Maven artifacts for RHQ 4.0.1
by Andreas Veithen 11 Jul '11

11 Jul '11

Hi, I'm in the process of upgrading some custom RHQ plugins from 3.0.0 to 4.0.1. Previously I used the following Maven repository in my build: https://repository.jboss.org/nexus/content/groups/public/ I noticed that this repository doesn't contain the artifacts for 4.0.0 and 4.0.1 (the latest version is 4.0.0.B02). Is RHQ now using a different Maven repository? Andreas

cannot update plugin operation
by Bala Nair 27 Jun '11

without first deleting operation history. I get the following error in the server log: 2011-06-21 09:25:43,988 INFO [org.rhq.enterprise.server.core.plugin.ProductPluginDeployer] Deploying [1] new or updated agent plugins: [quoteserver] 2011-06-21 09:25:45,007 WARN [org.hibernate.util.JDBCExceptionReporter] SQL Error: 0, SQLState: 23503 2011-06-21 09:25:45,007 ERROR [org.hibernate.util.JDBCExceptionReporter] Batch entry 0 delete from RHQ_OPERATION_DEF where ID='10301' was aborted. Call getNextException to see the cause. 2011-06-21 09:25:45,007 WARN [org.hibernate.util.JDBCExceptionReporter] SQL Error: 0, SQLState: 23503 2011-06-21 09:25:45,007 ERROR [org.hibernate.util.JDBCExceptionReporter] ERROR: update or delete on table "rhq_operation_def" violates foreign key constraint "rhq_operation_history_operation_def_id_fkey" on table "rhq_operation_history" Detail: Key (id)=(10301) is still referenced from table "rhq_operation_history". This makes updating plugins somewhat problematic. We are bundling our service specific plugins into rpms for deployment and this behavior would break updates via rpm. Is there any way around this?

Migration from RHQ 3.0 to RHQ 4.x
by Aurelio Calegari 23 Jun '11

23 Jun '11

Hello, We currently have a number of systems monitored with RHQ 3, and we'd like to promote a migration to RHQ 4, but I could not find enough documentation in RHQ site as for the migration to the new version. Is there a how to or we can simply install on top of the existing database with existing metrics?

problem installing a custom JMX plugin when the defaultInterval is < 30000
by BARTH Michael 17 Jun '11

17 Jun '11

Hello All, I am trying to get some JMX metrics into RHQ. All works fine but I have some trouble installing the JMX plugin whith a defaultInterval lower than 30000 (a custom-jmx-plugin-1.0-SNAPSHOT.jar.fixme is left in the update directory when clicking on "scan for updates" in RHQ's Administration tab). A JMX plugin with the following metrics inside deploys: <metric property="ServiceTime" displayName="Service time" defaultOn="true" displayType="summary" defaultInterval="30000" description="Time between the first and request and the last response."/> <metric property="ServiceTime" displayName="Service time" defaultOn="true" displayType="summary" defaultInterval="40000" description="Time between the first and request and the last response."/> A JMX plugin with the following metrics inside does not deploy: <metric property="ServiceTime" displayName="Service time" defaultOn="true" displayType="summary" defaultInterval="20000" description="Time between the first and request and the last response."/> Any help on this would be highly appreciated. Thank, Michael

bundles to non-platforms
by John Mazzitelli 15 Jun '11

15 Jun '11

I need to ask a question of those folks using the bundle/provisioning feature in RHQ. Is anyone using the feature where you can have a *MIXED* group of platforms and deploy a bundle via a single destination to that mixed group. When I say "mixed" group of platforms, I mean you have a group of N platforms where those N platforms are of different types of machines - like Linux + Windows machines or HP-UX + Linux or some combination like that. Or, do you only ever use a group with N platforms of the same type (like all Linux machines, or all Windows machines). In my implementation of https://bugzilla.redhat.com/show_bug.cgi?id=644328 (as of right now) that feature will no longer be possible so I need to know if I should worry about this. If you want to deploy a bundle to a group of linux boxes AND a group of windows boxes, in the new code, you'd have to define two different destinations (one to the group of linux and one to the group of windows). That probably sounds like something you'd be doing anyway, but the fact is it is possible today to deploy a bundle to a single destination that goes to a heterogeneous group of platforms and I need to know if anyone is actually doing this and cares to keep that kind of functionality.

RHQ Documentation Updates
by Stefan Negrea 06 Jun '11

06 Jun '11

Hello All, I updated all the screenshots from RHQ user documentation wiki (http://www.rhq-project.org/display/JOPR2/Home) with news ones taken from RHQ 4.0. In some cases, I had to slightly update the text for the screenshot because of changes in UI and/or functionality. If by any chance I missed something, please let me know and I will be more than glad to update the page/s. The new RHQ UI is eye-candy :) Thank you, Stefan Negrea Software Engineer

Custom UI?
by Prashant Shewale 06 Jun '11

06 Jun '11

Hi, We are in the process of developing new centralized management system for our product. While doing research related to that I came across RHQ project and am very happy to see that it has all the features that we want like inventory, monitoring, configuration, operations, events etc. I am thinking of using RHQ as a base for our management application. But we are interested in building Custom UI as per customer requirement. So can you please let me know is it possible to have RHQ server as base but to have different UI for that? Are there any APIs available to build own UI? If it is not possible to have custom UI, can I modify exiting UI to add information related to our product etc.? Thanks for such a wonderful management platform. Regards, Prashant
