# SNMP Gauge Monitors

Column Display Related Tasks Related Topics

A gauge monitor indicates whether an attribute is operating within a specific range.

This page summarizes the gauge monitors that have been configured in the current WebLogic Server domain.

The monitor periodically polls an attribute whose value is an integer or floating-point and compares the attribute value with a high and a low threshold that you define. It generates a trap if the attribute value is equal to or exceeds the high or low threshold.

#### Column Display

You can show fewer or additional data points on this page by expanding Customize this table and modifying the Column Display list. Each data point displays in its own table column.

The following table lists all of the data points that you can display in columns on this page.

Name | Description
--- | ---
Name | The name that you provided when you created the monitor.
Monitored MBean Type | The MBean type that defines the attribute you want to monitor. Do not include the `MBean` suffix. For example, `ServerRuntime`. MBean Attribute: `SNMPGaugeMonitorMBean.MonitoredMBeanType` Changes take effect after you redeploy the module or restart the server.
Monitored MBean Name | The name of the MBean instance that you want to monitor. If you leave the name undefined, WebLogic Server monitors all instances of the MBean type that you specify in Monitored MBean Type. Do not enter the full JMX object name of the MBean instance. Instead, enter only the value of the object name's `Name=name` name-value pair. To create unique MBean object names, WebLogic Server encodes several name-value pairs into each object name. One of these pairs is `Name=name`. For example: `"MedRec:Name=MedRecServer, Type=ServerRuntime"` In the previous example, specify `MedRecServer` as the name of the MBean instance. MBean Attribute: `SNMPGaugeMonitorMBean.MonitoredMBeanName` Changes take effect after you redeploy the module or restart the server.
Monitored Attribute Name | The name of an MBean attribute to monitor. This attribute must be in the WebLogic Server MIB. MBean Attribute: `SNMPGaugeMonitorMBean.MonitoredAttributeName` Changes take effect after you redeploy the module or restart the server.
Polling Interval | The frequency (in seconds) that WebLogic Server checks the attribute value. MBean Attribute: `SNMPGaugeMonitorMBean.PollingInterval` Minimum value: `1` Maximum value: `65535` Changes take effect after you redeploy the module or restart the server.
Threshold High | The high threshold at which a trap should be generated. A trap is generated if the monitored value is equal to or greater than this value. MBean Attribute: `SNMPGaugeMonitorMBean.ThresholdHigh` Changes take effect after you redeploy the module or restart the server.
Threshold Low | The low threshold at which a trap should be generated. A trap is generated if the monitored value is less than or equal to this value. MBean Attribute: `SNMPGaugeMonitorMBean.ThresholdLow` Changes take effect after you redeploy the module or restart the server.
