Circuit Breaker Information
Integration Server gathers circuit breaker statistics for each service with a configured circuit breaker.
Note:
Services that belong to a package listed in the watt.server.stats.packages.exclude property do not appear in the Circuit Breaker Information tab.

Note:
The circuit breaker feature is available by default for a service that resides on a Microservices Runtime. To use the circuit breaker feature with Integration Server, your Integration Server must have additional licensing.
If a circuit breaker is not configured for any service, the Circuit Breaker Information table displays the message "No Services with a Circuit Breaker Enabled".
Statistics for each service with a configured circuit breaker
Column | Description |
Package | The package that contains the service. Note:
This column is not displayed by default. Click > Show Columns to view this column. |
Name | The fully qualified name of the service for which a circuit breaker is configured. |
State | The state of service. The state of the circuit. The circuit state can be one of the following: ![*](chapterTOC_bullet.png) Closed. The service executes. ![*](chapterTOC_bullet.png) Open. The service does not execute. Instead, depending on the circuit breaker configuration, the service returns an exception or executes an alternative service. ![*](chapterTOC_bullet.png) Half-Open. The first request for this service since the circuit state changes to half-open results in service execution. All other requests wait. If the service executes successfully, the circuit is closed and waiting requests execute. If the service ends with a failure exception, the circuit is re-opened. ![*](chapterTOC_bullet.png) Open Time. Time when circuit was opened. |
Open Time | Time when action was performed to close the circuit i.e. to retry execute call. |
Half-Open Time | Attempt to retry the execution of the actual Service is being made. If successful, Circuit is Closed; if unsuccessful, Circuit is Opened. |
Closed Time | Time when circuit was last closed. Time here represents the last execution of a request that was successful. |
Open Count | Number of times circuit has been opened since start of Integration Server. |
Request Count | Number of incoming requests since circuit was opened last. |
