Hi nagios team ,

Nagios Reactor must be installed after Nagios COre or it can be installed alone ?

thanks

We recommend that you install Nagios Reactor on a separate server, that being said, we have seen people install it on the same server. Make sure to take snapshots/backups before trying it.

Nagios Reactor = Nagios Core + fix problems ?

I am not sure what you mean by that. Can you elaborate?

i mean nagios reactor can do what nagios core does and more ?

No, Reactor is in addition to Core/XI, Reactor is the automation engine and doesn't have the Core/XI functionality.

Are you asking how to add a web link in the interfaces or are you asking how to have reactor take action?

You are going to be using event handlers for working with reactor, the thread below gives some good information on the basics (it's in relation to XI but event handlers are in both and it's relevant).

http://support.nagios.com/forum/viewtop ... 30&t=30808

More specifically:

Correct, event handlers in XI/[Core] are not the same as in Reactor. Reactor doesn't really have "event handlers" in the sense that XI does, they just have Event Chains which can do certain things. Similar concept though.

However, in order to manually run a chain in Reactor, go to Event Chains, then click the name of the chain you want to run. Click "More Info" and you will see some additional information including a URL to run the chain directly via a HTTP GET or POST request. It will look similar to the following:

Code: Select all

http://192.168.1.100/nagiosreactor/index.php/api/eventchain/1/run?api_key=dd1720efe6750330f416f31610e3464b

And:

If you click the "POST" method on that page I sent you to it will give example usage:

Code: Select all

curl --data 'api_key=dd1780e0e6750330f416f81610e3664b' http://192.168.1.100/nagiosreactor/index.php/api/eventchain/1/run
