Anyone Use SeeFusion for performance monitoring?

[Andrew Thielen]

We are considering SeeFusion to get a handle on what's going on with our
newly built/in production CF7 servers to find out why CF7/Jrun locks up
every four days or so. Anyone have any reviews or experience they care
to share?

Or, even better, perhaps someone might have an idea why applications
which worked without fail on CF 6.1 Win2K 1g RAM dual processor and
external MSSQL 7 quad processor for months on end (all error logs were
clean!!!) now fail every 3-4 days
On CF 7.01 Win2003 2g RAM Quad processor with no changes to the code. We
know it's not IIS because we can still load straight up HTML from IIS
while Jrun is unresponsive. Even more perplexing is that we aren't
sending significant traffic to any one server in the pool yet!

We're using CFUSION, and it saved our butt on many occasions.  But it will
probably not help you narrow down why something is failing every couple of
days... It's more for monitoring real time stuff.  But don't take my word
for it, just put it on your server.  I believe a limited time version is
free, and we've never hit the limit, but we did buy the full license pretty
early on.  The problem with CFUSION is when JRUN dies, so does CFUSION.  So
unless you're using the enterprise version and logging to the database, you
won't be able to see what was the last page that cause the error.  

I suggest checking up on your updates.  Is CF7/Jrun up to the latest
updates?  That's the most likely culprit.  We've had strange CF shutdowns
every so often, with no real reason behind it.  Then we've put all the
latest CF patches on it, and the problem magically went away.  

Also make sure you're up to date on windows updates.  Probably not what's
causing the problem, but you never know...

Thanks for the info. As far as I know we're running with all of the
latest updates (I'll double check with the network admins on the Windows
2003 side). We've had a lot of experience with CF and have been
migrating our infrastructure through successive versions since 4 (can
you believe it?) and this is the first time we've encountered such bad
behavior with fully tested prior production code on new CF servers.
Thank the network gods for hardware load balancers. At least that masks
the problem.
