[Nagios-users] Monitoring clustered services
Hello fellow Nagios users, I have configured a couple of hosts in Nagios, since they are the nodes of a HA cluster the services are running on the active host only. As obvious Nagios is showing the services down on the passive host. I tried using check_cluster and check_cluster2 but due to the lack of information around the web and mailing list archives I couldn't figure out how it can be configured. Would anyone actually using check_cluster like to lend me a hand? :) We are using Nagios Core 3.2.0 on Centos.

Re: [Nagios-users] Monitoring clustered services
Hello Ashish, is there a virtual IP adress connected with the service (like the package IPs in ServiceGuard) ? If there is: simply monitor the service by using the IP associated with the service and monitor the individual hosts, the service might be running on. You may want to monitor and notify the hosts using the check_cluster plugin. check_cluster is useful for active/active clusters. In active/passive clusters you'll get a lot of red services and that is probably not what you want and the reason for your question.

Re: [Nagios-users] Monitoring clustered services
Might want to look into see if negate works for that plug in which will alert when a service is up. I use that on an snmp plug in that I use to check windows services on two passive nodes that should not have certain application services running. May not work for your cluster plug in but worth looking into On Oct 12, 2011 9:10 AM, Kumar, Ashish xml.de...@gmail.com wrote: Hello fellow Nagios users, I have configured a couple of hosts in Nagios, since they are the nodes of a HA cluster the services are running on the active host only.

Re: [Nagios-users] Monitoring clustered services
Hi,
One way to use check_cluster is :
first : define a command like
define command {
command_name check_cluster_service
command_line $USER1$/check_cluster -s -d $ARG1$ -c $ARG2$
}
then define your check
define service {
...
check_command check_cluster_service!$SERVICESTATEID:node1:ha_service
$,$SERVICESTATEID:node2:ha_service$!1
...
}
This will get the result of the tests of the ha_service on node1 and
node2 and return a critical state if there is more than 1 check in a
non-OK state.
But the best way to check a cluster is to check only the system (disk,
CPU, ...) on your nodes and check the cluster as if it is a classic
server through th VIP.

Re: [Nagios-users] Monitoring clustered services
One solution to that problem is to use Mathias Kettner's check_mk and use its clustered service support: http://mathias-kettner.de/checkmk_clusters.html That's what I do here. Another alternative is to create a third 'host' in Nagios representing the cluster and monitor the services on that, and not on the 'physical' boxes.

Re: [Nagios-users] Monitoring clustered services
Quoting Michael Friedrich michael.friedr...@univie.ac.at:
Hi Ashish,
Try to configure cluster resource under a new virtual host in nagios.
define host {
host_name cluster
address 0.0.0.0
parents clusterserver1 clusterserver2
}
Define clustered service under virtual host.
define service{
host_name cluster
check_command servicename
}
Services will be checked under servers configured as parents if it is
available on any one of the node service will be ok.
Rgds,
Aravind M D

[Nagios-users] check_http and other response codes
On some of our apache servers, the normal response code is 401 (authentication required) rather than 200. I'd also like to use nagios to make sure the apache TRACE method stays disabled, with a response code of 405. Problem: check_http returns a warning if the response code is anything but 200. In the first case, both 200 and 401 are acceptable; in the latter case, I want 405 rather than 200. Is there a way to require or allow a different response code? I'm using check_http 1.4.15, as packaged with Debian 5.x. I googled, but didn't find clue. :( Thanks! - Morty -- All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.
