Optimized performance counter monitoring

In a management system, computing devices collect sample performance values that describe utilization or usage of resources or processes. The sample performance values may be in the form of performance data or performance counters. Sample performance values are either sent or not sent to a management server, based on a delta value of a current collected sample performance value and a last current collected sample value. Plots may be constructed based on actual received sample performance values and interpolated, or estimated sample performance values based on a known frequency at which the sample performance values are collected.
