[Hawkular-dev] Is there the feature to provide timegap between ripple restart of WildFly(JBoss EAP) cluster in Hawkular?

[Michael Burman]

Hi,

While you can't find this out of the box in the UI of RHQ/JON, this is easily doable with the RHQ-CLI interface. If you take a look at the samples directory and deploy-to-restart-JBAS.js (or jbossas.js), you can find function function _restartAS7(group) which uses _runOperationSequentially(group, operationName, operationConfig) method. This restarts in sequential order all the AS instances and waits for up to 60 seconds. 

To modify the behavior to do one instance at a time and wait for it to finish and abort if it fails, create a loop around the group object (to find single instance ids) in the _runOperationSequantially, change GroupOperation to single reosurce operation and keep rest of the process intact. That should do all the things you need.

So using either of those scripts as a base provides you the functionality you're looking for. While it's not currently modified to work with Wildfly, that one also is quite simple to add (the resource names / groups are the only things that should need changing).

Hi all~, 

Is there the feature to provide timegap between ripple restart of WildFly(JBoss EAP) cluster in Hawkular? 
If there is no feature, I'm curious there is a roadmap for this feature. 
Actually, this kind of feature is useful in a production environment. 

I've already checked RHQ(JON) however there is no for ripple restart. 
RHQ(JON) provides below in restart operation page of Group menu. 
1. "Execute: in the order specified below 
2. "Halt on Failure?" 


Thanks in advance.
