## Overview

Use this tab to configure Counter Monitors, which periodically check the value of an integer attribute and generate a trap when the value exceeds a threshold.

You can also configure a Counter Monitor to increase the threshold by an offset value after it sends a trap.

Table 335-1

Attribute Label | Description | Value Constraints
--- | --- | ---
Name | The name of this counter monitor. Each monitor within a domain must have a unique name. The name displays in the Administration Console, and if you use WebLogic Server command-line utilities or APIs, you use this name to identify the string monitor. After you have created a counter monitor, you cannot change its name. Instead, clone the counter monitor and provide a new name for the clone. For more information, refer to Cloning Configuration Objects. MBean: `weblogic.management. configuration. SNMPCounterMonitorMBean` Attribute: `Name` |
Monitored MBean Type | The MBean type that defines the attribute you want to monitor. For more information, refer to Determining the Names of Other Attributes. MBean: `weblogic.management. configuration. SNMPCounterMonitorMBean` Attribute: `MonitoredMBeanType` |
Monitored MBean Name | The name of the MBean instance that you want to monitor. If you leave this field empty, WebLogic Server monitors all instances of the MBean type that you specify in Monitored MBean Type. For more information, refer to Determining the Names of Other Attributes. MBean: `weblogic.management. configuration. SNMPGaugeMonitorMBean` Attribute: `MonitoredMBeanName` |
Monitored Attribute Name | The name of an attribute to monitor. For more information, refer to Determining the Names of Other Attributes. MBean: `weblogic.management. configuration. SNMPCounterMonitorMBean` Attribute: `MonitoredAttributeName` |
Polling Interval | The frequency (in seconds) that WebLogic Server checks the attribute value. MBean: `weblogic.management. configuration. SNMPCounterMonitorMBean` Attribute: `PollingInterval` | Units: seconds Minimum: 1 Maximum: 65535
Threshold | Specifies a value that triggers the Counter Monitor to generate a trap. The Counter Monitor generates a trap each time it polls the value and determines that the value has transitioned from below the threshold to at or above the threshold. While the value remains at or above the threshold, the Counter Monitor does not generate additional traps. MBean: `weblogic.management. configuration. SNMPCounterMonitorMBean` Attribute: `Threshold` | Minimum: 0
Offset | Specifies an integer value to be added to the threshold if the threshold is crossed. For example, if you set Threshold to 1000 and Offset to 2000, when the observed attribute exceeds 1000, the Counter Monitor sends a notification and increases the threshold to 3000. When the observed attribute exceeds 3000, the Counter Monitor sends a notification and increases the threshold again to 5000. The threshold can increase up to a maximum specified by the Modulus attribute. MBean: `weblogic.management. configuration. SNMPCounterMonitorMBean` Attribute: `Offset` | Minimum: 0
Modulus | Specifies the maximum value for the threshold. You can specify an offset that causes the threshold to increase. When the threshold reaches the value specified by the Modulus, the threshold is returned to its original value before any offsets were applied. For example, if the original threshold is set to 1000 and the modulus is set to 5000, when the threshold exceeds 5000, the monitor sends a notification and resets the threshold to 1000. If you specify 0, the Counter Monitor does not use the modulus and the threshold value can grow indefinitely. MBean: `weblogic.management. configuration. SNMPCounterMonitorMBean` Attribute: `Modulus` | Minimum: 0
