How are network metrics calculated by cdm probe on Solaris platform
cdm 6.30
Solaris 10.x/ 11.x
cdm probe uses a combination of dladm and kstat for collecting the network data for solaris system
"dladm show-link" to get dataLink details and and "kstat -p -c net -n" to fetch the data
How to manually verify with commands:
Can check the output of command
dladm show-link
and
dladm show-link | awk '{print $1}'
Also below shell script(example file name:network.sh) which can be run on solaris environment within a temporary directory.
#!/usr/bin/bash
dladm show-link | awk '{print $1}' > dataLinksInfo
filename="dataLinksInfo"
while true
do
echo "New iteration"
while read -r line; do
name="$line"
skipiDisk="LINK"
if [[ "$name" == "$skipiDisk" ]]
then
echo "Skiping datalink name as $name"
else
kstat -p -c net -n $name | grep 'bytes64'
fi
done < "$filename"
sleep 3
done
It will show the obtes64 and rbytes64 details on command prompt which is published as inbound , outbound and total network metrics.
