Thanks for leading the Grafana project! As a color blind user, I find it difficult to read the dashboards created by others. How can I help any efforts to increase Grafana's accessibility?

I'm also colorblind and a heavy Grafana user but I haven't had much difficulty reading dashboards. What are you having trouble with? The most trouble I've had is colors of multiple lines on a chart being too similar but being able to use the mouse to select a line and see what the line is and its value helps there.

The default palette is definitely a challenge, since it has pretty low contrast and Grafana's defaults use a lot of thin lines.

I especially have trouble matching colors in a legend with the drawn objects in the graph. The best help has been the hover panel, but it's unsorted by default and the highlight contrast on the panel for hovering over a line is pretty dim.

Hi, my name is Torkel Ödegaard. Grafana project creator & lead. Here to answer any questions.

Are we any closer to having some kind of anomaly detection in grafana (when using prometheus)?

Have you seen this talk/blog from last year's Monitorama about anomaly detection with Prometheus:

Just wanted to say thanks for an awesome piece of software. It's one of those "I can't believe it's doing it and doing it this well, and it's free" kind of projects. For me, Grafana together with ElasticSearch and InfluxDB+Telegraf is pure monitoring/analysis/alerting bliss. Stay true to your roots and don't get tempted to turn into Kibana ;)

At work we have to compile everything from source because compliance, and Grafana is one of the harder ones to get right. There used to be good documentation for it a few versions back but I can't seem to find it lately. Is there any good documentation on how to get Grafana compiled from source?

Checkout the contribute folder on GitHub. Here is the developer guide:

since when? :) A few things have been added that may help: 1. only visible data is queried and loaded 2. If you have multiple panels that use the same data, you can now just reuse the results (or a subset of the results) in a new panel. This will cut down on additional queries that may not be necessary

i see you still have plans to continue with uPlot testing :) https://github.com/grafana/grafana/pull/21835

absolutely -- with everything else for 7.0 that did not make the cut. But would love to work more with your frankly amazing library :)

I have a Grafana dashboard set up for all of my power/hvac/internet infrastructure (I live off grid) and it's an amazing tool. I'm excited to try out some of the new features. Without Grafana I wouldn't have been able to diagnose a charge issue my solar controller has on partially cloudy days. Very grateful to the devs, thank you all for the hard work.

Is it now possible to create a horizontal lined based on a single value (either a fixed or a computed number)?

For example when I'm tracking the power grid frequency, I would like to add two lines at 50.05 and 49.95 Hz, as well as one at 50 Hz (with different color).

Others have voiced their desire to display a horizontal line at the 95th percentile in a bandwidth usage graph.

I just built it from sources because of the same reason. What are the issues on your side?

Does the new plugin architecture allow me to provision plugins from a config file on startup? Like installing the Kubernetes App without `grafana-cli plugins install kubernetes-app`

Someone already replied but I should add that most if not all config parameters can be passed to the container through env variables.

It would be nice to have yearly, monthly, weekly and other recurring graph, I tried to hack it with sql window function, but it gives lot of problems. https://community.grafana.com/t/yearly-monthly-weekly-and-ot...

I have this set up to compare my last three days of solar output. I don't remember off the top of my head how I did it but I might be able to help out. What DB are you running on top of?
