Hostproc is a Net-SNMP sub-agent that interfaces directly with the
Linux /proc filesystem and provides, over SNMP, detailed
information about processes running on the server. The information is
grouped in a way similar to the ps output. Additional
aggregating features allow the administrator to provide summary
statistics for processes matching some criteria and to optionally
exclude such processes from the detailed output. The latter feature
can be used, in particular, to separate statistics for processes
running on the host from those that are run within docker containers.
