Disturbance

Monitor disturbances in a web service's behaviour.

You may use disturbance as a monitoring utility which is up over an extended period of time to know if a service ever went down/unhealthy. Eg: Uptime during a deployment.

Usage

``` USAGE: disturbance [OPTIONS]

FLAGS: -h, --help Prints help information -V, --version Prints version information

OPTIONS: -e, --excludes Response should not match -m, --matches Response should match -p, --parallelism Parallelism [default: 2] -t, --timeout Request timeout in seconds [default: 5] -w, --wait Wait time (in ms) between requests per worker. [default: 100]

ARGS: The web service's URL to monitor`` ```

Example

• Check a website's response distribution to simple GET requets. $ disturbance https://example.com/ Success(200) => 14

• Check a website while also requring a pattern to be present.
  With a pattern that isn't present in the responses: $ disturbance https://example.com/ -m test DoesNotMatch => 407 With intermittent matches (potentially unstable website): $ disturbance https://example.com/ -m true Success(200) => 64, DoesNotMatch => 10

• Use an exlusion pattern, to ensure that responses never contain the string that you paas. $ disturbance https://example.com/ -e '"success":false' DoesNotExclude => 12 Or a good service: $ disturbance https://example.com/ -e '"success":true' Success(200) => 18

• Configure parallelism to control the number of parallel workers (defaults to 2). $ disturbance https://example.com/ -p 4 Success(200) => 128

• Set a custom timeout in seconds (default 5) $ disturbance https://example.com/ -t 1 ErrorResponse("https://example.com/: timed out") => 4

• Set a custom wait time between requests (default: 100 ms), per worker. If you want $ disturbance https://example.com/ -t 1 -w 500 ErrorResponse("https://example.com/: timed out") => 4
