Hi All,
Please help me.
I have tested the ae_graph_pm.pl script. And found out that the only place its
taking high CPU utilization is during a function call
RRDs::graph( "$graphPath/$curName",
"--start=$startTime",
"--end=$g_time",
"-a","PNG",
"--title=$title",
"--vertical-label=$yaxis",
"--width=500",
"--height=100",
"--alt-autoscale-max",
"--lower-limit=0",
@defs,
@cdefs,
@lines,
"COMMENT:\\n",
"COMMENT: $comment\\n"
);
Which is an API given by 3rd party rrd tool.
This function is called in a loop for the number of times the graph time
interval is defined multiplied by number of blades.
Ex. Lets say for each balde we have 8 intervals defined 30mins, 3hr, 12hr,
24hr, 1 day, 3 day, 15day, 31day and currently the number of blades is 12

-rw-r--r-- 1 ins insgroup 3420 Dec 11 17:17 System_graph6_31day.png

-rw-r--r-- 1 ins insgroup 3530 Dec 11 17:17 System_graph6_24hr.png
-rw-r--r-- 1 ins insgroup 3462 Dec 11 17:17 System_graph6_3hr.png
-rw-r--r-- 1 ins insgroup 3604 Dec 11 17:17 System_graph6_60day.png
-rw-r--r-- 1 ins insgroup 3402 Dec 11 17:17 System_graph6_3day.png
I.e. it is called 8*12 times per $updateGraphInterval = 300 ( per 5 minutes).
So the High CPU utilization vary from 28% to 49%
Low CPU Utilization vary from 0.5% to 1%
As observed from the top command.
Thanks & Regards
Krishna
