Display Number of Errors

To show the number of errors in a system, you could count them using the count() function.

  1. From the Search tab, type this query in the Query Editor:

    logscale
    loglevel = /error/i
| count()

  2. Save your widget as explained at Create Widgets

  3. Click the menu icon on top-right of the widget and select Styling, the Styling panel is displayed on the side of the widget:

  4. Set the properties as desired:

    • Layout → choose Radial Needle type in this example

    • Value → choose Raw format

    • Colors → adjust the colors for the thresholds you have defined, thus creating a custom palette.
