Subject Re: tomcat thread incurring CPU load
Date Mon, 11 Nov 2019 20:57:10 GMT
Hello All,

Any thoughts regarding this? Slightly clueless at this point, so any
direction will be appreciated.

We are seeing the poll taking all the CPU time. We are using
OperatingSystemMXBean.getProcessCpuLoad() and
OperatingSystemMXBean.getSystemCpuLoad() to get our metrics (then x100 to
get the pct).

Thanks,
