Provided are methods and computer program products for monitoring the performance of network applications executing within operating-system-level virtualization containers. Methods may include enumerating operating-system-level virtualization containers on a networked device; creating a named pipe accessible by at least one application running in each operating-system-level virtualization container; retrieving, via the named pipe, performance data gathered by the at least one application, including an identification of each operating-system-level virtualization container; generating metrics based on the retrieved performance data; and generating an event incorporating the metrics, including operating-system-level virtualization container identifiers.
