> In the reported heartbeat information, the unit of the memory data is bytes,
> which is converted by the formatBytes() function in the utils.js file before
> being displayed in the interface. The cardinality of the unit conversion in
> the formatBytes function is 1000, which should be 1024.
> function formatBytes(bytes, type)
> { if (type !== 'display') return bytes; if (bytes == 0) return '0.0 B';
> var k = 1000; var dm = 1; var sizes = ['B', 'KB', 'MB', 'GB', 'TB',
> 'PB', 'EB', 'ZB', 'YB']; var i = Math.floor(Math.log(bytes) /
> Math.log(k)); return parseFloat((bytes / Math.pow(k, i)).toFixed(dm)) + ' ' +
> sizes[i]; }
