mod_prometheus: Invoke stats collection if in 'manual' mode Since 10d13e0554f9 a special value for statistics_interval "manual" exists, where a module is expected to invoke processing in connection to collection of stats. This makes internal collection and exporting to Prometheus happens at the same time with no chance of timers getting out of sync.

summary: prosodyctl cross storage driver migration tool
...

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

This module adds a command to `prosodyctl` for copying data between
storage drivers.

Usage
=====

    prosodyctl mod_migrate example.com <source-store>[-<store-type>] <target-driver> [users]*

`<source-store>` would be e.g. `accounts` or `private`. To migrate
archives, the optional suffix `<store-type>` would be set to `archive`,
so e.g. `archive2-archive` or `muc_log-archive`. Multiple stores can be
given if separated by commas.

`<target-driver>` is the storage driver to copy data to, sans the
`mod_storage_` prefix.

`mod_migrate` tries to request a list of users from `usermanager`, but
this does not always work. If so, you can supply usernames as arguments
after the target driver.

The process is something like this:

1.  Decide on the future configuration and add for example SQL
    connection details to your prosody config, but don't change the
    `store` option yet.
2.  With Prosody shut down, run
    `prosodyctl mod_migrate example.com accounts sql`
3.  Repeat for each store, substituting 'accounts'. E.g. vcards,
    private...
4.  Change the [`storage` configuration](https://prosody.im/doc/storage)
    to use the new driver.
5.  Start prosody again.

Examples
========

``` sh
prosodyctl mod_migrate example.com accounts,roster,private,vcard sql
```

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

Should work with 0.8 and later.
