I'm developing an application that monitors assets (air conditioners, lamps, etc.) in a certain room and the floor plan of that room is illustrated in Nagios with assets in place.
I would like that after my application did a status check of these assets (check if they are turned on or off) these statuses were displayed in Nagios.
How to pass these parameters to Nagios? How do I get Nagios information from my application?
As far as I know, Nagios does not work this way. Home It may be that he is mistaken, but in my experience he acts as a client of the systems to be monitored. In other words, it does not become passive, waiting for data from the monitored locations. It has an active role and it does itself a survey of the status of the resources with a predefined frequency by script, being able to use different plugins and protocols (my experience was with HTTP).
In this case, your Java application would only be a mediator between Nagios and the monitored resources. It would have the following role:
I've done something similar.
In my case, my Java application received http requests from the Nagios system and returned the responses in pre-defined folders, so that Nagios could display them.
When a request was received by the application, it raised the status of the monitored resources and sent the response to Nagios. If you use this mechanism, there are 3 things to consider:
I hope I was clear enough and could have helped.
If you have questions, do not hesitate to write them.
