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

--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?

yes

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.
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.

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

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

Great! Let us know!
