How to reduce the disk space consumed by network trending files
The size of your most recent network trending file increases whenever network traffic is seen. However, the file size is strongly affected by the volume of traffic (number of network connections), the network trending types you choose to track, and certain options within network trending settings. You can best reduce the disk space consumed by network trending files by limiting what you track.
Each network trending file is a summary of one day’s traffic as tracked by the Network Trending tool. In this way, the more network trending files you are able to retain in your storage directory—without sacrificing all of your available disk space to do so—the more days of historical data can be transferred to Apex or viewed using Apex Lite.
Unless you want to rely on scheduled deletions of trending data as your only disk space strategy, you can reduce the overall space consumed by network trending files by limiting what you track. This decreases the size of future network trending files, enabling you to retain more of them and for longer durations before deletions are necessary.
To reduce the disk space consumed by future network trending files, and your most recent in-progress file, perform any or all of the following steps:
Decide if some network trending types are not useful to collect in your network environment, and turn them off.
Set one or several options for Application Performance Analysis that limits tracking to protocols in the protocol list, server connections between defined subnets, or explicitly defined servers only.
 
By following any or all of these steps, you should see a reduction in the disk space consumed by future network trending files.
