Is there a way to walk the entire mib with check_snmp? Not easily, nor would one want to. For a check to be useful it needs to check one datum (if it's a simple check) to compare to the threshold data; if you're custom-writing an SNMP check then you can query for multiple OIDs and then make decisio...

Not all macros are available at all times and for all possible uses. Check the manual page for macros for the matrix that states what's available where and when. It is quite possible that the $SERVICESTATE$ macro may not be available for the action_url statement as, I believe, those are "cast i...

It's time to round up the "usual suspects": 1) Is the active system set to obsess over hosts? 2) Is the non-working host somehow disabled from obsessing on the active system? 3) Is the non-active (the receiving system) globally set up to accept passive host checks? 4) Is the non-active sys...

As a test case for this, what you might try doing is sending the output (including all the macros you wish to test) to a file instead of the program. That'll tell you if they have data in them. Is the contact actually correctly defined with an e-mail address? If that datum is somehow missing then it...

First and foremost, heed mguthrie's advice; that'll tell you if your schedulers are "stalling". Besides, I am using pnp4nagios and ndouitls for storing data on MySQL. How is the performance on your MySQL server? Are you seeing lots of "slow queries"? If so, that may be stalling t...

In this case it sounds very much like the device you're querying doesn't support the particular OID you're asking for. The community string is correct, else the check would have timed out. What happens if you hit the device in question with a directed query for that OID? If you walk (or bulkwalk) th...

You may want to investigate the various macros that ara available to the notification plugins, specifically $CONTACTNAME$ and $CONTACTGROUPMEMBERS$ . Note that if you are transmitting to a mailling list there is no way for Nagios to know who is subscribed to that list unless one writes another plugi...

There are a couple of things you can try to do. 1) Try to set sendmail to not log connections that do not do anything or, 2) Write a custom plugin that actually *does* something every time it runs (e.g. VRFY e-mail@domain.TLD), but that's likely to log something as well and you're back to square one...

Step one in this will be to fix the errors that are called out when verifying the configuration. It seems you have a contactgroup called out in the configuration that is not defined anywhere. Step two will be to disambiguate what locations your web-server configuration is pointing to; from the sound...

An alternative to doing an initial "omnibus" check that takes a command-line argument to define the actual check might be to write separate ones first, prove them out individually, and then bundle them into one large script. This'll keep your development space clean from other non-related ...
