mod_smacks: Fix traceback due to session being destroyed in send() Sending something can cause the OS to notice that the connection is dead and then the connection can be dead at this point. More likely if opportunistic_writes is enabled.

summary: Host status heartbeat
...

Introduction
============

This module integrates with [mod\_host\_status\_check] to provide heartbeats at regular intervals.

The only time you will generally want this, is if you are using [mod\_component\_client] to run Prosody as
an external component of another Prosody server that has [mod\_host\_status\_check] loaded and waiting for
heartbeats.

Alternatively you can run this on the same Prosody host as [mod\_http\_host\_status\_check] and it will simply
update a variable periodically to indicate that Prosody and timers are functional.

Configuration
=============

The following configuration options are supported:

```{.lua}
-- The number of seconds to wait between sending heartbeats
status_check_heartbeat_interval = 5

-- Set this to "remote" (the default) if you are using mod_component_client
-- and you want to send a heartbeat to a remote server. Otherwise
-- set it to "local" to send to mod_host_status_check on the same server.
status_check_heartbeat_mode = "remote"
```

Compatibility
=============

Works with Prosody 0.9.x and later.
