Nagios Support Forum

Since 4 or 5 months ago, I've been using SNMP queries to monitor the amount of memory used by some processes on all our remote servers, hosted on external datacenters. 2 weeks ago, some of our servers started to present timeout messages: ERROR: Process name table : No response from remote host 'xxx....

Where do I set the timeout value for this message?: "(Service Check Timed Out)"
Also, how can I set a generic timeout in perl?

I will check it out.
Thanks for pointing me in the right direction.

So, it turns out that even though the "Test Check Command" returns empty output, it returns valid output (both text and status) when I use the "Schedule an immediate check". All I had to do was to set the nagios user config file. That's not a critical matter, but it would be nice...

I'm looking into it. How can I change the GUI user?

Now you've shed some light on my problem. ODBC uses a user-specific config file (~/.odbc.ini). I had it only for root, not for nagios user. I did "su -l nagios" and then tried to execute the plugin. It obviously failed until I configured the odbc.ini file for the nagios user. However, I st...

Are you saying that it works when you execute "perl <my_plugin>" or are you saying it works when you execute the SQL separately? Both. It works when I run "./check_sql.pl" on CLI. But it ignores any "print" or "exit" placed after 'DBI->connect'. How am I supp...

So I had to do my first plugin from scratch. I'm basically querying a remote Windows SQL Server from my Nagios server. It works well when executed from linux CLI (./check_sql.pl), but it returns empty output while executing from Web UI. What is really bugging me is that the output fails to be printe...

Speaking of check_mssql, is there a reason for blocking underlines at the username, like in "user_name" ? I was getting an annyoing "invalid characters in the username" until I edited the code and added a simple "\_" to the username's regex. Will there be any downside t...
