Re: Nagios xi performance

Just to verify, do the slave machines have the following plugin?

/usr/local/nagios/libexec/check_wmi_plus.pl

If so, what are the permissions on it?

they do, I did test running the check_wmi_plus script from the command line of the slave machine and it did work. I am also getting failures on my ping tests

The slave machines are the same xi vm appliances that I downloaded and am using for the dnx master (2011R1.9)

I seem to recall when I installed the DNX server that it prompted for a password for the 'nagios' account on the slaves, that script indicated the password by default was 'welcome'. I couldn't find the default pw in the documenation for those machines so I did reset them to use welcome.

It still could be a permissions issue.

On the slave machine can you run

Re: Nagios xi performance

This all looks correct.

I think you are going to need to look in a couple directions.

First
Verify that the configuration files have correct information:
Server: /usr/local/nagios/etc/dnxServer.cfg
Client: /usr/local/nagios/etc/dnxClient.cfg

Also make sure from the client you can reach the server's udp port and you don't have a firewall or iptables blocking you.

Re: Nagios xi performance

Post by paul.jobb »

I was able to replay a nagiosvm on my desktop and dnxClient seems to start and remain running there, I compared the services and iptables between both and they appear to be identical. When running dnxClient on the affected machine it seems to start and then stop immediately, are there any command line options for /usr/local/nagios/sbin/dnxClient that I might be able to enable for logging as to why it is shutting down?

it doesn't appear that dnxClient is running on my workstation VM anymore, though I could of swore it was yesterday when I left it, so disregard what I said previously.

It appears that dnxclient doesn't want to run on Centos version 6. The earlier version of the xi appliance I had was centos 5.6, which it does start on. I tested on a minimal install of Centos 5.7 and 6.2, dnxclient does run on 5.7 but not 6.2.

Just an update on this, for whoever is interested, I switched to using mod_gearman instead of DNX. It seems to be more stable and effective for what I need, I was able to distribute pretty well all of the load to my workers/slaves , The install isn't as straight forward as DNX but worth it.
