JS library for graph building

[bernerdschaefer]

The goal is to have a JS library which provides an API for building graphs from the prometheus rest endpoints. The idea is that this can be used along with #159 to provide a straightforward way of building custom dashboards. Ideally, it can also be used to power prometheus' own graph pane.

Now that there's console support, this should be "done" once I commit my JS library for graphing (and just graphing) back upstream.

http://review.prometheus.io/#/c/401/ has this.

Yes, and my deep apologies for not responding to that change yet - I want
to give this quite some thought. Ok, I really try to get to it sometime
this week (which might include the weekend ;))

@brian-brazil @juliusv
Did this graph library idea materialize?

I have some experience in data viz and can potentially contribute if there is a need.

[brian-brazil]

The graphing library that the console templates use would be a good base (API wise anyway), but it probably needs to be rewritten as frontend dev really isn't my area and it's a little bit buggy. https://github.com/prometheus/prometheus/blob/master/web/blob/static/js/prom_console.js

I was thinking the tricky bit would be bringing promdash in line with whatever we end up using (either factor what it has out, or switch it to the new core graph library) but as it looks like we're hoping to move in the direction of Grafana which means we can skip this.

That's leave the main work then as rewriting the expression browser, such as to support multiple expressions etc.

One wrinkle is that rickshaw which we're using for visualisation currently appears to be a dead project, so we need to switch to something else.

We'd love help with anything around this, as none of us are really frontend developers.

[thachmai]

Alright. I'll take a look at the current graph + promdash and the Grafana API to get a general idea. I will get back in touch with you guys in a couple of days with my findings.

[brian-brazil]

To be clear, we're only at Grafana as a potential replacement for Promdash. We'd still need a library to allow users embed graphs, including for console templates.

[thachmai]

OK. Would it make sense then to see how Grafana implements its graphs and see if there is something we can extract and reuse?

[fabxc]

If they are based on open source libraries (which I assume), it absolutely
makes sense.

We would be very happy to see someone giving our frontends a shot.

It looks like they likely use flot [1]
