[BUG] INFLUXDB_HOST Variable is Ignored

[elzik]

Describe the bug When trying to set the INFLUXDB_HOST environment variable, the value set is ignored and Scrutiny still tries to connect to localhost:8086. Perhaps I am using the wrong image (master-web)?

Expected behavior When the the INFLUXDB_HOST environment variable is set it should be honoured.

Docker Run This is used on Unraid, so please excuse the noise in the docker run command. However, you can see that INFLUXDB_HOST is set to http://192.168.0.12:8086

docker run -d --name='scrutiny-web' --net='bridge' --privileged=true -e TZ="Europe/London" -e HOST_OS="Unraid" -e HOST_HOSTNAME="Tower" -e HOST_CONTAINERNAME="scrutiny-web" -e 'INFLUXDB_ADMIN_TOKEN'='<redacted>' -e 'INFLUXDB_ORG_ID'='<redacted>' -e 'INFLUXDB_HOST'='http://192.168.0.12:8086' -e 'INFLUXDB_SCRUTINY_BUCKET_BASENAME'='scrutiny_metrics' -l net.unraid.docker.managed=dockerman -l net.unraid.docker.webui='http://[IP]:[PORT:8093]' -l net.unraid.docker.icon='https://raw.githubusercontent.com/selfhosters/unRAID-CA-templates/master/templates/img/scrutiny.png' -p '8093:8080/tcp' -v '/run/udev':'/run/udev':'ro' -v '/dev/disk':'/dev/disk':'ro' -v '/mnt/user/appdata/scrutiny-web/config':'/opt/scrutiny/config':'rw' 'ghcr.io/analogj/scrutiny:master-web'

Hey @elzik Where did you see the INFLUXDB_HOST environmental variable referenced? I may have some old documentation I need to update

since the key for the influxdb host in the config file is web.influxdb.host, the associated environmental variable is SCRUTINY_WEB_INFLUXDB_HOST

If you set that variable, everything should work correctly. I'll close this issue for now, but please reopen/comment if this doesnt work for you.

@AnalogJ thanks for your reply.

Where did you see the INFLUXDB_HOST environmental variable referenced?

Here https://github.com/AnalogJ/scrutiny/blob/master/docs/TROUBLESHOOTING_INFLUXDB.md#setup-environmental-variables

the associated environmental variable is SCRUTINY_WEB_INFLUXDB_HOST

Thanks, that does get rid of the previous error I was seeing but I get another one now instead:

I find this even stranger given my docker run command. I haven't specified a host of http://http or an IP address of 194.168.4.100 anywhere. I wonder if some of my other environment variables are wrong - possibly just another docs issue? Would you like me to reopen this issue or create a new one?

[martadinata666]

i assume that you are using -e 'INFLUXDB_HOST'='http://192.168.0.12:8086' then replace the env to -e 'SCRUTINY_WEB_INFLUXDB_HOST'='http://192.168.0.12:8086' ? It should be only the IP or container name like SCRUTINY_WEB_INFLUXDB_HOST=db or SCRUTINY_WEB_INFLUXDB_HOST=192.168.0.12

[AnalogJ]

@elzik ah. Those environmental variables are just for simplifying the scripts for configuring your influxDB manually. The webapp (running in docker) doesn't care about those environmental variables at all. only SCRUTINY_* env variables (and the config file) are considered.

As @martadinata666 mentioned, you need to remove the scheme component from your environmental variable. SCRUTINY_WEB_INFLUXDB_HOST expects an IP address or domain name (no http:///https:// prefix)
