Configuring dynamic rule tracing

While the cell is running, rule tracing configuration can be changed by using the mcontrol CLI. Following are the controls that influence rule tracing:

• tracerule on|off—Globally enables (on) or disables (off) rule tracing 

• tracerule phasesPhases—Modifies the configuration of which rule phases are enabled for tracing. The Phases value has the same format as the TraceRulePhases parameter. For example:

  mcontrol -n CellName tracerule phases -new,-abstract

  This command disables tracing of all new and abstract rules. 

• tracerule namesNames—Modifies the configuration of which rules are enabled for tracing. The Names value has the same format as the TraceRuleNames parameter. For example:

  mcontrol -n CellName tracerule names problem_rule

  This command enables tracing of the rule named problem_rule (assuming that problem_rule is of a phase that has rule tracing enabled). 

• tracerule ports Ports—Determines which tracing ports are enabled. Ports is a string with the same format as the TraceRulePorts parameter, described on Configuring static rule tracing.

Each time the cell starts, it reverts to the static rule tracing configuration defined in mcell.conf.
