title: 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
|
||
|
||
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
|
||
```
|
||
|
||
Prepare：
|
||
|
||
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`
|
||
|
||
```bash
|
||
sudo ./TDinsight.sh -a http://localhost:6041 -u root -p taosdata -E <notifier uid>
|
||
```
|
||
|
||
Launch `TDinsight.sh` with the command above and restart Grafana, then open Dashboard `http://localhost:3000/d/tdinsight`.
|
||
|
||
For more use cases and restrictions please refer to [TDinsight](/reference/tdinsight/).
