Does the netstat counter wrap around? And over what period are they collected?

Question

If I run netstat -s on my solaris 10 box, I got a lot of network statistics.

Are these counters since the time of system boot, or some other arbitrary period?

And some of the numbers are quite large. Does it wrap-around at some point?

Answer 1

1) System boot

2) no it depends on what the variable type is ( like long integer etc). You dont have a direct way to make it in readable format unless you pipe the output to do some math. A quick example ( pls ignore the first line. Did not have the patience to get rid of it)

[root@host]# netstat -i

Kernel Interface table

Iface MTU RX-OK RX-ERR RX-DRP RX-OVR TX-OK TX-ERR TX-DRP TX-OVR Flg

ens3 1500 1457 0 0 0 1050 0 0 0 BMRU lo 65536 6 0 0 0 6 0 0 0 LRU

[root@host]# netstat -i | awk '{print $1, $2/1024}'

Kernel 0

Iface 0

ens3 1.46484

lo 64

I hope this helps.
