Filtering event log entries

摘要

A method for efficient logging in a control system is provided. A first plurality of registers, frequently accessed registers, is identified. A request is received from a server to access at least one of the first plurality of registers. The request includes a second plurality of registers and a plurality of data values to be stored in the second plurality of registers. At least some registers included in the request are frequently accessed registers. A third plurality of registers is identified based on predetermined criteria for inclusion. The third plurality of registers is a subset of the second plurality of registers storing a corresponding subset of the plurality of data values. A log entry is stored in an event log file corresponding to each data value included the third plurality of registers.

1. A method for efficient logging in a control system, the method comprising:
identifying, by one or more processors, a first plurality of registers based on a frequency of requests to access data values stored in the first plurality of registers; receiving, from a server, a request to access at least one of the first plurality of registers, the request comprising addresses of a second plurality of registers and a plurality of data values to be stored in the second plurality of registers, the addresses of the second plurality of registers having a first register address and a last register address, wherein the first register address points to a first register in the second plurality of registers and wherein the last register address points to a last register in the second plurality of registers; identifying, by one or more processors, a third plurality of registers based at least in part on predetermined criteria for inclusion into the third plurality of registers, wherein the third plurality of registers is a subset of the second plurality of registers having a corresponding subset of the plurality of data values; and storing, in an event log file, a log entry corresponding to each data value in the corresponding subset of the plurality of data values.
