Configuration Options     Related Tasks     Related Topics

Use this page to configure a string monitor, which periodically checks the value of a string attribute and generates a notification if the value is equal to or different from another specified string.

Configuration Options

Name	Description
Name	The name of this string 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 monitor, you cannot change its name. Instead, delete it and create a new one. MBean Attribute: SNMPStringMonitorMBean.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: 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=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: SNMPStringMonitorMBean.MonitoredMBeanName Changes take effect after you redeploy the module or restart the server.
User Entered MBean Name	The short name of an MBean instance. Requires you to select User Entered MBean Name in the Monitored MBean Name list. Enter a name in this field if you want to monitor an MBean instance that is not currently active. You provide the short name for an MBean when you create the associated resource.
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
