----

## There is NO perfect failure detector.

## It's a trade-off between completeness and accuracy.

## Failure detection is not a binary value.

This is an implementation of a failure detector that uses
an adaptive accrual algorithm. The theory of this failure detector is taken from the paper
[A New Adaptive Accrual Failure Detector for Dependable Distributed Systems](https://dl.acm.org/citation.cfm?id=1244129).

This failure detector is useful for detecting connections failures between nodes in distributed systems.

## Install

```
go get github.com/andy2046/failured
```

## Usage

```go
package main

import (
"time"

"github.com/andy2046/failured"
)

func main() {
fd := failured.New()
closer := make(chan struct{})

// call RegisterHeartbeat every second
go func() {
for {
select {
case <-closer:
return
default:
}

time.Sleep(time.Second)
fd.RegisterHeartbeat()
}
}()

time.Sleep(3 * time.Second)
close(closer)

// check FailureProbability
p := fd.FailureProbability()
println("failure probability is", p)
}
```
