Thanks Mike..<br>I am in the same boat as you are. I have the same hardware, same OS (Solaris 10, Update 9) etc. I also am using the sunfreeware version.<br>One thing that kind of concerns me is the lack of response from other Sun users. There does not seem to be too many that use it for a central log host. Maybe we found out why:))<br>
<br>I too am going down the compiling 3.3 route and am hoping to start next week. <br><br>Agree with the active connections. I mentioned that because we have both. Also, I am going to get rid of the UDP logging since I'm dropping so many packets and move to TCP.<br>
<br>Thanks for that link. Looks pretty good!! Have you been able to get to the link in that document? The one that says Topics in High Performance Messaging? It is supposed to take you to the <a href="http://29west.com">29west.com</a> site but I keep getting redirected to a different site. Don't know if I have malware or if the site is no longer around.<br>
<br>If I get around to compiling 3.3 before you do, I will post back here if you want and let you know how I did it, if you want. I have a friend that is pretty good at it and am hoping it isn't a big deal to do.<br>

I didn't compile it myself, I'm using the 3.1.2 from <a href="http://sunfreeware.com" target="_blank">sunfreeware.com</a>.<br>
I'm actually having a heck of a time figuring out how to compile 3.3<br>
from the alpha2 tarball on Solaris 10. I don't think I'm helping myself<br>
by having all the gcc tools installed from <a href="http://sunfreeware.com" target="_blank">sunfreeware.com</a>, maybe I need<br>
to start over. I'm so much more comfortable on Linux, where stuff just<br>
compiles magically and I don't have to do anything special.<br>
<br>
When you are using loggen, you should write to disk on the receiving end<br>
and compare the number of messages received to messages sent. Clayton<br>
Dukes (on this list) has a good writeup of how to use loggen to generate<br>
some relevant performance numbers here:<br>

<br>
</div>If I had to guess, --active-connections parameter wouldn't apply to UDP<br>
transport. Sounds like a TCP thing.<br>
<br>
Hope this helps!<br>

<br>
Just a heads up Mike. I tried doing the same thing with regards to using<br>
loggen to find the best rate on my V490. My version of loggen did not<br>
have the --active-connections parameter for sure, and I think it didn't<br>
have the --idle connection parameter either. I set the -I to 600 for 10<br>
minutes, and that didn't work either. It ran until I manually killed it<br>
about 25 minutes later.<br>
<br>
Then for the output all I got was :<br>
count=14877 diff=15930 rate = 627.75<br>
<br>
I haven't found what they mean yet. I reckon count would be the number<br>
of packets sent, not sure what diff is, but I know what the msg/sec<br>
is:))<br>
<br>
I am curious to see what you come up with. Oh, did you use the<br>
SunFreeware version or did you compile it yourself?<br>
<br>

Thanks for any testing you can do. I'm not sure if a SPARC<br>

an important testing component or not, I suppose your VMs will<br>
help<br>
determine this since you'll be using x86. If there's any<br>

do to help things along, please let me know.<br>
<br>
Yes, I'm (very) scared of rsyslog as a maintainable solution,<br>
the<br>
configs for syslog-ng are *so* much easier to read and<br>
understand. I'll<br>
try 3.3 and report back how threading helps things out, I'm glad<br>
to hear<br>
that it's been pretty stable for you, that was my major concern<br>
in<br>
testing 3.3 since eventually we'll need this to be in production<br>
with<br>
our basic (from a config complexity standpoint) requirements.<br>
<br>
I'll report back how 3.3 works out for me after I get it<br>
compiled and up<br>
today.<br>

I've been running 3.3 on most systems I administer (2 of my own<br>
servers<br>
+ a few I administer for friends; and all of my virtual<br>
machines). It's<br>
been serving me fine for the past 4 months now.<br>
<br>
However, most of my systems are also linux systems, where<br>
syslog-ng is<br>
much better tested (and I'm not using UDP at all).<br>
<br>
Personally, I'd give it a test run, as current 3.3 is fairly<br>
stable.<br>

I wouldn't consider rsyslog. It's a nightmare to maintain that,<br>
and an<br>
even bigger nightmare to get it to perform well in any but the<br>
most<br>
trivial situations. (Or it might be just me being too used to<br>
good<br>
documentation and readable config files, but I'm fairly sure<br>
it's not<br>
just that :P)<br>
