Performance

Monitoring

We have a performance dashboard available in one of our Grafana instances. This dashboard automatically aggregates metric data from sitespeed.io every 6 hours. These changes are displayed after a set number of pages are aggregated.

These pages can be found inside a text file in the gitlab-build-images repository called gitlab.txt Any frontend engineer can contribute to this dashboard. They can contribute by adding or removing urls of pages from this text file. Please have a frontend monitoring expert review your changes before assigning to a maintainer of the gitlab-build-images project. The changes will go live on the next scheduled run after the changes are merged into master.

There are 3 recommended high impact metrics to review on each page:

• First visual change
• Speed Index
• Visual Complete 95%

For these metrics, lower numbers are better as it means that the website is more performant.
