Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media for a platform orchestrator to use verified add-on resources. One of the methods includes receiving, by a platform orchestrator, an add-on resource API command that references an add-on resource installed on one or more software platforms launched by the platform orchestrator. A request to execute the add-on resource API command is provided to a platform controller of a software platform of the one or more software platforms launched by the platform orchestrator. The add-on resource API command is executed including identifying one or more instances of the add-on resource referenced by the add-on resource API command that are executed as workloads on the software platform launched by the platform orchestrator.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generating user interfaces and alerts for applications running on software platforms using indicator files. A method includes obtaining, by a software platform system configured to host computing tasks in a cloud computing environment of the distributed computing system, a user-customizable indicator file that specifies a set of indicators and, for at least one of the indicators, one or more alert thresholds. Each indicator is a measurable parameter for a particular computing task hosted by the software platform system. A monitoring service uses the user-customizable indicator file to obtain one or more values for each of one or more of the indicators from the software platform system. The monitoring service uses the user-customizable indicator file to generate a graphical user interface that includes, for each indicator, data specifying the one or more values for the indicator.

Abstract: Logs emitted in a cloud application platform can be cached. Log events emitted by one or more log emitters in the cloud application platform are received. Cache-allocation data that specifies, for each log emitter, a quota for storing log-event data for the log emitter is maintained. For each log emitter of a plurality of log emitters in the cloud application platform, a respective local cache of log events in computer memory is maintained. A global cache for all of the plurality of log emitters in the system is maintained. Each node in the global cache represents a different respective local cache.
