You can configure monitoring for a server by setting the properties on the Monitors tab. You can also tune listener performance by configuring these properties on the listener’s Performance tab.
Maximum Response Time The
maximum response time (in milliseconds) before the number of active
threads is decreased. To specify an unlimited response time, enter -1 (the
default). The configuration property name is maximumResponseTime.
Performance Thread Monitor The thread monitor used for performance monitoring; the default is “performance.” The configuration property name is performanceThreadMonitor. See “Monitoring threads”.
Maximum Virtual Memory The maximum amount of virtual memory that the server process can use, specified in bytes. The configuration property name is maximumVirtualMemory.
Critical Memory Limit (%) The
percentage of memory that must be in use before the condition is
considered critical and no further requests are accepted. To specify
no limit, enter -1; the default is
90. The configuration property name is criticalMemLimit.
Memory Limit for Alarm (%) The percentage of memory that must be in use before a warning is logged; the default, -1, indicates that there is no limit. The configuration property is alarmMemLimit.
Critical JVM Memory Limit (%) The percentage of JVM memory that can be in use before the condition is considered critical and no further requests are accepted; -1, indicates that there is no limit. The default value is 90. The configuration property name is criticalJavaMemLimit.
JVM Memory Limit for Alarm The percentage of JVM memory that can be in use before a warning is logged; -1, indicates that there is no limit. The configuration property name is alarmJavaMemLimit.
Alarm Log Interval The frequency at which alarm conditions are logged, specified in seconds; the default is 30. The configuration property name is alarmLogInterval.
Memory Thread Monitor The thread monitor used for memory monitoring; the default is “memory.” The configuration property name is memoryThreadMonitor. See “Monitoring threads”.
