There are several scripts which need simple modification to adapt them to new features which have been recently added to IEPM-BW.  They are written in perl.

show-probe-commands \[-n aliasname\]

This reads from the mysql data base TOOLSPECS table the components of the commands which are performed by the monitoring. Currently, when called without any arguments, it prints the exact commands executed to do a test. If called with '-n aliasname' it only prints the commands for that aliasname.

Scripts which may be useful in completing these modifications can be found in the Group Table Access Commands  documentation

Geoplot Modifications

Fawad put together a package using GEOPLOT for displaying lines and monitoring hosts and target hosts around the world.

The code can be downloaded from SLACand it is the file geoplot.tar.gz in the code directory. The file update-geoplot.txt is an example of the data file that Geoplot to displays.

Script to Load the NODESPECS Table

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.
