Hello:
I have a number of high-CPU processes that run on 24-core boxes configured e.g.:
check process emr-enc01-01 with pidfile /var/run/tada_liveenc_emr-enc01-01.pid
start program = "/usr/local/tada/launch.sh -c emr-enc01-01"
stop program = "/bin/bash -c 'kill -s SIGTERM `/bin/cat
/var/run/tada_liveenc_emr-enc01-01.pid`'"
if totalmem > 80% then alert
if totalmem > 90% then restart
if totalcpu < 10% for 10 cycles then alert
These processes create pidfiles which match correctly in top as:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
1710 root 20 0 3064m 1.2g 7808 S 578 15.8 47:31.53 tada_liveenc
1866 root 20 0 2954m 1.3g 7804 S 545 16.7 45:18.52 tada_liveenc
However, monit sees these as a completely different total CPU usage:
Process 'emr-enc01-01'

Any thoughts on why this might be happening? Hosts are ubuntu natty. The
master processes themselves spawn about 150 threads (not forks).
FYI:
662 root@enc01[tada]: $ uname -m
x86_64
663 root@enc01[tada]: $ file `which monit`
/usr/local/bin/monit: ELF 64-bit LSB executable, x86-64, version 1 (SYSV),
