Pulse was generating tag colours from a hash of the tag name instead
of using the colours configured in Proxmox. Now polls /cluster/options
once per PVE instance and merges the tag-style colour map into state,
which the frontend uses as the first-priority colour source for tag
badges. Falls back to the existing special-tag and hash-based colours
when Proxmox hasn't set a custom colour for a tag.
Proxmox status.Mem includes page cache as "used" memory, inflating
reported VM usage. The existing fallbacks (balloon meminfo, RRD, linked
host agent) were frequently unavailable, causing most VMs to fall
through to the inflated status-mem source.
Adds a new last-resort fallback that reads /proc/meminfo via the QEMU
guest agent file-read endpoint to get accurate MemAvailable. Results
are cached (60s positive, 5min negative backoff for unsupported VMs).
Also fixes: RRD memavailable fallback missing from traditional polling
path, cache key collisions in multi-PVE setups, FreeMem underflow
guard inconsistency, and integer overflow in kB-to-bytes conversion.
The --disk-exclude agent flag only filtered local metric collection but
had no effect on server-side Proxmox disk health and SSD wearout alerts,
which poll the Proxmox API directly. Users excluding disks (e.g.
--disk-exclude sda) still received alerts for those disks.
Agent now sends its DiskExclude patterns in each report. The server
stores them on the Host model and consults them during Proxmox disk
polling — excluded disks get a synthetic healthy status passed to
CheckDiskHealth so any existing alerts clear immediately.
Also adds FreeBSD pseudo-filesystem types (fdescfs, devfs, linprocfs,
linsysfs) to the virtual FS filter and /var/run/ to special mount
prefixes, fixing false disk-full alerts on FreeBSD for fdescfs mounts.
