By default metrics are only updated every 10 seconds; this can be
controlled via

Hello,
What is the recommended way to get metrics (such as CPU, Memory and
user defined meters and gauges) at the highest frequency rate (i.e.
with the highest/fastest refresh rate) such as every 500 milliseconds
or less?
Is there any rate limiting by default on querying the REST API for
metrics? I am querying the REST API every second but not seeing any
change in the CPU load for every second, so I was wondering if there
is any maximum frequency at which I can query it.
Thanks,
Piper
