Case Study: Inspeqtor achieves automated process restarts and real-time memory visibility with Datadog

Inspeqtor Process Monitoring with Datadog

Inspeqtor helped an eCommerce company facing a recurring production problem: background worker processes on a Ruby on Rails site steadily leaked memory (from ~300MB to multiple GB), eventually causing out-of-memory crashes. Although Datadog monitored and alerted on the memory growth, the team lacked an automated way to restart the misbehaving workers.

The team installed Inspeqtor on each machine and added simple rules (e.g., restart if memory:rss > 1g) so Inspeqtor scans processes every 15 seconds, finds services via the host init system, and takes immediate action when rules are violated. Inspeqtor Pro can also forward metrics to Datadog via StatsD for visualization, giving automated remediation plus historical visibility — eliminating manual restarts and stabilizing the service.
