• The state of the CD-ROM drive — connected or disconnected
Note: SNMP information is provided for virtual machines if their configuration files
are stored locally on the ESX Server computer. If the configuration files are stored on
an NFS-mounted drive, information for the virtual machines does not appear in the
SNMP tables.
Traps Sent by the Agent
Four SNMP traps notify you of critical events in particular virtual machines. The
affected virtual machine is identified by ID number and configuration file path. The
traps notify you
• When a virtual machine is powered on
• When a virtual machine is powered off
• When the virtual machine detects a loss of heartbeat in the guest operating
system
• When the virtual machine detects that the guest operating system’s heartbeat
has started or resumed
Note: VMware Tools must be installed in the guest operating system to support the
traps that detect loss and resumption of the guest’s heartbeat.
Note: Traps are not generated immediately when virtual machines are registered
using the VMware Management Interface. To enable trap generation, you must restart
vmware-serverd. You may restart vmware-serverd by rebooting the server
or by logging in to the console operating system as root and issuing the command
killall -HUP vmware-serverd
Installing and Running the ESX Server SNMP Agent
The SNMP agent is installed by default when you install ESX Server. The executables
and supporting files are installed in several subdirectories under /usr.
The agent is not run by default. To run the agent, set it to start automatically when the
system boots using the VMware Management Interface. To do so, follow these steps:
1. Log in to the management interface as root, click Configure System, then click
SNMP Configuration.
