...when initialising eBPF-based connection tracking. Previously we were ignoring all eBPF events until we had gathered the existing connections. That means we could a) miss connections created during the gathering, and b) fail to forget connections that got closed during the gathering. The fix comprises the following changes: 1. pay attention to eBPF events immediately. That way we do not miss anything. 2. remember connections for which we received a Close event during the initalisation phase, and subsequently drop gathered existing connections that match these. That way we do not erroneously consider a gathered connection as open when it got closed since the gathering. 3. drop gathered existing connections which match connections detected through eBPF events. The latter typically have more / current metadata. In particular, PIDs can be missing from the former. Fixes #2689. Fixes #2700.
Weave Scope - Troubleshooting & Monitoring for Docker & Kubernetes
Weave Scope automatically generates a map of your application, enabling you to intuitively understand, monitor, and control your containerized, microservices based application.
Understand your Docker containers in real-time
Choose an overview of your container infrastructure, or focus on a specific microservice. Easily identify and correct issues to ensure the stability and performance of your containerized applications.
Contextual details and deep linking
View contextual metrics, tags and metadata for your containers. Effortlessly navigate between processes inside your container to hosts your containers run on, arranged in expandable, sortable tables. Easily to find the container using the most CPU or memory for a given host or service.
Interact with and manage containers
Interact with your containers directly: pause, restart and stop containers. Launch a command line. All without leaving the scope browser window.
Extend and customize via plugins
Add custom details or interactions for your hosts, containers and/or processes by creating Scope plugins; or just choose from some that others have already written at the Github Weaveworks Scope Plugins organization.
Getting started
sudo curl -L git.io/scope -o /usr/local/bin/scope
sudo chmod a+x /usr/local/bin/scope
scope launch
This script downloads and runs a recent Scope image from Docker Hub.
Now, open your web browser to http://localhost:4040. (If you're using
boot2docker, replace localhost with the output of boot2docker ip.)
For instructions on installing Scope on Kubernetes, DCOS or ECS, see the docs.
