I have a Cent OS 6.4 Apache Nginx VPS. I have WHM cpanel. How do I check past 24 hours or 48 hours this server RAM usage?
I use new relic server monitor web application. It reported that, this VPS peak time RAM usage less than 30%. Also WHM service status shows similar figures. But when I'm contacting my VPS company, they mentioned that, it uses more than 95% RAM (peak time). I'm totally new to the server management.
When I run
free -m command, I receive following output. But at the same time WHM cPanel service status shows, Memory Used 16.88% (442,464 of 2,621,440). Also new relic shows similar statistics (Similar to the WHM).
