TDengine Monitoring

After TDengine is started, it automatically writes monitoring data including CPU, memory and disk usage, bandwidth, number of requests, disk I/O speed, slow queries, into a designated database at a predefined interval through taosKeeper. Additionally, some important system operations, like logon, create user, drop database, and alerts and warnings generated in TDengine are written into the log database too. A system operator can view the data in log database from TDengine CLI or from a web console.

The collection of the monitoring information is enabled by default, but can be disabled by parameter monitor in the configuration file.


TDinsight is a complete solution which uses the monitoring database log mentioned previously, and Grafana, to monitor a TDengine cluster.

Please refer to TDinsight Grafana Dashboard to learn more details about using TDinsight to monitor TDengine.

A script is provided to deploy TDinsight automatically.

Download with the below command:

chmod +x


  1. TDengine Server

    • The URL of REST service:for example http://localhost:6041 if TDengine is deployed locally
    • User name and password
  2. Grafana Alert Notification

You can use below command to setup Grafana alert notification.

An existing Grafana Notification Channel can be specified with parameter -E, the notifier uid of the channel can be obtained by curl -u admin:admin localhost:3000/api/alert-notifications |jq

sudo ./ -a http://localhost:6041 -u root -p taosdata -E <notifier uid>

Launch with the command above and restart Grafana, then open Dashboard http://localhost:3000/d/tdinsight.
