How to create a topology?

[jannick_deturck]

In extensions framework I can't use groups and devices any more.

Therefor I need to create a topology for the definition here below that I need to add in the extension.yaml file 

 # report device metrics from the API

    def reportDeviceMetrics(self, session):

        # Create group - provide group id used to calculate unique entity id in dynatrace

        #   and display name for UI presentation

        group = self.topology_builder.create_group(identifier=self.unifisitename,

                                                   group_name=self.unifisitedesc)

        response = session.get(

            url="{}/api/s/{}/stat/device".format(self.url, self.unifisitename),

            headers = self.headers,

            verify = False,

            timeout = 1

        )

        if response.status_code != 200:

            logger.error("Exception happened during device-basic api call = " + resp.text)

        devices = response.json().get("data")

        for device in devices:

            print(device.get("name"))

            # Create device - provide device id used to calculate unique entity id in dynatrace

            #   and display name for UI presentation

            node = group.create_device(identifier="unifi-device-{}".format(device.get("name")), display_name=device.get("name"))

            logger.info("Topology: group name=%s, device name=%s", group.name, node.name)

            # report property - any string-string values pair. It is added to device metadata displayed in dynatrace UI

            node.report_property(key='mac', value=device.get('mac'))

            node.report_property(key='disabled', value=str(device.get('disabled')))

            node.report_property(key='adopted', value=str(device.get('adopted')))

            node.report_property(key='type', value=device.get('type'))

            node.report_property(key='model', value=device.get('model'))

            # report state - value must be one from list located in json file.

            devicestate = 'OFF'

            if device.get('state') == 1:

                devicestate = 'ON'

            node.state_metric(key='state', value=devicestate)

            systemStats = device.get('system-stats')

            if systemStats is not None:

                node.absolute(key='sys-cpu', value=float(systemStats.get("cpu")))

                node.absolute(key='sys-memory', value=float(systemStats.get("mem")))


Anybody an idea how to do that?

In Extension Framework 2 the way to define topology changed completely. You now need to define your topology in the extension.yaml file to match the metrics you are sending from your code.

Have a look at this thread for an example and explanation on how you could do it.

Thanks for this example,  but I was already aware that we need to add a topology in the extension.yaml file.

My question is HOW I can do this?

topology:

  types:

    - enabled: true

      name:

      displayName:

      rules:

        - idPattern:

          instanceNamePattern:

          iconPattern:

          sources:

            - sourceType: Metrics

              condition: ()

          role: default
