|
||
(<a href=https://hub.docker.com/r/grafana/grafana/><code>grafana/grafana:5.2.3</code></a>) has been
|
||
modified to start with both a Prometheus data source and the Istio Dashboard
|
||
installed. The base install files for Istio, and Mixer in particular, ship with
|
||
a default configuration of global (used for every service) metrics. The Istio
|
||
Dashboard is built to be used in conjunction with the default Istio metrics
|
||
configuration and a Prometheus backend.</p><p>The Istio Dashboard consists of three main sections:</p><ol><li><p>A Mesh Summary View. This section provides Global Summary view of the Mesh and shows HTTP/gRPC and TCP
|
||
workloads in the Mesh.</p></li><li><p>Individual Services View. This section provides metrics about requests and
|
||
responses for each individual service within the mesh (HTTP/gRPC and TCP).
|
||
This also provides metrics about client and service workloads for this service.</p></li><li><p>Individual Workloads View: This section provides metrics about requests and
|
||
responses for each individual workload within the mesh (HTTP/gRPC and TCP).
|
||
This also provides metrics about inbound workloads and outbound services for this workload.</p></li></ol><p>For more on how to create, configure, and edit dashboards, please see the
|
||
<a href=https://docs.grafana.org/>Grafana documentation</a>.</p><h2 id=cleanup>Cleanup</h2><ul><li><p>Remove any <code>kubectl port-forward</code> processes that may be running:</p><pre><code class=language-bash data-expandlinks=true data-repo=istio>$ killall kubectl
