Spectrum device count different to DX OI

Products

• DX Operational Intelligence

Issue/Introduction

 

When creating a service choosing Monitoring domain: Network and Base Attribute: Device Name, there are 1505 devices available. In Spectrum there are 5500 devices.

 

Checking a few random devices missing in DX OI, they are listed in the Spectrum DataPublisher topology log.

It seems the DataPublisher get all devices from Spectrum, but not all are then transferred to DX OI.

Resolution

 

 

Check the amount of devices listed in Spectrum >Locator Search > All devices

Compare this with the output of devices in OI inventory store from Spectrum using this filter to query:

{

   "filter": {  

    "op": "TAKE_VERTICES",

    "input": { 

      "op": "LAYER",

      "value": "NETWORK_SPECTRUM"

    }

  },

}

 

Example, at the end of the response totalVertices count will be shown, please check if this count is matching with Spectrum - Locator Search - All devices
