Jmx4Perl provides an alternate way of accessing Java JEE Server management interfaces that are based on JMX (Java Management Extensions). It is an agent-based approach where a small Web application deployed on the application server provides HTTP/JSON-based access to JMX MBeans registered within the application server. It is set up from a handful of Perl modules, which can be integrated seamlessly in your own programs. It also includes a Nagios plugin, check_jmx4perl, a jmx4perl command line tool for remote JMX queries and operations, and a readline-based JMX shell j4psh, with context sensitive command completion and syntax highlighting.
snmpd-pyagentx provides Python3 bindings for AgentX extension of the snmpd part of the Net-SNMP project. It allows you to tie into snmpd, returning your own values for OIDs or whole OID trees right from the Python code. It consists of a thin C interface for snmp_agent_api(3), provided by net-snmp project libraries, and pure Python logic for handling forwarded requests. The C code is loosely based on the python-agentx project codebase by Bozhin Zafirov.
LaunchControl is a fully-featured launchd(8) frontend allowing you to manage and debug system and user services on your Mac. It provides everything you need to load, unload, start, create, edit, remove, or troubleshoot launch services. It supports all documented features of launchd, reports potential problems before a job is even started, and makes sure you always create valid configurations. It supports user LaunchAgents and Global and System LaunchAgents/Daemons. It shows all services and their status at a glance, and misconfigured services are highlighted. You can enable or disable services, and find them with a job filter. Not just a plist editor, it provides a dedicated interface for every configuration key with an adaptive interface that displays only information relevant for the selected job.
