<h1 id="structured-logging"><a class="header" href="#structured-logging">Structured Logging</a></h1>
|
|
<p>A structured logging system can be useful when your logs are destined for a
|
|
machine to parse and process. By maintaining its machine-readable characteristics,
|
|
it enables more efficient searching and aggregations when consumed by software
|
|
such as the "ELK stack".</p>
|
|
<p>Synapse's structured logging system is configured via the file that Synapse's
|
|
<code>log_config</code> config option points to. The file should include a formatter which
|
|
uses the <code>synapse.logging.TerseJsonFormatter</code> class included with Synapse and a
|
|
handler which uses the above formatter.</p>
|
|
<p>There is also a <code>synapse.logging.JsonFormatter</code> option which does not include
|
|
a timestamp in the resulting JSON. This is useful if the log ingester adds its
|
|
own timestamp.</p>
|
|
<p>A structured logging configuration looks similar to the following:</p>
|
|
<pre><code class="language-yaml">version: 1
|
|
|
|
formatters:
|
|
structured:
|
|
class: synapse.logging.TerseJsonFormatter
|
|
|
|
handlers:
|
|
file:
|
|
class: logging.handlers.TimedRotatingFileHandler
|
|
formatter: structured
|
|
filename: /path/to/my/logs/homeserver.log
|
|
when: midnight
|
|
backupCount: 3 # Does not include the current log file.
|
|
encoding: utf8
|
|
|
|
loggers:
|
|
synapse:
|
|
level: INFO
|
|
handlers: [remote]
|
|
synapse.storage.SQL:
|
|
level: WARNING
|
|
</code></pre>
|
|
<p>The above logging config will set Synapse as 'INFO' logging level by default,
|
|
with the SQL layer at 'WARNING', and will log to a file, stored as JSON.</p>
|
|
<p>It is also possible to figure Synapse to log to a remote endpoint by using the
|
|
<code>synapse.logging.RemoteHandler</code> class included with Synapse. It takes the
|
|
following arguments:</p>
|
|
<ul>
|
|
<li><code>host</code>: Hostname or IP address of the log aggregator.</li>
|
|
<li><code>port</code>: Numerical port to contact on the host.</li>
|
|
<li><code>maximum_buffer</code>: (Optional, defaults to 1000) The maximum buffer size to allow.</li>
|
|
</ul>
|
|
<p>A remote structured logging configuration looks similar to the following:</p>
|
|
<pre><code class="language-yaml">version: 1
|
|
|
|
formatters:
|
|
structured:
|
|
class: synapse.logging.TerseJsonFormatter
|
|
|
|
handlers:
|
|
remote:
|
|
class: synapse.logging.RemoteHandler
|
|
formatter: structured
|
|
host: 10.1.2.3
|
|
port: 9999
|
|
|
|
loggers:
|
|
synapse:
|
|
level: INFO
|
|
handlers: [remote]
|
|
synapse.storage.SQL:
|
|
level: WARNING
|
|
</code></pre>
|
|
<p>The above logging config will set Synapse as 'INFO' logging level by default,
|
|
with the SQL layer at 'WARNING', and will log JSON formatted messages to a
|
|
remote endpoint at 10.1.2.3:9999.</p>
|
|
<h2 id="upgrading-from-legacy-structured-logging-configuration"><a class="header" href="#upgrading-from-legacy-structured-logging-configuration">Upgrading from legacy structured logging configuration</a></h2>
|
|
<p>Versions of Synapse prior to v1.23.0 included a custom structured logging
|
|
configuration which is deprecated. It used a <code>structured: true</code> flag and
|
|
configured <code>drains</code> instead of <code>handlers</code> and <code>formatters</code>.</p>
|
|
<p>Synapse currently automatically converts the old configuration to the new
|
|
configuration, but this will be removed in a future version of Synapse. The
|
|
following reference can be used to update your configuration. Based on the drain
|
|
<code>type</code>, we can pick a new handler:</p>
|
|
<ol>
|
|
<li>For a type of <code>console</code>, <code>console_json</code>, or <code>console_json_terse</code>: a handler
|
|
with a class of <code>logging.StreamHandler</code> and a <code>stream</code> of <code>ext://sys.stdout</code>
|
|
or <code>ext://sys.stderr</code> should be used.</li>
|
|
<li>For a type of <code>file</code> or <code>file_json</code>: a handler of <code>logging.FileHandler</code> with
|
|
a location of the file path should be used.</li>
|
|
<li>For a type of <code>network_json_terse</code>: a handler of <code>synapse.logging.RemoteHandler</code>
|
|
with the host and port should be used.</li>
|
|
</ol>
|
|
<p>Then based on the drain <code>type</code> we can pick a new formatter:</p>
|
|
<ol>
|
|
<li>For a type of <code>console</code> or <code>file</code> no formatter is necessary.</li>
|
|
<li>For a type of <code>console_json</code> or <code>file_json</code>: a formatter of
|
|
<code>synapse.logging.JsonFormatter</code> should be used.</li>
|
|
<li>For a type of <code>console_json_terse</code> or <code>network_json_terse</code>: a formatter of
|
|
<code>synapse.logging.TerseJsonFormatter</code> should be used.</li>
|
|
</ol>
|
|
<p>For each new handler and formatter they should be added to the logging configuration
|
|
and then assigned to either a logger or the root logger.</p>
|
|
<p>An example legacy configuration:</p>
|
|
<pre><code class="language-yaml">structured: true
|
|
|
|
loggers:
|
|
synapse:
|
|
level: INFO
|
|
synapse.storage.SQL:
|
|
level: WARNING
|
|
|
|
drains:
|
|
console:
|
|
type: console
|
|
location: stdout
|
|
file:
|
|
type: file_json
|
|
location: homeserver.log
|
|
</code></pre>
|
|
<p>Would be converted into a new configuration:</p>
|
|
<pre><code class="language-yaml">version: 1
|
|
|
|
formatters:
|
|
json:
|
|
class: synapse.logging.JsonFormatter
|
|
|
|
handlers:
|
|
console:
|
|
class: logging.StreamHandler
|
|
location: ext://sys.stdout
|
|
file:
|
|
class: logging.FileHandler
|
|
formatter: json
|
|
filename: homeserver.log
|
|
|
|
loggers:
|
|
synapse:
|
|
level: INFO
|
|
handlers: [console, file]
|
|
synapse.storage.SQL:
|
|
level: WARNING
|
|
</code></pre>
|
|
<p>The new logging configuration is a bit more verbose, but significantly more
|
|
flexible. It allows for configuration that were not previously possible, such as
|
|
sending plain logs over the network, or using different handlers for different
|
|
modules.</p>
