and metrics to monitor instance task
nwangtw opened a new pull request #3127: Add CumulativeCountMetric and metrics to monitor instance task
URL: https://github.com/apache/incubator-heron/pull/3127
An internal user reported that in some edge case, spout instance could stop for a while. So far it is hard to tell the root cause but it seems like the spout task is not triggered. In this PR:
- added a new cumulative count metric.
- refactored SpoutMetrics and BoltMetrics.
- added metrics to monitor spout and bolt task runs and metric collector run.
Tested:
1. Build package and install cli.
2. Start an example topology: ~/.heron/bin/heron submit local ~/.heron/examples/heron-streamlet-examples.jar org.apache.heron.examples.streamlet.WindowedWordCountTopology WindowedWordCountTopology
3. Open metrics log file and verify: vim ~/.herondata/topologies/local/nwang/WindowedWordCountTopology/metrics.json.metricsmgr-1.1
4. Stop topology: ~/.heron/bin/heron kill local WindowedWordCountTopology
