Skydive

Skydive is an open source real-time network topology and protocols analyzer. It aims to provide a comprehensive way of understanding what is happening in the network infrastructure.

Skydive agents collect topology information and flows and forward them to a central agent for further analysis. All the information is stored in an Elasticsearch database.

Skydive is SDN-agnostic but provides SDN drivers in order to enhance the topology and flows information.

Key features

  • Captures network topology and flows
  • Full history of network topology and flows
  • Distributed
  • Ability to follow a flow along a path in the topology
  • Supports VMs and Containers infrastructure
  • Unified query language for topology and flows (Gremlin)
  • Web and command line interfaces
  • REST API
  • Easy to deploy (standalone executable)
  • Connectors to OpenStack, Docker, OpenContrail, Kubernetes

Quick start

All-in-one

The easiest way to get started is to download the latest binary and to run it using the all-in-one mode :

curl -Lo - https://github.com/skydive-project/skydive-binaries/raw/jenkins-builds/skydive-latest.gz | gzip -d > skydive && chmod +x skydive && sudo mv skydive /usr/local/bin/

SKYDIVE_ETCD_DATA_DIR=/tmp SKYDIVE_ANALYZER_LISTEN=0.0.0.0:8082 sudo -E /usr/local/bin/skydive allinone

Open a browser to http://localhost:8082 to access the analyzer Web UI.

Helm

If you are using Kubernetes then you can deploy skydive using helm directly from Git:

helm plugin install https://github.com/aslafy-z/helm-git --version 0.10.0
helm repo add skydive git+https://github.com/skydive-project/skydive@contrib/charts
helm repo update
helm install skydive-analyzer skydive/skydive-analyzer
helm install skydive-agent skydive/skydive-agent
kubectl port-forward service/skydive-analyzer 8082:8082

Open a browser to http://localhost:8082 to access the analyzer Web UI.

Docker

docker run -d --privileged --pid=host --net=host -p 8082:8082 -p 8081:8081 \
    -e SKYDIVE_ANALYZER_LISTEN=0.0.0.0:8082 \
    -v /var/run/docker.sock:/var/run/docker.sock -v /run/netns:/var/run/netns \
    skydive/skydive allinone

Open a browser to http://localhost:8082 to access the analyzer Web UI.

Docker Compose

To quick set up a more complete working environment (with history support), Docker Compose can be used to automatically start an Elasticsearch container, a Skydive analyzer container and a Skydive agent container.

curl -o docker-compose.yml https://raw.githubusercontent.com/skydive-project/skydive/master/contrib/docker/docker-compose.yml
docker-compose up

You can also use the Skydive command line client with:

docker run --net=host -ti skydive/skydive client query "g.V()"

Open a browser to http://localhost:8082 to access the analyzer Web UI.
