# SNMP String Monitors: General

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 trap 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. 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 | 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: `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 trap is generated when the criteria specified by Notify Match or Notify Differ is satisfied. MBean Attribute: `SNMPStringMonitorMBean.StringToCompare` Changes take effect after you redeploy the module or restart the server.
Notify Differ | Generates a trap if the value of the monitored attribute and the value of String to Compare are different. MBean Attribute: `SNMPStringMonitorMBean.NotifyDiffer` Changes take effect after you redeploy the module or restart the server.
Notify Match | Generates a trap if the value of the monitored attribute and the value of String to Compare are the same. MBean Attribute: `SNMPStringMonitorMBean.NotifyMatch` Changes take effect after you redeploy the module or restart the server.
