We are currently using Graphite to display Metrics. Only issue here is that Graphite does not provide graphs for our SNMP services.
I have found https://monitoring-portal.org/woltlab/index.php?thread/41124-graphite-with-snmp-checks-no-data-no-graphs/ that Grafana is going to work.
I tried this and it seems that Grafana is by default running on Port 3000. I guess that might not be a big issue at all but our server is in a closed network area and I would need to have Port 3000 open to display the Grafana website.
Is this needed if I want to use the Grafana Module?
