Now Cisco have given up on the whole small cells idea. And a lot of it is because of their botched management practices and some of it is also due to Ubiquisys' own inefficiencies.
I have many complaints: Flash UI, data is rolled up almost immediately, use of averages, lots of capability is provided by ancient and unmaintained third party plugins. They have weird notions of compatibility (agent has to be same major version as controller) which leads to heartache when they don't migrate your SaaS controller when they said they would. Worst of all is several times the Java agent itself has been the source of a memory leak. I would expect more based on the price.
More recently, they have started trying to be all things to all people instead of being a fair-to-middling APM. Make it so I don't throw up in my mouth every time I use the UI and then we can talk.
Disclaimer: I work at a startup that is in the same space as AppDynamics
AppDynamics would have been one of the first SV IPO in 2017. How many SV tech IPOs will we actually see in 2017?
