Involved Software: nagios (core Version 3.5.1), powershell (6.0.2)
Problem:
When a powershell-script is run (on the beforementioned server) by the nagios service (in the context of the user "nagios") the powershell-instance creates a directory in /tmp but never deletes it. This results in the filesystem running out of INodes after about 2.5 days. With ps -ef I can see that the following command is executed by nagios: /usr/bin/pwsh -noni -nop -nol -ep Unrestricted /usr/local/nagios/libexec/[script name].ps1 [command line parameters] (I replaced the concrete names and arguments for the script because they contain sensitive data).
See result of dir -Directory in Powershell
See Content of example temporary directory
I think the Directory-names are the host-instance-ids like in Get-Host in powershell.
Question:
What arguments do I need to supply to powershell so that it deletes the temporary directories on Exit? Or even better: What Arguments do I Need to supply to powershell so that it uses the nagios-home-directory /home/nagios for storing profile data?
EDIT: I since implemented a workaround via cron and a small script which deletes all folders in /tmp once an hour. Clearly this is no solution.
