Influxdb2 - Timer Expired, problem?

Icinga Web
1

I’m a new user of Incinga and trying to get the InfluxDB2 integration working.

Logging seems to indicate it is doing something.

and the InfluxDB logging seems to show it is connecting OK.

But nothing appears to be happening in the UI and the logs seem to indicate it is simply timing out?

I’ve gone through the docs but can’t see anyway to make the graphs appear in the UI - maybe i’m expecting them to appear but there is a step missing which isn’t obvious.

Thanks for any help received in advance.

To actually visualise the data you have to use Grafana, the is an integration for Icinga Web 2 to show the graphs in there.

Regarding the timeout I have no idea, maybe a firewall in the way, typo in the address of Influxdb or something like that?

Ah thank you.

No firewall, all on localhost.

Will see how I get on debugging further.

It looks like data is moving along, at least, I can see when I am using the Grafana query tool.

Using the templates, these don’t appear to support InfluxDB2. Have found on partially working for basic services in the Grafana public dashboard library.

It would be nice to see some docs updated for the graphing as the one(s) on the site reference quite out of date information, i.e no distinction between versions of Influx and PNP support is dead given the dev has closed down the project.
