I have 2 server . I use FreeBSD6.1 and Freebsd6.0 on them.
1 - Is there any program or command about how much the server use the parameters sysctl values and whether the server exceed the sysctl limits or not ?
can you say a command or tool except top, ps, netstat -m ?
2 - While I am looking at system performance with systat command, I sometimes see values in usage of disk over %100 as below,
Disks amrd0 pass0 54 ofod intrn 2002 cpu1: time
KB/t 16.00 0.00 88 %slo-z 114464 buf 2002 cpu3: time
tps 251 0 531 tfree 274 dirtybuf
MB/s 3.93 0.00 100000 desiredvnodes
% busy 102 0 83032 numvnodes
What cause does this condition ?
3 - On FreeBSD6.1 when I typed "netstat -m" I saw below values;
173/2827/3000 mbufs in use (current/cache/total)
164/1910/2074/17088 mbuf clusters in use (current/cache/total/max)
164/479 mbuf+clusters out of packet secondary zone in use (current/cache)
0/0/0/0 4k (page size) jumbo clusters in use (current/cache/total/max)
0/0/0/0 9k jumbo clusters in use (current/cache/total/max)
0/0/0/0 16k jumbo clusters in use (current/cache/total/max)
371K/4526K/4898K bytes allocated to network (current/cache/total)
105906/27714/27042 requests for mbufs denied (mbufs/clusters/mbuf+clusters)
0/0/0 requests for jumbo clusters denied (4k/9k/16k)
0/9/4528 sfbufs in use (current/peak/max)
0 requests for sfbufs denied
0 requests for sfbufs delayed
4 requests for I/O initiated by sendfile
109 calls to protocol drain routines
What does "105906/27714/27042 requests for mbufs denied (mbufs/clusters/mbuf+clusters)" mean ?
