|
||
Attributes are named and typed pieces of metadata describing ingress and egress traffic and the
|
||
environment this traffic occurs in. An Istio attribute carries a specific piece
|
||
of information such as the error code of an API request, the latency of an API request, or the
|
||
original IP address of a TCP connection. For example:</p><pre><code class=language-yaml>request.path: xyz/abc
|
||
request.size: 234
|
||
request.time: 12:34:56.789 04/17/2017
|
||
source.ip: 192.168.0.1
|
||
target.service: example
|
||
</code></pre><p>A given Istio deployment has a fixed vocabulary of attributes that it understands.
|
||
The specific vocabulary is determined by the set of attribute producers being used
|
||
in the deployment. The primary attribute producer in Istio is Envoy, although
|
||
specialized Mixer adapters and services can also generate attributes.</p><p>The common baseline set of attributes available in most Istio deployments is defined
|
||
<a href=/v1.5/docs/reference/config/policy-and-telemetry/attribute-vocabulary/>here</a>.</p><p>Attributes are strongly typed. The supported attribute types are defined by
|
||
<a href=https://github.com/istio/api/blob/release-1.5/policy/v1beta1/value_type.proto>ValueType</a>.
|
||
Each type of value is encoded into one of the so-called transport types present
|
||
in this message.</p><p>Defines a map of attributes in uncompressed format.

Following places may use this message:
|
||
1) Configure Istio/Proxy with static per-proxy attributes, such as source.uid.
|
||
2) Service IDL definition to extract api attributes for active requests.
|

3) Forward attributes from client proxy to server proxy for HTTP requests.</p><table class=message-fields><thead><tr><th>Field</th><th>Type</th><th>Description</th><th>Required</th></tr></thead><tbody><tr id=istio-mixer-v1-Attributes-attributes><td><code>attributes</code></td><td><code>map<string, <a href=#istio-mixer-v1-Attributes-AttributeValue>AttributeValue</a>></code></td><td><p>A map of attribute name to its value.</p></td><td>No</td></tr></tbody></table></section></article><nav class=pagenav><div class=left><a title="Default Metrics exported from Istio through Mixer." href=/v1.5/docs/reference/config/policy-and-telemetry/metrics/><svg class="icon"><use xlink:href="/v1.5/img/icons.svg#left-arrow"/></svg>Default Metrics</a></div><div class=right><a title="Describes the rules used to configure Mixer's policy and telemetry features." href=/v1.5/docs/reference/config/policy-and-telemetry/istio.policy.v1beta1/>Rules<svg class="icon"><use xlink:href="/v1.5/img/icons.svg#right-arrow"/></svg></a></div></nav><div id=feedback><div id=feedback-initial>Was this information useful?<br><button class="btn feedback" onclick="sendFeedback('en',1)">Yes</button>
