<p>An error record represents one error event,
captured by Elastic APM agents within one service.
It is identified by a unique ID.
An error event contains at least
information about the original <code class="literal">exception</code> that occured
or information about a <code class="literal">log</code> that was created when the exception occured.</p>
<p>Both the captured <code class="literal">exception</code> and the captured <code class="literal">log</code> of an error can contain <code class="literal">stack trace</code> information,
helpful for debugging an error.</p>
<p>The <code class="literal">culprit</code> of an error gives some information about the origin of the error.</p>
<p>An error can be mapped to the <a class="xref" href="transactions.html" title="Transactions">transaction</a> during which it happened,
via the <code class="literal">transaction.id</code>.</p>
<p>An event&#8217;s context bundles information regarding the environment in which it is recorded.
It describes the <code class="literal">service</code> in which the event is captured,
the <code class="literal">system</code> in which the monitored service is running and the event&#8217;s <code class="literal">process</code> information.</p>
<p>It can also contain information about the authenticated <code class="literal">user</code>.</p>
<p>An event&#8217;s context can also include information about the request leading to the event and the response of processing the event.
In case a http request is captured, it contains information about the <code class="literal">url</code>, <code class="literal">cookies</code>, <code class="literal">body</code>, <code class="literal">headers</code>, etc.</p>
<p>The agents provide some configuration options with which the users can also capture customized information.
The non-indexed information is captured within a <code class="literal">custom</code> object,
while the searchable information is stored within <code class="literal">tags</code>.</p>
