Services, resources, tosca type definitions, users etc are all stored by SDC in a janusgraph DB in the sdctitan table in the cassandra DB. The following details how the information stored in the janusgraph can be viewed
- Run janusgraph server
- This docker-compose file can be used to start up a janusgraph server can then be used to read from the DB
- set your ip address in the docker-compose file
- docker-compose -f docker-compose-cql-es.yml up
- Start gemlin
- Login to the janusgraph server
- docker exec -it jce-janusgraph bash
- Start gremlin
- bin/gremlin.sh
- Read
- Connect to the graph
- :remote connect tinkerpop.server conf/remote.yaml
- Use gremlin query commands to execute queries to the DB, for example (note the ":>" is part of the command):
- :> g.V() - list all vertices
- :> g.V().has('name', 'myService') - list vertices with name 'myService'
- :> g.V().has('name', 'myService').valueMap() - show details of vertices with name 'myService'
- :> g.V().has('name', 'myService').properties() - properties of vertices with name 'myService'
- :> g.V().has('name', 'myService').properties('metadata').value() - value of the property "metadata" of vertices with name 'myService'
- :> g.V().has('nodeLabel', 'dataType') - data type vertices
- :> g.V().has('nodeLabel', 'dataType').count() - total of data type vertices
- :> g.V().has('name', 'ericsson.datatypes.nfv.InstantiateVnfOperationAdditionalParameters').properties()
- node types (VFCs)
- All node types
- :> g.V().has('nodeLabel', 'node_type')
- All nodes that derives from tosca.nodes.Root
- :> g.V().has('nodeLabel', 'node_type').has('toscaResourceName', 'tosca.nodes.Root').in('DERIVED_FROM')
- model
- Model with given name
- :> g.V().has('name', 'ETSI SOL001 v2.5.1')
- Model with given id
- :> g.V().has('uid', 'model.ETSI SOL001 v2.5.1')
- All models
- :> g.V().has('nodeLabel', 'model')
- All Service Templates (Service, VF, PNF, etc.) that is associated to the model
- :> g.V().has('uid', 'model.ETSI SOL001 v2.5.1').out('MODEL_ELEMENT').has('nodeLabel', 'topology_template')
- Export
- The entire graph can be exported for viewing with a compatible tool by using the following gremlin command which exports to a file with the given name
- :> graph.io(graphml()).writeGraph("export.xml")
- View
- Cytoscape can be used to view the exported graph. It can be downloded from:
- Once running, select the below to import the graph:
