At any given time, the state of the endpoint can be one of the following:

State

Description

Active

Endpoint is running and handling requests.

Timeout

Endpoint encountered an error but can still send and receive messages. If it continues to encounter errors, it will be suspended.

Suspended

Endpoint encountered errors and cannot send or receive messages. Incoming messages to a suspended endpoint result in a fault.

OFF

Endpoint is not active. To put an endpoint into the off state, you need to use JMX.

When WSO2 Enterprise Service Bus starts, endpoints are in the "Active" state and ready to handle messages. If the user does not put the endpoint into the OFF state, it will be in the "Active" state until an error occurs.

Name

Default

Description

duration

Miliseconds

60000

Connection timeout interval. If the remote endpoint does not respond in this time, it will be marked as "Timeout."

responseAction

discard, fault,

none

never

none

never

When a response comes to a timed out request, specifies whether to discard it or invoke the fault handler.

If none

 If you select "never", the endpoint remains in the "Active" state.

"MarkForSuspension" Settings

Name

Values

Default

Description

errorCodes

Comma separated list of error codes

101504, 101505

Errors that put the endpoint into the "Timeout" state. If no error codes are specified, the "HTTP Connection Closed" and "HTTP Connection Timeout" errors are considered "Timeout" errors, and all other errors put the endpoint into the "Suspended" state.

retriesBeforeSuspension

Integer

0

In the "Timeout" state this number of requests minus one can be tried and fail before the endpoint is marked as "Suspended". This setting is per endpoint, not per message, so several messages can be tried in parallel and fail and the remaining retries for that endpoint will be reduced.

retryDelay

milliseconds

0

The time to wait between the last retry attempt and the next retry.

errorCodes

Comma separated list of error codes

All the errors except the errors specified in markForSuspension

Errors that send the endpoint into the "Suspended" state.

initialDuration

milliseconds

30000

After an endpoint gets "Suspended," it will wait for this amount of time before trying to send the messages coming to it. All the messages coming during this time period will result in fault sequence activation.

progressionFactor

Integer

1

The endpoint will try to send the messages after the initialDuration. If it still fails, the next duration is calculated as:

Min(current suspension duration * progressionFactor, maximumDuration)

maximumDuration

milliseconds

Long.MAX_VALUE

Upper bound of retry duration.

Sample Configuration:

Code Block
<endpoint name="Sample_First" statistics="enable" >
    <address uri="http://localhost/myendpoint" statistics="enable" trace="disable">
        <timeout>
            <duration>60000</duration>
        </timeout>

        <markForSuspension>
            <errorCodes>101504, 101505</errorCodes>
            <retriesBeforeSuspension>3</retriesBeforeSuspension>
            <retryDelay>1</retryDelay>
        </markForSuspension>

        <suspendOnFailure>
