Re: [Xen-users] Domain level Network and VBD numbers in a loggable format

["Ashish Gupta" <ashishgup@xxxxxxxxx>]

Thanks so much !
I assume from this that there is really no way to get sub-second data
for these metrics unless I add manual tracing events using xentrace to
the xen code ?

cheers,
Ashish

Yes that u can do,

 /usr/sbin/xentop --help
Usage: /usr/sbin/xentop [OPTION]
Displays ongoing information about xen vm resources

-h, --help           display this help and exit
-V, --version        output version information and exit
-d, --delay=SECONDS  seconds between updates (default 3)
-n, --networks       output vif network data
-x, --vbds           output vbd block device data
-r, --repeat-header  repeat table header before each domain
-v, --vcpus          output vcpu data
-b, --batch          output in batch mode, no user input accepted
-i, --iterations     number of iterations before exiting

U shoud use option -b ( Batch ) and -i to get the No of times u want to get the output and then pass stanadard output to a file for later analysis.

Example
#xentop -b -i 10 1>log &

log file contains the output of 10 iterations.

Then use appropriate options to filter the output for either network or others.

Thanks,
Trilok

Hi,

xentop displays network and VBD numbers at the domain level. Can I somehow log them  for offline analysis ?
Are they available in procfs or sysfs ?

thanks!
Ashish
