mod_compat_roles: Fix attempt to index a nil value #1847
permissions[] is not a map with role names as keys since 817bc9873fc2
but instead a level with host names were added. This was likely an
oversight.
Refactored towards railroad.

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.
