Linux server CPU, memory, disk space, load condition view python script

[This article is from the Sky Cloud-owned blog Park]

Online search, patchwork, assembled a Python script that can check Linux server CPU usage, memory usage, disk space occupancy, and load conditions.

The script reads as follows:

Touch a py file on the Linux server and paste the above into it and save it. Run the Python script with the following effect:

Glance. In the future to access the background interface 502, no return situation, in the background server to execute a script to see if this is caused by the problem, is not memory consumption is too high, is not disk full and so on. Facilitates the positioning of background server environment issues in order to contact related development or operations to assist with problem resolution.
