What do you like best?
The .NET and Java agents hide incredible amounts of additional monitoring capabilities not enabled by default. Given a fair level of autonomy a senior administrator would help any company realize an unparalleled level of visibility and reactivity.
The Server Visibility is just what an Ops team needs. Clean, effective, data-center-wide visibility on CPU, RAM, DISK, and NETWORK. All cleanly cut up into individual tabs.
Appdynamics is constantly improving,
You can work on a hybrid solution leaving the gathering of critical intel to occur within your own server hardware and the resource heavy EUM to occur on AppD hardware over a secure connection.
Having more visibility faster than even our data center hosts have it.
The entire 24x7 support staff knows their craft and are effective at resolution response.
The new logo looks great, this is important when you put your tool belt utility labels on your public site.
AppDynamics is highly configurable for "actions" which include alerts and actions.
What do you dislike?
There is no direct dial for support. I've been stuck playing email tag to get to a GTM going during a critical outage. Support is usually very responsive, but with all the alarms and whistles during mission critical outage I want clear connectivity to support, and a direct link to a GTM 5 minutes ago.
The database tools are a bit lacking in the 4.3 version and don't seem to have been improved that much leading into 4.4. You still get a really good level of "add-on" visibility to a tool such as Redgate. However, I wouldn't consider this a "one stop platform shop" until the database visibility improves greatly.
Large companies need to realize that the administration of AppDynamics is at least 1 full time job.
Some of the ability to configure when paired with a large environment can cause you the need to revert changes and re-configure to avoid confusion.
Recommendations to others considering the product:
Do not think that this application will solve your problems if you are not willing to invest the appropriate time and resources into it. Invest in training a local asset and have them work with the services group to properly implement. Appdynamics is well worth the money for the software if you have the money to support it internally as well. Almost all installations > 20 agents take a full time asset with Admin privileges in your environments.
Expect great things from this company in the near and distant future.
What problems are you solving with the product? What benefits have you realized?
We have realized far greater visibility and mobility as an Operations team. We have been able to double our product footprint without increasing our staff and without overloading them either. Lastly, we were able to boost the "signal to noise" ratio on our alerting strategies and script out automated responses during out of office hours.
