On July 2. 5th, Luke Marsden from Weaveworks and Bill Maxwell from Rancher Labs led a webinar on A Practical Toolbox to Supercharge Your Kubernetes Cluster. C600' alt='Prometheus 2 Streaming' title='Prometheus 2 Streaming' />In the talk they described how you can use Rancher and Weave Cloud to set up, manage and monitor an app in Kubernetes. In this blog, well discuss how and why Weave developed the best practice RED method for monitoring apps with Prometheus. What is Prometheus Monitoring You may have heard a lot about Prometheus lately, especially when it comes to monitoring applications in Kubernetes. To provide a bit of background before we delve into the RED method, apps running in containers and orchestrated by Kubernetes are highly automated and dynamic, and so, when it comes to monitoring applications in these environments, traditional server based monitoring tools designed for static services are not sufficient. This is where Prometheus comes in. Prometheus 2 Streaming' title='Prometheus 2 Streaming' />Prometheus is an open source project that was originally developed by engineers at Sound. Cloud. It was built and designed specially to monitor microservices that run in containers. Data is scraped from running services at time intervals and saved to a time series database where it can be queried via the Prom. QL language. Because the data is stored as a time series, it allows you to explore those time intervals to diagnose problems when they occurred and to also analyze long term monitoring trends with your infrastructure two awesomely powerful features of Prometheus. At Weaveworks we built on the open source distribution of Prometheus and created a scalable, multi tenant version that is part of our Software as a Service called Weave Cloud. After having run this service for several months now, and by using Weave Cloud to monitor itself, weve learned a few things about monitoring cloud native applications and devised a system that we use in determining what to measure before instrumenting code.

What to Instrument One of the most important decisions to make when setting up Prometheus Monitoring is deciding on the type of metrics you need to collect about your app. The metrics you choose simplifies troubleshooting when a problem occurs and also enables you to stay on top of the stability of your services and infrastructure. To help us think about whats important to instrument, we defined a system that we call the RED method. The RED method follows on the principles outlined in the Four Golden Signals developed by Google Site Reliability Engineers or SREs, which focuses on measuring things that end users care about when using your web services. With the RED method, three key metrics are instrumented that monitor every microservice in your architecture Request Rate the number of requests, per second, your services are serving. Strand Dna Activation'>Strand Dna Activation. Request Errors the number of failed requests per second. Request Duration The amount of time each request takes expressed as a time interval. Rate, Errors and Duration attempt to cover the most obvious web service issues. These metrics also capture an error rate that is expressed as a proportion of request rate. With these three basic metrics, we believe the most common problems that can result in poor customer satisfaction are covered. For even more detailed coverage, you may also include the Saturation metric. Saturation is used in another methodology called the USE or Utilization, Saturation and Errors method and it refers to a resource with extra work that cant be serviced and therefore must be added to the queue for later processing. USE vs. RED Methods. The USE method focuses more on monitoring performance and is meant to be used as a starting point in identifying the root cause of performance issues and other systemic bottlenecks. Ideally, both the USE and the RED Methods can be used together when monitoring your applications. Why you should measure the same metrics for every service. From a monitoring perspective, the benefits of treating each service the same is scalability in your operations teams. What does scalability of an operations team mean We look at this from the point of view of how many services a given team can support. In an ideal world, the number of services the team can support would be independent from its team size, and instead dependent on other factors like what kind of response SLA you want, and whether you need 2. How do you decouple the number of services you can support from the team size By making every service look, feel and taste the same. This reduces the amount of service specific training the team needs, and also reduces the service specific special cases the oncalls need to memorize for those high pressure incident response scenarios or what is referred to as cognitive load. Capacity planning Do it as a function of QPS and latency. Automating tasks and creating alerts An advantage of the RED method is that it helps you to think about how to display information in your dashboards. With just these three metrics, you can standardize on the layout of your dashboards to make it even simpler to read and to create alerts on for when there is a problem. For example, a possible layout might entail a different Weave Cloud notebook for each service with Prom. QL queries for request error, and latency for each of those services. Also it goes without saying, but if you treat all your services the same, repetitive tasks are more easily automated. Prom. QL query. RED Method Metrics Monitored in Weave Cloud. Limitations. It is fair to say this method only works for request driven services it breaks down for batch oriented or streaming services for instance. It is also not all encompassing. There are times you will need to monitor other things the USE Method for example is great when applied to resources like host CPU Memory, or caches. Whats next These topics were covered in the latest Rancher and Weaveworks webinar where we showed you how to monitor and troubleshoot a service with Weave Cloud that was deployed through Rancher. To get right to using Rancher and Weaveworks together, you can also view just the demo from the webinar online as well.

Many Believe Theres a Prometheus Engineer in Blade Runner 2. Trailer. Another crazy fan theory This one actually holds some water. Its interesting that both Ridley Scotts Alien Covenant and Denis Villeneuves Blade Runner 2. Ridley Scott films Alien was released in 1. Blade Runner came along in 1. The two sci fi classics deal with the idea of androids, and there are various little Easter eggs throughout Scotts work that suggest they may actually exist within the same universe. For example, eagle eyed fans noticed years back that a bonus feature attached to Prometheus, plucked from Peter Weylands diary, seems to link Weyland to Eldon Tyrell, the Blade Runner character responsible for creating the ReplicantsI bring up this fun little connection because many fans this week believe they spotted an Engineer from Alien prequel Prometheus in the new Blade Runner 2. Towards the beginning of the trailer, we see several humanoid like beings in glass cases, presumably inside the walls of the Tyrell Corporation and one of them sure looks a whole hell of a lot like an Engineer. Check out the potential Easter egg at the 1. What does this all meanPerhaps nothing. But given the pre existing connections between the Alien and Blade Runner universes, this sure is an interesting little similarity worth noting. East West Bank Card Activation on this page.
