I'm a very happy Grafana user. The move to a server based app worried me at first, but it's been humming along nicely the entire time. It's a shame that graphite is still so hard to install/configure (at least from rhel 6 and lower - things might be better on other distros/versions) though. If you're looking to start making some money as a business, I'd be spending a bit of time making sure the data sources are as easy to stand up as possible.

Congratulations on the new release and, really, fantastic work!

I have some random historical meteorological data (multiple time series, ~3 million values, a couple of parameters, nothing big) lying around in a MySQL database which I would love to explore. Grafana looks like a nice tool to at least visualize it.

Which supported data source would you recommend for a quick test ride?

Looks like a nice release! One thing I really miss in grafana and seems like it's not included is alerts. It would be so damn convenient to have data visualization and alerts on the same system because usually they are strongly related from the user point of view. And, well, one thing less to setup and maintain. However, I am aware of the debate whether alerts do actually belong to grafana, or should it be responsibl…

Alerting is on the way :D https://github.com/grafana/grafana/blob/e69658128cd972d94eb8...

I'd love to hear how others manage it too. I have a bunch of little python scripts in cron jobs that pull / compare numbers from graphite and then post to slack. Adhoc but at least there was nothing much to set up / maintain and it's totally flexible. As things expand though I'd definitely like to move to something to look after it for me.

We're extremely happy campers here combining the Grafana dashboard with https://prometheus.io/ Datastore and Alerts. That project has some serious traction and is one of just a few that seems actually built for the cloud and distributed systems first , as it's primarily role and not host based.

Can I ask how you manage logs?

My minimal understanding is that prometheus is time-series only so you'd have to supplement with something like ElasticSearch to aggregate logs. Does this mean you are alerting only on metrics or have multiple alert systems or ...?

Interesting. I briefly looked at it previously but have never had the chance to play around.

Did you (or has anyone else) migrate your legacy data from graphite to prometheus? What's the grafana support like on top? Do you need to run a proxy or something to support the same querying or does it require reworking all the existing graphs?

Things I wish were included in that release:

- Some amount of caching/pre-fetching so moving the graph around doesn't take a few seconds each time. At least in the cases where I am zooming in and all the data is already loaded on the client it shouldn't need a network round trip.

- The ability to drag the charts left and right by keeping the shift key pressed, as is the default on Dygraphs charts (dygraphs.com)

- Switch from Flot to Dygraphs would make client-side rendering faster (at least for the typical line charts)

I use icinga2 (nagios-like monitoring) to store perfdata/metrics in graphite, then use Grafana to visualize those stats.

Not openTSDB. That's by far the most difficult to set up. It's also the best in terms of scalability and performance.

Grafana is mainly built around time series databases that have good roll ups and are usually quite fast. Graphite queries usually only take 50-150ms (except some rare cases). This is changing a bit with newer slower time series databases that don't have good roll ups or are generally slow.

The main problem with prefetching or doing delta fetches is that some queries depend on the whole time range to execute (like moving average, integral, derivate).
