You can check SNMP timeout and retry values from the
Administration→Mediation menu. Click on the Mediation Security tab button.
Procedure 10-12 Problem: Statistics are rolling over too quickly
Statistics database tables roll over, or lose statistics during an interval, if the tables fill
before all statistics are collected or the next collection interval starts. To ensure
sufficient statistics collection, consider the following:
• the statistics table size, depending on the configuration specified in the
5620 SAM | 5650 CPAM Installation and Upgrade Guide
• the number of statistics collected, the number of objects with statistics
collection enabled, and the frequency of statistics collection, as specified in
the 5620 SAM User Guide
• the OSS application requests data from the statistics tables less frequently
than the configured roll over interval
• FTP must be enabled on the managed device in order for the 5620 SAM to
retrieve statistics.
Alcatel-Lucent recommends that statistics collection planning includes the following
considerations to prevent the loss of statistics data.
• measure the rate of statistics collection over a sufficient time interval
• determine the appropriate collection interval and statistics database table
size based on individual network configurations
• ensure that the polling interval is sufficient for polled statistics
Procedure 10-13 Problem: Unable to receive alarms on the 5620 NM
from the 5620 SAM
Check that the 5620 NM AS tool is properly configured to receive 5620 SAM alarms.
1 Ensure that the integration software is properly configured, as described in the
5620 SAM | 5650 CPAM Installation and Upgrade Guide.
2 Configure the param.cfg file on the 5620 NM to ensure that alarms are forwarded
from the 5620 SAM to the 5620 NM AS tool:
Caution — When LAN performance is poor, increasing timeout values
may mask an underlying problem. Increasing the SNMP timeout value in
an environment where collisions are frequent reduces performance.
Timeout values should be based on typical network response times
Check LAN communication issues, as specified in chapter 7. If problems
persist, collect log information as specified in Procedure 2-1 and
contact your Alcatel-Lucent support representative.
