README

Services declared as oneshot are expected to take some action and exit immediatelly (thus, they are not really services, no running processes remain). A common pattern for these type of service is to be defined by a setup and a teardown action.

Let's create a example foo service that when started creates a file, and when stopped it deletes it.

Define setup/teardown actions

Create executable file /opt/foo/setup-foo.sh:

hofnerb

git init <repo>
cd <repo>
git remote add -f origin <url>

This creates an empty repository with your remote, and fetches all objects but doesn't check them out. Then do:

git config core.sparseCheckout true

import socket
def collect_metric(name, value, timestamp):
    sock = socket.socket()
    sock.connect( ("localhost", 2003) )
    sock.send("%s %d %d\n" % (name, value, timestamp))
    sock.close()

def now():
    return int(time.time())
