Patent ID: 7937466

Claim:
A computer program product, stored on a non-transitory computer medium, for collecting SNMP bandwidth data from a network device via a data collection system, the computer program product including instructions for causing a computer to implement a method, comprising: producing a master text file via a master server and producing a slave text file via at least one slave server, the master and slave text files produced in response to simultaneous collection of data samples from a port on the network device, the data samples collected at predetermined time intervals, and over a predetermined time period that collectively define a data sampling run; and performing data computation activities that include generating a clean data file by filling in data missing in the master text file using data from the slave text file, comprising: sorting data in the master text file and the slave text file by the port; sorting data samples for the port by time of data collection; and for each of the data samples: adding a designated interval of time to a time on the network device resulting in a target network device time, the time on the network device corresponding to a time the data sample was collected; examining data samples in the master text file and the slave text file that correspond to the time the respective data samples was collected; selecting from one of the master text file and the slave text file the data sample with a collection time most closely matching the target network device time; and storing the selected data sample in the clean data file.
