```
cp -r <tdengine-extrach-dir>/connector/grafana/tdengine /var/lib/grafana/plugins/
sudo service grafana-server restart
```
### Query API
Example request
``` javascript
[{
"refId": "A",
"alias": "taosd-memory",
"sql": "select avg(mem_taosd) from sys.dn where ts > now-5m and ts < now interval(500a)"
},
{
"refId": "B",
"alias": "system-memory",
"sql": "select avg(mem_system) from sys.dn where ts > now-5m and ts < now interval(500a)"
}]
```
Example response
``` javascript
[{
"datapoints": [
[206.488281, 1538137825000],
