Using radar-plots with influxDB #1

Closed laimaretto closed 6 years ago

Hi! I’ve tried your plugin. It’s very very nice … thank you …

Now, I have a couple of questions. In the readme file it's been explained that the plugin in has been tested out with ElasticSearch as data-source (I’m using influxdb).

Let me show you an example of what I'm trying to do: I’m trying to measure the number of messages (LSA) per OSPF Area in a network. To do this, I’ve constructed the following query …

… and obtained this plot, which is fine and consistent with other plots that I’ve made for the same KPI; so far, so good…

Now, as far as I can understand, the plugin is using time (EPOCH) as the axis for the radar. If you see, because of that, I'm limiting the search to the last 6 samples (hence the hexagon).

What I’d like to achieve is that the ‘tags’ of the influx measurement to be these axis (in my case: ‘0.0.0.0’, ‘0.0.0.2’, ‘0.0.2.4’). So, if that could be possible, instead of an ‘hexagon’, I would have a ‘triangle’, being each corner of it, each of the influx measurement's tags.

Do you think that is possible to achieve with influxdb?

thanks!

Did you try to add another group ? In Elastic, the first aggregation group is used for the diagonals and the second to determine the series names.

I did not play with Influx DB since a long time but I will try to check that by the end of the week if I have a few hours to spare. Tell me if the dual groups trick does work for you.

I committed a new version can you check against it. There is a new option or Influx in the configuration panel.

Hi! Sorry for the delay. So I've tried your update and it's much better!

Now the plugin uses tags as axis which is pretty good. In the example, 1Gbps, 10Gbps, etc, are tags, while rxRate and txRate are the fields/KPIs of the influx measurement.

I've noticed, though, that to plot several fields, these must be obtained from different queries ...

I believe that the possibility of establishing several fields on the same query, is a plus. Also, being able to define the units of the axis would be nice.

Thanks any way for the update! I'll keep on using it to see if I find anything else!

Thanks again!
