Hipache Health-Checker

This is an active health-checker for the Hipache proxy solution. The checker will check the backends at a regular interval and it will update Hipache's Redis to mark them as dead (or alive) almost instantly.

1. Compile

---

go build

2. Run it

---

./hchecker

It connects on the local redis (localhost:6379), so it's supposed to be run on the same machine than Hipache.

3. Modify the behavior

---

./hchecker -h
Usage of ./hchecker:
  -connect=3: TCP connection timeout (seconds)
  -cpuprofile=false: Write CPU profile to "hchecker.prof" (current directory)
  -dryrun=false: Enable dry run (or simulation mode). Do not update the Redis.
  -host="ping": HTTP host header
  -interval=3: Check interval (seconds)
  -io=3: Socket read/write timeout (seconds)
  -method="HEAD": HTTP method
  -redis="localhost:6379": Network address of Redis
  -redis_password="": Password of Redis
  -uri="/CloudHealthCheck": HTTP URI

4. Run the tests

---

$ cd test ; python -m unittest discover
