In an always-on world, companies look to systems and processes to keep their services up and running at all times. The most important part of maintaining this uptime is having an Incident Management process in place to restore your services in the event of an interruption or unplanned downtime. Incident Management processes are typically used by SRE, DevOps, NOC and other IT teams to respond to incidents that affect services and work on restoring their uptime.

Monitoring began by using software agents to capture data from infrastructure, operating systems, and applications. These agents would collect metrics and events from these systems to understand the health of the underlying system and the applications. This is what infrastructure monitoring is today.

Running software uses computer memory for data structures and executable operations. How this memory is accessed and managed depends on the operating system and the programming language. Many modern programming languages manage memory for you, and Ruby is no different. Ruby manages memory usage using a garbage collector (also called gc). In this post, we’ll examine what you, a Ruby developer, need to know about Ruby’s gc. Use the links below to skip ahead in the tutorial.
