The following sections describe the failure conditions for which sentryd monitors the optional Service Assurance process (sacw) and states that the Surveillance feature restarts sacw when it fails.
The sentryd process monitors the optional Service Assurance process (sacw) so that it can be stopped if the OSI process need to be restarted. It is monitored for the following conditions:
An unintentional exit or crash during normal operation
Inability to perform its defined tasks, for example, because it is in an infinite loop
The sentryd does not attempt to restart the Service Assurance process when it fails. The Surveillance feature performs that function. For more information about the Service Assurance process, see “Understanding the Service Assurance Feature”.
