In WildFly application servers there is the /metrics REST endpoint.
What is the best way to get the data provided from WildFly /metrics into splunk?
What we have found is the "REST API Modular Input" App (https://splunkbase.splunk.com/app/1546/), but this will cost 99$ per connection, and we have 200+ different WildFly Servers - comparing that to Prometheus + Grafana, which comes for free and has such an API "out of the box".
So it would be hard to justify this solution.
But as we already have a splunk environment we would like to keep that, so there must be a better solution for this, which costs less than this REST API Modular Input API". We have a Splunk forwarder on all WildFly servers, so it should be possible to grab the data somehow and push it to splunk.
We have also seen the "Splunk Add-on for Java Management Extensions" AddOn, but this seems like re-inventing the wheel, as the data necessary for monitoring is already provided in the /metrics endpoint. And opening a production server for remote JMX access seems odd - as JMX can do anything to that server, not just performance monitoring, which feels like a severe security breach, and JMX security and Beans change from release to release.
Who can help?
