Creating a WebLogic SNMP monitor offloads polling of WebLogic Server resources from SNMP managers to one or more WebLogic Server SNMP agents.
WebLogic SNMP monitors poll WebLogic Server configuration and runtime attributes of resources at a specified interval to check for the occurrence of conditions or the crossing of thresholds. When a monitor detects the specified condition, the SNMP agent in which the monitor is running sends a notification to each SNMP manager for which you have configured a trap destination.
You can create the following types of SNMP monitors:
A gauge 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.
A counter monitor periodically polls an attribute whose value is an integer and compares the attribute value with a high threshold that you define. It generates a notification if the attribute value equals or exceeds the high threshold. You can also configure an offset or modulus, which increases or decreases the threshold each time the threshold is crossed.
