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: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for implementing a health monitoring system for a cloud application platform. One of the methods includes deploying, by a health monitoring application of a cloud application platform that provisions resources from an underlying cloud infrastructure system, probes for testing components of the cloud application platform. Each probe is configured to perform tests that measure performance of a component of the cloud application platform. A probe can attempt to provision resources from the underlying cloud infrastructure system by launching a test application on the cloud application platform and determine whether the test application launched successfully using resources from the underlying cloud infrastructure system.
