Tom Wilkie shares Weaveworks monitoring philosophy and the three most important metrics to use in your microservices architecture.

WebSockets Are Evil and Must Die

In previous blog posts I’ve mention my dislike for WebSockets. In this quick blog post I attempt to explain why. Unfortunately I think this raises more questions than it answers!Be aware, these opinions are my own.It’s the monitoring,...

Weave Cloud UI Alerts and Metrics

After a particularly egregious outage was reported by a Weave Cloud user, we decided it would be a good idea to add some alerting to our front-end codebase. Alerting and metrics for Weave Cloud are handled using Prometheus, however, which...

Introduction to Prometheus Monitoring

Prometheus monitoringPrometheus is open source monitoring software that treats time series data as a data source for generating precise alerts. Now part of the Cloud Native Computing Foundation, the project began at SoundCloud in 2012. As...

PromQL queries for the rest of us

Prometheus comes with its own query language called PromQL. It’s very powerful and easily allows you to filter with the multi-dimensional time-series labels that make Prometheus so great. But it can be daunting when you are faced with an...

Improving performance and reliability in Weave Scope with eBPF

As a cloud monitoring tool, Weave Scope has to collect data about processes and network connections on each cluster node, process that data, and compile everything into a report that is sent to the app server as data points for the user...

Of Metrics and Middleware

The topic of how the services in Weave Cloud are instrumented came up in two discussions this week, so I thought I’d write a short blog post explaining all the moving parts.Instrumenting RequestsFor all services in Weave Cloud, we measure...

Log Aggregation for Kubernetes with Loggly

I consider log aggregation to be one of “pillars” of observability – a crucial service that every developer needs when working with distributed apps / microservices / cloud natives. In this post I’ll explain how we uses Loggly to aggregate...

Weave Cloud Outage 28th Feb Post-Mortem

Weave Cloud is our service for deploying, exploring, and monitoring microservice-based applications. At 17:37 GMT on 28th Feb, Weave Cloud suffered an outage for over 4 hours. The expectation of availablilty on a service like Weave Cloud...

Running Consul on Kubernetes and Monitoring it With Prometheus

We run a couple of replicated Consul services for Weave Cloud: one acts as a coordinator for the distributed WebSocket router backing Scope’s terminals feature, and the other for storing the state of Cortex’s consistent hash ring. This...

Aggregating Pod resource (CPU, memory) usage by arbitrary labels with Prometheus

How would you answer the questions like “how much CPU is my service consuming?” using Prometheus and Kubernetes? In this quick post, I’ll show you how…First we need to think about where to get the information from. cAdvisor (from Google)...

Cloud Provider Options for a Container-Friendly Environment

The advent Docker and containers, has simplified packaging, deploying and supporting applications. However, with this advancement come challenges, as you also need a robust environment in which to deploy the containers. And that requires...

Weave Mesh in Prometheus Alertmanager

tl;dr: Weave Mesh, an open-source gossip and CRDT communications library, gave the Prometheus Alertmanager exactly what it needed to be reliable and highly-available.As a former SoundCloud engineer, I’ve had the privilege of using...

Monitoring Your Kubernetes Infrastructure with Prometheus

In the last post in our series “Prometheus and Kubernetes”, Tom talked about how we use Prometheus to monitor the applications and services we deploy to Kubernetes. In this post, I want to talk about how we use Prometheus to monitor our...
