Hi,
I am looking for an advice on the best approach for the following.
We currently have a linux server producing a custom metric for an internal application. This metric is currently simply logged in a file on the server.
I was wondering if I could not use centreon for basic monitoring of this metric. T​​​​​o have alerting and easy historic access with a graph.
I suppose there is different possibility for that. Maybe transform this metric into a custom snmp information that could be recovered by centreon for exemple. Or via the nrpe plugin. I was wondering what you would recommend to avoid as much customisation as possible and keep it as simple as possible.
The real solution is to have observability of the app with something like open telemetry standard but this is too early for now. 
Regards,

The question is are you already using Centreon ? I suppose so else why ask that question here.

So the future proof version of observability with Centreon is to be done with the CMA (Centreon Module Agent) Introduction to CMA | Centreon Documentation it is using opentelemetry in passive mode to push data to Centreon, but you may as well use it to push data to any OTEL database.

 

After that you can create your very own custom plugin to be executed by the agent on your machines Using custom plugins with CMA | Centreon Documentation this is (from what i know) using the standard for nagios plugins developements with the performance data used to create graphs. For example on how they develop custom plugins you can take a look at the OSS plugins project they have at centreon/centreon-plugins: Collection of standard plugins to discover and gather cloud-to-edge metrics and status across your whole IT infrastructure.

 

Hope this all helps

Hi,

Apologies it was so obvious to me I forget to precise it. I do use centreon to monitor the infrastructure.
I use it with default plugin setups so without doing anything fancy.

From your answer there is some custom dev involved if we want to do file content monitoring. There is no magic feature I was not aware of 😊

Thanks for your quick answer.
