Tarantool Data Grid dashboard

Dashboard for Tarantool Data Grid ver. 2 application monitoring, based on grafonnet library.

About project

This dashboard is based on grafonnet library. Sources are available in project’s GitHub page.

Configuration

The dashboard is designed to work with TDG + Prometheus + Grafana cluster.

TDG configuration

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).

Dashboard

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
