Mike Perham, CEO of Contributed Systems, recounts his experience with a persistent memory issue at an eCommerce company where he served as Director of Engineering. The problem involved the company's Ruby on Rails app, where background worker processes gradually consumed excessive memory, necessitating manual restarts. Monitoring the system with Datadog provided alerts but not automated solutions, leading Perham to implement Inspeqtor, a Linux-based monitoring software, to automate these restarts. Inspeqtor allows users to define rules for monitoring critical application infrastructure, and in Perham's case, it successfully managed memory usage by automatically restarting processes when they exceeded specified limits. Inspeqtor, which is open source and free, also offers a Pro version with additional features like Statsd integration for enhanced data visualization through Datadog. Perham advocates for the combined use of Inspeqtor and Datadog, highlighting their complementary capabilities in monitoring and problem-solving.
