The monFlags column in the Self Monitor table is a 32-bit unsigned integer that can specify additional behavioral semantics for the corresponding Self Monitor table row. By default, the Self Monitor table row does the following:
You can set flag bits to alter these defaults. The SystemEDGE agent interprets all flags in hexadecimal (base 16) notation. The following illustration shows the composition of the Self Monitor Table flags field (monFlags).
The flags value consists of three fields:
The following sections explain each flag bit. You can combine these flag values through a logical OR operation.
The following list describes the Self Monitor Table flags:
Disables execution of actions for this entry.
Disables sending of SNMP traps for this entry.
Note: The Self Monitor table only controls sending traps for legacy monitors. For stateful self monitors, state change traps may still occur from the Aggregate State table.
Disables attempts to reinitialize this entry. By default, the agent periodically tries to reinitialize this entry by attempting to query the MIB object it is monitoring. Reinit occurs if query failed
Disables logging of traps for this entry in the sysedge.log file. Setting this bit does not affect sending trap. Disabling event logging is useful when events occur frequently or when a particular entry is used as an agent heartbeat.
Sends continuous monitorEntryNotReady traps for this entry each time the agent attempts to reinitialize monitoring and fails to query the MIB object. The agent's default behavior is to send a single monitorEntryNotReady trap when a MIB object it is monitoring ceases to exist, even when succeeding attempts to reinitialize the entry still fail. Enabling this feature causes the agent to send an additional monitorEntryNotReady trap each time reinitialization fails.
Disables the passing of default arguments to action scripts or programs. SystemEDGE typically passes default action parameters that indicate the trap type, description field, and so on. For more information about action parameters, see Self Monitor Table Action Parameters.
Disables sending of notReady traps for this entry.This includes to not log and to not execute actions for notReady trap.
Sends a monitorClear trap for this entry when the self monitor expression transitions from True to False. This includes to log and to execute actions for the monitorClear trap.
Sends monitor threshold traps or changes the current state only on the Xth consecutive breach. After the Xth breach occurs, the agent sends monitor traps for each subsequent True expression evaluation. If the threshold expression transitions from True to False, the agent begins counting subsequent breaches from zero. This flag also applies to action execution and logging. You can specify the value of X through the flag value field. For an example of this behavior, see Self Monitoring Examples.
Sends up to X consecutive monitor traps, and then sends no more. Enabling this feature puts an upper boundary on the number of consecutive monitor traps and action executions that can occur when a threshold has been exceeded. After the threshold expression transitions from True to False, the agent begins counting subsequent breaches from zero. This flag also applies to action execution and logging. You can specify the value of X through the flag value field. For an example of this behavior, see Self Monitoring Examples.
Aggregates the state of monitors for the same object information (class, instance, attribute) and with the same severity so that they have an AND relation. All connected monitors with the same severity that have this flag set must have breach conditions for the aggregate state to change accordingly.
Several flag bits use a value X for sending traps and executing actions and log. The value X is specified as the high-order 12 bits of the flag field. Flag bits utilizing this field are mutually exclusive.
