mod_sasl2_fast: Fix harmless off-by-one error (invalidates existing tokens!) Problem: This was causing the key to become "<token>--cur" instead of the expected "<token>-cur". As the same key was used by the code to both set and get, it still worked. Rationale for change: Although it worked, it's unintended, inconsistent and messy. It increases the chances of future bugs due to the unexpected format. Side-effects of change: Existing '--cur' entries will not be checked after this change, and therefore existing FAST clients will fail to authenticate until they attempt password auth and obtain a new FAST token. Existing '--cur' entries in storage will not be cleaned up by this commit, but this is considered a minor issue, and okay for the relatively few FAST deployments.

summary: Collect statistics on rate of log messages
...

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

If you ever wanted to collect statistics on the number of log messages,
this is the module for you!

Setup
=====

After [installing the module](https://prosody.im/doc/installing_modules)
and adding it to modules\_enabled as most other modules, you also need
to add it to your logging config:

``` {.lua}
log = {
  -- your other log sinks
  info = "/var/log/prosody/prosody.log"
  -- add this:
  { to = "measure" };
}
```

Then log messages will be counted by
[statsmanager](https://prosody.im/doc/developers/core/statsmanager).

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

Reqires Prosody 0.10 or above.
