The monitor directive lets you add self monitor entries to the Self Monitor table directly in the sysedge.cf file. The arguments represent columns in the Self Monitor table.
Add a line to the sysedge.cf file in the agent data directory using the syntax described below, save the file, and restart the agent for the change to take effect.
Use the monitor directive to add entries to the Self Monitor table as follows:
(1) monitor oid oid index flags interval stype oper thresh ['descr' ['action' [supIndex]]]
(2) monitor oid oid index flags interval stype oper thresh ['descr' ['action' ['objClass' 'objInst' 'objAttr' severity]]]
(3) monitor table inst attr index flags interval stype oper thresh ['descr' ['action' [supIndex]]]
(4) monitor table inst attr index flags interval stype oper thresh ['descr' ['action' ['objClass' 'objInst' 'objAttr' severity]]]
Specifies the OID to monitor. You can specify the OID using the complete dotted-decimal value (for example, 1.3.6.1.2.1.25.1.5.0) or the symbolic MIB name (for example, hrSystemNumUsers.0). Either way, you must specify the object instance, which is typically zero for non-tabular MIB variables or corresponds to the specific instance of an attribute that belongs to a MIB table.
Examples:
Specifies the tableEntry, instance, and attribute name of the object to monitor. If the attribute has no instance, enter '' for the instance property.
Examples:
For more information, see Reverse OID Lookup.
Specifies the row (index) of the monitor table to use for this entry. Each row in the table is uniquely identified by an index number. Rows 1 through 10 are reserved for internal use by the agent, so the index value must be greater than 10 and unique across the table.
Specifies any additional behavioral instructions for this entry using a hexadecimal flags value (for example, 0x00000001). For more information about available flags, see Self Monitor Table Flags.
Specifies how often in seconds the monitoring should occur. For example, the value 30 instructs the agent to monitor this entry every 30 seconds. The value must be a minimum of 30 and a multiple of 30 seconds.
Specifies whether the agent should sample the attributes's absolute value (absoluteValue) or take the difference between successive samples (deltaValue). Use deltaValue to monitor counter variables for rate of change, and use absoluteValue to monitor gauges for exact value.
Specifies the Boolean operator for evaluating the current entry value against the provided threshold value.
Valid values for the operator are as follows:
Default: nop
Specifies the integer threshold value to which the current value of the monitored attribute is compared using the specified operator.
Specifies an arbitrary description (0 to 512 characters in length) of the table entry.
Specifies a command (0 to 2048 characters in length), including the full path and any parameters, to run when the threshold condition is met and the agent sends a threshold breach trap (legacy monitors) or state change trap (stateful monitors). For stateful self monitors, the command does not run if a threshold breach does not result in an object state change. If the string is empty, the agent performs no action for this entry.
Note: You can change the default settings when the agent performs actions. For more information, see the chapter "Agent Configuration."
Specifies the table index that acts as a parent or overriding partner to this entry. Valid values are existing or future SystemEDGE monitor indexes (a positive integer value). The default is zero (0), indicating default behavior.
Note that usage of the object state model (entering a severity other than none) obsoletes and disables this functionality.
Defines the object class of the monitored MIB object for use with the object state management model. The agent uses the sysedge.oid file to assign a default value. A class name can be used to specify a monitored object table. If SystemEDGE does not determine an existing table with the specified name, SystemEDGE creates a class. The class specifies the monitoring object identifier (SNMP OID) and can be referenced for aggregation purposes.
Important! The newly created reference is valid only if the monitoring entry resolves to an existing SNMP OID.
Specifies the object instance of the monitored object for use with the state management model. Define a value for this property (with objClass and objAttr) for creating a managed object that aggregates all entries with the same values. The agent uses the sysedge.oid file to assign a default value for tabular objects based on a specific attribute value and assigns null as the default for non-tabular objects.
Specifies the object attribute for use with the state management model. Define a value for this property (with objClass and objInst) for creating a manged object that aggregates all entries with the same values. The agent uses the sysedge.oid file to assign a default value that corresponds to the MIB attribute name.
Default: MIB attribute name
Specifies the severity to use for the object state management model. This value defines the state to assign to the entry when a threshold breach occurs. Valid values are as follows:
A value of none creates a legacy monitor, which excludes the entry from the object state management model.
Default: none
