In Part 1 we’ve described what container monitoring is and why you need it. Because each container typically runs a single process, has its own environment, utilizes virtual networks, or has various methods of managing storage. Traditional monitoring solutions take metrics from each server and the applications they run. These servers and applications running on them are typically very static, with very long uptimes.

Even though containers have been around for ages, it wasn’t until Docker showed up that containers really became widely adopted. Docker has made it easier, faster, and cheaper to deploy containerized applications. However, organizations that adopt container orchestration tools for application deployment face new maintenance challenges.

As the open-source monitoring system Prometheus grew, so did the need to grow its capacity in a way that is multi-tenant and horizontally-scalable, along with the ability to handle infinite amounts of long-term storage. So in 2016, Julius Volz and Tom Wilkie (who is now at Grafana Labs) started Project Frankenstein, which was eventually renamed Cortex.

AWS VPC Flow Logs record details about the traffic passing through your application, including requests that were allowed or denied according to your ACL (access control list) rules. It also has information about the IP addresses, and ports for each request, the number of packets, bytes sent, and timestamps for each request. This information brings deep visibility and the ability to improve your security posture over time.

(This is the first post by our new head of Customer Success, Irving.) Sampling is a must for applications at scale; it’s a technique for reducing the burden on your infrastructure and telemetry systems by only keeping data on a statistical sample of requests rather than 100% of requests. Large systems may produce large volumes of similar requests which can be de-duplicated.
