memory - Plugin to monitor memory usage
Warning and critical values can be passed in environment variables as byte values or they can be percentages using a % sign and the value will be calculated dynamically by the plugin. Thus, to warn on swap at 50% the configuration is:
[memory] env.swap_warning 50%
Note that swap is calculated against the total swap amount (SwapTotal), and all other fields are calculated against the total amount of memory (MemTotal).
