Nagios Support Forum

Hi,

We are trying to monitor hardware health of ESXi server using below plugin

https://exchange.nagios.org/directory/P ... th/details

We are getting the below error while running the command
[root@s930l3301 tmp]# ./check_ilo2_health.pl -H s930e0130.rwe.com -u testusr -p testusr123 -t 60
ILO2_HEALTH UNKNOWN - ERROR: No parseable output.
[root@s930l3301 tmp]#

Kindly advice.

take a look at an old thread that runs through the same issue - https://support.nagios.com/forum/viewto ... =7&t=10878

I checked the old thread.

We have 777 permissions to plugin
[nagios@s930l3301 tmp]$ ll /usr/local/nagios/libexec/check_ilo2_health.pl
-rwxrwxrwx 1 apache nagios 32162 Aug 8 18:38 /usr/local/nagios/libexec/check_ilo2_health.pl
[nagios@s930l3301 tmp]$

Tried with both nagios and root users, but still we are seeing the same issue

[nagios@s930l3301 tmp]$ /usr/local/nagios/libexec/check_ilo2_health.pl -H s930e0130.rwe.com -u testusr -p testusr123 -t 60
ILO2_HEALTH UNKNOWN - ERROR: No parseable output.
[nagios@s930l3301 tmp]$

If the plugin cannot connect to the ILO module, it will print out that error. It does look like the plugin runs but cannot connect to the ILO module.
Can you provide any information on the settings for the ILO module?
Is it setup to use SSL and if it enabled, what mode is it set to?
Is is an ILO3 or an ILO4 device?

Can you run the plugin in verbose mode to see what errors are generated. Run the following to do that.

Please find requested information

Can you provide any information on the settings for the ILO module?Kindly let me know what settings require.

Is it setup to use SSL and if it enabled, what mode is it set to?
Kindly let me know how to check mode of SSL.

Is is an ILO3 or an ILO4 device?
We are using ILO4.

Plugin output in verbose mode
[root@s930l3301 tmp]# /usr/local/nagios/libexec/check_ilo2_health.pl -H s930e0130.rwe.com -u testusr -p testusr123 -t 60 -v

We do not have access to any hardware that supports the ILO module so you would have to contact the manufacturer for instructions for setting it up.

If your server uses an ilo3 or ilo4, using the plugin without telling it you have a v3 or 4 will not work. Here is what is parsed out for my ilo3 and ilo4 interfaces:
Notice the -3 -g -d. the -3 tells the plugin this is an ilo3/4 device, while -g shows increased information and -d adds perfdata. If you don't need those, just try manually running the plugin with a -3.
You can play around with the options by invoking the plugin on the command line with the help flag:

Thanks @gwakem for the help on this.

Thank you for the response.

We are using ilo4, as suggested tried with below command

[root@s930l3301 tmp]# /usr/local/nagios/libexec/check_ilo2_health.pl -H s930e0130.rwe.com -u testusr -p testusr123 -t 30 -3 -g -d -v

Still receiving the same error.

Can you access the ILO web interface?
