I keep noticing that there’s a big disconnect between how I treat things at work and how I treat things on my own server. I suppose part of it’s that I spend 8 hours a day working on the site at work, whereas I only have spare time here and there on the weekends to work on my own site’s infrastructure. As a more concrete example, we have lots and lots of monitoring of all our servers at work. (We’d be crazy not to?)

I haven’t done so much here, because everything works fine, and I’ve put my time into other things. But I just decided to work on getting some better graphs going with Cacti. And I noticed something quite telling when I started graphing Memcache usage.

I’m currently using 35kB of storage in Memcache. I use it quite lightly, just caching a few page elements. I’d be better off using APC to store these, I think, but built it to use Memcache a long time ago. So, with 35 kB of data being stored in Memcache, how much memory have I allocated to Memcache?

64MB.

I think I’m going to adjust things a little bit now that I’ve noticed this…
