Configure runner concurrency and inspect step queue
Runner step queue
Each workspace features a global queue for all steps to be run on self-hosted runners across all pipelines in that workspace.
Each step remains in the queue while it is waiting for a compatible runner to pick it up, and while being built by that runner. Once the step is completed or stopped, it is removed from the step queue.
Step queue enforces two limits:
The total number of steps: Queue allows up to 1,000 steps across multiple pipelines of the workspace
Runner concurrency limit: The maximum number of steps to be built on runners at once
Configure runner concurrency
By increasing the runner concurrency limit, you allow more steps in your workspace to be built at the same time. Lower limit value might mean that steps will have to spend more time in the queue, waiting for their turn to be built.
You can update the runner concurrency limit only for Standard and Premium workspaces. Your workspace also has to be linked to an Atlassian organization.
Until June 3, 2026, the concurrency limit applies only to version 5 runners. You can use all the versions during the transition, but only version 5 will support new features.
To update the runner concurrency limit, select your profile and avatar, then select a workspace from the Recent Workspaces list or select All workspaces to open a page listing all the workspaces in which you are a member.
上部のナビゲーション バーにある [設定] (歯車アイコン) を選択します。
[設定] ドロップダウン メニューから [ワークスペース設定] を選択します。
[Pipelines] セクションで [Workspace runners (ワークスペース ランナー)] を選択します。
You will see the current value of the concurrency limit. To update it, select Change limit. If you don’t see the Change limit button, you might need to link your workspace to an Atlassian organization
In the Set your concurrency limit dialog, specify the New concurrency limit value and select Update limit.
Verify the change you’re about to make, then select Confirm.
Inspect the step queue
You can check important parameters of the step queue to get an idea of how the runners are utilized in your workspace.
To check the step queue state, go to the workspace you want to check.
上部のナビゲーション バーにある [設定] (歯車アイコン) を選択します。
[設定] ドロップダウン メニューから [ワークスペース設定] を選択します。
[Pipelines] セクションで [Workspace runners (ワークスペース ランナー)] を選択します。
You will see Queue analytics and Steps in queue sections:
Queue analytics includes the average and maximum times a step spends waiting in the queue to be assigned to a runner, as well as the total number of steps in the queue and the number of steps being currently built. Note that the values displayed reflect the current snapshot of the queue, excluding any historical data.
Steps in queue displays the top 5 steps in the queue, their status, and the related repository.
