Service console memory almost full

[Dynamax]

Hi

I have recently increased the service console memory to 800MB. The hosts were working fine before and werent maxing out the original amount of memory. But now its using around 770MB on all servers. When i run 'top' it lists 320 processes the majority of them are webaccess. Is this normal?

thanks

Well for one the Service Console isn't really for you. It's to manage problems on the server. So these performance stats you shouldn't ever 'see'. Did you install any 3rd party managment agents on the ESX server? If not, then unless it's causing performance issues or swap for the SC memory, I wouldn't worry about it.

Also when you increased your service console memory did you increase the size of your swap partion to 2x SC emmory or 1600 MB?

By default, when you run top, you are seeing the active threads. That's why you see so many of the same "process" in your view. You can turn that off by using 'H' to turn off threads. That should bring the process list down a bit, and help you get at what's eating all the memory. As the others pointed out, if you're not swapping, then it shouldn't be an issue.

thanks for your responses.

I havent increased the size of the swapfile but have just seen a post on this so will take a look through that. Good thats its nothing to worry about.

quick quetion though. Obviously fdisk -l will give me the partitions but how do I know what partition is what and if I have space to create another swap file.

thanks

'vdf -h' will tell you which filesystems are mounted on what, as well as /etc/fstab. In your fdisk -l output, type 83 is linux filesystem, 82 is linux swap, fb is vmfs, fc is vmkcore.

thanks

this is the output from vdf -h

Filesystem Size Used Avail Use% Mounted on

/dev/sdv2 9.7G 1.8G 7.4G 20% /

/dev/sdv1 99M 31M 64M 33% /boot

/dev/sdv5 4.9G 252M 4.4G 6% /var/log

/vmfs/devices 136G 0 136G 0% /vmfs/devices

this is the output from fdisk -l | grep /dev/sdv

/dev/sdv7 2007 17769 126616212+ fb Unknown

Please excuse if im being stupid but I assume /dev/sdv3 is the swap partition. How can I call a) the current size and b) if I have space to create a new one

thanks

again

You can use 'swapon -s' or 'cat /proc/swaps' to see your swap information.

From your output, you are using blocks ' 1357 17769 131837422' for your extended partition, of which you are using up to block 17769. This means you have 0 space left on your drive for additional filesystems. You will have to live with a swap that is not 2x your memory. Not a good thing, but it won't really hurt you that much.
