Re: grafana influxdb nodered

you will need to start looking through log files in /var/log/ and see what things are saying.

Code: Select all

sudo service influxdb restart

Re: grafana influxdb nodered

Hmm looks like you will need to troubleshoot by looking through your logs and try and track down whats happening.

Is grafana-server running ?

have a look at your processes via top or ps i.e.

Code: Select all

ps -ax | grep grafana

Hi Dylan,

You need to make sure grafana-server service is up and running

Code: Select all

sudo service grafana-server start


to autostart on reboot:

Code: Select all

sudo chkconfig grafana-server on


then access grafana via http://xxx.xxx.xxx.xxx:3000/

Nice one, I think they are designed as a single fit and not meant to be removed once clipped together, more for assembling something
