SysDiagMonitor
Here is a sample GNU/Linux bash script that monitors a computer system and user activity regularly and logs key information. The script “SysMonitor.sh” automatically and regularly writes to a log file “SysMonitor.log”.
The log file contains time-stamped detailed information about significant changes to the
following:
-
Users currently logged in
-
Current processes
-
Top 5 CPU utilising processes
-
Devices plugged in (e.g. USB)
-
Disk usage:
-
Overall disk usage
-
The user’s home directory (/home/someuser…)
-
-
Network interfaces and their states
Highlights
- The script extracts key details about the changes to the computer system such as listed above and adds them to an ever-growing log file.
- I did not have to do any SUDO install as was achived using only common pre-installed command line tools and did not rely on additional programs / tools / libraries /.
- The log file consists of easily readable key details following popular conventional log patterns.
