Hi,
On one of my Linux systems monit erroneously reports the system CPU
usage as “82.6%us, 0.0%sy, 17.3%wa”, while the system is almost
completely idle.
I traced down the problem to /proc/stat reporting CPU times larger than
LONG_MAX, while the code assumes they’re (signed) long.
In function used_system_cpu_sysdep() in file process/sysdep_LINUX.c in ,
changing all “long” variables to “unsigned long long” and changing
sscanf %ld to %llu fixed the problem.
BTW, the CPU times monit reads are the sum of all CPUs times, so for a
four CPU system the problem occurs after 124 days.
Thanks for great product,
Ron
