I wasn't actually doing looking at debug info about struct queue, just looking
up the symbol qt.
On Solaris 9, nm -D /usr/sbin/cron can see that, on Solaris 10 it can't.
It's declared static (in OpenSolaris; it wasn't in the pseudo-release of
Solaris 8 FCS source,
so I can't be sure that it wasn't different before, although I don't think so).
206 static struct queue
207 {
208 int njob; /* limit */
209 int nice; /* nice for execution */
210 int nwait; /* wait time to next execution attempt */
211 int nrun; /* number running */
212 }
213 qd = {100, 2, 60}, /* default values for queue
defs */
214 qt[NQUEUE];
Script follows (only works <= Solaris 9):
#! /bin/ksh
if [ -x /usr/bin/zonename ]; then
ZONEARGS="-z $(zonename)"
else
ZONEARGS=""
fi
# not an ideal solution to getting just the parent, but
# better than taking it for granted that we never see one
# between fork and exec
CRON_PID="$(pgrep -u 0 ${ZONEARGS} -xf /usr/sbin/cron)"
while (( $(print "${CRON_PID}"|wc -w) > 1 ))
do
sleep 1
CRON_PID="$(pgrep -u 0 ${ZONEARGS} -xf /usr/sbin/cron)"
done
if [ -z "${CRON_PID}" ]; then
print -u 2 "cron not running"
exit 1
fi
mdb -p "${CRON_PID}" <<EOF | \
awk 'BEGIN {printf "%10s %10s %10s %10s\n","NJOB","NICE","NWAIT","NRUN"}
NF>=4 {printf "%10d %10d %10d %10d\n",$(NF-3),$(NF-2),$(NF-1),$NF}'
qt,0t26/DDDD
