Jaeger

Jaeger, inspired by Dapper and OpenZipkin, is a distributed tracing system released as open source by Uber Technologies. It can be used for monitoring microservices-based distributed systems:

  • Distributed context propagation
  • Distributed transaction monitoring
  • Root cause analysis
  • Service dependency analysis
  • Performance / latency optimization

Note: Jaeger requires a minimum of 4 nodes, with 4GB RAM + 2vCPUs, and 40GB of storage.

Software Included

Package Version License
Jaeger 1.17.1 Apache 2
Cassandra 3.11.6 Apache 2

Creating an App using the API

In addition to creating Jaeger using the control panel, you can also use the DigitalOcean API. As an example, to create a 3 node DigitalOcean Kubernetes cluster made up of Basic Droplets in the SFO2 region, you can use the following doctl command. You need to authenticate with doctl with your API access token) and replace the $CLUSTER_NAME variable with the chosen name for your cluster in the command below.

doctl kubernetes clusters create --size s-4vcpu-8gb $CLUSTER_NAME --1-clicks jaeger
