collectors ProcessResourcesCollector

ProcessResourcesCollector

A Diamond collector that collects memory usage of each process defined in it's config file by matching them with their executable filepath or the process name. This collector can also be used to collect memory usage for the Diamond process.

Example config file ProcessResourcesCollector.conf

enabled=True
unit=B
cpu_interval=0.1
[process]
[[postgres]]
exe=^\/usr\/lib\/postgresql\/+d.+d\/bin\/postgres$
name=^postgres,^pg

[[diamond]]
selfmon=True

exe and name are both lists of comma-separated regexps.

count_workers defined under [process] will determine whether to count how many workers are there of processes match this [process], for example: cgi workers.

cpu_interval is the interval in seconds used to calculate cpu usage percentage. From psutil's docs:

'''get_cpu_percent(interval=0.1)''' Return a float representing the process CPU utilization as a percentage.

• When interval is > 0.0 compares process times to system CPU times elapsed before and after the interval (blocking).
• When interval is 0.0 compares process times to system CPU times elapsed since last call, returning immediately. In this case is recommended for accuracy that this function be called with at least 0.1 seconds between calls.
