A new transaction set is compared to a plurality of transaction sets represented in a Compressed Frequent Item Set (CFIS), wherein the CFIS maintains a count for each transaction set represented in the CFIS. When the new transaction set matches a transaction set represented in the CFIS, the count for the matching transaction set in the CFIS is incremented. When the new transaction set does not match any transaction sets represented in the CFIS, the new transaction set is added to the CFIS. If there are intersections between two or more events of the new transaction set and the events of the plurality of transaction sets represented in the CFIS, the count for the transaction sets in the CFIS that intersect with two or more of the events of the new transaction set is incremented.

Frequent item set tracking

Methods, devices, and systems for point value change notification are described herein. One system () includes a message broker () to receive data from a data acquisition (DAQ) system, a first building management system (BMS) instance () connected to the message broker () to process a first portion of the DAQ data, a second BMS instance () connected to the message broker () to process a second portion of the DAQ data, and a web application () connected to the message broker () to generate a notification of a change in point value of a portion of the first portion or the second portion of the DAQ data, where the first BMS instance () and the second BMS instance () are provisioned with a plurality of computing resources deployed in a computing environment () and are ultimately executed on hardware.

Point value change notification

Methods and systems for monitoring the performance of a building management system by analyzing log files of various modules of the building management system. A user request is received at a first one of the plurality of modules of the building management system, which initiates a sequence of messages processed by two or more modules. Each of the sequence of messages include a common tag value that corresponds to the user request. Each of the plurality of modules that process one of the sequence of messages logs the corresponding message including the common tag value in a corresponding log entry. The log entries are analyzed to identify resource utilization of at least some of the plurality of modules.
