You can send them events but reporting on the events in aggregate is so painful that I'd call it impossible.
Con Lacks an external API
No API for sending information from a mobile application / web backend to analytics.
Con Subpar funnel functionality
User segmentation is limited to 10 segments and creating new segments takes a day. Any funnel calculations take a day. Certain steps can't have conditions applied to them.
Con Real-time data is not instant
Unlike many competing products, Flurry updates data every few minutes instead of every few seconds.
Splunk is pretty expensive compared to other solutions.
The interface and service are very antiquated
Con Seriously SLOW ingest
Their docs and sales say it will ingest up to 20k EPS, but reality is more like 1k eps per server.
