sadc is a system data collector - sa1 is a shell script wrapper.
A crontab entry like this:
collects data on the hour and then at 20 & 40 minutes after the hour during business hours 8:00am to 5:00pm
The sa1 output file is stored where your man page says it lives = the file name output by sa1 is usually
sa[nn]
where nn is the day of the month.
Some systems have other implementations of sadc - read your man page.
we have an unix system which has
load average normally about 20.
but while i am running a particular unix batch which performs heavy
operations on filesystem and database average load
reduces to 15.
how can we explain this situation?
while running that batch idle cpu time is about %60-65... (0 Replies)
Hello all, I have a question about load averages.
I've read the man pages for the uptime and w command for two or three different flavors of Unix (Red Hat, Tru64, Solaris). All of them agree that in the output of the 2 aforementioned commands, you are given the load average for the box, but... (3 Replies)
Hello, Here is the output of top command. My understanding here is,
the load average 0.03 in last 1 min, 0.02 is in last 5 min, 0.00 is in last 15 min.
By seeing this load average, When can we say that, the system load averge is too high?
When can we say that, load average is medium/low??... (8 Replies)
Hi,
i have installed solaris 10 on t-5120 sparc enterprise.
I am little surprised to see load average of 2 or around on this OS.
when checked with ps command following process is using highest CPU. looks like it is running for long time and does not want to stop, but I do not know... (5 Replies)
Hello AlL,..
I want from experts to help me as my load average is increased and i dont know where is the problem !!
this is my top result :

Hi ,
I am using 48 CPU sunOS server at my work.
The application has facility to check the current load average before starting a new process to control the load.
Right now it is configured as 48. So it does mean that each CPU can take maximum one proces and no processe is waiting.

lh_node_usage_stats
lh_stats(3) OpenSSL lh_stats(3)NAME
lh_stats, lh_node_stats, lh_node_usage_stats, lh_stats_bio, lh_node_stats_bio, lh_node_usage_stats_bio - LHASH statistics
SYNOPSIS
#include <openssl/lhash.h>
void lh_stats(LHASH *table, FILE *out);
void lh_node_stats(LHASH *table, FILE *out);
void lh_node_usage_stats(LHASH *table, FILE *out);
void lh_stats_bio(LHASH *table, BIO *out);
void lh_node_stats_bio(LHASH *table, BIO *out);
void lh_node_usage_stats_bio(LHASH *table, BIO *out);
DESCRIPTION
The LHASH structure records statistics about most aspects of accessing the hash table. This is mostly a legacy of Eric Young writing this
library for the reasons of implementing what looked like a nice algorithm rather than for a particular software product.
lh_stats() prints out statistics on the size of the hash table, how many entries are in it, and the number and result of calls to the
routines in this library.
lh_node_stats() prints the number of entries for each 'bucket' in the hash table.
lh_node_usage_stats() prints out a short summary of the state of the hash table. It prints the 'load' and the 'actual load'. The load is
the average number of data items per 'bucket' in the hash table. The 'actual load' is the average number of items per 'bucket', but only
for buckets which contain entries. So the 'actual load' is the average number of searches that will need to find an item in the hash
table, while the 'load' is the average number that will be done to record a miss.
lh_stats_bio(), lh_node_stats_bio() and lh_node_usage_stats_bio() are the same as the above, except that the output goes to a BIO.
