pfSense (FreeBSD 14.0) - Prometheus Node Exporter gives log errors - fix or suppress in log

On pfSense, I've enabled Prometheus Node Exporter, but it gives the following log errors each 15 seconds: Feb 15 09:53:57 vault node_exporter: ts=2024-02-15T08:53:57.164Z caller=collector.go:169 level=error msg="collector failed" name=uname duration_seconds=1.9687e-05 err="cannot allocate memory" Feb 15 09:53:57 vault node_exporter: ts=2024-02-15T08:53:57.164Z caller=collector.go:169 level=error msg="collector failed" name=zfs duration_seconds=1.6108e-05 err="couldn't get sysctl: no such file or directory" This is my Node Exporter settings: I'm not sure which collector gives the errors (on second thought, it seems to be some collectors that are not enabled, but still trying to collect). In any case, if I need it I might not be able to disable it, so another option would be to suppress the error messages in the log. I've tried: - Setting --log.level=none, but this is apparently not a valid log level - Creating a 01-node-exporter.conf file to suppress the messages, like this: if $msg contains "collector failed" then { stop } And put it inside /var/etc/syslog.d/. But this doesn't seem to suppress the messages either (this is working for me on Ubuntu). - I also tried [this advice](https://www.rsyslog.com/discarding-unwanted-messages/) , and instead put this into the 01-node-exporter.conf file, but to no avail: :msg, contains, "collector failed" ~ In addition, I've found the node_exporter config file, which is located at /usr/local/etc/rc.conf.d. This file contains: # This file is generated by the pfSense node_exporter package. # Do not edit this file, it will be overwritten automatically. node_exporter_enable="YES" node_exporter_listen_address="10.10.1.1:9100" node_exporter_args=" --collector.boottime --collector.cpu --collector.exec --collector.filesystem --collector.loadavg --collector.meminfo --collector.netdev --collector.textfile --collector.time --log.level=error" I'm inclined to think the erroneous log messages is a bug in Node Exporter for FreeBSD (because the collectors uname and zfs doesn't even seem to be enabled), so the short term solution would be to suppress the log messages.
