Troubleshooting
If Grafana contains no data, use the following troubleshooting tips:
Verify that the StackLight Collector is running properly by following the troubleshooting instructions in the StackLight Collector Fuel plugin documentation.
Verify that the nodes are able to connect to the InfluxDB cluster through the VIP address (See the Verify InfluxDB section for instructions on how to get the InfluxDB cluster VIP address) on port 8086:
root@node-2:~# curl -I http://<VIP>:8086/ping
The server should return a 204 HTTP status:
HTTP/1.1 204 No Content Request-Id: cdc3c545-d19d-11e5-b457-000000000000 X-Influxdb-Version: 0.10.0 Date: Fri, 12 Feb 2016 15:32:19 GMT
Verify that InfluxDB cluster VIP address is up and running:
root@node-1:~# crm resource status vip__influxdb resource vip__influxdb is running on: node-1.test.domain.local
Verify that the InfluxDB service is running on all nodes of the cluster:
root@node-1:~# service influxdb status influxdb Process is running [ OK ]
If the InfluxDB service is not running, restart it:
root@node-1:~# service influxdb start Starting the process influxdb [ OK ] influxdb process was started [ OK ]
Verify that the Grafana server is running:
root@node-1:~# service grafana-server status * grafana is running
If the Grafana server is not running, restart it:
root@node-1:~# service grafana-server start * Starting Grafana Server
If none of the above solves the issue, look for errors in the following log files:
- InfluxDB --
/var/log/influxdb/influxdb.log
- Grafana --
/var/log/grafana/grafana.log
- InfluxDB --
