Eavesdropper

Motivation

We wanted the ability for a node to join a cluster and monitor the logs of all the nodes in the cluster without adding anything as a dependency.

Installation

It's available on Hex, the package can be installed as:

Installing and configuring the receiving application

1. add :eavesdropper to your dependencies

   def deps do
   [
    {:eavesdropper, "~> 0.0.1"}
   ]
   end

2. add to the application tree

   {Eavesdropper.Receiver, []},
   {Eavesdropper.LogForwarder, []}

3. Add configs

   config :eavesdropper,
   receiving_node: "earth@127.0.0.1", # name of the node that will receive the logs
   min_level: :error, # The minimum level of logs to be forwarded
   truncate: 4096 # max of logs (default is what Logger is defaulted to)

4. Once connected to a node run Eavesdropper.start_eavesdropping(node_name) to start seeing the logs from the target node
5. To stop eavesdropping on a target node run Eavesdropper.stop_eavesdropping(node_name)
