SNMP Agents: Configuration: String Monitors

Column Display     Related Tasks     Related Topics

A string monitor periodically polls an attribute whose value is a string and generates a notification if the attribute value matches a string that you specify. Alternatively, you can specify that the monitor generates a notification if the attribute value does not match your string.

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 of

The name that you specified 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:
SNMPStringMonitorMBean.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 named MServer1.

Do not enter the full JMX object name of the MBean instance. Instead, enter only the value of the object name's Name of=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 of=name. For example:
"MedRec:Name=MedRecServer,
Type=ServerRuntime"

In the previous example, specify MedRecServer as the name of the MBean instance.

MBean Attribute:
SNMPStringMonitorMBean.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:
SNMPStringMonitorMBean.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:
SNMPStringMonitorMBean.PollingInterval

Minimum value: 1

Maximum value: 65535

Changes take effect after you redeploy the module or restart the server.

String to Compare

The string against which the value of the monitored attribute will be compared.

A notification is generated when the criteria specified by Notify Match or Notify Differ is satisfied.

MBean Attribute:
SNMPStringMonitorMBean.StringToCompare

Notify Differ

Generates a notification if the value of the monitored attribute and the value of String to Compare are different.

MBean Attribute:
SNMPStringMonitorMBean.NotifyDiffer

Notify Match

Generates a notification if the value of the monitored attribute and the value of String to Compare are the same.

MBean Attribute:
SNMPStringMonitorMBean.NotifyMatch
