RPi cannot autostart Glances with --export influxdb

[Stuart Harrison]

Hi

I am having real trouble getting Glances to auto run with the --export influxdb command.

I have followed the instructions here:

However I am getting this error:

● glances.service - Glances

   Loaded: loaded (/etc/systemd/system/glances.service; enabled; vendor preset: enabled)

   Active: activating (auto-restart) (Result: exit-code) since Mon 2020-09-21 17:17:41 BST; 4s ago

  Process: 1778 ExecStart=/usr/local/bin/glances --quiet --export influxdb (code=exited, status=2)

 Main PID: 1778 (code=exited, status=2)

Here is my glances.service file contents:

[Unit]

After=network.target influxd.service

[Service]

ExecStart=/usr/local/bin/glances --quiet --export influxdb

Restart=on-failure

RemainAfterExit=yes

RestartSec=30s

[Install]

The log file is finding and reading my glances.conf file:

Here is my glances.conf file:

[influxdb]

host=localhost

port=8086

protocol=http

user=myuser

password=mypassword

db=glances

prefix=localhost

# Tags will be added for all measurements

#tags=foo:bar,spam:eggs

# You can also use dynamic values

#tags=system:`uname -a`

If I manually run this command in SSH terminal on the Pi it works OK and data is passed OK to InfluxDB / Grafana. 

glances --quiet --export influxdb

However I cannot get it to autostart after a reboot. 

If in the glances.service file I change the command to just: glances -w

Then that does work after rebooting the Pi and I can access the Glances web GUI OK. 

So why does it not work when using the command: glances --quiet --export influxdb ?

Please HELP !!

I think I’ve fixed it. I added the line:

User=pi

in to the glances.service file.

It appears to be loading now after a reboot, fingers crossed it remains that way.

But you already had user=myuser in your file?

I wonder why that was necessary?
