Hi,

Sorry in advance that I am emailing the users list and not the biz list I
think I will find my target audience here. We are looking to hire a consultant to help us figure out an issue. We are having what seems are
“random load” issues with bare metal boxes that are dedicated to Asterisk and a few Perl AGI’s. We went after all the usual suspects (CPU IDLE, memory usage etc.). I wrote the simple bash script below to show me total calls and CPU usage of Asterisk
#! /bin/bash

for i in {1..50}
do
CALLS=$(asterisk -rx’core show calls’ | head -n 1 | awk ‘{print
$1}’)
CPU=$(top -b -n 1 | grep $(pidof asterisk) | awk ‘{print $9}’)
echo “CPU USAGE $CPU Active calls $CALLS”
done

And this was the output:

The above is with Asterisk 11.25

I am *assuming* that the load issue is being caused by the spikes generated by Asterisk. Below is the output of a different Asterisk system not running any AGI’s. It is running Asterisk 16.
