PerfTop

The PerfTop CLI provides pre-configured dashboards for analyzing cluster, node, shard performance, and more. Use custom JSON templates to create the dashboards you need to diagnose your cluster performance.

Preset Dashboards

• All sorts are in decreasing order.
• Bar graphs show aggregated metrics on cluster-level unless stated otherwise.
• Line graphs generate random colors. If no data shows up, it's likely that the data is 0.

ClusterOverview

• "Resource Metrics" is sorted by CPU_Utilization.
• "Shard Operation Metrics" is sorted by ShardEvents.
• "Workload" is sorted by HTTP_RequestDocs.

ClusterNetworkMemoryAnalysis

• "Shard Operation Metrics" is sorted by ShardEvents.
• "Circuit Breaker - Tripped Events / Estimated and Configured Limits" is sorted by CB_TrippedEvents.

ClusterThreadAnalysis

• "Thread Pool - Queue Size and Rejected Requests" is sorted by ThreadPool_RejectedReqs.
• "Thread - Blocked Time" is sorted by Thread_Blocked_Time.
• "Page Faults" is sorted by Paging_MajfltRate.
• All "Context Switch" tables are sorted by Sched_*.

NodeAnalysis

This dashboard supports --nodename $NODENAME command-line argument for displaying metric data for ONLY the node that starts with $NODENAME. If not provided, this dashboard will include all nodes. Users can also define different node names for each type of graphs from the JSON dashboard config.

• "Shard Operation Metrics" is sorted by ShardEvents.
• "Shard Request Cache Miss" is sorted by Cache_Request_Miss.
• "Thread Pool - Queue Size and Rejected Requests" is sorted by ThreadPool_RejectedReqs.
• "Heap Usage" is sorted by Heap_Used.
• If no --nodename $NODENAME is provided, the bar graphs will be aggregated metrics on cluster-level.

Installation

Install with npm:

npm install -g @aws/opendistro-for-elasticsearch-perftop

Excutables:

Download the executables and preset JSON dashboard configs here.

Supported platforms: Linux, macOS

Usage

npm:

opendistro-perf-top --dashboard NodeAnalysis

Excutables:

./opendistro-perf-top-${PLATFORM} --dashboard $JSON --endpoint $ENDPOINT

Build

Prerequisites:

• node (version >= v10.0 < v11.0)
• npm

1. Clone/download from Github
2. Run ./gradlew build -Dbuild.linux={true/false} -Dbuild.macos={true/false}. This will run the following:
   1. npm install - locally installs dependencies
   2. npm run build-{linux/macos} - creates "opendistro-perf-top-{linux/macos}" executables.
3. For cleaning, run ./gradlew clean which will run:
   1. npm run clean - deletes locally installed dependencies and executables

To run PerfTop without (re)creating the executables every code change:

node ./lib/bin.js --dashboard $JSON
