Linux TOP is a indicator?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I have one of my database server that I run the "top" command:

top - 16:16:30 up 42 days, 13:23,  4 users,  load average: 3.13, 3.52, 3.36
Tasks: 624 total,   1 running, 623 sleeping,   0 stopped,   0 zombie
Cpu(s): 1.4%us, 1.1%sy, 0.0%ni, 84.4%id, 12.9%wa, 0.0%hi, 0.2%si, 0.0%st
Mem:  16432240k total, 16344596k used,    87644k free,    27548k buffers
Swap: 10241428k total,  3680860k used,  6560568k free,  6230376k cached

I´m afraid of two things, one is the "load average", I think 3 is too much, another is the "swap", almost 4GB of swap, I think that is too much swap.

Am I right?

Can I use those indicators to know if my database is ok?

Thanks

Waldomiro
