Builds can consist of multiple stages and each stage is executed on one of Continua's Agents. Before a stage is executed, the Continua server selects an agent to run the stage and sends all required information to the agent. This agent then runs all the actions on the stage before it sends any relevant information back to the server. For more information on how the server and agents work, check out the Distributed Architecture page.

Automatically Triggering Builds
Triggers can be created on a build's configuration that will automatically 'trigger' a build on certain events. Triggers can be broken up into 3 sections:
...
- Build Priority: Normal
- Associate: Most recent changesets
- Comment: No comment set
- Repository Branch: All repository branches will be set to their default.
- Variables: All variables will be set to their default values.
Queued Builds
- .
The Build Queue
The Build Queue is where all builds wait until an agent becomes available that can run the next stage in the build. An agent is only eligible to run a stage if the agent has all the required applications installed so that it can execute every action on that stage.
Determining Build Bottlenecks
If there are multiple builds waiting for an agent, Continua will use the Build Priority property of the build to determine which build will be sent to the agent.
Queue Conditions
Queue Conditions can be created on a build's parent configuration which control when a build can leave the queue and begin executing. If a queue condition has not been met then the build will sit on the queue indefinitely until that queue condition has been met.
Stage Awaiting Agent
If you are frequently seeing builds waiting for available agents then there are more concurrent builds running then there are agents. By adding additional agents to Continua you should see a decrease in the number of builds that are waiting for an agent. Note that additional agents are only available to customers that have purchased additional concurrent builds for their Continua CI instance.
