Sysadmin

Hi all

I have been searching high and low but I think my search game is too weak. I am looking for a tool (similar to Uptime Kuma) that can monitor multiple systems via their own APIs, to centralise the status of these devices. Ex:

a) I have a sensor system that monitors a whole bunch of sensors across multiple locations. This system has an API that uses a secret key + api key for auth, and I can get the status of the sensor via the api. The idea is that the central dashboard shows the status, if offline, the control room personnel can log into the sensors system itself and determine root cause.

b) I also have a system to which a whole bunch of A/V equipment is connected, and via it's API I am able to view the status of multiple devices on the A/V equipment network. I want to also see on the status of these devices on my central monitoring system.

I don't care about doing root cause analysis via the central monitoring system, I just want the statuses which can action a person to check via the control system of that particular service.

All my searches come back with hits of systems that can monitor whether my APIs are up and running, but that is not what I want. Does anyone have any ideas? Preferably opensource, but definitely self-hosted/on-prem hosting. TIA
