130 Event Management and Best Practices
The NetView IBM Tivoli Enterprise Console Adapter forwards two new events
to IBM Tivoli Enterprise Console to allow correlation and an increase in
severity for critical resources. The state correlation engine built in the NetView
IBM Tivoli Enterprise Console adapter is used for this purpose.
Upon receipt of a TEC_ITS_NODE_STATUS or TEC_ITS_ROUTER_STATUS
event where the status is DOWN or MARGINAL and the affected node owns
any "isITM_*" attributes, a TEC_ITS_NODE_SERVICE_IMPACT event is
generated for each IBM Tivoli Monitoring service attribute found on the node.
This includes the node host name and the affected service.
Upon receipt of a TEC_ITS_SUBNET_CONNECTIVITY where the status is
UNREACHABLE and the affected nodes own one of the "isITM_*" attributes,
a TEC_ITS_SUBNET_SERVICE_IMPACT event is generated for each
affected IBM Tivoli Monitoring-related service.
4.4.3 First failure data capture
The first failure data capture (FFDC) function provides a means to collect data
after the first failure of a Tivoli NetView daemon. The FFDC subsystem
automatically collects and archives necessary data at the time of failure. You can
use this information to analyze the problem, or you can send the data archive to
IBM Customer Support.
The FFDC subsystem does not collect any data in case a daemon is stopped in a
friendly manner using the ovstop command.
FFDC increases the tracing and logging activity and can affect your initial
discovery. Because an initial discovery occurs rather seldom in a working
environment, the overall impact of FFDC should be moderate.
To turn off the FFDC function permanently, use the following procedure:
1. Edit the /usr/OV/conf/FFDC/autotrace.properties file.
2. Set the following property to TRUE:
Use the following procedure to turn off and on the FFDC function for the current
Tivoli NetView session. The FFDC function remains off until the Tivoli NetView
product is stopped and restarted.
Note: At the time this book was written, no particular information about the
atctl command was available. In general, you use this command to control
(start or stop) the FFDC subsystem.
