Automatic Inspection of multiple servers based on shell script

Summary:

Operation and maintenance service has more than 20 (or more) servers in a project. The daily performance inspection of the server is to check whether the server's CPU, memory and disk space are within the normal range. Do the same repetitive work every day or every fixed time period like this. In order to simplify the repetitive work, I wrote an automatic inspection script based on liunx server, which can be automatically executed at a fixed time in crontab, so as to reduce the manual repetitive work.

Environment:

The main servers on my project are LINUX and AIX, with a total of about 30 servers. The current workload is to patrol twice a week, manually logging in to each server and using the appropriate commands to view server performance parameters.

Train of thought:

1. All the networks between the servers are in the same local area network, and all the networks are connected to each other.

2. Choose a server with relatively good performance or less running pressure as the patrol server.

3. Through this server to realize the inspection of other servers, and then record the inspection results to the inspection server.

4. The inspection results of each server are distinguished by time and ip. Finally, all the inspection results are compressed and packaged.

5, each time the maintenance personnel only need to pick up the package regularly to check the final result, eliminating the need to log in to each server and enter the same command to view.

The inspection of the script is based on the TELNET service, so the server being tested must turn on the TELNET service.
