Does the NSClient have to be installed on VM hosts in order for it to be monitored?
Is there an NSClient for linux machines?

NSClient is by far not the only way to monitor objects, you have many ways of doing so. You could use SNMP gets / traps, NCPA, NSCA, NRDP/S, WMI, check_nt, etc. It all depends on what you want to use for each host. The equivalent to NSClient++ on the linux/unix end would be either the NCPA agent, or NRPE agent.

Thank you!

Our VMware engineer is very concerned about going through with installing the NRPE rpm on the VM ESX as the root user. Can you assure that this will not stop any services or bring down the ESX and there will be no down time because 80% of our servers reside on this ESX?

The NagiosXi Server says that there is no SDK installed to Nagios for the guest vm, but when I went through the process to install the SDK to the Nagios Server, this is the result that I get:

[root@localhost vmware-vsphere-cli-distrib]# cd /tmp
[root@localhost tmp]# tar xzf VMware-vSphere-SDK-for-Perl-5.5.0-1384587.x86_64.taz.gz

Shouldn't this be (tar.gz instead of taz.gz):

I apologize, that's what I meant.

Then just to be sure x/vmware-install.pl would just be ./vmware-install.pl. Did you also fix that up?

Yes

Since I have not seen it listed, have you been following our vmware install doc? Also just to inform you since no one else did, there is no way presently to install nrpe\nsca on an esx host, the vmware sdk is needed. So, with all that, are you getting errors with the vmware install after referencing the correct install files?

Yes, I did follow that document. I received an error while trying to install command so when I try configure an guest os vm, it is saying that the SDK isn't installed.
