The storage allocation system reduces the amount of storage needed to store data, and also to store the most interesting dynamic data samples (e.g., waveforms). Dynamic data is relevant if it has changed from a previous sample. Changes need to be detected for different machinery conditions. The storage allocation approach normalizes static data to a percentage of danger alarm value that indicates how much the data is changing. The difference of successive percent of danger alarm values provides an instantaneous change value indicating how interesting the data is. To manage how much data is collected; the system maintains an interestingness threshold and stores data samples having an interestingness value above the threshold. The threshold is automatically adjusted if too much/little data is being saved. This approach optimizes the amount and value of data stored and data storage requirements for improved data storage efficiency.
A computer-implemented method for controlling the saving of data within a computer system including a client computer, a server, a data storage medium which are connected via a communication network, and a computing arrangement of at least one of the client computer and the server, the computing arrangement having a data historian and a dynamic data storage allocation module, the method, comprising:
A storage allocation system configured to efficiently store data in a data storage medium within a computer system, the system comprising a computing apparatus of at least one of a client computer and a server, the computing arrangement having a data historian and a dynamic data storage allocation module, the data historian configured to access data samples from a machine data source, each accessed data sample having a respective percentage of danger value, the dynamic data storage allocation module configured to determine an interestingness value for the accessed data samples in accordance with the percentage of danger values, the dynamic data storage allocation module further configured to determine whether the interestingness value for the accessed data samples exceeds an interestingness threshold, the computing arrangement configured to collect and store collected data samples that exceed the interestingness threshold in the data storage medium, and the dynamic data storage allocation module also configured to modify the interestingness threshold based on the saving of the collected data samples.
