Hi   This can happen due to a variety of reasons   Out of the Box, AppDynamics will have limits set to ensure it does not do excessive snapshots, as this adds overhead to the application.   Most of the time you will not have a 1 to 1 ratio between Errors and snapshots, especially when the error rate is very high.   You will have to check what limits you have set, under Slow/Error Thresholds for the application, and there are options to increase the snapshot collection to be more aggressive, however it will add additional overhead to the system.   You need to finely balance the overhead AppDynamics puts on the application to how many snapshots it collects when errors occur or slow transactions happen.   In summary AppDynamics will monitor and report on every error, but not take a snapshot for every error(on low error rates it will mostly take a snapshot for every error).   You can then use the Exceptions & Error screens to zone in on the errors being seen. You can also use the Dashboarding side to report on types of errors etc.   Hope this clears things up     ... View more

Hi   As per the documentation, you can only access the last 1440 minutes of data.   The start and end dates cannot be used when using accessing the data via that API call from what I know, if on LITE version.   On a side note, if you use developer options in your browser, in the UI by setting start & end date e.g in metric browser, it should possibly give you a working query you can maybe use if you really need to use start and end dates.   As you only have access to the last 1440 minutes, is there a reason you are trying to use start & end dates? ...

Hi   Yes mean your EC2 instance:)   I have just quickly gone through the AWS docs, and resource-id doesn't look like an actual tag, you use the resource-id to set the tags.   Best would be to log a call to AppD to ask how they are getting that value, as they state so in their docs, otherwise there must be a way to dynamically set the tag by querying the resource id when you create an EC2 instance   Ciao ...
