Re: Memory cache in Linux

You can change this on a per-device, or global basis.

To do it globally, go Resource -> Performance Management -> Global Index settings. Expand Memory Usage, double-click on "Memory Usage", and either disable the Thresholds, or change the values.

To it on a per-device basis, go Performance Management -> Monitoring Settings. Find the device you're interested in. Click on "Modify Index". On the pop-up, find the "Memory Usage" monitor. Uncheck "Global Index Settings", and disable/adjust thresholds as required.

There are also ways to modify this for a group of devices - see this video:
