This article introduces the "Linux system server inspection content and operation" related knowledge, in the actual case of the operation process, many people will encounter such a dilemma, then let the editor lead you to learn how to deal with these situations! I hope you can read it carefully and be able to achieve something!
The specific contents of the inspection are explained here:
1. CPU occupancy rate
Check script: top shift+m c
The parameter to be recorded here is?% us. It is recommended to wait a few seconds to see the dynamic changes before recording.
Cpu occupancy rate
2. Memory utilization
Check script: free-m / free- g
Memory utilization
The key thing to look at here is whether the swap memory is used. What you need to record is the second one in the second line. The ratio of it to the total memory is the memory usage. Whether to use-m or-g depends on the memory size of the server.
3. Hard disk utilization
Check script: df
Hard disk utilization
Disk utilization depends on the disk utilization itself. Here, if the application under the server uses the mounted disk separately, you also need to check the utilization of the mounted disk separately.
4. Igamo is idle
Check script: iostat-xm
I am idle
The value that needs to be recorded is the red box in the picture,?% idle, and this is Imax O idle. Here you can use iostat-xm 1 to dynamically view multiple values and then take a more average one.
5. Application health status
Check to see if the page of the application is normal and whether the user is using it properly.
6. Application service status
Check script:. / Application Service status
Check to see if the service status is running.
7. Whether there is any error in the application service operation log
Check script: cat Application Service running Log | grep ERR
Visually check whether there are any errors in the log of the application service. You can also directly open it here to check:
Vim Application Service run Log
Then use "/ ERR" to check the error report
8. Whether there is any error in the application content log
Check script: cat application content logging grep ERR
9. Data file size
First, open the directory where the application data file is located, and then run: du-sh *
Here you can see the size of all the files in this directory.
10. Archive file status
This is a special function of the application I am responsible for, which can be archived, and all of you can ignore this requirement.
11. Backup implementation
Check the backup directory to see if the latest date of the backup is recent.
