1] On a Sun H/W:
1.1] On a Sun Solaris platform, the easiest way is to use the Performance
Meter (/usr/openwin/bin/perfmeter). Just right-mouse click to get to the
Properties menu and select the parameters you'd like to monitor (CPU, RAM,
network utilization, etc.)
1.2] On checking the FW-1 host disk activity, do
prompt# iostat -x 30
Look at the b values (from the whole 30 samples) and average it. If it's
more than 35% utilized then it is rather busy. Either stripe it or get a
faster disk then.
1.3] For checking network performance, do
prompt# netstat -i 30
A network output with too many collisions reduces throughput and
increases response time. Upgrade to a faster network if necessary.
1.4] On CPU and memory rules, use
prompt# vmstat 30
If the "swap" values are (1000k <= 10000k) or worse, then the system may
soon run out of virtual memory. Try to add more swap.
If the "sr" values are (200 <= 300), then the system is scanning through
memory looking for more pages to free at a high rate. This indicates that,
as well as inactive pages, active pages maybe stolen from processes.
If the "r" values are from (3 <= 5), then there is insufficient CPU power.
Jobs are spending an increasing amount of time in the queue before being
asigned to a CPU. This reduces throughput and increases response time.
2.0] On the FW-1 application, do
prompt# fw ctl pstat
If too low, edit the /etc/system file with fw:fwhmem=0x100000 (~1MB RAM).
