Rust implementation of riemann_health.

This is an implementation of riemann_health in rust.

This project uses riemann_client rust plugin (https://github.com/borntyping/rust-riemann_client) version "0.7.0" which contains addition of attributes to event.

The events are currently sent with a delay of 500ms between each event. This is configurable with -d parameter.

Build and Run

To print help menu

cargo build && cargo run -- -h

and the output would be

$ cargo build && cargo run -- -h
    Finished dev [unoptimized + debuginfo] target(s) in 0.0 secs
    Finished dev [unoptimized + debuginfo] target(s) in 0.0 secs
     Running `target/debug/rust-riemann_health -h`
Following is tbe help menu: 

Usage: target/debug/rust-riemann_health [options]

Options:
    -c, --connection [connection]
                        connection string to riemann server in the format
                        <hostname>:<port> . defaults to locahost:5555
    -d, --delay [delay] milliseconds of delay between events. defaults to
                        500ms.
    -h, --help          print help menu
$

To execute without any arguments : ( defaults to localhost:5555 for server connection and 500ms for delay)

cargo run 

or

cargo run -- -c -d 

Execute by passing argument with -c as hostname:port and -d as time in milliseconds Let's say riemann server is running on localhost with port 5555 and you wish to send events with a delay of 1 second Both parameters, connection and delay are optional. Print help to see defaults.

cargo run -- -c localhost:5555 -d 1
