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.
- 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.
- "Resource Metrics" is sorted by CPU_Utilization.
- "Shard Operation Metrics" is sorted by ShardEvents.
- "Workload" is sorted by HTTP_RequestDocs.
- "Shard Operation Metrics" is sorted by ShardEvents.
- "Circuit Breaker - Tripped Events / Estimated and Configured Limits" is sorted by CB_TrippedEvents.
- "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_*.
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 $NODENAME
is provided, the bar graphs will be aggregated metrics on cluster-level.
For more information, see the documentation.
Download the executables and preset JSON dashboard configs here.
Supported platforms: Linux, macOS
./perf-top-${PLATFORM} --dashboard $JSON --endpoint $ENDPOINT
Prerequisites:
node
(version >= v10.0 < v11.0)npm
- Clone/download from Github
- Run
./gradlew build
. This will run the following:npm install
- locally installs dependenciesnpm run build
- creates "perf-top-*" executables.
- For cleaning, run
./gradlew clean
which will run:npm run clean
- deletes locally installed dependencies and executables
To run PerfTop without (re)creating the executables every code change:
node ./bin.js --dashboard $JSON
