grafana 7.0

Tags: computers

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

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

Look at Raw Data

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

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
