API to POST metrics to AMS:
https://cwiki.apache.org/confluence/display/AMBARI/Metrics+Collector+API+Specification
You can query metadata API to check if metrics are written to the Collector
with this API:
http://:6188/ws/v1/timeline/metrics/metadata
Grafana UI's are driven by metadata API and no additional wiring up is required.
Ambari service dashboards however require more overhead of defining
metrics.json and widgets.json for your service. Here are the links for both:

Subject: custom metrics - tomcat
Hi,
I have a custom service in Ambari which contains tomcat server.
I would like to create metrics for the tomcat server like
number of requests coming in and memory usage.
Could someone point me to the right doc or steps.
Thanks,
Satya.
