error on getting ping status

janjanson

Hi I did the installation as described in
https://mycontroller.org/docs/installation/quick-installation/executable-binary/
and
https://mycontroller.org/docs/getting-started/install-influxdb/

the http://192.168.1.102:8086/ shows :
404 page not found
my question:
WTF? did someone follow the installation instructions?

--- DETAILS ---

the influx installed, up and running, listening on 8088

sorry the stupid forum made some idiotic formating from my text... no intentions... plus I must wait to post this message

@janjanson welcome to MyController forum. the forum responsive for Markdown language.

Looks like you have entered a wrong port number on the mycontroller.yaml file for the influx db. You are running influxdb on 8086 but on the configuration file it is set to 8080

you should have something like this

database:
  metric:
    disabled: false
    type: influxdb
    uri: http://127.0.0.1:8086 # must be updated with your host ip address

BTW, MyController supports InfluxDB 1.8.x or above. MtyController have not tested with influx db 1.6.x
