SNMP Agents: Configuration: Gauge Monitors
Column Display Related Tasks Related Topics
A gauge monitor indicates whether an attribute is operating within a specific range.
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 notification 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.
If you target SNMP agents to individual Managed Servers, make sure that the MBean instance you specify is active on the Managed Servers you have targeted. For example, if you specify
MServer1
as the name of a ServerRuntimeMBean instance, this monitor will only function if you target an SNMP agent either to the Administration Server or to a Managed Server namedMServer1
.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 isName=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 notification should be generated. A notification is generated the first time the monitored value is equal to or greater than this value.
Subsequent crossings of the high threshold value do not cause additional notifications unless the attribute value becomes equal to or less than the low threshold value.
MBean Attribute:
SNMPGaugeMonitorMBean.ThresholdHigh
Threshold Low The low threshold at which a notification should be generated. A notification is generated the first time the monitored value is less than or equal to this value.
Subsequent crossings of the low threshold value do not cause additional notifications unless the attribute value becomes equal to or greater than the high threshold value.
MBean Attribute:
SNMPGaugeMonitorMBean.ThresholdLow
