Assumptions:

Understanding for Shell script

UnderStand Fusion MiddbleWare

Script:

This script is tested in EBS 12.2 Environment. You can change values as per your environment.

#!/bin/bash

#set -x

. /u01/install/APPS/EBSapps.env run

# Set WebLogic Environment Variables

export MW_HOME=/u01/install/APPS/fs1/FMW_Home

export WL_HOME=$MW_HOME/wlserver_10.3

export DOMAIN_HOME=$MW_HOME/user_projects/domains/EBS_domain

export PATH=$PATH:$WL_HOME/common/bin

# WebLogic Admin Server credentials

ADMIN_URL="t3://apps.example.com:7001"

USERNAME="weblogic"

PASSWORD="welcome1"

# Temporary file to store WLST script

WLST_SCRIPT="/tmp/check_wls_status.py"

# Temporary file to store WLST script

WLST_SCRIPT="/tmp/check_wls_status.py"

# Colors for output

RED='\033[0;31m'

NC='\033[0m' # No Color

# Function to create WLST script for checking server status

create_wlst_script() {

  cat <<EOF > $WLST_SCRIPT

connect('$USERNAME', '$PASSWORD', '$ADMIN_URL')

domainRuntime()

# Function to check the status of a server

def check_server_status(serverName):

    cd('/ServerLifeCycleRuntimes/' + serverName)

    state = cmo.getState()

    if state == "RUNNING":

        print('Server: ' + serverName + ' - State: ' + state)

    else:

        print('DOWN: ' + serverName + ' - State: ' + state)

# List of servers to check

servers = cmo.getServerLifeCycleRuntimes()

for server in servers:

    serverName = server.getName()

    check_server_status(serverName)

disconnect()

exit()

EOF

}

# Function to execute WLST script and process the output

execute_wlst_script() {

  $WL_HOME/common/bin/wlst.sh $WLST_SCRIPT | while IFS= read -r line; do

    if [[ $line == DOWN:* ]]; then

      echo -e "${RED}${line}${NC}"

    else

      echo "$line"

    fi

  done

}

# Main function to monitor WebLogic servers

monitor_weblogic() {

  echo "Monitoring WebLogic Admin and Managed Servers..."

  create_wlst_script

  execute_wlst_script

  rm -f $WLST_SCRIPT

}

# Call the main function

monitor_weblogic

Execution of Script:

sh monitor_weblogic.sh
