--- title: TDengine Monitoring description: This document describes how to monitor your TDengine cluster. --- 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 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](../../reference/tdinsight) to learn more details about using TDinsight to monitor TDengine. A script `TDinsight.sh` is provided to deploy TDinsight automatically. Download `TDinsight.sh` with the below command: ```bash wget https://github.com/taosdata/grafanaplugin/raw/master/dashboards/TDinsight.sh chmod +x TDinsight.sh ``` Prepareļ¼š 1. TDengine Server - The URL of REST serviceļ¼šfor 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` ```bash sudo ./TDinsight.sh -a http://localhost:6041 -u root -p taosdata -E ``` Launch `TDinsight.sh` with the command above and restart Grafana, then open Dashboard `http://localhost:3000/d/tdinsight`.
