Rule sets for error handling
Monitoring
Error handling 8
Several rule sets for error handling are provided by default on the appliance. They are nested in the
Default error handler rule set. This section describes these rule sets.
For general information on understanding and handling rules, see Rules and rule sets.
Long Running Connections
This nested error handling rule set keeps connections alive when a proxy module error occurs.
Nested error handling rule set — Long Running Connections
Criteria — Error.ID equals 20000
The rule set criteria specifies that the rule set applies when the value of the Error.ID property is 20000,
which indicates a malfunction of the proxy module.
The rule set contains the following rule:
Keep connection always alive
Always –> Stop Cycle
When the rule is executed, it stops the current processing cycle. The rule is always executed when
the criteria of its rule set is matched. Stopping the processing cycle prevents the connection from
being closed in the course of further rule processing.
Note: This rule is not enabled by default.
Monitoring (rule set)
This nested error handling rule set handles measures taken when an incident occurs that involves the
appliance system.
Nested error handling rule set — Monitoring
Criteria — Incident.ID equals 5
The rule set criteria specifies that the rule set applies when the value of the Incident.ID property is 5,
which indicates an incident that involves the appliance system.
The following rule sets are nested within this rule set:
• Check CPU Overload
• Check Cache Partition
• Check Request Overload
