-------------------------------------
Summary: Flow diagram for Metron Kafka topics
Key: METRON-1213
URL: https://issues.apache.org/jira/browse/METRON-1213
Project: Metron
Issue Type: New Feature
Affects Versions: 0.4.1
Environment: Management UI
Reporter: Jasper Knulst
Fix For: Next + 1
The insight that is really missing in Metron is an overview of Kafka topic
sizes and flow metrics (topic influx and outflux)
It is hard to answer questions like:
-Is the enrichments topic growing over time?
-What parser topics feed into enrichments, at what capacity?
-Is the enrichment topology keeping up with the projected influx from parsers?
-Same questions, but then for indexing topic
When the capacity of the chained topologies is not aligned bad thing can
happen, like a serious threat not reaching ES fast enough to react upon. Metron
can only be a realtime alerter if there is no congestion along the way.
This would take merging metrics from various Metron moving parts like Storm
API, kafka-offset-checker (state/snapshots and flow metrics units/sec)
