Value stream analytics

Tier: Free, Premium, Ultimate Offering: GitLab.com, Self-managed, GitLab Dedicated

Value stream analytics measures the time it takes to go from an idea to production.

A value stream is the entire work process that delivers value to customers. For example, the DevOps lifecycle is a value stream that starts with the “manage” stage and ends with the “protect” stage.

Use value stream analytics to identify:

  • The amount of time it takes to go from an idea to production.
  • The velocity of a given project.
  • Bottlenecks in the development process.
  • Long-running issues or merge requests.
  • Factors that cause your software development lifecycle to slow down.

Value stream analytics helps businesses:

  • Visualize their end-to-end DevSecOps workstreams.
  • Identify and solve inefficiencies.
  • Optimize their workstreams to deliver more value, faster.

Value stream analytics is available for projects and groups.

Feature availability

Value stream analytics offers different features at the project and group level for FOSS and licensed versions.

  • On GitLab Free, value stream analytics does not aggregate data. It queries the database directly where the date range filter is applied to the creation date of issues and merge request. You can view value stream analytics with pre-defined default stages.
  • On GitLab Premium, value stream analytics aggregates data and applies the date range filter on the end event. You can also create, edit, and delete value streams.

Feature parity of project-level with group-level value stream analytics is achieved by using the new record ProjectNamespace. For details about this consolidation initiative, see the Organization documentation.

How value stream analytics works

Value stream analytics calculates the duration of every stage of your software development process.

Value stream analytics is made of three core objects:

  • A value stream contains a value stream stage list.
  • Each value stream stage list contains one or more stages.
  • Each stage has two events: start and stop.

Value stream stages

A stage represents an event pair (start and end events) with additional metadata, such as the name of the stage. You can configure the stages in the pairing rules defined in the backend.

Value streams

Value streams are container objects for the stages. You can have multiple value streams per group, to focus on different aspects of the DevOps lifecycle.

Value stream stage events

Events are the smallest building blocks of the value stream analytics feature. A stage consists of a start event and an end event.

The following stage events are available:

  • Issue closed
  • Issue created
  • Issue first added to board
  • Issue first added to iteration
  • Issue first assigned
  • Issue first associated with milestone
  • Issue first mentioned
  • Issue label added
  • Issue label removed
  • MR closed
  • MR merged
  • MR created
  • MR first commit time
  • MR first assigned
  • MR first deployed
  • MR label added
  • MR label removed
  • MR last pipeline duration

These events play a key role in the duration calculation, which is calculated by the formula: duration = end event time - start event time.

To learn what start and end events can be paired, see Validating start and end events.

How value stream analytics aggregates data

Tier: Premium, Ultimate Offering: GitLab.com, Self-managed, GitLab Dedicated
History
  • Introduced in GitLab 14.5.
  • Filter by stop date toggle added in GitLab 14.9
  • Data refresh badge added in GitLab 14.9
  • Filter by stop date toggle removed in GitLab 14.9
  • Enable filtering by stop date added in GitLab 15.0

Value stream analytics uses a backend process to collect and aggregate stage-level data, which ensures it can scale for large groups with a high number of issues and merge requests. Due to this process, there may be a slight delay between when an action is taken (for example, closing an issue) and when the data displays on the value stream analytics page.

It may take up to 10 minutes to process the data and display results. Data collection may take longer than 10 minutes in the following cases:

  • If this is the first time you are viewing value stream analytics and have not yet created a value stream.
  • If the group hierarchy has been re-arranged.
  • If there have been bulk updates on issues and merge requests.

To view when the data was most recently updated, in the right corner next to Edit, hover over the Last updated badge.

How value stream analytics measures stages

Value stream analytics measures each stage from its start event to its end event. Only items that have reached their end event are included in the stage time calculation.

By default, blocked issues are not included in the life cycle overview. However, you can use custom labels (for example workflow::blocked) to track them.

You can customize stages in value stream analytics based on pre-defined events. To help you with the configuration, GitLab provides a pre-defined list of stages that you can use as a template. For example, you can define a stage that starts when you add a label to an issue, and ends when you add another label.

The following table gives an overview of the pre-defined stages in value stream analytics.

Stage Measurement method
Issue The median time between creating an issue and taking action to solve it, by either labeling it or adding it to a milestone, whichever comes first. The label is tracked only if it already has an issue board list created for it.
Plan The median time between the action you took for the previous stage, and pushing the first commit to the branch. The first commit on the branch triggers the separation between Plan and Code. At least one of the commits in the branch must contain the related issue number (for example, #42). If none of the commits in the branch mention the related issue number, it is not considered in the measurement time of the stage.
Code The median time between pushing a first commit (previous stage) and creating a merge request (MR) related to that commit. The key to keep the process tracked is to include the issue closing pattern in the description of the merge request. For example, Closes #xxx, where xxx is the number of the issue related to this merge request. If the closing pattern is not present, then the calculation uses the creation time of the first commit in the merge request as the start time.
Test The median time to run the entire pipeline for that project. It’s related to the time GitLab CI/CD takes to run every job for the commits pushed to that merge request. It is basically the start->finish time for all pipelines.
Review The median time taken to review a merge request that has a closing issue pattern, between its creation and until it’s merged.
Staging The median time between merging a merge request that has a closing issue pattern until the very first deployment to a production environment. If there isn’t a production environment, this is not tracked.
note
Value stream analytics works on timestamp data and aggregates only the final start and stop events of the stage. For items that move back and forth between stages multiple times, the stage time is calculated solely from the final events’ timestamps.

For information about how value stream analytics calculates each stage, see the Value stream analytics development guide.

Example workflow

This example shows a workflow through all seven stages in one day.

