Build Status Coverage Status

Server monitoring tool

Vermont allow you to check your server's state. It can ping urls and exec shell commands.

Usage

Vermont available to use right in JS code and as a CLI application. The both checks (ping and exec) require parameter expected to be specified. It may be a number or a string. Vermont compares different values in order to expected type.

expected ping exec
number response status code exit code
string response body command stdout

For example: if you need to check that url answers 200 status code you should set expected to 200. But if you want to know that url answers 'ok' in its body you may set expected to 'ok'. The exec method works just as well.

NOTE: If type of expected is a string it will be used as a regular expression.

NOTE: If expected parameter is not specified Vermont will use 200 for ping or 0 for exec as default.
