Currently I set it to once an hour. The IO changed a lot already. I might increase this number in future though.
I am wondering though why the plugin itself does the update every time it’s called. It should have a default var that automatically only checks for updates once an hour or something like that.
I didn’t even think of the apt plugin in the first place because it didn’t make sense to me to check every few seconds/once a min for new updates. And I don’t know any other monitoring solution that does it this way. Hence my ref to the librenms apt script.
