Epic Name:Ambari Metrics System
Ambari Metrics System
- Ability to collect metrics from Hadoop and other Stack services
- Ability to retain metrics at a high precision for a configurable time period (say 5 days)
- Ability to automatically purge metrics after retention period
- At collection time, provide clear integration point for external system (such as TSDB)
- At purge time, provide clear integration point for metrics retention by external system
- Should provide default options for external metrics retention (say “HDFS”)
- Provide tools / utilities for analyzing metrics in retention system (say “Hive schema, Pig scripts, etc” that can be used with the default retention store “HDFS”)
System Requirements
- Must be portable and platform independent
- Must not conflict with any existing metrics system (such as Ganglia)
- Must not conflict with existing SNMP infra
- Must not run as root
- Must have HA story (no SPOF)
Usage
- Ability to obtain metrics from Ambari REST API (point in time and temporal)
- Ability to view metric graphs in Ambari Web (currently, fixed)
- Ability to configure custom metric graphs in Ambari Web (currently, we have metric graphs “fixed” into the UI)
- Need to improve metric graph “navigation” in Ambari Web (currently, metric graphs do not allow navigation at arbitrary timeframes, but only at ganglia aggregation intervals)
- Ability to “view cluster” at point in time (i.e. see all metrics at that point)
- Ability to define metrics (and how + where to obtain) in Stack Definitions
