Using Cloud Monitoring to Monitor IRIS-Based Applications Deployed in GKE
We’ve shown one of the almost endless approaches to monitoring IRIS applications deployed in GKE. This time we’ve focused on metrics stored in Cloud Monitoring and displayed in Grafana.

"No way to prevent this" say users of only language where this regularly happens
Some of the HN discussion about whether "new projects in C should be allowed" is moot: Fluent Bit was imported into git in 2015 [0] (a few months before Rust's first public release), and may be considerably older than that for all I know.
I suppose incidents like this actually do give a reason to "rewrite it in Rust", when "it" is "widely deployed infrastructure written in C". OTOH, I'm sure there were plenty of non-memory-safety bugs introduced and later fixed over the years, and rewriting in Rust will recapitulate that subset of bugs.
