What have you configured in Grafana for that data source?
Do not be misled by selecting a new data source as Influx and seeing
“http://localhost:8086” in the box and thinking that is a default value - it
is not - it is an example, and if you’re happy with it, you still have to type
it in yourself.
I think this is very poorly indicated in the user interface.
also I got to see below error when try to re-install InfluxDb - any help on this please -
[root@aws185 ~]# sudo yum localinstall influxdb-1.8.0.x86_64.rpm
Loaded plugins: fastestmirror
Examining influxdb-1.8.0.x86_64.rpm: influxdb-1.8.0-1.x86_64
influxdb-1.8.0.x86_64.rpm: does not update installed package.
Nothing to do
