Monitors state of running docker containers via SNMP.
The package provides two utilities:
health state collector to be run inside the container
container state collector and SNMP agent daemon
Each container is supposed to run the tallyman command as part of its HEALTHCHECK configuration. This tool takes as its argument the command line that does the actual checking, collects its return and sends it over to the stevedore daemon that acts as a collector and simultaneously as a SNMP subagent, delivering the collected information to the snmpd daemon.
Hostproc provides detailed information about processes running on a host over SNMP. The information is grouped in a way similar to the ps(1) output. Additional aggregating features allow the administrator to provide summary statistics for processes matching some criteria and to 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.
The program is built as a sub-agent for Net-SNMP snmpd and is Linux-specific.
