Node Exporter Startup Options

[card...@gmail.com]

Having issues when starting the node exporter within systemd/services. when I tell it to use collector.filesystem.ignored-mount-points it does not work. 

[Unit]

Description=Prometheus Node Exporter

[Service]

User=root

Restart=on-failure

ExecStart=/apps/vision/prometheus/node_exporter-0.16.0-rc.1.linux-amd64/node_exporter \

                                        --collector.filesystem.ignored-mount-points="^/(dev|home)($|/)"

[Install]

WantedBy=multi-user.target

When I start via command line, no issues and /home is removed.

/apps/vision/prometheus/node_exporter-0.16.0-rc.1.linux-amd64/node_exporter --collector.filesystem.ignored-mount-points="^/(dev|home)($|/)"

Do you get any logs when running under systemd?

I get nothing.

When ran manually it is good "/apps/vision/prometheus/node_exporter-0.16.0-rc.1.linux-amd64/node_exporter --collector.filesystem.ignored-mount-points="^/(dev|home)($|/)" --log.level="debug""

from start up file:

ExecStart=/apps/vision/prometheus/node_exporter-0.16.0-rc.1.linux-amd64/node_exporter \

                                      --collector.filesystem.ignored-mount-points="^/(dev|home)($|/)" \

                                    

When I add   --log.level="debug" it will not start

Nothing?

Do you get service starting/started messages?

I see the service starting and started but no errors and the mounts I am excluding are showing up. If I create a script and call that from the service, it works. 

[Nicholas Capo]

It seems like a systemd problem.

Could you post a complete copy of the working and non-working systemd unit files?
