(And if you weren't aware of that: surprise!) As a cloud platform provider, we have a varied tech stack ranging from the many services that power the cloud, from hardware to virtualization software, and even container orchestration tooling. But with many moving pieces comes a vital need: that of observability. Observability is often defined as consisting of three “pillars”: logging, metrics, and tracing. In this post, however, I will focus on metrics, namely how we at DigitalOcean have leveraged Prometheus and Alertmanager for whitebox monitoring both our services and our container clusters. Whether you are a software engineer writing services or an operations engineer maintaining a container orchestration solution, these monitoring and alerting examples should prove useful.","spans":[]},{"type":"heading2","text":"More to Monitoring Than “Knowing When Things Break”","spans":[]},{"type":"paragraph","text":"Before delving into the what and how of monitoring, however, I’ll first focus on the why: specifically, why you—an engineer—should monitor your applications or infrastructure stack. The immediate answer might be “to know when things break”, and naturally, alerting upon downtime or other metrics issues is a vital reason to set up monitoring. In fact, most applications at DigitalOcean have either a whitebox monitoring or blackbox monitoring setup and some basic downtime alerts (sometimes, we have both). But beyond just alerting, proper monitoring allows one to identify long-term trends, analyze performance issues, and set up visualizations. For example, every containerized application deployed on our Kubernetes clusters at DigitalOcean has an automatic dashboard generated with basic stats such as memory and CPU usage as well as traffic. Our clusters themselves also have dashboards. These are essential in visualizing general trends and for debugging during on call rotations:","spans":[]},{"type":"paragraph","text":"Fig. 1: doccserver application dashboard","spans":[{"start":0,"end":40,"type":"em"}]},{"type":"image","url":"https://images.prismic.io/www-static/937739709938d3c2b30dc359fe7104e4bbd463e2_screen-shot-2017-11-02-at-4.18.22-pm.png?auto=compress,format","alt":"doccserver application dashboard","copyright":null,"dimensions":{"width":1600,"height":715}},{"type":"paragraph","text":"I also mentioned that we currently use Prometheus and Alertmanager for both monitoring and alerting: our hows of monitoring. The journey towards using this tooling is also quite interesting and one that I’ve had the opportunity to bear witness to. DigitalOcean originally leveraged Chef and a hodgepodge of scripts or CI/CD tools for provisioning, updates, and deployments. Nagios was commonly utilized (and still is) to perform blackbox monitoring on hosts. This, however, was not enough. While blackbox monitoring is one piece of the puzzle, it doesn’t provide sufficient introspection into applications or truly help with debugging a variety of issues. As a result, engineers went through a long process of trying out several other solutions, which were always lacking in some element. Some were difficult to set up and operationally maintain while others didn’t provide useful visualizations or UX. Furthermore, actually leveraging the data for analysis proved difficult...but along came Prometheus and Alertmanager.","spans":[]},{"type":"paragraph","text":"Four base metrics types are at the core of Prometheus— counters, gauges, summaries, and histograms—which can be combined alongside a powerful query language with various functions for analysis and debugging. Prometheus proved to be extremely easy to install, either via a simple Go binary or Docker container. Furthermore, the fact that the time-series data was multidimensional proved immensely helpful, as our adoption of Prometheus coincided with our move towards containerization; having the ability to label data made analysis and aggregation all the more simple when using tools such as Kubernetes. As a result, Prometheus swiftly became our go-to tool for whitebox monitoring alongside Alertmanager for alerting.","spans":[]},{"type":"heading2","text":"Metrics: Leveraging The Four Golden Signals","spans":[]},{"type":"paragraph","text":"We’ve established the why and how of monitoring; let us now look into the what.

Latency refers to the duration of requests; one important thing to note is that it is vital to consider the distribution of request duration, especially the longtail or 99th percentile. After all, what affects only a few of your users can often be an indication of impending saturation—another golden signal. Saturation itself is defined as the “fullness” of a system; it indicates how long something is waiting to be serviced.

Traffic refers to the amount of demand placed on your system. In a request-based system, this is often measured in HTTP requests per second.
