Negation of longer strings like that requires a backtracking implementation of "regular expressions" (the quotes are there because this kind of regular expression is actually NOT a regular expression in the strict computer science sense), and is not supported by most traditional UNIX tools. Unfortunately, I'm not sure there's a good way to make this work. Hopefully someone else can come up with an alternative solution.

IO wait is difficult to identify. Using top I can read an average of 0% with some peaks up to 4%. Using iotop the process kjournald is jumping on first position often with peaks to 10-20%, back to 0 immediatly. Second place for nagios process. But the 1sec refresh is changing very often the situation. Semms really interesting your doc, also I'll try some solutions. I'll use sym links to not alter any configuration file. Should do the trick as well. I'll let you know! Thank you!

Whether Nagios is using ndoutils or not there will be a hardware limit as to how many disk writes it can handle in a given period of time. Even though you're only running a few active checks, it could be a symptom that your machine is having to wait on itself to write to disk for other things as well. The doc below is written for Nagios XI, but of a lot of the items apply to Core as well. I would consider exploring some options with a RAM disk in order to reduce disk activity. http://assets.nagios.com/downloads/nagiosxi/docs/Utilizing_A_RAM_Disk_In_NagiosXI.pdf On 5/22/2012 7:55 AM, Simone Felici wrote: ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

If you do use the DB , replicate it to a secondary DB and use that as your queries master .and trim the one nagios writes to , but make sure that if the trimming is done , the data is not removed from the replicated server. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Maybe, but not right now. For now I would like to know a way to identify (and possible solve) the actual high latency.

I wouldn't recommend that. I couldn't keep a Nagios server with under 6000 services limping along when NDOUtils was running. Eventually, the check latencies would go through the roof and the entire server would get farther and farther behind. I went to Livestatus. It took me all of 20 minutes to adjust my reports to use the new interface, and I haven't restart my Nagios daemon since (other than normal maintenance). </pre> C.

The filesystem actually resides on the SAN storage and are connected to physical servers. Let's say /home is shared among server1 and server2. When /home breaches the WARNING or CRITICAL threshold it raises two tickets, one from each server. I tried utilising the check_cluster and check_cluster2 plugins to raise only one ticket when there is a problem instead of two. I have the following definitions... "Disk Monitor /home" is being monitored on server1 and server2 using NRPE with notifications disabled. hostgroups ========== define hostgroup { hostgroup_name clustered_servers alias Clustered servers members server1,server2 } servicecluster.cfg ================== define service { service_description Clustered disk /home hostgroup_name clustered_servers check_comma</pre> Kumar, Ashish 2012-05-22T09:10:33 http://permalink.gmane.org/gmane.network.nagios.user/73761 <pre>Hello.

I've a distributed setup with a master server collecting &gt;9.000 passive services sent from other servers, all with active latencies near 0.

We are using the last version of Opsview Community like Simon although his setup sounds a bit more fault tolerant. We have 1 master server with about 30 slave servers monitoring various remote sites. Easy of distributed setup was what won us over to Opsview several years ago but as they moved the distributed version to the enterprise commercial edition I am starting to pay attention again to the different variants of Nagios out there. Also centralized web based configuration front end was another huge plus as engineers don't have to understand Nagios to setup hosts. The racoon setup sounds like some good stuff.

The monitoring is spread unevenly across the servers as most of them are in specific customer environments. We use Puppet (formally rsync) to distribute a standard set of "global" config (host / service templates etc) across all servers and each server has its own local config (hosts / services). We use SNMPTT passive checks for the networking kit, NRPE for most Nix hosts (some use SNMP checks) and NSClient++ with Microsoft servers. All based on standard Nagios core and tied together with an horrid POC intergeneration software / MQ. I did do some testing with Merlin but it was far from stable at that point and we have been waiting for Nagios 3.4.x to be released. So possible some time soon we will add Merlin. -- Ritchie &lt;--Time flies like an arrow; fruit flies like a banana. --&gt; On Fri, May 18, 2012 at 8:33 AM, Simone Felici &lt;s.felici&lt; at &gt;mclink.eu&gt; wrote: ------------------------------------------------------------------------------ Liv</pre> RichTea 2012-05-18T09:56:08 http://permalink.gmane.org/gmane.network.nagios.user/73752 <pre> Impressive :) We're monitoring ~2000 hosts and ~10000 services, every 5 minutes.
