Nagios Support Forum

Hello, we are using a python script as an event handler to send alerts to our ticketing system ServiceNow (Snow) as incidents. For example, when a host is down or unreachable it will create an incident via the Snow RestAPI containing the information (from macros) regarding the host down alert.

We are looking for a way for the python script to add the incident number (returned by Snow) in the Nagios XI alert or host object in one of the macro fields, so when the host becomes healthy again the event handler python script can read the recorded incident number and resolve it.

I've looked through the macro and API documentation and I cant seem to find a suitable way to do this or using a free variable. Has anyone achieved something like this if so any advice will be appreciated

Unfortunately, I can't come up with a quick way to do what you're trying to do right now. I'm thinking the ideal place to do this would be in Nagios Core, but its not a trivial task to write to host objects using externally available APIs, particularly if you're extending the data schema like this would be. Since there's a MySql/MariaDB server on your XI server, I'm wondering if it might be easier to add in a database there for what you're trying to do and have your python scripts work with that. A simple table with a host name and ServiceNow incident might be sufficient for that.
