How do you guys handle clients who abuse I/O, other resources
Obviously, if you have clients that run dd tests 24/7, it's going to have some sort of impact on other clients. I currently have a client that absolutely tears through bandwidth (no p2p traffic, so I'm thinking he's running a caching server or something) and he's hitting our drives pretty hard.
So my question is, how do you guys handle resource abuse? Do you warn your clients, suspend them, or what?

Tell him to knock it off!
Don't you have bandwidth allocation limits? If use it all up ask them to pay for more at least?
If you are selling unlimited refer to your own TOS where you describe what exactly is unlimited because it doesn't exist.
This isn't abuse. They are using their allocated resources.
IO abuse is a different issue - I would raise a ticket and discuss with them before taking further action. It sounds like you haven't.
@Spencer Hah, sounds like a plan to me!
If I was a provider, personally I'd....

As @concerto49 said, contact him/her. Let them know they're abusing disk I/O.
Have a 'sit down' and talk about options available:
Odds are you could have them upgrade if you work with them.
@telephone exactly what I was thinking. Im not worried about the bandwidth, be cause its what we allotted him, he's entitled to it. I'm more worried about the possibility of, like you said, an unoptimized script.
It's really no big deal, just wondering what the norm was for handling resource abuse. Thanks, appreciate the help
A little bit of ionice and open a ticket to start a friendly dialogue. Generally goes a long way. People seem to like it when you offer to work with them rather than just telling them to stop.
We are conservative with out plans / promises so when the user actually tries to use what he paid for - this is not an abuse and doesn't affect others. I don't think we had to talk with a customer about "resource abuse" in the last 5-6 months or even more.
Wait for their response within 3 days before suspending their accounts.
Seems like most of the people who abuse our I/O are REALLY abusive, so it's typically a ticket with "Stop immediately, thanks" followed by a shutdown if we don't get a prompt reply. If they ignore us, reboot, and continue on, it gets ugly :P
we have a client hosting a video streaming site that uses 700GB HD and over 10-20 TB of bandwidth a month, We spoke with him and now he has a dedicated server and he is paying more as it coursed our server slow port speed, I/O and Sometimes the processor was up to 70%, So that fixed our issue at least, If he was to disagree and say no we would of suspended him, as you cant put 1 client above the rest. Least that is my opinion
A VPS with 700GB HDD and 10-20T of bandwidth is one monster VPS already and should be paying good money, unless you are in the "unlimited" business.
It was a custom VPS and he was paying for it, But in the end we decided dedicated would more suit his needs
and yes we have Unmetered on all our vps we buy high volumes of bandwidth to make it cheaper for clients.
Depending on how severe the issue is ...
Options 2-3 can be looped, till you find a solution with the client :P

Warning > suspension.
Nobody was terminated for abuse, except breaking ToS such as SPAM, fake luxury goods shops and the like.
We have ppl running dektops with firefox and flash in 128-192 MB some tried even in 50 cents, they still run them... But that is not encouraged, we may throttle them when they keep the cores to 100%.
I see you offer generous bw allotments. Unless the user doesnt go above them, you really shouldn't spy.
Some issues, like CPU usage, are handled by an automated system as described in the AUP/TOS the user agrees-to when they sign up.
Other issues, like disk i/o, are handled on a case-by-case basis. Always begins with stopping the container and notifying the user.
We monitor io and auto limit it if a vm is abusing. If they continue to abuse and are risking other customers, they are automatically powered off and we get an alert. Typically this means we'll take a closer look at what they are doing, and a nice email about our fair usage policy & abusing resources leading to termination without further notice. If it continues they are terminated.
Can u throttle him ??? For a while.....he ll come back asking what happened ! Behave like you do not know. He ll soon go away.
And it ends up backfiring as being poor quality of service and such on some thread somewhere...
Throttle AND email will do the best of both worlds.
We wont be having ppl here posting 400 Mhz vCPUs like that is the norm in the provider or that it may mean that CPU is unused and speedstep kicked in...
This is why I have only dedicated servers now for production, I make mistakes sometimes that could lead to high resource usage and leave in anger after that for about 8 hours. I don't want to come back and see that it's offline, wouldn't make me very happy :P.
@GIANT_CRAB
Waiting 3 days is all well and good, but what if they are doing it 24/7 and it is effecting your other customers. You can't expect your other customers to suffer performance loss for 3 days while you wait for the customer to reply.
I agree its insane but @boltersdriveer insists on that.
This depends on the situation. The customer might get something as simple as an alert to fix it soon.
Or in more serious cases their VM is disabled and they are alerted.
