Description

The 'balb' package provides support for an assortment of common application-level services (e.g., command-line processing). In particular, 'balb' includes the following:

• A mechanism for monitoring and reporting the observable performance of a process.
• Classes for (1) defining commands (as short strings), (2) passing these commands through a pipe-channel to a running process, and (3) registering callback functions to be invoked upon reception of such commands.
• A multi-process performance reporting mechanism and a value-semantic type to represent metrics. Note that the entire {'balm'} package is dedicated to metrics gathering.
• A mechanism that allows clients to monitor whether a resource is being consumed at a particular rate.
• A mechanism that enables clients to monitor and control the use of a resource such that the peak consumption rate and the sustained consumption rate do not exceed their respective configured limits.
• Generic proctor to automatically reserve and release units from a rate controlling object.
