Unable to delete a resource
by Al Amyot
On the platform Inventory list, there are no checkboxes before each
resource which makes it impossible to use the Delete button. Is this the
correct way to delete a resource?
See the attached screen shot. This was rendered using Firefox 3.6.10 and
also appears this way on IE7 (IE7 does not properly display scroll bars
and so is unusable for RHQ)

deploying a custom plugin in HA environment
by Bala Nair
Maybe this is a stupid question but when I'm deploying a new custom
plugin in an HA environment do I have to deploy it to each server in the
HA cloud? I couldn't find anything about this scenario on the wiki,
except the note that the rhq servers have no contact with each other
except through the db.

Availability collection interval
by Cesar William
How can I change the "Availability" collection interval for a service? I can
change other metrics in "MONITOR > SCHEDULES" but I can't find the
Availability to change the collection interval.

graphing Script plugin metrics
by Al Amyot
I have customized the Script plugin by adding several metrics. These
successfully display on the Monitor tab under Tables but do not display
under Graphs.
Shouldn't all metrics enabled on the Monitor tab under Schedules also be
graphed? Is this ability determined by the metrics attributes? Below is
an example of the metric definition:
<metric property="{-i MB01 -m read}|"
dataType="measurement"
displayName="MB01 Messages read"
description="Number of messages read by MB01 msgreader"
defaultOn="true"
units="none"
defaultInterval="300000"
displayType="summary"
category="throughput"
measurementType="trendsup"
/>

MySQL Connections
by JAVIER MANSO PEÑA
Hi
I'm having a problem with RHQ and MySQL plugin. As RHQ monitors MySQL, the number of connection in MySQL grow. It happens until MySQL max connections is reached. Then MySQL doesn't accept more connection.
How can I avoid this growth of connections in MySQL?
Best regards,

Fwd: can't get ha failover to work
by John Mazzitelli
[I'm sending this to the rhq-users list - it is more appropriate there -
the rhq-devel list is for developers of the RHQ codebase]
> First why is it trying to fail over to localhost instead of server B
> and second why the connection refused error? There is no rhq server
> on this agent box to refuse a connection.
I suspect that this is because your server B might not have its public
endpoint declared correctly. Go to Administration>Servers and look at
Server B - what is its public endpoint address? Make sure it is correct.
On your agents, what do the failover lists look like? I suspect you will
see "127.0.0.1" in the failover list, as opposed to the server B host/IP
you expect.
Read this as background:

We're trying to set up an rhq HA cloud with 2 servers and 4 agents and
we're having a problem getting the agents to failover to the second
server. When we first start up everything all the agents are connected
to one server (call it server A) with the other server (server B) not
connected to any agents. The failover list on the agent side showing 2
entries (server B and server A in that order). We go to the HA servers
page in the gui and see both servers are in NORMAL mode with server A
having an agent count of 4 and server B a count of 0. There are no
affinity groups. We then set server A to MAINTENANCE mode and wait. I
expect the 4 agents connected to server A to failover to server B and to
see that in the servers list, but nothing changes. Checking the agent
logs I find the following errors:

In this case mmc-int is server A. I can understand the second series of
errors where it tries to fail back to mmc-int and fails because mmc-int
is in maintenance mode. I don't understand the initial failure though.
First why is it trying to fail over to localhost instead of server B and
second why the connection refused error? There is no rhq server on this
agent box to refuse a connection.
I have looked through all the agent and server configuration properties
and I just don't see how the localhost address is getting set in this
case. Any help would be appreciated. Thanks.

Reusing the script plugin
by Al Amyot
I created a customized version of the Script plugin which includes three
metrics (each of which passes a different command line option to the
script). I want to add multiple resources using this plugin (executing
the same script) but each with different environment variables to modify
the behaviour. However I get the following error:
A Script Server with the specified connection properties was already in
inventory.
Can can I create a reusable script plugin like this but apply it to
different resources? It seems that I would have to clone the plugin jar
file multiple jars to work around this error (or at the very least
change the executable each time)
See attached rhq-plugin.xml
