# ultradns\_probe\_http

Provides an UltraDNS HTTP probe

## Example Usage
```
resource "ultradns_probe_http" "probe" {
  zone  = "${ultradns_tcpool.pool.zone}"
  name  = "${ultradns_tcpool.pool.name}"
  pool_record = "10.2.1.1"

  agents = ["DALLAS", "AMSTERDAM"]

  interval  = "ONE_MINUTE"
  threshold = 1

  http_probe {
    transaction {
      method           = "POST"
      url              = "http://localhost/index"
      transmitted_data = "{}"
      follow_redirects = true

      limit {
        name = "run"

        warning  = 1
        critical = 2
        fail     = 3
      }
      limit {
        name = "avgConnect"

        warning  = 4
        critical = 5
        fail     = 6
      }
      limit {
        name = "avgRun"

        warning  = 7
        critical = 8
        fail     = 9
      }
      limit {
        name = "connect"

        warning  = 10
        critical = 11
        fail     = 12
      }
    }

    total_limits {
      warning  = 13
      critical = 14
      fail     = 15
    }
  }
}
