Objective
You can add a horizontal line to a Cribl Search graph. This can be useful for showing that values are exceeding specific thresholds.
For example, you might want to highlight where workers surpass 100% for cpuPerc as below.

Environment
- Cribl Search
Procedure
To do this, add the following to the end of your query:| extend <value name> = <value>
For example, if you’d like to show where CPU usage is exceeding 90 percent, you’d use the following:
| extend cpu_perc = 90
