Reducing performance monitor records
This option examines the number of records in the performance monitor data tables. A large
number of records in these tables can potentially cause performance problems in WhatsUp
when writing performance monitor polling data and when viewing polling data in the web
interface. You can decrease the quantity of records in these tables in several ways:
1 Enable monitoring only for the important devices in your network.
You should collect performance monitor information from only those devices that are a
concern. You can do this from the Device Properties - Performance Monitors (on page 121)
dialog.
2 Increase the polling interval for performance monitors on non-critical devices.
By changing how often WhatsUp Gold collects data from devices, you can decrease the
amount of storage needed in the database for the monitor's records. This can be done
on a per-device basis from within the Device Properties - Performance Monitors dialog
or for all devices using the Bulk Field Change feature. We recommend setting each
device manually as this allows for separate intervals and will not change the collection
type for the monitor on the device. For more information, see Configuring the Interface
Utilization Monitor collection settings (on page 256) and the Bulk Field Change -
Performance Monitor (on page 820) dialog help.
Note: By setting a longer polling interval, you are decreasing the granularity of the
performance monitor data on a device. For example, a device is set to collect utilization data
every ten minutes for an hour. If there is a sustained period of 100% utilization for 10
minutes, while the rest of the hour shows 0% utilization, the period of 100% utilization is
visible in the device's reports, followed by 0% utilization for the rest of the hour. But, if that
same device is only collecting data once every 20 minutes, you only see 50% utilization of
the interface during that 20-minute sample period.
3 Change the data retention settings for all performance monitors configured in WhatsUp
Gold.
By default, WhatsUp Gold keeps raw performance monitor records for 1 day, hourly
records for 30 days, and daily data for 1 year. Raw data is records in the database that
contain actual values retrieved from a device during the poll of a performance monitor.
This is the most granular data this table contains about performance monitor
information on a device. Hourly records are an aggregate of an hour's worth of raw
records, summarized and averaged into a single record. Instead of seeing each poll as a
separate data point, the individual data points are reduced to a single, hourly summary.
