If you want to use Akamai Cloud Monitor in order to stream your logs in realtime to Sumologic or any other cloud service you have to make sure two things:
1. Make sure you have "Cloud Monitor" as item in your contract
2. Fix the port where you send Cloud Monitor data to
To go into deatils here :
Following the Akamai Implementation guidde for Cloud Monitor (link) you have to set up a dedicated property that forwards the log events, called the "Cloud Monitor Data Delivery Property".
According to the manual you enter the host of Sumologic into the "origin" field of this property. Unluckyly there is a Screenshot telling you to set the ports of this "origin" to 80 & 443. In this case Cloud Monitor will not send data.
To fix this set both ports to 443, after that Cloud Monitor will start sending data.
