According to some embodiments, an application deployment data store may contain electronic record associated with an application package uploaded by a deployer. An artifact report platform may access the application deployment data store and, based on the information in the application deployment data store, perform the following for each resource associated with a scope of a cloud-based or on-premises environment/system infrastructure: create a root artifact of a tree; detect the root artifact's set of artifacts; build an artifact dependency tree; for droplet roots, match sub-resources of droplet resource roots; and write the root artifact recursively to a result stream. Based on the result streams, the artifact report platform may output the artifact report to the remote operator device via the output port.

Embodiments facilitate the efficient handling of service requests by a Platform-as-a-Service (PaaS) infrastructure. The platform may comprise a central controller communicating with a plurality of execution agents on one or more hosts. The central controller may parse client requests manipulating application state (e.g., scale, start, stop app, clear) into a sequence of fine-grained instance requests (e.g., start, stop, stop all, clear) that are distributed to the application program interfaces (API) of execution agents on the platform. The central controller may assign a priority to the fine-grained requests. The priority may take into consideration one or more factors including but not limited to: request creator (user, system); operation type (start, stop, stop all, clear); instance number; sequence number of the fine grained request within the original received request; hierarchy level (organization, space); and application. Fine-grained requests may be distributed by a scheduler to a queue of the execution agent.

Scheduling of micro-service instances

The present disclosure involves systems, software, and computer implemented methods for remotely debugging applications in a private cloud environment. One example method includes establishing a first secure connection with a client device in response to receiving a request from the client device for a secure debugging session to remotely debug an application instance running in a private cloud environment. A host that is hosting the application instance is identified. A second secure connection is established with the identified host. A request is submitted, over the second secured connection, to the identified host, to instantiate a debug proxy process. The debug proxy process is configured to establish a secure inter-process communication channel with the application instance and instruct the application instance to run in a debug mode.

Debugging in a private cloud environment

The present disclosure involves systems, software, and computer implemented methods for monitoring processes running on a platform as a service architecture. One example method includes storing a received sample of monitored attributes of a computer process in a sample memory buffer that includes other stored samples. A determination is made that the sample memory buffer is full. The sample memory buffer is compressed. A starting position in a compressed sample file store at which to store the compressed sample memory buffer is determined. The compressed sample memory buffer is stored at the determined starting position in the compressed sample file store. The starting position of the stored compressed sample memory buffer is stored at a particular location in a file position index. A collection timestamp for the sample in a timestamp index is stored at a timestamp index location that matches the particular location in the file position index.

A thread dump viewer presents information for a plurality of threads. The information about the threads can be presented in a table view. The thread dump viewer can allow the user to expand a thread in the table view to see a stack trace for the thread. The stack trace may include information for objects that are associated with other threads. For example, the thread may be waiting on a lock object locked by another thread. The thread dump viewer can present information about the associated thread based on a user interaction. This process can be continued iteratively, allowing the stack traces of interrelated threads to be seen to arbitrary depths.

A method for profiling an application on a virtual machine is provided. A series of analysis steps to be performed on profiled data can be created. The series of analysis steps can be saved as a report specification. A back-end profiler can then be caused to perform profiling on the application. Profiled data can be received from the back-end profiler. The profiled data can be stored as a model. The model can then be adapted based on the series of analysis steps from the report specification. Output data can be generated based on the adapted model. Finally, the output data is displayed to a user.

Automatic profiling report generation

Systems and methods are provided to automatically analyze performance of an automatic memory management system. One example embodiment involves automatically gathering, using at least one processor of the server, garbage collection information associated with the garbage collection process and storing the garbage collection information in a garbage collection output file of a file system. The garbage collection output file may be analyzed to identify a plurality of flags associated with a performance of the server system that does not meet one or more performance thresholds. In certain embodiments, a first flag of the plurality of flags is associated with a first portion of the garbage collection information, and a second flag of the plurality of flags is associated with a second portion of the garbage collection information that is different from the first portion of the garbage collection information.

Automatic analysis of issues concerning automatic memory management

In an example embodiment, a communication is received from a software tool. The communication may be intended for a virtual machine and may contain an identification of a virtual file. A virtual file can then be retrieved using the identification. The virtual file defines a file socket, the file socket providing a communications channel for stream-based communications. Then the file socket can be established as a communications channel between the software tool and the virtual machine based on the virtual file.

Communication infrastructure for virtual machines

A thread dump analysis tool analyzes a series of thread dumps and identifies one or more potential problems in the application from which the thread dumps were generated. Hints regarding the potential problems are presented. The hints can be generated based on relative values generated by analysis of sequential dumps. The hints may be hints that could not be generated by analysis of a single thread dump. Other hints may be hints that are enhanced by analysis of multiple thread dumps, whose importance is made clearer by appearance in multiple thread dumps, or that are unchanged in detection, importance, or both, by the use of multiple thread dumps. The hints can then be presented in order of importance. Additionally or alternatively, hints below a certain threshold of importance can be hidden.

System diagnostics with thread dump analysis

The present disclosure describes methods, systems, and computer program products for providing remote debugging of a cloud application across a wide area network. A method includes transmitting, from a remote communication device to a cloud computing device, instructions to adjust a running application to a debugging mode; receiving, at the remote communication device from a server coupled to the cloud, aggregated thread data in a data packet by using a second debugging data protocol different from the Java Debug Wire Protocol; receiving a debugging command and applying the debugging command to the cloud application running in the debugging mode.

Debugging applications in the cloud

The present disclosure describes methods, systems, and computer program products for providing remote debugging of a software or cloud application across a wide area network. A method includes transmitting, from a remote communication device to a client or cloud computing device, instructions to adjust a running application to a debugging mode; receiving, at the remote communication device from a server, aggregated thread data in a data packet by using a second debugging data protocol different from the Java Debug Wire Protocol; receiving a debugging command and applying the debugging command to the application running in the debugging mode.
