Adjust SNMP community string and OID definitions as needed based on your environment. /* !/bin/bash /* Usage: ./vmware_inventory.sh <ESXi_host_IP> /* Check if IP address is provided if [ -z "$1" ]; then echo "Usage: $0 <ESXi_host_IP>" exit 1 fi /* Define ESXi host IP address ESXI_HOST="$1" /* SNMP community string SNMP_COMMUNITY="public" /* SNMP OID definitions MEMORY_USAGE_OID="HOST-RESOURCES-MIB::hrStorageUsed.1" HARDWARE_DETAILS_OID="VMWARE-MIB::vmwHwManufacturer.0" PROCESSOR_USAGE_OID="HOST-RESOURCES-MIB::hrProcessorLoad.1" VIRTUAL_MACHINES_OID="VMWARE-MIB::vmwVmName" /* Function to perform SNMP query snmp_query() { snmpwalk -v2c -c "$SNMP_COMMUNITY" "$ESXI_HOST" "$1" | awk -F ": " ' {print $2} ' } /* Retrieve memory usage MEMORY_USAGE=$(snmp_query "$MEMORY_USAGE_OID") /* Retrieve hardware details HARDWARE_DETAILS=$(snmp_query "$HARDWARE_DETAILS_OID") /* Retrieve processor usage PROCESSOR_USAGE=$(snmp_query "$PROCESSOR_USAGE_OID") /* Retrieve virtual machines VIRTUAL_MACHINES=$(snmp_query "$VIRTUAL_MACHINES_OID") /* Display gathered information echo "Memory Usage: $MEMORY_USAGE" echo "Hardware Details: $HARDWARE_DETAILS" echo "Processor Usage: $PROCESSOR_USAGE" echo "Virtual Machines:" echo "$VIRTUAL_MACHINES" ======================================================================= /*# Define SNMP community string const SNMP_COMMUNITY = "public"; /*# Define SNMP OID definitions const MEMORY_USAGE_OID = "HOST-RESOURCES-MIB::hrStorageUsed.1"; const HARDWARE_DETAILS_OID = "VMWARE-MIB::vmwHwManufacturer.0"; const PROCESSOR_USAGE_OID = "HOST-RESOURCES-MIB::hrProcessorLoad.1"; const VIRTUAL_MACHINES_OID = "VMWARE-MIB::vmwVmName"; /*# Function to perform SNMP query sub snmpQuery(host, oid) { return SNMP::get(host, SNMP_COMMUNITY, oid); } /*# Retrieve memory usage const memoryUsage = snmpQuery(node.ipAddress, MEMORY_USAGE_OID); /*# Retrieve hardware details const hardwareDetails = snmpQuery(node.ipAddress, HARDWARE_DETAILS_OID); /*# Retrieve processor usage const processorUsage = snmpQuery(node.ipAddress, PROCESSOR_USAGE_OID); /*# Retrieve virtual machines const virtualMachines = snmpQuery(node.ipAddress, VIRTUAL_MACHINES_OID); /*# Output gathered information console.print("Memory Usage: " + memoryUsage); console.print("Hardware Details: " + hardwareDetails); console.print("Processor Usage: " + processorUsage); console.print("Virtual Machines: " + virtualMachines);
