If you run a lot of workflows and have noticed that you are not seeing some of the workflows in the Workflow Run window, this post may help.
Your workflows might be running, but you are not seeing some of them because you have exceeded the maximum number of workflow runs that will be stored in each of the folders.
In Informatica Workflow Monitor, change the “Maximum workflow runs per folder” property. From Informatica Workflow Monitor, select the Tools -> Options menu item.

Then, change the “Maximum workflow runs per folder” to a number that is higher than the highest number of workflows that are run in your cycle for a given folder.

Save changes. You will now see more workflows in the output after your next job cycle.
