How to know what the "processes" are?

[RaZor Edge]

Hi,

Sometimes, when I do a "Top" command on my VPS, I see the number of processes go up really high. So, it will go from something like "65", go up to something like "121" during 5 seconds.. and slowly get back to normal.

Ex. of a normal top command:

 
19:27:57 up 4 days, 14:20, 1 user, load average: 0.62, 0.84, 0.91

Can you tell me how can I identify what are the processes running when this strange behavior happen? In fact, I want to known if this is caused by a script or a special page on my VPS...

I have try looking at Apache Status and CPU/Memory/MySQL Usage in WHM... but I don't seems to find anything useful there...

One more question...

I was talking about server optimisation on vbulletin.com, and the subject came to "swap memory". Eva2000 (who work for vbulletin and help people with server configuration), said this:

definitely not normal.... IF it was normal server... but VPS servers always use alot of swap for some reason...

i'd probably just request host to move you to a less crowded VPS server

http://www.vbulletin.com/forum/showt...18#post1063618

Is it true that VPS tend to use more swap memory?

Hi RaZor Edge,

About your first post: it would be more useful if you could show the output of "ps -aux", during high and low usage, because that will show all processes and more details about it. Most likely during high usage either the mailserver, webserver, or mysql is running more processes than during low usage, but it's hard to tell without seeing the output of ps -aux.

As for that remark from Eva2000: what you are seeing there is the RAM and swap usage of the entire server, not just of your VPS. Also, due to how linux works, once swap space has been used, the server will just keep those swap pages in use unless there isn't enough additional swap space available. It does that so that in case the swap pages are requested again, the server can access them very fast. So for instance if the server uses 5mb swap on day 1, and 10 days later it uses another 5mb, then it'll seem like 10mb is being used. But that other 5mb won't be used anymore by that time, but until the server gets rebooted it'll just keep those pages in the swap (since there is plenty of swap space available there's not really a need to flush it).

Furthermore, your guaranteed ram will never use swap, it always uses ram. I can assure you that none of our servers are overbooked, we do not oversell any guaranteed ram.

In case you have load issues we'd be glad to investigate that for you, feel free to open a support ticket at any time.

I see! So, if I want to see my VPS memory usage... I must go into Virtuozzo?

Thank you for taking time to explain all this to me. It's really helpful!

Ps -aux, that's what I was looking for!

The results after I restated Apache and SQL are much better than the previous one (where services was running for about 2 or 3 days)!!!

In case you have load issues we'd be glad to investigate that for you, feel free to open a support ticket at any time.

In fact, my VPS "load" are usually not bad... but if you think we can optimize them more (from what I have read, on linux, we are not suppose to restart services often to have good results... so maybe there is something to investigate here), I will open a ticket.

Thank you very much Andre!! Fast reply on troubletickets and your active participation on the forum are two things I really like about Dehe!!!
