Dead man's switch (server)

This module receives status messages by dead_mans_switch_client and notifies you if a client instance didn't check back in time.

As a side effect, you'll also get some statistical data from your client instances.


Install dead_mans_switch_client on a customer instance and configure it as described in that module's documentation. The clients will register themselves with the server automatically. They will show up with their database uuid, you'll have to assign a human readable description yourself.

At this point, you can assign a customer to this client instance for reporting purposes, and, more important, add followers to the instance. They will be notified in case the instance doesn't check back in time. Notification are only turned on for instances in state 'active', instances in states 'new' or 'suspended' will be ignored.

You'll find the instances' current state at Reporting/Customer instances.

Security considerations

As the controller receiving status updates is unauthenticated, any internet user can have your server create monitoring instance records. While this is annoying, it's quite harmless and basically the same as misuse of the fetchmail module.

For a more substantial annoyance, the attacker would have to guess one of your client's database uuids, so they functionally are your passwords.

To be sure, consider blocking this controller from unknown origins in your SSL proxy. In nginx, it would look like this:

location /dead_mans_switch/alive {
# add other client's IPs
deny    all;

Known issues / Roadmap

  • matching is done via the database's uuid, so take care to change this if you clone a database
  • logging some postgres stats and disk usage would be nice too
