X-BeenThere: pve-user@lists.proxmox.com X-Mailman-Version: 2.1.29 Precedence: list List-Id: Proxmox VE user list List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 18 Aug 2020 20:39:11 -0000 Dear all. the memory usage bar in the VM summaires in PVE (6.1-3) shows "active" memory including caches, which is in practice misleading. E.g. this system $ free -m total used free shared buff/cache available Mem: 7821 4778 177 51 2864 2738 Swap: 3276 123 3153 $ is shown as using 7.46 GB memory, in red warning color, since this number exceeds 90% of the available 8 GB. However IMHO the almost 3 GB memory used as buffer/cache are irrelevant as they will be freed as soon as they are required by applications. Hence I'd rather see the bar showing me only 4.8 GB of used memory. Is that achievable? The guest OS is CentOS 7.x. The qemu gest agent is installed. Cheers, Frank
