Fire alarms with system events

## Usage

```go

golarm.AddAlarm(golarm.SystemLoad(golarm.OneMinPeriod).Above(0.8).Run(func() {

		fmt.Println("System load >0.8 !!")

		smtp.SendMail(smtpHost, emailConf.Port, "System load >0.8 !!")

	}))

```

![Usage example](http://i.imgur.com/FybUkVg.gif)

## Options

 - SystemLoad

 

 ```go

// checks if the system load is lower or equal to 0.5

golarm.AddAlarm(golarm.SystemLoad(golarm.OneMinPeriod).AboveEqual(0.5).Run(func() {

		fmt.Println("System load >=0.5 !!")

	}))

```

 - SystemUptime

 

  ```go

// checks if the system has been running for less than 1 minute

golarm.AddAlarm(golarm.SystemUptime().Below(1).Run(func() {

		fmt.Println("System just started !!")

	}))

```

 - SystemMemory / SystemSwap [Free, Used]

 

 ```go

// checks if used memory is higher that 90%

golarm.AddAlarm(golarm.SystemMemory().Used().Above(90).Percent().Run(func() {

		fmt.Println("Used system memory > 90% !!")

	}))

```

 ```go

// checks if free memory is lower that 500MB

golarm.AddAlarm(golarm.SystemMemory().Free().BelowEqual(500).Run(func() {

		fmt.Println("Free memory <= 500MB !!")

	}))

```

 - SystemProc [Status, RunningTime, Used (Memory)]

  ```go

// checks if the process 72332 has changed to zombie status

golarm.AddAlarm(golarm.SystemProc(72332).Status(golarm.Zombie).Run(func() {

		fmt.Println("Our process with PID 72332 became Zombie !!")

	}))

```

  ```go

// checks if the process 72332 has been running for more than 20 minutes

golarm.AddAlarm(golarm.SystemProc(72332).RunningTime().Above(20).Run(func() {

		fmt.Println("Our process with PID 72332 exceeded 20 minutes running !!")

	}))

```
