Most of the things that bothered me were fairly minor, but taken together they just didn't give me the impression that there was a lot of effort going into the product. Lots of janky UI (filtering/browsing logs being particularly cumbersome), and a bunch of things that seem promising at first but are very much "lite" versions of more powerful products like Pingdom/Sentry/DataDog. Also I always felt like the monitoring metrics were not as well integrated into the GCP system as they should have been, given that they're under the same roof...we spun up a Prometheus cluster to do it by hand instead.

Also, until recently the admin lived outside of the main GCP admin and logging into it required some kind of redirect-bouncing oauth handshake that was consistently buggy for me. Something to do with browser defaults/3rd party cookies along the chain of redirects that would cause an infinite loop. I managed to work around it on my work computer, but it was broken for at least a year...not awesome for a tool you'll be logging into in emergencies, often from other devices.
