Hi,<br>
<br>
I have one of my database server that I run the "top" command:<br>
<br>
<font face="Courier New, Courier, monospace">top - 16:16:30 up 42 days,
13:23,&nbsp; 4 users,&nbsp; load average: 3.13, 3.52, 3.36<br>
Tasks: 624 total,&nbsp;&nbsp; 1 running, 623 sleeping,&nbsp;&nbsp; 0 stopped,&nbsp;&nbsp; 0 zombie<br>
Cpu(s):&nbsp; 1.4%us,&nbsp; 1.1%sy,&nbsp; 0.0%ni, 84.4%id, 12.9%wa,&nbsp; 0.0%hi,&nbsp; 0.2%si,&nbsp;
0.0%st<br>
Mem:&nbsp; 16432240k total, 16344596k used,&nbsp;&nbsp;&nbsp; 87644k free,&nbsp;&nbsp;&nbsp; 27548k buffers<br>
Swap: 10241428k total,&nbsp; 3680860k used,&nbsp; 6560568k free,&nbsp; 6230376k cached<br>
<br>
</font>I&acute;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.<br>
<br>
Am I right?<br>
<br>
Can I use those indicators to know if my database is ok?<br>
<br>
Thanks<br>
<br>
