Observer Infrastructure stores its trending and polling data on the hard drive in the
C:\Program Files\ObserverInfrastructure\Logs directory. A separate directory is created for each device group and route. Inside of each of those directories is where all of the data is kept. With autopolling enabled it is possible that a lot of data could be collected. If you find that too much data is being stored, you can configure how much data to keep. Another option may be to reduce the polling interval. See “Using the Polling feature” for details.
