VPS Load Question

[Joel]

Hi All,

Well we have just started really using our VPS, we moved our main sporting site over too it. Seems to handle it fairly well, except i was uploadng a few photos via the gallery today and spiked the CPU for about 2 seconds or so up to 90%, it then dropped back down.

What is a good load average ?

I had: 0.09, 0.07, 0.01
Now at: 0.0, 0.03, 0.0

CPU Working at 24% in the virtuzzo resources panel.

What is an acceptable load on your VPS ?

Regards,

Joel

Also to note, there is nothing in the QOS logs.

You're lucky Joel. What server are you on? I'm on Apollo, and can't even GET to the virtuzzo panel at this point. NO FTP, WHM took 20 minutes to load.

I just moved onto this server in the past three weeks and am still in the process of moving my clients--mostly small restaurants and private sites, or small businesses, 30 in all, and I can't seem to get the damned server to stay sober long enough to finish an AA meeting.

My status was 24% or so also, but I'm seeing big back office failures every day now.

For the record, Joel, help text says...

Load Average for the CPU usage is the average number of active processes for the past 1, 5, and 15 minutes, respectively. Value 0.00 means that the CPU is idle, 1.00 that the CPU is fully used. Value 2.00 denotes that the CPU load exceeds the nominal value by two times.

My times for the past 15 minutes are:
4.42, 4.11, 2.57

Which is interesting, considering that there's no one using the system at this point. Only the root signed on trying to find out what is happening.

It's doubtless a mis-configuration.

This is a common misconception.

Here's an explanation

God, thanks for the great explanation, Ron.

So, when I cannot FTP to the host, it's just

A COMMON MISCONCEPTION.

When I cannot restart the FTP server, it's just

A COMMON MISCONCEPTION

When my WHM won't load, it's just

A COMMON MISCONCEPTION.

The common misconception here is that overloading servers with VPS clients and giving them rosy-assed sales claims such as:

"Rest assured that hosting with JaguarPC
is a hassle-free experience, your data is safe, your site is working properly, and you're backed by the industry’s best customer support.
Come experience our friendly and highly trained professional staff, extensive and proven security features, and access to a reliable high
performance state-of-the-art network."

Aren't going to get some new users looking at fraud in the inducement to whack JAGUARPC with the cost of switching thirty clients to their servers when they offer some really, very crappy and drilled down slices of service for a fortune.

irishrow, with that sort of a piss and whine attitude i feel sorry for anyone even considering giving you further help. Ron has clearly explained what the loads mean, and he is NOT saying this is what is causing YOUR problems. Rather I was asking about load issue.

Go make your own topic to piss and moan in.

there are alot of cry babies here, get use to it


I really fell sorry for his customers, which he alludes to in his post, I am sure he is probally a cheap ass who about the cheapest VPS, installed Cpanel (which that package is not designed for) and expects everything to be all well and good..


To your orginal Question, that are great loads but probally will go up as the server is used more, but I would not worry about it too much, If you see a slow down make sure your site has not gotten too busy for the plan before you start complaining. This is the main draw back of VPS...

[irishrow]

Gentlemen, it seems that all of us are assuming things, and most of us are wrong. I purchased a VPS plan that provides 3X the DASD and 50X the bandwidth (yes, that's as in fifty times) my clients need and historically used, and did so just to get the memory that larger package offered, and then increased the memory by 30% as an add-on, and I pay 3X the base rate for VPS. My CPU usage was at 2% around the time of my problems with "load average" translated into lost server facilities.

This client should be rattling around on an oversized server, with his larger clients yet to be switched over, but this load issue raises its head when root services deteriorate, ftp is lost and for some reason, the resources go into the black zone at 5 am two days in a row.

Crybaby? I don't think so.

Joel asked the question about load. I gave him the manual's answer; Ron said it's a common misconception that running a load factor of 4.50 would really cause you problems, and I begged to differ.

I can go to my own posts now, Joel, but respectfully, you asked what it meant and Bertrand Russell, the REAL ANCIENT, has the best answer: When it comes to load factor,

"Don't let grammer dictate to ontology."

Neptune is no better. All the sites on my VPS have slowed to a crawl the last few days with the Control Panel unusable and 4 x 1/2 hour outages to make things interesting. Then yesterday I couldn't even log into the support page (this has now been fixed apparently)!

