As Rich says, there doesn't seem to be anything wrong with your storage use. In addition to the 278MB being used for cache, there is 127MB being used for buffers, for a total of 405MB that can be freed for application use, if needed. If you look, there is ** 0K ** swap being used. Your system is not storage constrained at all, at this point.
The fact that your vendor's "tech" doesn't understand this leads me to believe you are not working with an organization that is Linux savvy at all. You might want to keep that in mind as you go forward.

I got a call today from one of their techs who is concerned that "top" is reporting memory usage of 625,664k, with only 5,204k free. There being a demo on Tuesday, she is worried that something is eating up the memory. As a complete novice at both Linux and VM, I'm not sure how to find out what's going on or if there is even anything to worry about. According to the tech, mysqld should only be using about 4%-5% of the memory on the system, but when I check it using "top" I see 14 separate mysql user instances, each with a size of 28,712. Does this jibe with the observations of anyone else out there using MySQL? I know that using "top" in a VM environment is not a particularly good way to go and the CPU usage reported can be misleading, but I don't know if there are similar issues with memory usage. Any suggestions as to what to look for?
