Description

I tried to install node_exporter and whilst the install appeared to complete successfully, I noticed it did not appear to be running.

1) I first tried curling <ip address of router>:9100 and got no response.
2) The confirmed it was not running by ssh'ing into the pfsense box and running both ps and sockstat
3) Examined the logs and saw: "/rc.start_packages: ERROR: Could not open {/usr/local/etc/rc.conf.d/node_exporter} for writing"

I then attempted to reinstall the package. Got the following response: ==========================================================================

Then checked the logs again and saw the same errror:
/rc.start_packages: ERROR: Could not open {/usr/local/etc/rc.conf.d/node_exporter} for writing

Its also worth noting that there is no menu entry for node_exporter under services either, indicating that more than the rc file failed to be created.

After ssh'ing into the pfsense box I can see the directory /usr/local/etc/rc.conf.d does not exist. After creating the directory and attempting to reinstall the package again: ==========================================================================

This time I can see the menu item node_exporter but the logs state the service did not start. From the logs I can see:
/usr/local/etc/rc.d/node_exporter.sh: WARNING: failed to start node_exporter

However I can read metrics from <ip address of router>:9100

Looking at the directory I see both /usr/local/etc/rc.d/node_exporter.sh and /usr/local/etc/rc.d/node_exporter
