resource.getrusage is a system resource usage statistics interface provided by the resource module in the Python standard library; on Unix systems it can return data such as CPU time and peak memory for a process and its child processes, reporting the historical maximum of the resident set size through the ru_maxrss field, in units of KB (Linux) or bytes (macOS).

UnverifiedThe ru_maxrss obtained via resource.getrusage is a reliable metric for measuring a process's peak physical memory on Linux, and is more suitable than ps's instantaneous value for evaluating batch tasks.75% similarUnverifiedresource.getrusage(RUSAGE_SELF).ru_maxrss returns the maximum resident set size of the process since startup, used to measure the real memory ceiling.68% similarUnverifiedResource Attributes in OpenTelemetry describe the entity itself that produces the telemetry data (such as service name, host, deployment environment, etc.) and are attached to all traces, metrics and logs exported by that process, as distinct from span attributes that describe a single operation.62% similarUnverifiedSearch and observability systems such as Quickwit and GreptimeDB use object storage as their core storage medium59% similarUnverifiedThe author frees memory between projects with gc.collect() and measures peak RSS rather than average using resource.getrusage(RUSAGE_SELF).ru_maxrss.58% similar
