Seems like all the servers I'm on are slowwww, also this board and the Matrix web site.
The only ones that aren't are mail and IP monitor.
I thought maybe it was my connection (being on the west coast) but I don't know

Everything is moving right along for me at the moment and I am outside of the network.

yeah, it looks good again. Maybe it was a temporary thing with my connection to the east coast.

For the last couple of days I've been having difficulty with anything on nt21. If the sites loads at all, it takes 20-30 seconds. I've sent in a couple of tickets and IIS has been restarted. The sites work great at first (loads instantly), but within minutes are again inaccessible.
Allen
Allen, I just answered your ticket as well. Not sure why your site is slowing down. Are you using any databases or any thing behind the site?

Thanks Brad, no, no dB usage on the site as of yet.
Did you restart IIS? The site is now coming up fine and loading quickly. This morning it would load fine after IIS was restarted, but would quickly deteriorate ( within 5-10 minutes). I will keep checking.
Thank you and all of the techs for the hard work!!! (including Kim, even though she said I don't get no refunds)!!!

Allen if you get that error take a look at http://www.ajlhosting.com/iistracer
If you see something under Running [ms] like over 100,00ms or more then it could be making problems. If your site is slow take a copy of that. That some times helps us find who is making the problem for the reset of the users. Because by the time we get there they may be gone and the server running fine again.

Yeah, it looks like there is a domain todoxxxxx.cl that has a bunch of Auth running. Looks like about 20 that aren't doing much of anything. Perhaps that's the problem witn NT21.
There was a user on NT16 a couple of weeks ago with the same thing. He had a script that was set to timeout after 4 HOURS - trouble is the script was infintely looping, and causing havoc on that server.
Good luck!

Yes, thanks, IIS Tracer is a great tool and your tech support team was nice enough to tell me about it last night.
Is it usual to see 200+ requests being processed?
I've noted, this morning, that when my site is having a problem and I check iistracer it shows 200+ requests and kind of looks like the server is stumbling... When I look at another site on another Matrix server with iistracer I usually see 10-20 requests...

jmbeach... Exactly...
I listed that exact domain in a ticket to tech support. At points they have 150+ requests working... or not working...
Allen
yea that domain is now off i just saw them doing it again.. :(

Brad, could you help us help you by telling us what to look out for when using IISTracer?
Basically, what is a bad/good process - obviously, 'end of request' is good, 'send data' is good I think, but what exactly is 'preproc header'? I'm guessing it along with 'Authentication' is typcally when resources are being used.
Thanks!

jmbeach, Brad... Thank you.
The sites are now working great.

I was just telling you the truth. Credits are issued for downtimes not slow downs.
I was just doing a little poking around with the new (at least to me) toy and noticed that you might want to look into <name removed>.com. If 100,000 ms is bad, these guys are terrible, with about 30 processes up in the 1,000,000 to 13,000,000 range. :(
Not to mention pakistanishop.com
947 893 ms running for 16 mins now and counting

There may be valid reasons for things being high though, for instance downloading a very large file over HTTP on a dialup can easily make some very big numbers there. There is a bit of an art to reading correctly an iistracer log.
Don't look at high numbers and just jump to a conclusion that something is wrong.

I just had a slow time on all of hosted sites. From about 9:30 am PST that lasted about 10 minutes during that time period everything timed out.
Seems to be ok now though.

I agree. I've got a few 10+ meg downloads that could easily take an hour or more on dialup.
Brangwyn, correct me if this is incorrect, but if a transaction is showing Preproc or Authentication, and has a high ms count, isn't that likely a bad process?
Oh, and I think we should all refrain from naming domains entirely - at least give them the benefit of the doubt before presuming guilt. I'm sure we would all hate to be publically named if we had some valid reason for long process times. :)

Preproc or Authentication, and has a high ms count, isn't that likely a bad process?Yes it can, but it also doesnt mean that THAT was the domain that caused the problem just a request that got stuck because of an existing problem.
PREPROC and AUTH are actually before IIS even starts to serve up the page at all, so it can also indicate something else on the machine is amiss.

Very good point. I'm going to go back and edit my previous post. From what I saw though, there was no reason for the pages I saw listed to be taking so long. They were relatively average size .asp pages and did not have extensive image use. I pulled a few of the listed pages up actually and they loaded instantly for me.

It is enlightening tho. nt15 right now has tons of the same process running for a while with asp. Definetly is interesting.
Not all servers seem to have iistracer tho.

If you see times like this 6 114 100 w/ the same process running many times That might be excessive tho right. There's an app on nt15 running about 87 similiar processes with long run times. Why would processes be running multiple times for that long? How can you tell what seems excessive?

yeah, those look suspicious on NT15. I would shoot a TT over to support and give them the IP of the domain that's running all of those. Especially since you can't run a page to see what it is (since it's password protected) I think they should see it.
Plus the fact that they're all running from the same IP client is strange.

Sorry, if I cannot trace my win account sites, could it be because the server hasn't be set?
jmbeach

What server are you trying that isn't working?
Alessandro
08-08-2003, 11:32 AM
Should be NT17 (integraitalia.com)

iistracer should be on all Windows machines - except for NT24 - looks like they haven't added it to that one.
But that server is only a week old or so, so likely you don't have sites on it yet.

Thanks, I got it now ;-)
Curt, if you see them doing that just let us know post them here or send them to us in a ticket so we know who to watch for.. It just helps us keep the servers clean and your site up even more and faster.. :)
