monitoring open http sessions on a jboss server
by Attila Heidrich
Hi,
is there a way to monitor the open sessions of a jboss server?
I see I have some metrics for the http connector, and the requests per
second value is really useful, but we need some more detailed statistics.
It would be the best to have some browser to select the parameters... ;)
for webapp dveelopers it would be such a great benefit!
Afaik, there're some internal values in the jboss server, should I extend
the JBoss plugin to get a value, which isn't got now?

RHQ alert definition template issue
by barry.barnett@wellsfargo.com
Hello,
I have RHQ4.13.1 installed. I'm running 5 RHQ server instances clustered together (each on its own server) with a backend shared Oracle DB.
When I first completed the installation and configuration, the 'Alert Definition Templates' would load when I clicked on the link in the Admin panel of the GUI. Now, after a few months, when I click on the Alert Definition Templates, it simply says 'loading' and never loads. I see this error in the logs:
Caused by: java.lang.RuntimeException: com.datastax.driver.core.exceptions.UnavailableException: Not enough replica available for query at consistency ONE (1 required but only 0 alive)
at org.rhq.cassandra.schema.AbstractManager.getInstalledSchemaVersion(AbstractManager.java:193) [rhq-cassandra-schema-4.13.1.jar:4.13.1]
at org.rhq.cassandra.schema.VersionManager.checkCompatibility(VersionManager.java:266) [rhq-cassandra-schema-4.13.1.jar:4.13.1]
... 50 more
Any idea what I need to do to correct this?
