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:
*Closed. The service executes.
*Open. The service does not execute. Instead, depending on the circuit breaker configuration, the service returns an exception or executes an alternative service.
*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.
*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.
watt.server.dashboard.service.responseTime.threshold
This parameter is used to compare and color code the maximum response time of a service. The number you provide denotes a percentage. If the maximum response time of a service exceeds the average response time by the margin given by this parameter, then the maximum response time value is colored red.
Maximum response time > Average response time + (Average response time * wattValue)
where wattValue is the value of the watt.server.dashboard.service.responseTime.threshold server configuration parameter.
If this parameter is set to zero, then no comparison will be made. Other values, such as negative values and decimal values are ignored and the default value of 50% is used.
