Subject: [pve-devel] [PATCH v2 qemu-server 1/2] fix #6207: vm status: return undef values when disk{read, write} cannot be queried
Date: Thu, 25 Sep 2025 14:25:08 +0200	[thread overview]
Message-ID: <20250925122829.70121-2-f.ebner@proxmox.com> (raw)
In-Reply-To: <20250925122829.70121-1-f.ebner@proxmox.com>

If disk read/write cannot be queried because of QMP timeout, they
should not be reported as 0, because a consumer of the RRD stats
cannot distinguish between 0 being an actual 0 value and 0 being an
indicator for the absence of the real value. The RRD graphs in the UI
will already show this correctly.

Signed-off-by: Fiona Ebner <f.ebner@proxmox.com>

Changes in v2:
* New approach, return undef instead of caching previous value.
