Add a trait and a respective plugin config property.

Gathering the trait data would issue a "select 1 from dual" or equivalent that was given in the above 
plugin-config-property.


[09:08:10] <kmaslowski> can I monitor oracle database availability (datasources in JBoss) from RHQ?
[09:13:52] <lkrejci> kmaslowski: i think datasources have "Test Connection" operation that you could use
[09:14:13] <kmaslowski> something like "select 1 from dual" to check if database is available
[09:14:27] <kmaslowski> but can I create situation to it?
[09:15:12] <kmaslowski> i don't want to click test database on all my datasources on every minute :-)
[09:15:34] <lkrejci> kmaslowski: you can create a CLI script for that
[09:16:09] <kmaslowski> separate script for every datasource?
[09:16:36] <lkrejci> kmaslowski: no, 1 script that would look for all your datasources, execute the operation on each and write some report out
[09:16:48] <lkrejci> you could schedule a cron job for that
[09:17:12] <kmaslowski> heh so I can't do that from rhq
[09:18:17] <lkrejci> kmaslowski: or I think you can create a group of all your datasources in RHQ UI and then run an operation on them
[09:18:52] <kmaslowski> I will try to do this
[09:39:20] <pilhuhn> Yeah, we could create a trait, that executes the respective "select 1 from dual" as metric taking
[09:42:51] <kmaslowski> yes:-) it would be great:-)
