SNMP Troubleshooting

Following are some possible problems and solutions related to SNMP Event Forwarding. For specific

error messages, see the LifeKeeper Message Catalog.

Problem: No SNMP trap messages are sent from LifeKeeper.

Solution: Verify that the snmptrap utility is installed on the system (it is usually located in /usr/bin). If

it is not installed, install the appropriate snmp package (seePrerequisites). If it is installed in

someother location, edit the PATH variable in the file /etc/default/LifeKeeper and add the appropriate

path.

Problem: No SNMP error messages are logged and SNMP trap messages do not appear to be sent

from a LifeKeeper server.

Solution: Check to see if LK_TRAP_MGR is set to the IP address of the network management server

that will receive the traps.From the command line, use the lk_configsnmp utility with the "query"

option to verify the setting (See the lk_configsnmp(1M)man page for an example.) Or, search for

the entry for LK_TRAP_MGR in the file /etc/default/LifeKeeper.This variable must be set on

each LifeKeeper node that will generate SNMP trap messages.

LifeKeeper Event Email Notification

Overview of LifeKeeper Event Email Notification

LifeKeeper Event Email Notification is a mechanism by which one or more users may receive email

notices when certain events occur in a LifeKeeper cluster.LifeKeeper has an event notification

mechanism for registering applications that wish to be notified of specific events or alarms (see the

sendevent(5) man page). LifeKeeper can be easily enabled to send email notification of key

LifeKeeper events to a selected set of users wishing to monitor LifeKeeper activity. Additionally, a log

of each email notice issued is available via the LifeKeeper lk_log(8) utility or by using the

Viewing Server Log Filesfacility in the LifeKeeper GUI.The messages may be found in the NOTIFY

log.Refer to the lk_log(8)man page for more information about viewing the contents of the logs

from the command line.

By default, LifeKeeper Event Email Notification is disabled.Enabling this feature requires setting the

LK_NOTIFY_ALIAS environment variable defined in /etc/default/LifeKeeper. The LK_

NOTIFY_ALIAS environment variable can be set to a single email address or alias, or it can contain

multiple addresses or aliases separated by commas.To set LK_NOTIFY_ALIAS either run lk_

confignotify alias (See thelk_confignotifyalias(1M)man page for an example) from

the command line and supply the address or list of addresses that should receive email when an

event occurs or edit the defaults file /etc/default/LifeKeeper to add the email address or

address list.Search for the entry LK_NOTIFY_ALIAS= and insert the address or address list

separated by commas. Repeat this action on all nodes in the cluster that need to send email for the

selected LifeKeeper events.
