Fixed In:

Opened: Nov 06, 2014

Severity: 3-Major


External logging of AVR statistics is done by HSL framework, if a message is failed to be sent to the syslog server, then AVR does not log this error.


The logging application will not receive all log entries.


If network is under stress, there is a possibility that the external logging will not be 100% transmitted



Fix Information

AVR is logging about HSL sending error. It is important to notice that it is still not 100% sure that the message will arrive to the destination, since an application level ack does not exist in syslog, but this by definition.