As per usual, whenever support looks into it everything is working just fine...and their logs show a rosy garden

Irishrow, Please open a support ticket with the details of the problem you are experiencing so we can assist you.
Jagged, we provide you only with real logs from your server, we do not "make up" any logs You can always login to your server and check the logs yourself too.

Irishrow,

I understand you're frustrated, and apparently don't know how to control your emotions and direct your frustration in a more positive direction than sarcasm.

As to server load, I've just run on a node all last week that had a load of 10 all week long as it was running rsync across a network to migrate users. It wasn't as "snappy" as usual (or as you), but it was running well enough that I didn't raise a stink.

A VPS can be affected by as many things as a dedicated server that are visible to the owner of the partition. However a VPS also has other things going on, lile burstable memory allocations and hard disk contention that you can't see.

For instance, when one of your neighbors has a memory requirement higher than his guarantee, and the system allows him to burst over his allotement, what do you think happens when you and your other neighbors come along and need your full allotment? My theory is that everything "grinds to a halt" for everyone as memory is cleared by writing it down to disk. You got a better theory?

How about when one of your neighbors runs something that uses a ton of disk I/O, something that isn't throttled in the current version of Virtuozzo, as far as I can tell?

Both of these could cause "server load" to go sky high in your VE, but would have nothing whatever to do with the processes you're running, and wouldn't be considered a "misconfiguration", either.

Of course you're running CPanel, and it runs a ton of stuff all the time, frequently swamping the resources of smaller VPSes. WHM is a dog, and it takes a long time to load on a full featured, full blown server, and some of it's tasks take more than a minute of CPU time just to open a window. If you're getting 5-10% of a server's CPU time, that could be 5-20 minutes.

I wish you luck.

[irishrow]

Well, Ron, I apologize for "snapping" it what seemed to be your direction...it really wasn't. I used your phrasing to pose a question in the forum to vent the irony of missed promises with VPS...You offered a very tempered explanation, and I thank you for it.

There's a lot of forum members that denigrate cPanel, but they seem oblivious to the fact that clients actually LIKE the product and demand it for their installations as something familiar, reliable and easy to use. While I resell, my business is web development and I'm simply trying to provide a common server for a customer base with a lot of integrity and basic needs as far as a server goes.

But I need FTP to work and I know when it doesn't...if it's between 7 am and 6 pm, I'll know immediately, and that's been every day this week.

I've been in touch with support on this issue--before and after these posts--and my conclusion is that, for the small number of low bandwidth clients on a VPS provisioned as this one is, the QoS is appalling. As I stated from the outset, I think the configuration needs to be analyzed and tweaked. Seriously tweaked.

I could tell you more about it, Ron, but my Virtuozzo Panel has a misconfiguration error right now and none of the logs are available there...even though the server otherwise appears to be running normally and putty tells me the server load is 0.11.

Go figure. Well, you already have, mightily. Thank you.

[Ron]

When I say "Dog" I mean it as in "runs like a dog", which means it's slow, but my dog can run pretty fast, so I don't know where that expression comes from.

I run WHM/CPanel as a "reseller" as well, but facts are facts. The thing is incredibly resource hungry.

Aha! My dog is always hungry. Maybe that's the analogy.

[jagged]

Jagged, we provide you only with real logs from your server, we do not "make up" any logs You can always login to your server and check the logs yourself too.

LOL no wonder support can't find anything wrong if it's just my VPS logs they are looking at. They won't say why the server as a a whole is running slow or why the connection to the outside world appears to fail several times a month (or several times in the last week, this month). That's why I ask support - because these are issues about which I have no control and limited information. I do give any info I've managed to find but it doesn't matter how I phrase the question, the answer always seems to be....

"is loading fine at our end also we have not experinced any such problem"

"I have checked all the settings seems to be correct"

"I have checked the mail server logs but I was not able to find any particular error"

"I've checked the hardware node as well as your VPS but I don't see any load issues on both"

"I have checked and both services are up and running on your vps, FTP and Mysql."

"I have checked the hardware node's load as well as your VPS load and both are normal."

"Your VPS load is also normal."

"I have checked both hardware node and the VPS. The load on both are too normal."

That last reply really amused me...how can the load on the VPS be too normal? Maybe that's my problem, my VPS just isn't very interesting and the server occasionally nods off

Cheers
Jag

PS The normal service I wasn't getting that wasn't abnormal has now mysteriously resumed normality, for now. No change there then!
