Quick answer: Watch for learning about problems from reviews, being surprised by crash spikes, slow detection, and no per-version visibility. Better monitoring catches problems in minutes via alerts, not days later from reviews.
Monitoring is how you catch problems fast, so inadequate monitoring means problems run unseen until they've done damage. Here are the signs your game needs better monitoring.
Learning About Problems From Reviews
The core sign is learning about problems from reviews and complaints rather than from monitoring, you find out about a crash spike or bad update from a pile of one-star reviews, days after it started. If reviews are your problem-detection system, your monitoring is inadequate, you're learning too late to limit the damage.
Bugnet alerts on crash spikes, so you learn about problems in minutes. Learning about problems from reviews is the core sign you need better monitoring, since it means you're catching problems days late (after the damage), monitoring with alerts catches them in minutes (when you can still respond and limit the damage), which is the difference better monitoring makes.
Being Surprised by Crash Spikes and Bad Updates
A sign is being surprised by problems, a crash spike or bad update you had no idea about until it had spread. If you're regularly caught off guard by problems that monitoring should have flagged early, your monitoring isn't catching them fast (or at all), a sign you need alerts that surface problems in minutes.
Bugnet alerts on crash spikes and new issues, so problems reach you fast. Being surprised by crash spikes and bad updates is a sign you need better monitoring, alerts on spikes and new crash signatures surface problems in minutes (so you're not surprised), turning problems you'd otherwise discover late into ones you catch as they start.
Slow Detection and No Per-Version Visibility
Signs include slow problem detection (it takes you a long time to notice issues) and no per-version visibility (you can't tell if a release regressed). Both indicate monitoring gaps: without alerts you detect slowly, and without per-version tracking you can't catch the regressions that monitoring should surface fast.
Bugnet alerts on spikes and tracks per version, enabling fast, per-version detection. Slow detection and no per-version visibility are signs you need better monitoring, alerts (for fast detection) and per-version tracking (to catch regressions and compare builds) are what good monitoring provides, so their absence leaves you detecting slowly and blind to regressions, which better monitoring fixes.
