Re: Dashboarding graphs of a single metric for every interface in a node or category

I’m sure others will have better advice than me as I’m also new to OpenNMS, but here goes:


  1.  Grafana is one of the best options for this as it can use variables allowing you to build a dashboard will “all metrics for a selected node” or “a selected metric for all nodes” quite easily
  2.  Have you looked at the KSC reports?  You can add any of the RRD/backshift graphs you like to a single report and then display that report.  It’s not dynamic, but it will do what you’re looking for in a static world (i.e. you configure which specific metrics you want to see on that report and then run that report).

Subject: [opennms-discuss] Dashboarding graphs of a single metric for every interface in a node or category

Hi all,

I've been experimenting with OpenNMS to see if it will fit the needs of my organization, and there's a couple of feature of our current NMSes I can't seem to replicate with OpenNMS without a lot of messing around configuring grafana, so I'm wondering if there's something I'm missing.

What I need is a way to view graphs from multiple interfaces on multiple nodes on a single page, but viewing only one metric - be that throughput or errors or whatever. At the moment I can easily get graphs for every interface on a single node, but I get all metrics for every interface which means I can't get a good view of e.g. just the throughput across all the interfaces on a device.

Another use case is being able to graph all of the interfaces involved in connectivity for a business service and being able to select whether to see throughput, errors, bits in/out, etc. for all the interfaces at once.

As far as I can see it's impossible in OpenNMS to get graphs for multiple nodes at a time in any way. For all of its other weaknesses this is one thing (the only thing?) that Statseeker does quite well.

Am I missing something? Is there a way to do this without having to set up queries manually in grafana for everything I want to be able to view?

Thanks.
