Package: sysstat
Version: 8.0.4-1
Severity: wishlist
A bit nitpicking here (sorry but I was annoyed):
Probably too late and for upstream:
the default value for count is 0 for sar but "endless" for pidstat.
Some consistency would be nice there.
Example:
$pidstat -d 2
will enter endless loop
while
$sar -n ALL 2
will only print once
At least pidstat should interpret a count value of 0 as endless like
sar. This way you can always specify interval and count and don't have
to think about which tool you are using. At the moment specifying a
count value of 0 is not allowed by pidstat:
$ pidstat -d 2 0
Usage: pidstat [ options... ] [ <interval> [ <count> ] ]
Options are:
[ -C <comm> ] [ -d ] [ -I ] [ -r ] [ -t ] [ -u ] [ -V ] [ -w ]
[ -p { <pid> | SELF | ALL } ] [ -T { TASK | CHILD | ALL } ]
Another point:
both tools print an average even if count is 1 and I could not find
a switch to disable average printing
PS: what's wrong with watch (or watch -d)? hmm ok no average printing
