Dynamically adding new metrics
by Al Amyot 21 Dec '11

21 Dec '11

Is there any way for a Script plugin to "find" and add new metrics? Normally, these are hardcoded in the xml configuration file of course. For example, let's say the script queries a database "where name like 'metric%'" Then for each returned row, returns a value for 'metric1', metric2' etc.. As the returned list changes, new metric collection would begin and deprecated ones might stop.

Defining alerts across multiple resources
by Al Amyot 21 Dec '11

21 Dec '11

If I understand alert definitions correctly, they can only test availability, traits and metrics within one resource. This means that I cannot test for server1=DOWN AND server2=DOWN as a simple example. Is this correct? If so, has any consideration been given to making the alerting system more 'global' in scope?

RHQ 4.2 and JBoss AS 6.1
by Fernando Lozano 20 Dec '11

20 Dec '11

Hi there, Is RHQ 4.2 supposed to be able to manage JBoss AS 6.1 instances ? Here I have two as 6.1 instances on the same machine, one with a password-protected jmx invoker, other is a plain "default" instance running as ports-01. For the first one, the agent discovers only resources (datasources, connection factories and jboss web) and the Service Binding Manager. For the second one, it also discovers JVM and mod_cluster (but with a problem icon "i"), besides resources. The agent doesn't for any of them apps soch as ROOT.war. I already tried forcing a manual discovery on the agent. Actually it was necessary after I updated the connection setttings for the first instance, as its JMX was password-protected. But this made discovery find only resources, nothing else. []s, Fernando Lozano

RHQ Agent disable automatic discovery
by Alan Evans 14 Dec '11

14 Dec '11

Is it possible to tell the RHQ agent not to do discovery on startup and then at intervals later? I have seen the following properties but I would like to prevent automatic discovery all together. rhq.agent.plugins.server-discovery.* rhq.agent.plugins.service-discovery.* rhq.agent.plugins.content-discovery.* I have run up against the bug found in the following links where RHQ calls an API in JBoss that triggers apps to be undeployed and re-deployed. This is problematic in general but even more for the app my servers are running. But I would like to let RHQ continue to collect metrics and availability from my JBoss instances. https://bugzilla.redhat.com/show_bug.cgi?id=744803 https://issues.jboss.org/browse/JBPAPP-7545 Regards, -Alan

Import group definitions
by Romain Pelisse 13 Dec '11

13 Dec '11

Hi all, I'm working a java tool to export RHQ configuration and import in a new instance - which should help migrating instance between version and/or databases. I managed to export group definition, by tricking a little bit the Remote API (2.4.2): resources = getResourceGroupManager().findResourceGroupsByCriteria(baseRemote.getSubject(), criteria); for ( ResourceGroup resource : resources ) { definitions.add(resource.getGroupDefinition()); } However, I'm pretty much stuck right now, when it comes to importing those group. I've tried to "pass them along" with a dummy group definition... ResourceGroup resGroup = new ResourceGroup("dummy2"); for ( GroupDefinition groupDefinition : groupDefinitions ) resGroup.setGroupDefinition(groupDefinition); ... but it failed as Hibernate is complaining (rightfullly) that those entities are transient... Any proper way to do this ? Would it be difficult to change RHQ code to allow that ? If so, I'll be happy to be pointed to the right direction... Thanks a lot ! -- Romain PELISSE, *"The trouble with having an open mind, of course, is that people will insist on coming along and trying to put things in it" -- Terry Pratchett* http://belaran.eu/wordpress/belaran

Suggestions for PIQL processor/process resource/alert engine
by Alan Evans 13 Dec '11

13 Dec '11

Excuse my recent SPAM. I really dig RHQ, I think it has a lot of potential but there are few things I would like it to do. Ok on to my suggestions. PIQL: -- A way to select a process based on user, and group attributes? user, effective user, login user, group, effective group, login group and by name or uid/gid? maybe: process|user|foo process|uid|500 process|group|foo process|gid|500 process|euser|bar process|luid|500 Process resource: -- A way to return a number of processes matching a PIQL as a trait? Or maybe a trait for number of processes that match? This way an alert could be made for num process > = < some number. I.e. we have a check that looks to make sure there are not more than a certain number of java processes running. Otherwise it indicates that batch jobs are not completing. -- What about returning information that could be retrieved using uname as traits like max open file descriptors, max processes etc Alert Engine: -- The ability to compare one attribute to another or an attribute to a trait? Or a percentage of trait? Alert when open files > 90% max open files Alert when Java Heap > 90% max heap size -- Perhaps a way of defining recovery thresholds without having to define recovery alerts. Maybe wizard to build a recovery alert that is created under the hood but hidden from the alert definition view. Maybe like having the conditions tab have a "recovery conditions" tab and "recovery damping" or recovery tab with "conditions" and "dapming" subtabs? It is cumbersome to have to create a recovery alert and then its associated alert, or create an alert then its recovery alert then go edit the original again to assign its recovery alert. (If that makes sense...) I would love to hear other people's thoughts and whether or not these ideas might be useful others. Regards, -Alan

Add process resource to multiple platforms
by Alan Evans 13 Dec '11

13 Dec '11

If I wanted to add a process resource to multiple platforms what is the best way to go about doing that? Is there a method I can use with groups to do it? Is there a resource template or something I can use? Can a simple plugin be written (i.e. no java, just descriptor) to create these resources? (This would presumably let me be able to customize the name of the resource, name = "Backup Daemon" instead of parsing it from <piql>process|basename|match=nsrexecd</piql>) I am looking for a quick way to duplicate some of the monitors we have going in Nagios that just look for processes to be running. This way I can create avalibility alerts w/ RHQ instead of Nagios. Sure I could use the nagios plugin but a more native way seems more appealing. Thoughts? Regards, -Alan

Export and Import Alert/Drift Definitions
by Alan Evans 13 Dec '11

13 Dec '11

Is it possible to import/export alert or drift definitions? I created a few items under JBossAS Server from the JBossAS plugin but meant for them to be in the JBossAS5 plugin. Perhaps that is another request, to differentiate the RHQ JBossAS Server plugin from the generic JBossAS 5 Server plugin. Regards, -Alan

Suggestion - JBossAS add process resource to JBossAS Server resource
by Alan Evans 13 Dec '11

13 Dec '11

Would it be possible to expose a process resource as part of a JBossAS server or maybe the JBossAS JVM Object instead of having to add a process resource to a platform? It would be useful to collect that info and setup alert templates as part of the JBossAS Server template without having to rely on piql or pid file to add the process resource to a platform. Regards, -Alan
