I have created Nagios virtual Instance on Amazon Ec2 Cloud enviorment according to steps given below URL:

https://assets.nagios.com/downloads/nag ... -Cloud.pdf

After that I have Installed NSClient++ on windows Server the one which I have to monitor using Nagios EC2 Instance but its showing Socket Time out error for all monitored services in NagiosXI dashboard[ Note: Firewall turned off on windows server so there is no chance to block ports]

In the Amazon management interface you need to open the network ports for it to work.

Following two ports already opened on AWS but still its giving socket timeout error:

Custom TCP Rule TCP 12489 0.0.0.0/0
Custom TCP Rule TCP 5666 0.0.0.0/0

Following two ports already opened on AWS but still its giving socket timeout error:

Custom TCP Rule TCP 12489 0.0.0.0/0
Custom TCP Rule TCP 5666 0.0.0.0/0

Is this on the windows server in the EC2 instance?

Can you provide your nsclient.ini file from the Windows server.

Hi,

Just to give more info, I have open TCP ports on Nagios EC2 Instance to communicate with our local windows server(Note:This windows server is running locally in my company and only Nagios Instance running on Amazon AWS)

Also please find attached nsclient.ini file from the Windows server.

I don't see any listening ports in your config, what is the output of netstat -an | findstr "5666" on the windows machine?

Also - have you enabled the rules through Windows firewall?

[rahul5028]

Here is the output of netstat -an | findstr "5666"(Refer attached screenshot).

Also my windows firewall turned-off , Do we still require to enable the rule through windows firewall.

Can you also run netstat -an | findstr "12489"?

Are your services attempting to use check_nrpe or check_nt?

[rahul5028]

Here is the output of netstat -an | findstr "12489".


I'm not sure which one(check_nrpe,check_nt) my service attempting to use, Can you give some steps to check this?

Looks good regarding listening, I don't think your nsclient configuration is an issue.

To figure out what service you're using navigate to Configure -> Core Config Manager -> Click 'Services' on the left side, and search for the service in question.

You should see a page similar to this -

One more thing to check, from the nagios machine, on the CLI can you run nmap windowsip? (replace windowsip with the IP for the windows machine we're trying to check)
