I would look into MK_Livestatus as a backend. This would allow you to "cluster" web frontends, and by simply replicating config files across nodes, you could have "cold" standby servers in case the backend(s) actually fail.

Notifies are sent when max_check_attempts have been made, and the service is then in a "hard" state. Notifies are also sent when a hard-failing services is rechecked (at "check_interval"), and at least notification_interval has passed since the last notify.

I've thought several times of doing it but never actually get started although I have it all planned out kinda like you. In the mean time my HA setup which I've done for several customers involves config synced using git or svn (script run by cron that checks if its something new and then restart nagios if config passes tests). Both servers doing checks but config is such that for one server all notifications are disabled except for cross-checking of the other nagios This is achieved by having common template from which all services are derived and this template is in a file specific to each server and so one has notifications disabled and the other enabled. This is not a full HA in a way that if one server dies you have to execute a script that would enable the other servers for notifications (this can be done automatically too but I prefer people to do it). > However this would be too much work if someone else has already found > an equivalent solution. > > I've looked at Merlin but it doesn't seem to do what I'm after (and > the documentation is practically nonexistant - much the same as the > NEB API documentation, in fact).

The more complexity to the monitor, the more chance you'll be chasing monitoring issues rather than site issues. And everthing you add on top of the monitor also needs to be monitored. So somehow that F5 is going to need an out-of-band monitor because if it dies then your Nagios host may well not have a way to contact you about it unless you've dual homed it which brings up a whole other set of issues. The closest I got to HA at my last gig was creating a CNAME for the active Nagios host so in a failover you point the CNAME to the new box and at least passive checks can still roll in (after DNS timeout of course, which I say is better than reconfiging every NSCA clent). -f On Thu, 9 May 2013, Steve Shipway wrote: > Date: Thu, 9 May 2013 09:19:17 +0000 > From: Steve Shipway <s.ship...@auckland.ac.nz> > Reply-To: Nagios Users List <nagios-users@lists.sourceforge.net> > To: "nagios-users@lists.sourceforge.net" <nagios-users@lists.sourceforge.net> > Subject: [Nagios-users] High Availabilty with Nagios > > Does anyone have an HA setup for Nagios that works? > > I'm thinking of creating a NEB module that will link two Nagios setups, and > replicate over all > status changes, config changes, downtime, comments, etc etc and then set the > 'standby' Nagios to > be checks/notifications disabled when in standby mode, and enabled when in > active mode.?

Then put the two > behind a failover load balancer (F5, Foundry or apache reverse proxy). We use rsync (run out of cron every minute) and a floating VIP between two hosts. Nagios is running on only one host at a time. It's a trivial (manual) process to switch between hosts. Files which are synced: all Nagios files except logs and transient results. Files synced include Nagios configs, binaries and CGIs, helper apps, plugins, local plugins and NRPE configs, docs, HTML files, status files, all files in ~nagios, and the crontab for user nagios. -- Jim ------------------------------ Message: 12 Date: Fri, 10 May 2013 10:57:28 +0200 From: Andreas Ericsson <a...@op5.se> Subject: Re: [Nagios-users] High Availabilty with Nagios To: supp...@crazynetwork.it, Nagios Users List <nagios-users@lists.sourceforge.net> Message-ID: <518cb678.1080...@op5.se> Content-Type: text/plain; charset=ISO-8859-1; format=flowed On 2013-05-09 11:50, Supporto Tecnico - Crazy Network wrote: > I would be interested too, i'm actually using merlind for this right > now, but i would like to dont have for example double notifications if a > server goes down.. and i do want both nagios set for notify, since if > one is down (for any reason) the other one should be able to check and > notify and vice-versa.... > Double notifications is a bug, unless you send passive checkresults to both masters, in which case it's by design. 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. ------------------------------ Message: 13 Date: Fri, 10 May 2013 10:58:12 +0200 From: Andreas Ericsson <a...@op5.se> Subject: Re: [Nagios-users] High Availabilty with Nagios To: Nagios Users List <nagios-users@lists.sourceforge.net> Message-ID: <518cb6a4.4040...@op5.se> Content-Type: text/plain; charset=ISO-8859-1; format=flowed On 2013-05-09 11:19, Steve Shipway wrote: > Does anyone have an HA setup for Nagios that works? > > I'm thinking of creating a NEB module that will link two Nagios > setups, and replicate over all status changes, config changes, > downtime, comments, etc etc and then set the 'standby' Nagios to be > checks/notifications disabled when in standby mode, and enabled when > in active mode.

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.

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. ------------------------------ Message: 15 Date: Fri, 10 May 2013 23:11:42 +0200 From: Claudio Kuenzler <c...@claudiokuenzler.com> Subject: Re: [Nagios-users] Trying to figure out the PCRE expression for Nagiosgraph Map To: p...@psk.net, Nagios Users List <nagios-users@lists.sourceforge.net> Message-ID: <caf-yqgiw6aj_w_qurdzrk-6ptcaw+_jfzvfkbau6sdcui9j...@mail.gmail.com> Content-Type: text/plain; charset="iso-8859-1" > The output for one query would be: > > PROCS OK: 11 processes with args 'apache' > Well first of all you'd have to make sure that nagiosgraph also takes the output in account. 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.

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. -------------- next part -------------- An HTML attachment was scrubbed... ------------------------------ Message: 16 Date: Sat, 11 May 2013 13:24:27 +0200 From: Jonas Meurer <jo...@freesources.org> Subject: Re: [Nagios-users] servicegroup overview not restricted for htaccess users To: nagios-users@lists.sourceforge.net Message-ID: <518e2a6b.3090...@freesources.org> Content-Type: text/plain; charset=ISO-8859-1 Hello, Am 06.05.2013 10:42, schrieb Jonas Meurer: > I fear that I discovered a security issue in Nagios 3.4.4 status.cgi: no comments on that? > All htaccess users, even if not listed in any authorized_for_* config > option, have full access to service group overview, summary and grid: > /nagios/cgi-bin/status.cgi?servicegroup=all&style=overview > /nagios/cgi-bin/status.cgi?servicegroup=all&style=summary > /nagios/cgi-bin/status.cgi?servicegroup=all&style=grid > > I hope that this is not intended.

So to make more sense of the whole thing, the only thing that is taken into account is the actual numerical value? In other words, it's automatically parsed? This is what I wasn't sure of. Here is the entry in the mapfile I was using: I guess the reason I'm having issues with this is the following snippet from the nagiosgraph.log: Fri May 10 12:57:51 2013 insert.pl warn output/perfdata not recognized: hostname:mymachine servicedesc:Apache Processes output:PROCS OK: 11 processes with args apache perfdata: the problem is there is no perfdata and the rrd file isn't being populated, (and obviously, no graph). I'm attributing this to the fact that the map file entry is wrong. This is really where my problem lies. Am I looking in the wrong place? Thanks.
