Abstract: By monitoring requests to and from components of an application, an application analysis engine generates an inter-component graph for an application that identifies how the various components in the application are connected. When a performance issue is detected in association with the application, a traversal module traverses the inter-component graph to determine the possible execution paths that may have been the cause of the detected issue. The traversal module transmits requests to the correlation module to compare the metrics time series of the different components in the execution path with the detected issue. The correlation module compares metrics time series with the issue metric to identify correlations between execution patterns. The results of the correlation may be presented in a report that visually identify the root cause of the detected issues.

Abstract: A common vendor application that can be called from multiple vendor applications is loaded onto a communication device. When the common vendor application is called from an application provided by a vendor, the common vendor application sends a request to access vendor configuration information to a common vendor server. The request includes a vendor identifier that uniquely identifies the vendor. In response to receiving the request to access the vendor configuration information, the common vendor server identifies vendor configuration information for the vendor. The vendor configuration information is sent the common vendor application on the communication device. The common vendor application uses the vendor configuration information to customize the common vendor application specific to the vendor. This allows multiple vendors to use the same common vendor application, but to have a common look-and-feel. It also reduces the number of applications necessary to support multiple vendors.
