Ipswitch WhatsUp Gold User Guide
Daily records are a summarization of the 24 hourly records for that day. As time
progresses, information in the database about a particular performance monitor gets
less and less granular, or specific, until reaching the daily record expiration limit at which
point the data is lost and replaced by new, incoming data. By adjusting the retention
settings for performance monitor data, you can affect how much space is occupied by a
table's data. As you decrease the time period that records are kept, you decrease the
amount of space needed to store those records.
For information on changing data retention settings, see Changing how long report data
is stored (on page 810) and the Program Options - Report Data (on page 815) dialog help.
Note: Changing these settings affects all the performance monitor data collected by
WhatsUp Gold. This includes CPU, Disk, Memory, Ping Latency & Availability, Interface
Utilization (collecting data for All Interfaces, Active Interfaces, Specific Interfaces, Custom
Active Interfaces, and Interface Errors and Discards), Printer, VoIP, and any data collected by
custom performance monitors you have created.
Tip: You can use the Alert Center to set database threshold alerts for WhatsUp Gold and Flow
Monitor. For more information, see Configuring a WhatsUp Health threshold (on page 795).
Reducing PassiveMonitorActivityLog
The PassiveMonitorActivityLog table stores Passive Monitor data collected by SNMP Trap,
Syslog, and Windows Event Log monitoring.
In most cases, a very large table is the result of WhatsUp collecting unnecessary or unwanted
passive monitor data.
1. Verify Passive Monitor Listener configuration
The first step is to ensure you are only collecting data for passive monitors you have explicitly
configured for your devices. To do this, ensure that for the both the SNMP Trap Listener and
the Syslog Listener, you are not accepting unsolicited messages. You can verify this
configuration in Program Options.
To verify Passive Monitor Listener configuration:
1 From the main menu of the WhatsUp Gold console, select Configure > Program
Options. The Program Options dialog appears.
2 Click Passive Monitor Listeners. The Program Options - Passive Monitor Listeners
dialog appears.
3 Select SNMP Trap, then click Configure. The SNMP Listener Configuration dialog
appears.
4 Ensure that Accept unsolicited SNMP Traps is not selected, then click OK. The Program
Options - Passive Monitor Listeners dialog appears.
5 Select Syslog, then click Configure. The Syslog Listener Configuration dialog appears.
6 Ensure that Accept unsolicited passive monitors is not selected, then click OK. The
Program Options - Passive Monitor Listeners dialog appears.
7 Click OK to exit Program Options.
