getting memory info: %v

Error message

getting memory info: %v

What it means

Non-fatal: mem.VirtualMemory() failed, so TotalMB/UsedMB/UsedPercent stay unset and the memory section of server-stats shows as unavailable; recorded via addErr and collection continues (swap is attempted separately).

Solutions

1. Confirm /proc/meminfo is mounted and readable from the Glance process
2. Adjust container security options (seccomp/apparmor) or mounts that block /proc
3. If memory stats are simply unavailable in the environment, suppress the memory panel rather than chasing the error

Example fix

# docker run
# before
docker run -v ./glance.yml:/app/config/glance.yml glance

# after (ensure proc is available)
docker run -v ./glance.yml:/app/config/glance.yml --pid=host glance

func isMemoryErr(err error) bool {
	return err != nil && strings.Contains(err.Error(), "getting memory info")
}

info, err := sysinfo.Get()
if isMemoryErr(err) {
    // hide the memory panel; other stats remain valid
    renderServerStats(info, hideMemory=true)
}

When it happens

Trigger: Reading memory stats fails: /proc/meminfo missing or unreadable on Linux, hoststats API denied on macOS, or WMI/perf-counter failure on Windows.

Common situations: Containers with /proc masked or not mounted; minimal base images; systems where the gopsutil backend syscall is denied by seccomp.
