How to Monitor locally attached storage disks

[rkennedy]

Check your services and look for NSClient++ to see if it's running or not.

Additionally, is a firewall running on the Windows server?

[bsivavani]

NSClient++ service is running.

[lmiltchev]

Is a firewall running on the Windows server? Run the following commands on the Nagios XI server from the command line and show the output:

Code: Select all

ip addr
nmap <client ip> -p 5666

[bsivavani]

[root@irv-monprd001 libexec]# nmap 10.105.0.176 -p 5666
nmap: error while loading shared libraries: libsvn_client-1.so.0: cannot open shared object file: No such file or directory
[root@irv-monprd001 libexec]#


I have checked with network team and found there is no firewall between Nagios and client.

[rkennedy]

Is there one running on the exchange machine?

Can you run the following on your windows machine and post the output -

Code: Select all

netstat -na | find ":5666"

[bsivavani]

C:\Program Files\NSClient++>netstat -na | find ":5666"

It does not look like your NSClient is running. Can you navigate to your services and start the NSClient++ service?

[bsivavani]

NSClient service is running. It is listening on port 12489

I would like to know why it is not listening on 5666 and what are the steps I have to take for make it is listening.

Can you try this nsclient.ini instead of yours?

Code: Select all

# If you want to fill this file with all avalible options run the following command:

# If you want to activate a module and bring in all its options use:

I am able to connect client server with port 5666 from Nagios. Thanks for your help.

I am going to monitor mount volume and will reach you if I face any issues.
