What are high buffers / what does this mean exactly?

I see this come show up time and again. I work as an infrastructure monitor for my company. I know how to show to the buffers and see what is missing but it doesn't make a ton of sense to me what is going on. Here is a snippet of what I have seen before:
Header pools:
Header buffers, 0 bytes (total 5000, permanent 5000):
5000 in free list (100 min, 10000 max allowed)
312992 hits, 0 misses, 0 trims, 0 created
0 failures (0 no memory)
0 max cache size, 0 in cache
0 hits in cache, 312992 misses in cache
Huge buffers, 18024 bytes (total 1, permanent 0, peak 3 @ 7w0d):
1 in free list (0 min, 0 max allowed)
5724 hits, 5725 misses, 282079 trims, 282080 created



Anybody mind explaining to me what is going on here? I'd like to get a firm idea of what these buffer counters mean.
