In some embodiments, the service monitor stores a log relating to the use of the service each time the application uses the service. The application performance tool also includes an error monitor to detect an application error and report the application error to a performance monitoring server along with one or more logs relating to the use of the service when the error is detected. The performance monitoring server then provides an error report with the one or more logs to assist a developer in diagnosing the cause of the error with the application.

Some embodiments provide a method and system for automatedly scheduling virtual machines across several hosting servers of a hosting service provider. Some embodiments perform the automated scheduling by receiving a server configuration that includes constraint data. In some embodiments, the constraint data includes a specified amount of hosting resources needed to implement the server configuration. Based on the constraint data, a scheduling module in the hosting environment determines an optimal distribution of the server configuration across a set of hosting resources that implement the server configuration based on the constraint data. To determine the optimal distribution, some embodiments compute a set of scores for quantifying the specified set of hosting resources required for hosting the server configuration. From the optimal distribution, some embodiments perform a mapping of the server configuration to a particular set of hosting resources of several hosting resources using the computed set of scores.

A system receives ETL specification for processing stream data, including a transform operation represented using a database query specification. The system generates a dataflow graph of a sequence of database queries by decomposing the database query into a first database query that generates an intermediate results table, and a second database query that receives as input the intermediate results table and outputs data used for performing the transform operation. The system executes the sequence of database queries for performing the transform operation on stream data received from the source. When receiving an incremental data set, the system determines an output change set based on the received incremental data set by traversing an execution plan and processing each operator in the execution plan, and computing a change set of a particular operator from the change sets output by the one or more other operators based on the incremental data set.
