node-exporter doesn't export node_memory_MemAvailable_bytes metric

I have installed latest node-exporter on machine with Linux Mint 17 (kernel 3.13). There is just one problem - I don't get node_memory_MemAvailable_bytes metric. I tried sysctl kernel.perf_event_paranoid=-1, but this doesn't help. Other memory metrics like node_memory_MemTotal_bytes are being shown.

What may be the reason and how to export available memory?

    Blockquote Kernel 3.13 doesn't expose MemAvailable information in /proc/meminfo as it was introduced in 3.14. That's why you cannot see it in node_exporter.
