The Firebox Memory graph in Fireware Web UI and WatchGuard Cloud, does not accurately reflect the total amount of available system memory on the Firebox. As a result it might indicate that a Firebox is low on memory when it is not.
To understand how much available memory your Firebox has, review these memory statistics in the Firebox System Manager Status Report:
To improve system performance, Fireware allocates most available memory to buffers and the cache. If a process requires more memory, Fireware automatically frees up memory used by buffers and cache.
The Memory graph shows the difference between the MemTotal and MemFree statistics. The Memory graph does not reflect the Cached and Buffers memory statistics. Because of this, high memory usage statistics on the Memory graph do not usually indicate a true low memory condition.
