Cheshire Cat Computing

Thanks for the info Steve, the web console is enabled and working, and now I'm passing the user/pass in CLI the 'server status' and 'datastores' are both returning valid data.

Is there anything else I can query on standalone ESX/ESXi servers, other than 'disk' and 'status'?

I'm going to add a VC to the system in the next few days to compare the difference, but several of the systems we want to monitor are standalone (unfortunately).

What is the correct syntax to pass the user/pass as part of the config file please?

Finally, when running in Nagios, I'm still getting (Return code of 127 is out of bounds - plugin may be missing). Perl is installed on the server, but wasn't present when Nagios was compiled. Do you think I need to recompile either/both Nagios and Nagios-plugins with Perl modules enabled for this to work correctly?

You wont need to recompile Nagios - in fact, this plugin does not work with the Nagios EPN and if you do have the EPN enabled, it has to be specifically disabled for this script (see the comments at tyhe beginning of the script)

If you run the plugin with the -h option it gives all the available options, plus the names of the environment variables you can set in a separate configuration file which you specify with --confg

eg, in file vmconfig:
VI_SERVER=myesxserver
VI_USERNAME=myuser
VI_PASSWORD=foobarbaz

Then you can use something like:
check_vmware --config=vmconfig --mode=nagios --report=cpu --guest=guestname

OK, thanks. I've tried configuring that way, but I'm still getting (Return code of 255 is out of bounds) - hey, at least the error has changed! lol


Here is my config:

commands.cfg

--snip---
# Check VMware ESX Host Status
define command{
command_name check_vmware_status
command_line /usr/local/nagios/libexec/check_vmware --config=vmconfig --mode-nagios --report=status
}
---/snip---

---esx.cfg---(called by nagios.cfg)
define hostgroup{
hostgroup_name esx-servers ; The name of the hostgroup
alias ESX Servers ; Long name of the group
members esx
}

define host {
use linux-server
host_name esx
alias ESX Server
address 10.0.0.2
}

#Check ESX Host Status
define service {
use generic-service
hostgroup esx-servers
service_description VMware: Status
check_command check_vmware_status
normal_check_interval 60
retry_check_interval 15
max_check_attempts 2
}
---/esx.cfg---

---vmconfig---
VI_SERVER=10.0.0.2
VI_USERNAME=root
VI_PASSWORD=password
---/vmconfig---


Any idea what has gone wrong? It's still OK from the shell.

Try running the command from the shell *as the Nagios user* -- sometimes, you may be testing as root but running in Nagios as the nagios user. There might be a permissions issue.

Also, make sure you are not using the EPN. If you have enabled this then disable it by adding the line

as the second line in the file if it is not already there.

Hrmmm.....

It worked fine and returned valid data when logged on as the Nagios user. ???

Where should I include the -epn switch in the config?

It goes at the top of the check_vmware script; it makes sure that the script is NOT run under the embedded perl interpreter, as it will not work with this. The Vmware library is not able to run in this sort of environment.

OK, thanks - I can't find the correct section of the script to add that line.

Any ideas why it runs from the command line, but not the Nagios web interface? Is it just the -epn switch I need to add to the script?

Hi Guys,

I think I'm going to try a different tack - I'm going to check this script using NSCA - any tips on config/setup?

Hello All,

I learned few new thing from the threads. I still have few queries :
What type of custom reporting can you do with this? What type of data rollup happens?

Do you have any screen shots of ESX reports?

Thanks!

This is a plugin for MRTG and Nagios, so reporting is down to the abilities of those packages. Take a look in http://www.nagios.org and http://www.mrtg.org -- the MRTG can display via the Routers2 frontend which is fairly configurable http://www.steveshipway.org/cgi-bin/routers2.pl
