NAGIOS CORE: HOW TO MONITOR HOST ESX 5.5

[stecino]

Hello,

I am having a problem with monitoring the host, I get host unknown error

on the VMA server I run the following command which executes fine

vi-admin@pbur2vma1:~> ./box293_check_vmware.pl --check Datastore_Usage --server 10.xx.x.xxx --name "SBUR-DS01" --username xxxx
OK: Datastore 'SBUR-DS01' {Free Space: 17,281.5 GB} {Used Space: 13,894.5 GB} {Capacity: 31,176 GB}|'Free Space'=17281.5GB 'Used Space'=13894.5GB 'Capacity'=31176GB [Datastore_Usage]

This is the problem

vi-admin@pbur2vma1:~> ./box293_check_vmware.pl --check Datastore_Performance --server 10.xx.x.xxx --host 10.xx.x.yyy --name "SBUR-DS01" --username xxxx
UNKNOWN: Host '10.xx.x.yyy' not found [Datastore_Performance]

Thanks in advance

From the manual, here, there is an example:

Example 1:
box293_check_vmware.pl --check Datastore_Performance --server 192.168.1.211 --host
192.168.1.210 --name "ESXi 5.1"
Output for Example 1:
OK: Datastore 'ESXi 5.1' {Rate (Read:32 kBps / 21%)(Write:122 kBps / 79%)} {Number of
(Reads:20) (Writes:109)} {Latency (Read:0 ms)(Write:1 ms)}|'Read Rate'=32kBps 'Write
Rate'=122kBps 'Number of Reads'=20 'Number of Writes'=109 'Read Latency'=0ms 'Write
Latency'=1ms

Are you sure that the --host is

--host (the host that the datastore is connected to)

Can you verify the IP is correct? It may be different from the server.

Yes, in VWare Client, I select the datastore, and selected the hosts tab to list all the ESX hosts that are connected to that datastore

The --host value needs to match the name of the host as it appears in the vSphere client.

For example, if your host appears as esx55_01.domain.local then you must type:

--host esx55_01.domain.local

For example, if your host appears as esx55_01.domain.local then you must type:

--host esx55_01.domain.local

So here is what I did:

./credstore_admin.pl add -server esxi316.xxxxx.com -username nagios -password xxxxxxx

./box293_check_vmware.pl --check Datastore_Performance --server 10.xx.x.xxx --host esxi316.xxxxxx.com --name "SBUR-DS01" --username nagios

Do you have a vcenter server?

[stecino]

Do you have a vcenter server?

yes

[Box293]

OK so you don't need to add the credentials for the ESXi server as vCenter handles all this.

Can you run the command again on the vMA but this time add the --debug argument at the end.

Code: Select all

./box293_check_vmware.pl --check Datastore_Performance --server 10.xx.x.xxx --host esxi316.xxxxxx.com --name "SBUR-DS01" --username nagios --debug

This will create the file /home/vi-admin/box293_check_vmware_debug_log.txt
Please PM me that file and I'll investigate some more.

Thanks alot, I will run it shortly and send you the log
