grafana 7.0 [4a3cd743]

Tags: computers

1. New Panel Edit UI

  • 6.0 made it easy to change visualization type

    • created a lot of dead space
  • 7.0 wanted to make options more consistent and define override rules

  • "field" tab impacts all the data

    • overrides
    • bar guage
  • New transformations -> joining of timeseries
  • Cell styles, gauges

  • Much more up to date, exposing new transformation pipeline

    • data source -> panel defaults -> panel overrides -> visualization

2. Transformation

  • Single place where users can tweak the structure of data
  • Takes effect for every visualization
  • Shapes the data
  • Not about doing complex arithmetic
  • Panel can reuse same data from another query, piping the data into all sorts of panels
  • Transform timeseries into columns

3. Look at Raw Data

  • You can now inspect and download raw with the "inspector" in the panel manager
  • Exposes the underlying raw data

4. Issues and Debugging with Queries

  • Grafana comp presentation

  • When zooming out, data no longer makes sense

    • Data rollup feature has been implemented

      • Rollup tells you when the data was being read from a rollup
      • 8 days in metric tank, for example
    • As well as "metadata"

  • Plot lines as points to debug

    • Fetching multiple series will cause some optimization, triggers it to use rollup data

  • "Stats" panel tells you how long a query took

    • "metricplan" statistics tells you how long a query works
  • Grafana can hook up to a jaeger datasource and look at it directly from grafana
  • Transforms and outer joins

  • Timezone support features

    • Transforms all graphs into a single time zone

  • Plan to support per panel, per row?

    • Not really
  • Gauages and singlestat panels have new layout engine
