Tarantool Data Grid dashboard
Dashboard for Tarantool Data Grid ver. 2 application monitoring, based on grafonnet library.
The dashboard is designed to work with TDG + Prometheus + Grafana cluster.
The dashboard is designed to work with Tarantool Data Grid (ver. 2) cluster.
TDG must be configured to have a prometheus metrics endpoint for Prometheus (refer to cartridge.roles.metrics role page for instructions).
Metrics used in dashboard are based on Tarantool metrics module and TDG metrics. Time series are grouped by alias parameter, so you can use this dashboard to monitor a cluster of Tarantool instances.
Dashboard contains the following sections:
- Cluster overview
- Tarantool network activity
- Tarantool memtx allocation overview
- Tarantool vinyl statistics
- Tarantool CPU statistics
- Tarantool runtime overview
- Tarantool LuaJit statistics
- Tarantool operations statistics
- TDG Kafka common statistics
- TDG Kafka brokers statistics
- TDG Kafka topics statistics
- TDG Kafka consumer statistics
- TDG Kafka producer statistics
- TDG expirationd statistics
- TDG tuples statistics
- TDG file connectors statistics
- TDG GraphQL requests
- TDG IProto requests
- TDG REST API requests
- TDG tasks statistics
Contains several cluster overview panels, providing some aggregated info on cluster instances health, overall load and memory stats. Also contains panels on Cartridge issues count, replication lag and status, read only status and instances clock delta.
Tarantool network activity
Overview of instances network activity. Displays input and output data load, as well as network connections, detailed requests stats and memory consumption.
Tarantool memtx allocation overview
Overview of Tarantool memtx memory allocation (tuples and indexes). Contains short instruction on memory allocation monitoring. You can read more about slab here.
Tarantool vinyl statistics
Overview of Tarantool vinyl memory and disk allocation, vinyl scheduler process and transaction statistics. You can read more about vinyl engine here.
Tarantool CPU statistics
Contains CPU process time statistics for each instance and separate thread load.
Tarantool runtime overview
Metrics related to runtime. Contains Lua and transaction memory panels, fiber statistics panels and event loop panel.
Tarantool LuaJit statistics
Detailed Lua runtime overview. Contains panels about objects allocation and garbage collect, memory consumption and LuaJit traces info.
Tarantool operations statistics
Overview of operations on Tarantool spaces (select, update, etc.) aggregated over all Tarantool spaces, as well as other operations activity (eval, call, auth, errors and SQL calls).
