Traffic Manager logs activity (hits per minute and data transferred) for Virtual Servers, Pools and Nodes. You can view the logged data on the Activity -> Historical Activity page in the Admin interface. However, sometimes it is usefule to extract these graphs and archive them. The Admin server doesn't provide a facility to this, so this article presents a simple perl script that generates these graphs.
Using the Script
Download the script attached to this article and copy it on to one of your Traffic Managers (it must be run from a Traffic Manager host or virtual appliance). Ensure that the script is executable.
Running it with no arguments will produce the help output:
Usage: ./getHistoricalActivity.pl --output=image.png [OPTIONS]
Generates a graph of historical activity. If given no
arguments, will default to graphing all virtual servers for 24 hours
Required arguments:
--output=FILE File to output image to ('-' for stdout)
Optional arguments:
--time=HOURS Number of hours to graph (default 24)
--width=WIDTH Width of output graph (default 640)
--height=HEIGHT Height of output graph (default 480)
--allvs Graph all Virtual Servers (default)
--allpools Graph all pools
--allnodes Graph all nodes
--vs=VS1,VS2 Graph a subset of virtual servers
--pool=POOL1,POOL2 Graph a subset of pools
--node=NODE1,NODE2 Graph a subset of nodes
--linear Graph using a linear axis (default)
--logarithmic Graph using a logarithmic axis
--hits Graph hits per minute (default)
--bytes Graph bytes per second
--help Show this help message
Running it just the --output argument will generate an image like the following:
The line colours and the virtual server names are output to STDOUT:
# ./foo.pl --output=foo.png Line colours: 00cfff: apache ffe626: Zeus AFM Integration 9a41d8: Web Site 00d840: SSL Passthrough ff4ca8: soundex
