Nagios Support Forum

It's usually the event handler script that has a logic issue in it, please attach it so that we can review it. Please add this to the very top (below the #!/bin/bash line): echo "`date +%s%3N` - Made it" >> /tmp/EVENT_HANDLER_OUTPUT.txt Then force a check or force it to execute and you sh...

In the service check, do you have the setting to enable the Event Handler? To check this, go to the Core Config Manager and open the service. Click on the Check Settings tab and verify that the service has the event handler configures and enabled. If you still have the issue, can you post the confi...

I changed the permissions for the Nagios user so they can run the script on the remote machine. I also changed the permissions so the user can connect to that machine via ssh. Retested the script for the Nagios XI server as the Nagios user and the script worked as expected. I then stopped the Cold F...

Thanks for the information.

It may be permissions related. I just tried to run the script as the Nagios user and it failed. I'll make some changes and update this once I can retry.

Thanks!!

Hi - I'm trying to create an event handler that runs a restart script when Nagios XI finds the web server in a CRITICAL state. I'm new to this so I found documentation and set up the handler based on what I read. When the HTTP service goes down the handler does not run. I can't seem to figure out wh...

No. I've discovered a problem with the configuration of the router that I'm addressing now to see if that helps.

Thanks -

That would be my guess as well. Verify that the setting in the router are correct for the NNA server's IP address and the port. Post the config so we can view the settings as well as the output from this command run on the NNA server. ps -ef --cols=300 Here's what I used to configure the router: co...

10 miliseconds wouldn't stop the capture. I am talking more like 5 to 10 minutes. Try stopping the firewall completely on the NNA server and see if it starts to receive the flow data. Still not seeing data. I'm thinking the problem is between my router and my firewall which sits in front of the NNA...

Can the router ping the NNA server and vice versa? If they are in different networks and the routing is not setup correctly, that could be the issue. One thing you can try is to run a tcpdump on the NNA server and see if the router's flow data is getting there. Run this on the NNA server, replace t...

We have an older Cisco 2811 router that I am trying to gather information on. The router has a public IP address and the NNA server has a private IP address. I set up NetFlow on the router and see that it is collecting data. I created a source through my NNA web interface assigning it a port number....
