vs_corexl_check: a tool for a quick overview of VSX CoreXL allocation

[Alex-]

Here's a tool to quickly check the CoreXL allocation of all your VS.

Copy it on your VSX gateway and chmod+x, make sure to run it on the standby unit first to ensure it doesn't interfere with your systems.

It will take into account that you can have non-contiguous Virtual System ID. A sample output is visible below the code.

Developed on R80.40 VSX, likely compatible with upper versions.

#!/bin/bash

System variable definitions
---------------------------

t=0             #Assigned CoreXL instance counter
array_offset=1  #Since arrays begin with an index of 0 but VS count starts at 1
array_index=0   #Base array index is 0

#Initialize display and arrays
clear
echo "VSX CoreXL allocation summary"
echo "-----------------------------"
printf "\n"

readarray -t vs_index < <(vsx stat -v | awk '{if ($3 == "S") print $1}')
readarray -t vs_name < <(vsx stat -v | awk '{if ($3 == "S") print $4}')
declare -p vs_list &>/dev/null
declare -p vs_name &>/dev/null

#Initialize for loop and match array index

for i in ${vs_index[@]}
do
evaluator=$(($array_index+1))


#Verifiy if there is not a gap in VS index

if [[ ! " $evaluator -eq  $array_index " ]]; then
array_index=$(($array_index + 2))
fi

#Display results

corecount=(`cpwd_admin list -ctx $i | grep _wd | awk {'print $11'}`)
conns_count=(`vsx stat -l $i | grep peak | awk '{print $3}'`)
conns_limit=(`vsx stat -l $i | grep limit | awk '{print $3}'`)
conns_ratio=(`echo "scale=2; ($conns_count / $conns_limit) * 100" | bc`)
if (( $(bc <<< "$conns_ratio<=75") )); then conn_color=2; elif
 (( $(bc <<< "$conns_ratio>75 && $conns_ratio<=85") )); then conn_color=3; else
 conn_color=1; fi

echo "Virtual System ID $i with name ${vs_name[$array_index]} has been assigned $corecount CoreXL instances"
echo "Peak connections#: $conns_count"
echo "Connections limit#: $conns_limit"
echo "Connections ratio: $(tput setaf $conn_color) $conns_ratio% $(tput setaf 7)"
echo "--"
array_index=$(($array_index+$array_offset))
t=$(($t + $corecount))
done
printf "\n"
echo "A total of $t CoreXL instances have been assigned between all virtual systems."

Code has been updated to also provide connections peak/limit per VS and provide a ratio with percentage, below 75%: OK, green, between 75% and  85% Warning, yellow, above 85% Critical, red, probably time to update that connections limit.

Can confirm this works on R81.10 with JHFA45 VSX system.
