Support Needed - CCM

[ancovington]

I have a question...some people here are questioning whether or not Nagios is the right product for our VM environment. We know that V-Op and Solarwinds go in depth with monitoring entire VM environment. Does Nagios do the same? Does Nagios monitor vcenter? There is an option for monitoring the host and guest vm, but can Vcenter be monitored in a way that it will let you know what is going on in the entire environment? (i.e. when there is an issue with C drive, will it tell you what is taking up the C drive space or CPU capacity if needed?)

Yes yes and yes, if you have not already I'd look into Configure > Monitoring Wizard > VMware and also:

http://exchange.nagios.org/directory/Ad ... rd/details

In addition to those, if you are able to install NRPE or configure NRDS.. etc for passive checks you can monitor the server's physical hardware that is not listed in those wizards as you also mentioned above.

I installed the ESX wizard, but it only says 3.0 or vsphere 4.x. I know the one I installed was for 5. Is this not supported?

[sreinhardt]

Any of the vmware perl sdk installations are just fine for the nagios vmware checks. They are all backwards compatible with older esx and vsphere versions, more than anything we should probably update that line.

[ancovington]

So just to verify, although we have vcenter server 5.1 we can use the monitoring wizard on NagiosXi that says monitor a wmware esx 3.x/vsphere 4.x host or vcenter server?

[sreinhardt]

Yes you can, it works perfectly fine. I do it at home, and we do it here at the office!

[ancovington]

We have added our vcenter successfully. Thank you.

We are now getting this error. How can this be resolved? Does it have to be deleted and re-added?

[slansing]

It looks like it is not resolving to your vcenter web address correctly, were you sure to change this from the default?

[ancovington]

How can this be changed because I do not see this as an option when I try to reconfigure.

[sreinhardt]

Before we go about changing that hostname, can you do an nslookup and verify that it cannot resolve dns for the vcenter server. If it is able to resolve the hostname, does it resolve to the correct IP? Be sure to change the host in this command, to what it is actually returning from the check.

Code: Select all

nslookup [yourvcenterserver.yourdomain.local]
