sar -y o/p description reqd

[Naveen Shetty]

Hi All,

I have a query as below, kindly if some one can put some light on this..!

I have a K460 Server with Hp-Ux 11.0 & MDP connected. MDP is being used for MODEM dialing.
I have a problem like server hanging intermittently without any FLT codes neither any log.

What could be noticed is there are huge no.of rawch/s when being observered thru sar -y o/p.

Pls find the attachment for details.

Kindly if someone suggest are these values shown thru sar -y o/p safe or not..!

Thanks in advance..!
Naveen Shetty.

-y Report tty device activity:

rawch/s Raw input characters per second;
canch/s Input characters per second processed
by canon();
outch/s Output characters per second;
rcvin/s Receive incoming character interrupts
per second;
xmtin/s Transmit outgoing character interrupts
per second;
mdmin/s Modem interrupt rate (not supported;
always 0).

They are not warnings just stats

Have a look at man sar for more info
