Can Nagio monitor a folder for files

[jboddiford]

Hi,

Very new to Nagio and evaluating it as a monitoring solution for a company.

One of the tasks we need monitored is the count of files in a folder... so basically if there are files in a folder at a specific time... it's working well... if the folder is empty... we need an alert.

Is this something Nagio can help with?

Thanks in advance!!

This should be pretty easy to do. You could make a bash script that does

Code: Select all

ls -l | grep --invert ^d wc -l

And uses that (minus 1 since the first line it outputs is not a file) for a non-recursive file count. The grep removed all directory listings, and the wc -l gives a count of the files. Then it's just a matter of giving the proper exit code based on the file count.
