VMware wizard

[emartine]

I followed the documentation for instaling the vmware monitoring wizard here and I ran into an issue:

./vmware-install.pl EULA_AGREED=yes
A previous installation of vSphere CLI has been detected.

Is this really a permissions problem? I ran this as root.

Is this a 64- or 32-bit system?

Some users reported a similar/same error here:
https://communities.vmware.com/thread/589430

Run the following commands and show the output:

Code: Select all

uname -a
cat /etc/*release

[emartine]

64bit and RHEL 6.9
VMware-vSphere-Perl-SDK-6.7.0-8156551.x86_64.tar.gz

[emartine]

Looks like it installed properly after I created the directory

Socket6-0.23-rhel6

under the re-extracted package:

/tmp/vmware-vsphere-cli-distrib/lib/5.10/Socket6-0.23-rhel6

[lmiltchev]

Ah, this is what the SupreetK user suggested. I am glad your issue has been resolved! Let us know if you have any further questions. Thank you!

This wizard seem to be more informational and doesn't provide thresholds.
Is that correct? Is this informational only?

[lmiltchev]

I believe adding the thresholds to the wizard would be very difficult and it would not make much sense. That's why they were left out. Many of the vmware checks return more than one metric. Sometimes, even the units of measurement are different. So, unless you specify a metric, adding warning/critical thresholds don't make any sense.

Example:

Code: Select all

/usr/local/nagios/libexec/check_vmware_api.pl -H "x.x.x.x" -f "/usr/local/nagiosxi/etc/components/vmware/VMWARE_HOST_auth.txt" -l "CPU" -w 10% -c 20%
CHECK_VMWARE_API.PL OK - cpu usage=10375.00 MHz (25.43%) | cpu_usagemhz=10375.00;10;20 cpu_usage=25.43%;10;20

Using thresholds here doesn't make sense, and it doesn't work. One metric (usage) is measured in percentage, but the other one (usagemhz) is measured in MHz... You could use thresholds if you used a "sub-command" (-s).

Code: Select all

/usr/local/nagios/libexec/check_vmware_api.pl -H "x.x.x.x" -f "/usr/local/nagiosxi/etc/components/vmware/VMWARE_HOST_auth.txt" -l "CPU" -s usage -w 10% -c 20%
CHECK_VMWARE_API.PL CRITICAL - cpu usage=25.43 % | cpu_usage=25.43%;10;20

Hope this makes sense.

I can see that there is a way to monitor the datastore vmfs. Is there a way to monitor the host local disk?

[lmiltchev]

I don't see any such option built in the plugin. You may need to use some custom plugin/script for that. If you want to monitor a disk on a specific VM, you could just install an agent, e.g. NCPA. If however you need to monitor a disk on the ESX server itself, then this won't work. You would have to setup some custom script, that sends passive check results to Nagios XI.
