GitHub - tpiha/gocheck: Go server cloud checks

High performance server cloud checks written in Go. Gocheck is easily extensible through the JSON file (definitions.json).

Usage of gocheck:
  -c uint
        Concurrency; how many parallel connections to make (default 5)
  -d string
        Name of the checks definitions JSON file (default "definitions.json")
  -f string
        Name of the checks JSON file (default "checks.json")
  -s string
        Name of the servers JSON file (default "servers.json")
  -v    Show verbose output

Adding check definitions

For example, if you want to make sure your servers root partitions have more than 1GB of free space, you would add this to the definitions.json file:

    {
        "name": "free_space",
        "command": "test $(df $PWD | awk '/[0-9]%%/{print $(NF-2)}') -gt %s",
        "args": ["kilobytes"]
    }

And then, to actually do the test on your servers, you need to create a check adding it in checks.json file like this:

    "check_free_space": {
        "type": "free_space",
        "kilobytes": "1000000"
    }
