We're using ELK (Elasticsearch, Logstash Kibana) to monitor our applications. There's an option to use APMs to feed application info into elasticsearch however I've not yet found any clear guidance on installing an APM alongside the Atlassian apps. The Oracle tomcat APM agent documentation is quite dense and I'm not convinced it's actually the Thing We Need. I've found info on pms that are specific to other monitoring apps (new relic for instance) but I'd imagine they only work with that monitoring tool.
Does anyone have experience with this and can make suggestions?
