Type Members

1. class ProcessorAggregator extends MetricsAggregator

   

   Does aggregation on metrics after grouping by these three attributes:

   Does aggregation on metrics after grouping by these three attributes:

   1. processorId 2. time section(represented as a index integer) 3. metricName(like sendThroughput)

   It assumes that for each org.apache.gearpump.cluster.MasterToClient.HistoryMetricsItem, the name follow the format app(appId).processor(processorId).task(taskId).(metricName)

   It parses the name to get processorId and metricName. If the parsing fails, then current org.apache.gearpump.cluster.MasterToClient.HistoryMetricsItem will be skipped.

   NOTE: this class is optimized for performance.

2. class TaskFilterAggregator extends MetricsAggregator

   

   Filters the latest metrics data by specifying a processor Id range, and taskId range.
