Perform Java Actions

Introduction: 

This section is common to all the editions of IT360 - Professional Edition, Enterprise Edition [Probes Only] and MSP Edition [Probes Only].

This action performs Java actions, such as generating thread dump, heap dump or garbage collection, in the event of an Alarm.

Steps to Create a Java Action:

To create a Java action, follow the steps given below;

1. Go to 'Admin -> Servers & Applications -> Actions'.

2. Click Add New under Java Thread Dump, or Create Java Action link under the heading: Create Java Action(s).

Now, specify the following details, in the Create Action : Java Thread Dump page, displayed;

3. Select the Java Heap Dump/Thread Dump/GC option from the Select Action Type menu.

4. Enter the Display Name of the action.

5. Choose the Action Type to be performed in the event of an alarm. You can choose either 'Thread Dump', 'Heap Dump' or 'Perform GC' option.

   • If you choose the 'Thread Dump' option, specify the Number of thread dumps, to be performed, and the Delay between thread dumps, in seconds.

   • If you choose the 'Heap Dump' option, specify the Number of heap dumps, to be performed, and the Delay between heap dumps, in seconds.

   • If you choose the 'Perform GC' option, specify the Number of GCs, to be performed, and the Delay between GCs, in seconds.

6. Select the email action, to be associated with this Java action, by selecting an email action from the Associate Email Action dropdown. You can do either of the following;

• Select an existing email action from the drop-down.

• Create a new email action, by clicking the 'New Action' link. You need to enter the desired email id in the textbox displayed, and click Save.

7. Select Target JRE for this action from the drop-down box. The available options include Auto-select JRE, All JREs in the selected monitor group, Specific host and Specific JRE;

• If you select Auto-select JRE, IT360 will automatically detect and trigger the Java actions, based on the associated monitor. For example, if the action is associated with a host, this will trigger thread dump for the JREs, available in the host. If the action is associated with a Tomcat / JRE monitor, this will trigger the thread dump for the JREs, present in the host of Tomcat server or JRE.

• If you select All JREs in the selected monitor group, this will trigger java actions for all the JREs, present in that monitor group.

• If you select Specific host option, this will trigger java actions for all the JREs, present in the selected host.

• Selecting a Specific JRE will trigger java actions for that JRE.
