Solutions

1. Ensure the system exposes swap memory information readable by the process (check /proc/swaps and /proc/meminfo permissions).
2. If the host has no swap configured, this error is expected; ignore it or disable swap collection.
3. On containers or restricted environments, run with sufficient privileges or mount /proc so gopsutil can read swap stats.

When it happens

Trigger: Occurs when the system cannot read swap memory information from /proc/meminfo or the sysinfo syscall fails, typically on minimal containers or restricted environments.

Common situations: Running inside a container without /proc mounted, on a host with swap disabled reporting inconsistencies, or on an OS where swap metrics are unavailable.
