Re: Monit - file checks with reminders

[Ron Kelley]

Just to follow up on this.  I started monit with the "-v" flag (verbose), and 
this is what I get in the monit.log file:

'MegaRAID' content match skipped - file size nor inode has not changed since 
last test

It seems monit is having an issue noticing the file has been updated.  My 
script overwrites the MegaRAID.log file each time the cron job is run.  From 
the monit man page:

FILE CONTENT TESTING
--------------------
The content is only being checked every cycle. If content is being added and 
removed between two checks they are unnoticed
On startup the read position is set to the end of the file and Monit continue 
to scan to the end of file on each cycle. But if the file size should decrease 
or inode change the read position is set to the start of the file.


Unless I read this wrong, the alert should be raised because the content of the 
file changed.


Thanks.
