Universal Messaging KPIs
You can view the following key performance indicators (KPIs) to monitor the performance of the Universal Messaging servers:
KPI
Description
JVM Memory
Indicates the utilization of JVM memory.
The marginal, critical, and maximum values for this KPI depend on the maximum memory size of the JVM.
*Marginal is 80% of the maximum JVM memory.
*Critical is 95% of the maximum JVM memory.
*Maximum is 100% of the maximum JVM memory.
Fanout Backlog
Indicates the total number of events currently waiting to be processed by the fanout engine. If the fanout backlog is more than the critical value, there is a possibility that the subscribers receive the published events after some delay.
The KPI uses the following marginal, critical, and maximum values:
*Marginal is 80% of the maximum value.
*Critical is 95% of the maximum value.
*Maximum is 100% of the peak value (high-water mark) of fanout backlog. Default is 100.
Queued Tasks
Indicates the total number of tasks in the read, write, and common read/write pools. If the number of read and write tasks queued is more than the critical value, it indicates that the Universal Messaging server is unable to match the speed of the publishers and subscribers.
The KPI uses the following marginal, critical, and maximum values:
*Marginal is 80% of the maximum value.
*Critical is 95% of the maximum value.
*Maximum is 100% of the peak value (high-water mark) of read and write tasks queued. Default is 100.
