SysLog Forwarding for XenServer

When I did that, I forwarded them to a VM running Splunk, and it showed right up.
In fact, I've done so much, I forgot to re-enable that. Just did, and it showed right up again.
Just set the option in XC, and that was it. Immediately showed up in my Splunk install.

So now I need a VM with splunk as well?
Or can I use my CentOS Rsyslog Vm as well?

For my XenServer (still 6.5), I actually started up the XenCenter app. Right click on the server -> properties -> click log destination on left -> click remote on right and enter the rsyslog server ip.
Which I've done that, but where on the syslog VM would I actually see the logs being created? What should I modify in the /var/lib/syslog.conf file on XenServer?
By default, everything goes in /var/log/messages. If you want to find things for just one host name
sudo cat /var/log/messages | grep 'hostname'I'm now understanding why @scottalanmiller likes binary logs instead of ascii. That messages file grows quickly.
-
@travisdh1 That does show a lot of information, which is scrolling very quickly!
I guess it works
-
So if that works, then I need to setup a easy way to view these messages..
Is splunk the go to solution for this?

I used Splunk because it is free and easy.
(For me.)I tried setting up a few other things, and gave up. (Like loggly.) I want to get back to other logging stuff some day, but it works for me.

Splunk is free only for very small sizes. Once your logs grow or you have more than a few servers you normally overrun the free part.
-
So what would be a good aggregation tool to be able to view the logs?
If Splunk stops at a tiny level..... I won't bother with it.

500MB per day.

yeah that's worthless......

You'll want to avoid logg.ly before someone recommends it, then. That is 200MB per day.

So elk/logstash then?
Wasn't there a post around here by scott on how to set this up?

Has anyone setup syslog with Elk (with Elasticsearch 2.3 or greater) and Kibana
-
@DustinB3403 Maybe one of these?

I was actually just looking at that and Kibana...
I'm trying to determine if I can run it locally or if I need a DO account to do it...

I'm pretty sure my walkthrough covers that.
-
@scottalanmiller This one, correct?
-
-
Let me know how it goes. I'd love to install another free server around here.
TAKE THAT MICROSOFT!
