My librenms machine is very slow, I check the logs and I get this error, I don’t know why, please help.
Were you trying to enable metric exports to Prometheus? It looks like you left ‘http://127.0.0.1:9091’ in your $config[‘prometheus’][‘url’] settings instead of the actual IP of a Prometheus pushgateway?
So fixing that might help. But also be aware that Prometheus is currently considered Alpha level support and others have reported that configuring it led to slowdowns even when working.
