Nodestat

Nodestat is a tool that allows you to easily gather statistics about your cjdns node. It currently presents a very simple HTTP JSON API for getting information.

Nodestat is currently undergoing heavy development and as such the structure, format, and content of the data it provides is subject to change at any time.

Installation

To install nodestat, run go get github.com/inhies/nodestat. You will need to create a configuration file. Simply copy the sample file to nodestat.conf and place it in the same directory as your nodestat executable.

To run nodestat, change to it's directory with cd $GOPATH/src/github.com/inhies/nodestat, build it with go build, and run it with ./nodestat.

Usage

By default, nodestat will present three endpoints:

• /node Gives you information regarding cjdns itself
• /peers Gives you information regarding your connected peers
• /all Combines node and peers output

Example Output

The following sections show the output of the /peers and /node HTTP JSON API endpoints, respectively.
