Abstract: According to one aspect, a method includes: receiving, by a node of a computer cluster, a command for a health status report, the node having a plurality applications and being one of a plurality of nodes of the cluster, the command indicating a class of a health checks to be executed and a scope; identifying, from a configuration, one or more health checks to be executed based on the indicated class; executing the one or more health checks on one or more of the applications and on one or more of the nodes of the cluster according to the indicated scope, where different ones of the health checks are configured to determine state of different ones of the applications; aggregating, by the node, results of the executed health checks; and outputting the aggregated results.

Abstract: In one aspect, a computer-implemented method includes: identifying a plurality of storage devices accessible to a node of a computer cluster, the storage devices being identified as not having labels; determining one or more attributes of individual ones of the storage devices; determining, by the node, intended uses of the storage devices based on comparing the determined attributes to attributes defined within a configuration file; and generating labels for the storage devices based in least in part on the determined intended uses; and applying the labels to the storage devices.
