Vikas Dokhe — Thu, 24 Feb 2005 23:02:03 GMT

Hi Vikas

Neither of the measurements you are looking at are a good indication of swap.

In glance use 'w' option to view swap information.
On the command line run:
# swapinfo -tam

Cheers
Con

Vikas,

The way you give out the swap information of top and glance is not correct.
Use command :#swapinfo -ta and glance, after just press w to show swap information.
But note that, only compare the REAL swap (2 types of swap: swap and psuedo-swap)by adding first 2 rows because psuedo swap change time after time.

Cheers,
HMT

Hi,

Use swapinfo command to check your swap.
#swapinfo

man swapinfo for details.

Regards,
Paul
