Description
This template monitors the live threads, number of threads created, maximum heap and non-heap memory, used heap and non-heap memory, allocated heap and non-heap size and it also gives the count of passivated, persisted and rejected sessions. It is applicable for the devices containing Glassfish application.
Prerequisites
Java must be installed on the device.
How to Apply: For Glassfish we have Instance Based Monitoring or Component Discovery Monitoring . In order to do that, we should add the following custom parameter:
application.component.name : session
Create different monitors for different components in Instance based monitoring.
Only one component is allowed per monitor in Instance based monitoring.
We have three different types of Component Discovery Monitoring. They are:
For a single component :
ALL: ALL your instances will be monitored.
Expression: The Instance Names that match the expression will be monitored.
Manual Selection: With this option, you can select the desired instances while applying templates to the device.
Metric Parameters
| Parameter | Description |
|---|---|
| Frequency | Warning Threshold | If the metric value satisfies the condition defined along with Warning Threshold value, then a notification is sent to the user. |
| Critical Threshold | If the metric value satisfies the condition defined along with Critical Threshold value, then a notification is sent to the user. |
| Alert | The alert value can be set to either Yes or No. If it is Yes, then an alert message is sent to the user. |
