mod_measure_process: Report the enforced limit The soft limit is what the kernel actually enforces, while the hard limit is is how far you can change the soft limit without privileges. Unless the process dynamically adjusts the soft limit, knowing the hard limit is not as useful as knowing the soft limit. Reporting the soft limit and the number of in-use FDs allows placing alerts on expressions like 'process_open_fds / process_max_fds >= 0.95'

summary: Prototype MAM summary
---

This is a prototype for an experimental archive summary API recently
added in [Prosody trunk](https://hg.prosody.im/trunk/rev/2c5546cc5c70).

# Protocol

::: {.alert .alert-danger}
This is not a finished protocol, but a prototype meant for testing.
:::

A basic query:

``` {.xml}
<iq id="lx7" type="get">
  <summary xmlns="xmpp:prosody.im/mod_map"/>
</iq>
```

Answered like:

``` {.xml}
<iq type="result" id="lx7">
  <summary xmlns="xmpp:prosody.im/mod_map">
    <item jid="juliet@capulet.lit">
      <count>3</count>
      <start>2019-02-25T15:48:00+0100</start>
      <end>2019-08-23T01:39:50+02:00</end>
      <body>O Romeo, Romeo! wherefore art thou Romeo?</body>
    </item>
  </summary>
</iq>
```

It can also take dataform and RSM parameters similar to a [filtered MAM
query](https://xmpp.org/extensions/xep-0313.html#filter).

E.g if the last message you received had an id `09af3-cc343-b409f` then
the following query would tell you who sent you messages since:

``` {.xml}
<iq id="lx8" type="get">
  <summary xmlns="xmpp:prosody.im/mod_map">
    <set xmlns="http://jabber.org/protocol/rsm">
      <max>10</max>
      <after>09af3-cc343-b409f</after>
    </set>
  </summary>
</iq>
```
