Automatically generate a sequence diagram from JSON of Trace in Datadog.

⚠️ Only gRPC calls appear in the sequence diagram.

Example

w/ response

"v2-service": Ping Request "v2-service" -> "v3-service": Pong Request "v2-service" <-- "v3-service": Pong Response "v1-service" <-- "v2-service": Ping Response @enduml ">

$ jigsaw -config ./example/config.yaml ./example/trace.json
@startuml
"v1-service" -> "v2-service": Ping Request
"v2-service" -> "v3-service": Pong Request
"v2-service" <-- "v3-service": Pong Response
"v1-service" <-- "v2-service": Ping Response
@enduml

w/o response

"v2-service": Ping Request "v2-service" -> "v3-service": Pong Request @enduml ">

$ jigsaw -config ./example/config.yaml -no-response ./example/trace.json
@startuml
"v1-service" -> "v2-service": Ping Request
"v2-service" -> "v3-service": Pong Request
@enduml
