Subscriptions-CLI

This is a simple command line utility for subscribing to telemetry events from the capsule8 sensor

The telemtry cli takes one argument: a path to a subscription file. Subscriptions are a high level object used by clients to the telemetry service in the sensor for receiving telemetry events. These files are simply subscription structs marshalled to JSON. The subscriptions directory contains a few examples. Also check out the doc for getting telemetry for an in-depth view of how this works.

If you write a subscription file that you think others would find useful, feel free to contribute it!

Quickstart

1. Build and run the capsule8 sensor

2. Build this example tool by running make

3. Run the tool by passing a JSON subscription file located in subscriptions (You will need to run this as root)

$ sudo ./c8cli subscriptions/ContainerEvents.json