If a stage does not include a start and a stop time, its data is not included in the median time. In this example, milestones have been created and CI/CD for testing and setting environments is configured.

  • 09:00: Create issue. Issue stage starts.
  • 11:00: Add issue to a milestone (or backlog), start work on the issue, and create a branch locally. Issue stage stops and Plan stage starts.
  • 12:00: Make the first commit.
  • 12:30: Make the second commit to the branch that mentions the issue number. Plan stage stops and Code stage starts.
  • 14:00: Push branch and create a merge request that contains the issue closing pattern. Code stage stops and Test and Review stages start.
  • GitLab CI/CD takes 5 minutes to run scripts defined in the .gitlab-ci.yml file.
  • 19:00: Merge the merge request. Review stage stops and Staging stage starts.
  • 19:30: Deployment to the production environment finishes. Staging stops.

Value stream analytics records the following times for each stage:

  • Issue: 09:00 to 11:00: 2 hrs
  • Plan: 11:00 to 12:00: 1 hr
  • Code: 12:00 to 14:00: 2 hrs
  • Test: 5 minutes
  • Review: 14:00 to 19:00: 5 hrs
  • Staging: 19:00 to 19:30: 30 minutes

Keep in mind the following observations related to this example:

  • This example demonstrates that it doesn’t matter if your first commit doesn’t mention the issue number, you can do this later in any commit on the branch you are working on.
  • The Test stage is used in the calculation for the overall time of the cycle. It is included in the Review process, as every MR should be tested.
  • This example illustrates only one cycle of the seven stages. The value stream analytics dashboard shows the median time for multiple cycles.

Cumulative label event duration

History
On self-managed GitLab, by default this feature is available. To hide the feature, an administrator can disable the feature flag named enable_vsa_cumulative_label_duration_calculation. On GitLab.com and GitLab Dedicated, this feature is available.

With this feature, value stream analytics measures the duration of repetitive events for label-based stages. You should configure label removal or addition events for both start and end events.

For example, a stage tracks when the in progress label is added and removed, with the following times:

  • 9:00: label added.
  • 10:00: label removed.
  • 12:00: label added.
  • 14:00 label removed.

With the original calculation method, the duration is five hours (from 9:00 to 14:00). With cumulative label event duration calculation enabled, the duration is three hours (9:00 to 10:00 and 12:00 to 14:00).

note
When you upgrade your GitLab version to 16.10 (or to a higher version), existing label-based value stream analytics stages are automatically reaggregated using the background aggregation process.

How value stream analytics identifies the production environment

Value stream analytics identifies production environments by looking for project environments with a name matching any of these patterns:

  • prod or prod/*
  • production or production/*

These patterns are not case-sensitive.

You can change the name of a project environment in your GitLab CI/CD configuration.

Value stream analytics metrics

History

The Overview page in value stream analytics displays key metrics of the DevSecOps lifecycle performance for projects and groups.

Lifecycle metrics

Value stream analytics includes the following lifecycle metrics:

  • Lead time: Median time from when the issue was created to when it was closed.
  • Cycle time: Median time from first commit to issue closed. GitLab measures cycle time from the earliest commit of a linked issue’s merge request to when that issue is closed. The cycle time approach underestimates the lead time because merge request creation is always later than commit time.
  • New issues: Number of new issues created.
  • Deploys: Total number of deployments to production.

DORA metrics

Tier: Ultimate Offering: GitLab.com, Self-managed, GitLab Dedicated
History
  • Introduced lead time for changes DORA metric in GitLab 14.5.
  • DORA API-based deployment metrics for value stream analytics for groups were moved from GitLab Ultimate to GitLab Premium in GitLab 14.3.
  • Introduced time to restore service tile in GitLab 15.0.
  • Introduced change failure rate tile in GitLab 15.0.

Value stream analytics includes the following DORA metrics:

  • Deployment frequency
  • Lead time for changes
  • Time to restore service
  • Change failure rate

DORA metrics are calculated based on data from the DORA API.

If you have a GitLab Premium or Ultimate subscription:

  • The number of successful deployments is calculated with DORA data.
  • The data is filtered based on environment and environment tier.
note
In GitLab 13.9 and later, deployment frequency metrics are calculated based on when the deployment was finished. In GitLab 13.8 and earlier, deployment frequency metrics are calculated based on when the deployment was created.

Label-based stages for custom value streams

To measure complex workflows, you can use scoped labels. For example, to measure deployment time from a staging environment to production, you could use the following labels:

  • When the code is deployed to staging, the workflow::staging label is added to the merge request.
  • When the code is deployed to production, the workflow::production label is added to the merge request.

Label-based value stream analytics stage

Example for custom value stream configuration

Example configuration

In the example above, two independent value streams are set up for two teams that are using different development workflows in the Test Group (top-level namespace).

The first value stream uses standard timestamp-based events for defining the stages. The second value stream uses label events.

Troubleshooting

100% CPU utilization by Sidekiq cronjob:analytics_cycle_analytics

It is possible that value stream analytics background jobs strongly impact performance by monopolizing CPU resources.

To recover from this situation:

  1. Disable the feature for all projects in the Rails console, and remove existing jobs:

    Project.find_each do |p|
      p.analytics_access_level='disabled';
      p.save!
    end
    
    Analytics::CycleAnalytics::GroupStage.delete_all
    Analytics::CycleAnalytics::Aggregation.delete_all
    
  2. Configure a Sidekiq routing with for example a single feature_category=value_stream_management and multiple feature_category!=value_stream_management entries. Find other relevant queue metadata in the Enterprise Edition list.
  3. Enable value stream analytics for one project after another. You might need to tweak the Sidekiq routing further according to your performance requirements.
