-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I am running FreeBSD 4.11 it is a PIII 800 My system is running MRTG and SNMP for monotoring network switches. The system is very sluggish and sometimes not responsive. MRTG has had problems with writing the new logs. I am having trouble understanding how load averages work. On some sites they say a load average of 3 is high and to put services on another server others say if it is over 1 put move services to another server. I have read the handbook http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/basics-processes.html I guess I am not getting it can someone help me how are load averages figured out and what do they mean? What is a high load average? Here is the load on my system #w load averages: 1.52, 1.11, 1.04 #systat ~ /0 /1 /2 /3 /4 /5 /6 /7 /8 /9 /10 ~ Load Average |||||||| ~ /0 /10 /20 /30 /40 /50 /60 /70 /80 /90 /100 ~ <idle> XXXXXXXXXXX root perl XXXXXXXXX root perl XXXXXXX # swapinfo Device 1K-blocks Used Avail Capacity Type /dev/ad0s1b 525120 272 524848 0% Interleaved -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (MingW32) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFCb9JuU1XvdHZC/KcRAhzEAKCKpQnz+hCR6qEVgeJz+j58DG5KtwCfRQhh WhErjYIBjc4vuEiej3TyWlM= =gMiZ -----END PGP SIGNATURE-----
