Multiple graphite instances about grafana

[damm]

Why not use CLUSTER_SERVERS and have 1 unified graphite render url?

On that subject how do you normally compare graphs between datacenters? what tools?

[torkelo]

If this is something that more find useful I guess we could have a graphiteUrl override per dashboard or per specific graph. But I do not think this will be a priority unless more will need this.

+1 on multiple graphite. I'm ok with not having it 'per graph'. In the panel pickdown where we choose 'Graphite', I'd be ok with replacing that with something like 'graphite dc1', 'graphite dc2'. But I have no idea how that dropdown works.

As it pertains to @damm comment. These have duplicate metrics since they are 'per datacenter' carbons. So they will not work as advertised since the first response from a carbon host wins the race in that type of setup.

@phobos182 Yeah I gathered that much; which is why I was inquiring at what tools were used here. I am used to the pull downs in Graphitus and quite fond of them; that's how I have managed multiple datacenter dashboards previously.

@phobos182 is spot on. Each DC cluster has the same metrics (Say requests per second for that DC's cluster). We're trying to avoid having to have a multiple dc level dashboard, because sometimes its nice to just glance a single web page and see how all DC's are doing at once.

Its not really that we're looking to compare graphs from multiple dc's (nor to try to render metrics from multiple clusters on a single graph), its more that we're looking for something that lets us have a single page with individual graphs from all the clusters. This way we can see something like the Requests/sec graph from every DC on a single page. Its nice being able to do that without having to drill through 6 different dashboards.

Our solution right now is to either fire up multiple instances of something like grafana, or most commonly to manually throw together a single webpage one off that pull's in Graphite svg's from all the instances on a single page.

👍 for that feature. We have a similar use cases with multiple graphite backends.

[xkilian]

This feature, along with a host of others would be possible if Grafana would have a back-end component that stored role based preferences. These preferences would be loaded on "login" to Grafana. Of course you could have a builtin Grafana configuration setting for default dashboards, default tags, default back-ends, etc. But these are all static configs. Having a real role based system would provide an enterprise grade experience for users.

+1 For multiple backends, but really, +1 for role based back-end to make all features more dynamic.

ps. torkelo superbe job on grafana.

[phobos182]

Nice work. Will give this a try shortly.

Verified working on my installation. Great job. Should update the docs to have a "," at the end of the setting since it's a hash in case ppl copy + paste (like I did). ;)

[torkelo]

Great and thanks!

Any thoughts on having multiple data sources on an individual panel? Eg, adding a "datasource" attribute to the targets list?

[edasque]

👍

+1 great feature & nice work. Would be awesome to also have the ability to create a single/individual graph utilising metrics pulled from different datasources as kkinder mentioned.

[wk66]

Yes it would be awesome to have dataseries from different datasources in one panel/graph!
