# Analyze GitLab usage **(FREE)**
|
|
|
|
## Instance-level analytics
|
|
|
|
Instance-level analytics make it possible to aggregate analytics across
|
|
GitLab, so that users can view information across multiple projects and groups
|
|
in one place.
|
|
|
|
[Learn more about instance-level analytics](../admin_area/analytics/index.md).
|
|
|
|
## Group-level analytics
|
|
|
|
> Moved to GitLab Premium in 13.9.
|
|
|
|
GitLab provides several analytics features at the group level. Some of these features require you to use a higher tier than GitLab Free.
|
|
|
|
- [Application Security](../application_security/security_dashboard/index.md)
|
|
- [Contribution](../group/contribution_analytics/index.md)
|
|
- [DevOps Adoption](../group/devops_adoption/index.md)
|
|
- [Insights](../group/insights/index.md)
|
|
- [Issue](../group/issues_analytics/index.md)
|
|
- [Productivity](productivity_analytics.md)
|
|

|
|
## Project-level analytics
|
|
|
|
You can use GitLab to review analytics at the project level. Some of these features require you to use a higher tier than GitLab Free.
|
|
|
|
- [Application Security](../application_security/security_dashboard/index.md)
|
|
- [CI/CD & DORA](ci_cd_analytics.md)
|
|
- [Code Review](code_review_analytics.md)
|
|
- [Insights](../project/insights/index.md)
|
|
- [Issue](../group/issues_analytics/index.md)
|
|
- [Merge Request](merge_request_analytics.md), enabled with the `project_merge_request_analytics`
|
|
[feature flag](../../development/feature_flags/index.md#enabling-a-feature-flag-locally-in-development)
|
|
- [Repository](repository_analytics.md)
|
|
- [Value Stream](value_stream_analytics.md)
|
|
|
|
## User-configurable analytics
|
|
|
|
The following analytics features are available for users to create personalized views:

## Definitions
|
|
|
|
We use the following terms to describe GitLab analytics:
|
|
|
|
- **Mean Time to Change (MTTC):** The average duration between idea and delivery. GitLab measures
|
|
MTTC from issue creation to the issue's latest related merge request's deployment to production.
|
|
- **Mean Time to Detect (MTTD):** The average duration that a bug goes undetected in production.
|
|
GitLab measures MTTD from deployment of bug to issue creation.
|
|
- **Mean Time To Merge (MTTM):** The average lifespan of a merge request. GitLab measures MTTM from
|
|
merge request creation to merge request merge (and closed/un-merged merge requests are excluded).
|
|
For more information, see [Merge Request Analytics](merge_request_analytics.md).
|
|
- **Mean Time to Recover/Repair/Resolution/Resolve/Restore (MTTR):** The average duration that a bug
|
|
is not fixed in production. GitLab measures MTTR from deployment of bug to deployment of fix.
|
|
- **Velocity:** The total issue burden completed in some period of time. The burden is usually measured
|
|
in points or weight, often per sprint. For example, your velocity may be "30 points per sprint". GitLab
|
|
measures velocity as the total points or weight of issues closed in a given period of time.
