Issues getting agents working on FreeBSD 8 (amd64)

[treyhyde]

No wrappers are provided for FreeBSD amd64 so I thought I'd follow the advice given on many google results and use the nowrapper.sh script ....

hyperic-hq-agent-4.3.0/bundles/agent-4.3.0-1443# ./bin/hq-agent-nowrapper.sh start

So it's probably having trouble finding libsigar or similar. I tried installing the sigar FreeBSD port but that didn't help. I haven't worked much with JNI so not sure what the best way of going about debugging these sorts of library issues are.

On Hyperic 4.2 it just exited without providing any useful info at all

Anyone have any suggestions?

Hi,

what files did you install ?
Did you download and install the library from the following URL ?
http://hudson.hyperic.com/view/sigar/job/sigar-1.6-amd64-freebsd-8.0/lastBuild/

Cheers,
Mirko

[excowboy]

Hi,

I forgot to mention that you can invoke SIGAR standalone, e.g.

java -jar hyperic-hq-agent-4.2.0/bundles/agent-4.2.0-1260/pdk/lib/sigar.jar ls /var/log/syslog

On HQ 4.2 you can also run the following command, to run a couple of tests:

java -jar hyperic-hq-agent-4.2.0/bundles/agent-4.2.0-1260/pdk/lib/sigar.jar test

I installed sigar 1.6.3 out of the FreeBSD ports system.

So yes, confirmed, it's not finding sigar. I'll give the non-FreeBSD port package that you listed a try instead. FreeBSD ports does not generate the .so with that name.

[treyhyde]

I installed libsigar from that link by putting the so in pdk/lib

$ ls -ltr pdk/lib/*freebsd*
-rw-r--r-- 1 arnulf wheel 211780 Aug 24 2009 pdk/lib/libsigar-amd64-freebsd-8.so

-rw-r--r-- 1 arnulf wheel 179379 May 17 16:32 pdk/lib/libsigar-x86-freebsd-6.so

I still get

sigar.jar gave me a bit more info

and now it works ...

Thanks

[treyhyde]

Actually, not works but got a bit further around, it seems the agent never gets started after the setup.


What IP should HQ use to contact the agent [default=192.168.2.112]:
What port should HQ use to contact the agent [default=2144]:
- Received temporary auth token from agent
- Registering agent with HQ
- Unable to register agent: Failed to connect to agent: Unable to connect to 192.168.2.112:2144: Connection refused

[treyhyde]

see previous post... still not working, marking as unanswered

[mcmesser]

We generally only see this error when firewall rules are not allowing the server to communicate to the agent on the port specified. Can you test that?

[treyhyde]

There are no software firewalls on this machine.

I just came to the bottom of it... this agent is not detecting its IP address correctly.

HQ thinks it is .112 but in reality this host is .113. I'm really perplexed on how it came up with .112. There are no entries in /etc/hosts and DNS is correct. Where is hyperic pulling the local IP from?


What IP should HQ use to contact the agent [default=192.168.2.112]: 192.168.2.113

The agent is now communicating with the server.

[mcmesser]

The agent asks the OS for the active interfaces and picks the first one. So 192.168.2.112 doesn't appear anywhere in the 'ifconfig -a' output?

[treyhyde]

Nope, I'm a bit perplexed.

[mcmesser]

Peculiar. And you're absolutely certain there's no rogue entry in /etc/hosts?

[treyhyde]

Actually, there are so rogue entries in /etc/hosts. Not sure what happened there. Thanks
