sys.monitoring â€” Execution event monitoring
Note sys.monitoring is a namespace within the sys module, not an independent module, so there is no need to import sys.monitoring, simply import sys and then use sys.monitoring. This namespace provides access to the functions and constants necessary to activate and control event monitoring. As programs execute, events occur that might be of interest to tools that monitor execution. The sys.monitor

BPFAgent: eBPF for Monitoring at DoorDash - DoorDash
As DoorDash experienced rapid growth over the last few years, we began to see the limits of our traditional methods of monitoring. Metrics, logs, and traces provide vital information about our service ecosystem. But these signals almost entirely rely on application-level instrumentation, which can leave gaps or conflicting semantics across different systems. We decided to seek potential solutions

Logging practices I follow
No matter what kind of software youâ€™re developing, you most definitely leverage logging to some extent, probably every single day. You write a lot of logs, you read tons of them too, it is the most basic observability tool we have. Not all logs are equal / Should you even log it?There are many pitfall that can lead to useless, wasteful and confusing logs. Therefore I follow a specific set of pract
