Use cases

Additional processing duration information about processed messages is written to the log. A threshold can be configured so that a Warning log entry will be written indicating that a message is still processing. For example, a message should take less then 10 seconds to be processed, if it takes longer a Warning log entry is written while the message is still being processed. Messages that hang an endpoint can now easily be identified. When a message completes processing its total processing duration is written to the log with level Debug but a message that took more then the threshold will also be logged with log level Warning.

Log event examples

Log event written for every completed message:

DEBUG NServiceBus.SimpleMonitoring Message '000526b2-44cd-4d6d-9aa3-a8ad0126e6e6' total processing duration: '0:00:00,1349758'

Log event written for completed messages where the duration exceeds the threshold:

WARN NServiceBus.SimpleMonitoring Message '6625296c-50b1-4f07-ac90-a8ad0127304a' total processing duration (0:00:23,0370282) is larger than the threshold '0:00:15'.

Log event written every interval for each message currently being processed but exceeding the threshold

WARN NServiceBus.SimpleMonitoring Message '6625296c-50b1-4f07-ac90-a8ad0127304a' is already running for '0:00:20,1372179' which is larger than the thresshold '0:00:15'.

Note that the formatting of the log events is different per used logging framework but the message part is the same.


Via Nuget

Install the Nuget package NServiceBus.SimpleMonitoring

Zero configuration and deployment

Alternatively, download the nuget package, extract the DLL and drop-in the DLL in the endpoint installation path and restart the endpoint. Assembly scanning ensures this module will get auto loaded and enabled using default configuration values.


Set the Warning threshold

The default warning threshold is 15 seconds.

The threshold value can only be configured via code or via AppSetting.

Note that is both are used the AppSetting takes precedence.

Via code:


Via AppSetting:

    <add key="NServiceBus/SimpleMonitoring/LongRunningMessages/WarningThresholdInSeconds" value="180"/>

Note that the above snippet will report messages with log level Warning if their processing duration is over 180 seconds (3 minutes).

Show durations for all messages

Message processing durations are always logged with log level Debug however the default NServiceBus log level is Info since version 5. Please set the NServiceBus logging log level to Debug if this is required.
