# SNMP Gauge Monitors: General

Configuration Options Related Tasks Related Topics

Use this page to configure a gauge monitor, which periodically checks the value of an integer or floating-point attribute and generates a trap if the value equals or exceeds a threshold.

#### Configuration Options

Name | Description
--- | ---
Name | The name of this gauge 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 gauge monitor. After you have created a gauge monitor, you cannot change its name. Instead, clone the gauge monitor and provide a new name for the clone. MBean Attribute: `SNMPGaugeMonitorMBean.Name` Changes take effect after you redeploy the module or restart the server.
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.
User Entered MBean Name | User Entered MBean Name.
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.
