Wow. Two degreed engineers talking. What are the chances?

I was actually thinking more like... "This is what your SAR data looks like - loads of numbers you don't understand. No, please don't be scared, here let me make a pretty coloured graph for you. Look, you see that bit right there... that's you running out of memory. That dip there.. that's what happens when you get Out of Memory and I reboot your machine - yes you're right, you probably could use more memory, let me get someone to quote you on that" > But that aside, being that you are at a hosting company, you do use mtrr > for your own monitoring, correct? ;) Our bandwidth graphs in the customer portal I think use mtrr, I wouldn't know about monitoring graphs - we don't offer that in my division. There's about 2500 employees and I'm not the one in charge of monitoring anyway ;o) -- Sam _______________________________________________ rhelv5-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv5-list
