A script is needed to load the NODESPECS table. This table is defined to store the specifications for the target nodes and any calculated optimal window size and number of streams for iperf or thrulay probes. The window size is calculated and stored in the table daily by 'find-winsize'. No script have been written to calculate the optimal number of streams to be used, but there is a field in the table for it. Currently for multistream iperf and thrulay probes, the window size and number of streams should be included in the 'toolopts1' field of the TOOLSPECS table.
Upgrade to find-winsize
'find-winsize' reads the NODESPECS table for each node and calculates the optimal window size for single stream 'iperf' and 'thrulay' probe. This should be extended to handle multi-stream probes also. Currently multi-stream probes are hard coded the the specific TOOLSPECS table entry for multi-stream iperf and thrulay ('tlaytcp') probes. If this script is modified, note that one will have to modify the database entry and the code that does the probes.
