It's always better to do that with perfdata... You have the choice to also take the output as source to parse, although I strongly recommend to use perfdata. That's what it is for. > > What would the map rule look like that would do the following? > > 1. Begin with "PROCS OK:" > 2. End with "args 'apache'" > 3. Extract only the numeric value before the word processes? The regex would look something like this: /output:PROCS.*:(\d+) processes.*/ assuming that you don't care about the args and the status (OK, WARNING, CRITICAL) part. Only the digit (11) would be taken out of the output in this case. -- Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.

[Nagios-users] Trying to figure out the PCRE expression for Nagiosgraph Map
I'm writing a pcre rule for a nagios map file. The output for one query would be: PROCS OK: 11 processes with args 'apache' What would the map rule look like that would do the following? 1. Begin with "PROCS OK:" 2. End with "args 'apache'" 3. Extract only the numeric value before the word processes? Assuming it would be a nested regex within the regex. So basically, the map regex would only return 11, but enforce the rules above? Just trying to understand the logic behind this. Thanks. -- Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.

Usually people want to solve passive checks by arranging a single target ip or hostname to send to and then add peered nodes at that tier as necessary, so as to not have to send checkresults to multiple nodes from all the monitored machines. -- Andreas Ericsson andreas.erics...@op5.se OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 Considering the successes of the wars on alcohol, poverty, drugs and terror, I think we should give some serious thought to declaring war on peace. -- Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.

Merlin would do exactly that if you set one of the nodes as a poller but having all hosts assigned to it. When the poller goes down, the master will by default take over checks for it. Merlin is actually pretty well documented, but as textfiles that you have to read the oldschool way. If there's anything you find lacking from the HOWTO document or the README, please let me know and I'll amend it. > > Does anyone out there have a workable way to get an active/standby or > active/active Nagios setup?
