Unable to Import Agent System in RHQ-4.5
by Prashant Nagaraja
Hi,
I upgraded my server and agents from RH-4.4 to RHQ-4.5. When I am trying to
import a system / resource through the discovered queue, I get error
Failed to import Resources
in the Administrator GUI. The logs/rhq-server-log4j.log is attached to the
mail.
Please help me to resolve this issue.

Issues in RHQ 4.5.0 identified - please don't upgrade from 4.4 yet
by Heiko W.Rupp
Hello,
we have identified two issues in the RHQ 4.5.0 release
1) on upgrade from a previous version some properties may cause Hibernate errors
2) some resources do not show child resources in their inventory tab (but in the left tree).
As 1) is serious if you don't plan to do a fresh install, we ask you to not update from
any earlier version to RHQ 4.5.0
We are currently working on fixes and will re-spin the release soon.
Heiko on behalf of the team.

Custom JMX plugin data format
by Alex Ont
Hi,
When using a custom JMX plugin (as in the demo), what kind of data should
an MBean return in order to be able to display the operation's result using
a configuration like (rhq-plugin.xml)
<operation name="snapshot"
displayName="snapshot"
description="Process snapshot.">
<results>
<c:list-property name="snapshots">
<c:map-property name="snapshot">
<c:simple-property name="id" description="process id"/>
<c:simple-property name="timeStamp"
description="timestamp"/>
<c:simple-property name="value" > </c:simple-property>
</c:map-property>
</c:list-property>
</results>
</operation>
I've tried various combinations with Open MBean, but couldn't make it work.
Any ideas? Or can someone indicate a working example?
Thank you,
Alex

Webdav users?
by Heiko W.Rupp
Hi,
are there any users of the webdav module out there?
This got removed from the build in December last year.
If there are no objections, I would completely remove that from the sources
for RHQ 4.5

Fwd: Sigar & glibc

Making sure users get notified of this change too...

No, glibc is backwards compatible. Today it works more or less the same way. Sigar links against and older glibc version but it works on Linux distros with newer versions. The linking part is what is going to change.
Here is the ldd output for the Linux x86 native library distributed with RHQ 4.4:
linux-gate.so.1 => (0x00f6d000)
libc.so.6 => /lib/libc.so.6 (0x0034c000)
/lib/ld-linux.so.2 (0x4261e000)
Version information:
./libsigar-x86-linux.so:
libc.so.6 (GLIBC_2.1) => /lib/libc.so.6
libc.so.6 (GLIBC_2.0) => /lib/libc.so.6
And here is the ldd output for the Linux x86 native library to be distributed with RHQ 4.5:
linux-gate.so.1 => (0x00236000)
libc.so.6 => /lib/libc.so.6 (0x003e0000)
/lib/ld-linux.so.2 (0x4261e000)
Version information:
./libsigar-x86-linux.so:
libc.so.6 (GLIBC_2.1.3) => /lib/libc.so.6
libc.so.6 (GLIBC_2.3.4) => /lib/libc.so.6
libc.so.6 (GLIBC_2.3) => /lib/libc.so.6
libc.so.6 (GLIBC_2.1.2) => /lib/libc.so.6
libc.so.6 (GLIBC_2.2) => /lib/libc.so.6
libc.so.6 (GLIBC_2.1) => /lib/libc.so.6
libc.so.6 (GLIBC_2.0) => /lib/libc.so.6
If I interpret this output correctly, the newer binary requires a minimum glibc version of 2.3.4 (even though it was built against glibc 2.5) while the old one links against 2.1. So with this change support would be dropped for all distros that use glibc versions prior to 2.3.4.
Maybe somebody with more experience can shed more light into this library linking ...
Thank you,
Stefan Negrea
