comprising:
the setting module is used for setting a first acquisition mode and a second acquisition mode to acquire server cluster information and correspondingly executing the first acquisition mode or the second acquisition mode according to different acquisition triggering modes; the first acquisition mode is timing acquisition, and the second acquisition mode is active acquisition;
the monitoring module is used for monitoring the acquisition tasks of the first acquisition mode and the acquisition tasks of the second acquisition mode in real time, and acquiring and displaying acquisition task execution information;
the cache module caches the acquired server cluster information into a database cache table;
and the encapsulation storage module encapsulates and stores the server cluster information cached by the database cache table into the session object.
9. An electronic device, comprising: a memory for storing a computer program; a processor for implementing the steps of the server cluster information collection caching method according to any one of claims 1 to 7 when executing the computer program.
10. A computer-readable storage medium, on which a computer program is stored, which, when being executed by a processor, carries out the steps of the server cluster information collection caching method according to any one of claims 1 to 7.
