I have been researching on Microsoft Azure Event Hubs. My goal is to figure out a way to provide automatic scalability. This is a experimental work and I am really only trying to know what can I do with Azure event hubs. I do not have access to the Azure platform to test test anything :( .
Well, so far, I found that through REST API and Service Bus Powershell I can add Throughput Units (to increase performance - I am relying on this: Scale Azure Service Bus through Powershell or API) and increase or decrease Event's Expiration time (which might influence capacity - https://msdn.microsoft.com/en-us/library/azure/dn790675.aspx).
The problem is that, presuming that the previous techniques work and I am able to scale event hubs' performance automatically, I still need a way to know when to trigger scalability mechanisms. To know when and how to trigger scalability, I need to work on some functions that rely upon the event hub's metrics (or a way to monitoring it). The problem is that I can't really find any metrics. The only thing that I find is this: https://azure.microsoft.com/en-us/documentation/articles/cloud-services-how-to-monitor/ - Which actually does not solve my problem because although it may present some interesting metrics, it does not serve the purposes of my "application" (which will come if I can prove that I can successfully scale Azure automatically); and this Azure service bus statistics/Monitoring - which's links are not working.
Surely I can find more information about Service Bus Explorer, and surely it may provide some interesting insights over the event hub metrics, I am just wondering if there is something like this: https://github.com/HBOCodeLabs/incubator-storm/blob/master/STORM-UI-REST-API.md that allow me to access some kind of metrics, rather than creating my own metrics
Thanks in advance Best regards
