A (dead-simple) Golang utility allowing you to monitor HTTP endpoints

Go-mon

This small utility is dead simple and will allow you to monitor HTTP endpoints, and easily pluggable in the CI. Everything is configurable through a YAML file (monitor.yml) and looks like this:

insecure: false
timeout_seconds: 5
checks:
  - url: "https://www.cfptime.org"
    status_code: 200
    match: "Loading"
    response_time: 210
  - url: "https://shodan.io/"
    status_code: 200
    match: "the Internet of Things"

Options

Option	What does it mean
insecure	Skip SSL/TLS verification (in case of self-signed certificates, ..)
timeout_seconds	How long you'd like to wait for the HTTP request
checks	A list of all the checks you'd like to perform
checks > url	The URL you want to monitor
checks > status_code	The status code you expect
checks > match	One string you're looking for on the webpage

Usage

In order to launch it, just build it and run it this way:

$ go build main.go && ./main
[OK] https://www.cfptime.org
[OK] https://shodan.io/
$ echo $?
0

If you add another check that will obviously fail:

  - url: "https://urlthatdoesnotexist.foobar"
    status_code: 500
    match: "the Internet of Things"

Resulting output will be:

$ ./main
[OK] https://www.cfptime.org
[OK] https://shodan.io/
[NOK] https://urlthatdoesnotexist.foobar
$ echo $?
1
