servicegraph

Istio Servicegraph ** DEPRECATED. **

Servicegraph is being replaced by Kiali as the default visualization integration.

Servicegraph is a small app that generates and visualizes graph representations of your Istio service mesh. Servicegraph is dependent on the Prometheus addon and the standard metrics configuration. The documentation for deploying and using Servicegraph is here.

Visualizations

• /force/forcegraph.html is an interactive D3.js visualization.

• /dotviz is a static Graphviz visualization.

Serializations

• /dotgraph provides a DOT serialization.

• /d3graph provides a JSON serialization for D3 visualization.

• /graph provides a JSON serialization.

Query Parameters

All endpoints take these query parameters:

• time_horizon controls the timespan to consider for graph generation. Format is a number plus a time unit. Example 15s or 1m. Default is 5m.

• filter_empty=true will restrict the nodes and edges shown to only those that reflect non-zero traffic levels during the specified time_horizon. Default is false.

• destination_namespace will filter the nodes and edges show to only those where the destination workload is in the given namespace.

• destination_workload will filter the nodes and edges show to only those where the destination workload is with the given name.

• source_namespace will filter the nodes and edges show to only those where the source workload is in the given namespace.

• source_workload will filter the nodes and edges show to only those where the source workload is with the given name.

Demosvc service

Defined in servicegraph/cmd/demosvc, this provides a simple HTTP endpoint that generates Prometheus metrics. This can be used to test the servicegraph service.
