Package Exports
- vmstat-s
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (vmstat-s) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Command-line Example
API Example
In addition to vmstat-s shell command-line, you can also require('vmstat-s') from your node.js application as you wish.
var promise = require('vmstat-s')(); // this return a promise of vmstats instance
promise.then(function (vmstats) {
console.dir(vmstats.getLastData()); // print out initial (mem usage data only)
setTimeout(heartbeat, 2*1000); // interval 2 seconds
function heartbeat() {
setTimeout(heartbeat, 2*1000);
vmstats.next()
.then(console.dir); // print out current data (mem usage data and cpu usage data). Cpu usage is calculated from tick count diffs, thus require at least 2 measures.
}
