clip_image002When analyzing a (performance) issue in Fusion Middleware components, Dynamic Monitoring Service (DMS) Metrics can support you with the necessary information to support resolving the issue. DMS Metrics can be accessed using a variety of tools like JConsole, Oracle EM, WLDF, WLST and the DMS Spy servlet. The DMS Spy servlet is a perfect tool to get insight in the actual metrics but does not provide a way to store or graph these metrics over time. In Oracle EM Fusion Middleware Control you can view graphs of some metrics over time, but it is not possible to store these for review. To quickly get the needed graphs i wrote a WLST script that recorded the selected metrics to a csv which i could upload to plot.ly to generate graphs in minutes.

To record the DMS metrics to a csv file execute the script with the required arguments as shown in the example below. For more information on the argument metrictables follow this link; metrictables. Make sure to enclose the metrictables argument in single quotes, even if you only need one metric table. e.g. ‘”OIM_*”‘. Read the complete article here.
