Purpose

Pipeline Mean Time to Recovery shows the average time a pipeline takes to recover from a failure.

How metric helps

Pipeline Mean Time to Recovery helps to reveal an overall efficiency of an integration process and to highlight the most problematic entities (branches).

How it works

Chart overview

Chart shows Pipeline Mean Time to Recovery in minutes - Axis Y by calendar week - Axis X. The number of series in the chart is a number of selected branches in Project Configuration for a Git Lab CI data source. Legend shows the last values of the metric by branch. For series the system shows the last value for each branch in each series.

When hover over a series hint appears:

• 1st row <week start-end date>

• 2nd row <Branch name>: <metric value in %>

• 3rd row <Pipeline Mean Time To Recovery>

Next to the chart name there is a link to GIT repository ('arrow').

Calculation formula

Red Pipeline Time segment = timestamp of the pipeline 'red' status end - timestamp of the pipeline 'red' status start

Pipeline Mean Time To Recovery = ∑Time To Recovery/N,    

where

Time To Recovery, min = timestamp of ‘green’ pipeline start - timestamp ‘red’ pipeline start;

N is a number of Red Pipeline Time segments.

RAG thresholds: n/a.

Calculation is illustrated in the picture below:

Data Source

Data for the metric can be collected from Jenkins/GITLab CI. When using Jenkins make sure Pipeline plugin is installed.
