SysLog Forwarding for XenServer
-
I donwloaded the Graylog OVA this morning to test it out and put it on my XS pool. Just set Xencenter to forward logs to the Graylog server, seems to work well. Xenserver still making local log entries, but i am ok with that.
Xenserver sure does like logging messages. 2 hosts making a couple hundred messages/minute, xenstored and xapi are the top ones by far. -

-
All i did was download and import the ova, then went into Xencenter and forwarded logs on each host to the ip of the graylog server. Here is my sources page
Here is more sources, basically the whole list. I am still quite overwhelmed with the options and config of graylog, but as i get dashboards setup for things and add more log sources i will post them here as well if you would like.
-
I think it is important to note that the graylog ova is preconfigured to 'just work' according to their site, and it seems to do just that. I will try adding some of my windows vm to this and see what happens later today or tomorrow.
-
For some reason I thought / think there are some pretty big limitations to GrayLog.
Maybe I'm wrong.... but I'll take a look at it.

For anyone curious how to stop any local logging just modify
/var/lib/syslog.confComment out everything that hits a local path, leaving the @<ip_addr> as the only option.

Reboot and see if it sticks.
It did not for me.

I cannot get it to import onto my XS.
Did you just import it in with no issues?

That was my issue. On reboot it would wipe out the changes I made.

In a pinch you can do chattr +i on the rsyslog.conf file to make it immutable.

Yeah on the bottom of that article everyone talks about it basically says to change the permission to make it unwritable.
But they call that a QUOTE dirty, dirty tirck UNQUOTE.

I tried on my other XS and it worked fine.
Must have been a memory issue on my test one.

Once I had it imported onto my XS, I had it logging in seconds.
Pretty sweet.
If only I was using open source and virtualization years ago!!!!!!

Yes, no issues. Didn't even use the fixup disc option. Took a few minutes to start up but it worked right away -

When I get some time I'm going to forward all my Windows event logs there.

You've got GrayLog2 working now?
