log hours is the target number of hours of plot log data to retain. A zero in this field allots the
numbers of hours based on the available memory. Note that the number of hours of log data
retained is limited by the amount of memory and disk space. If you define a large number of
clusters and servers, this will limit the amount of time over which log data can be retained. For
example, a system with 10 clusters each with 10 servers might only be able to retain about 4 hours
of log data.
Exporting Usage Statistics
You can export usage statistics, including the data collected for plotting cluster and server histories,
to a comma separated value (.csv) file that can be opened in any program (such as Excel) that
accepts comma separated data as input. The data is exported to the browser in a file with the default
name export.csv. All available statistical data is exported for the time period selected.
To export usage statistics, do the following:
1. Log into the Equalizer Administration Interface in Edit mode.
2. Select View > Export to CSV from the main menu bar; export to csv screen appears in the
right frame.

3. Select the time period for which you want to export the data from the drop-down box.
4. Select export to download the file for saving via your browser.
Configuring Custom Event Handling
You can configure Equalizer to perform certain actions when a server fails or other critical events
occur. You can forward Equalizer log information to another machine, and specify a command to
run or email to be sent when a server event occurs.
Forwarding Equalizer Log Information
You can forward Equalizer’s System Event Log (see “Displaying the System Event Log” on page
101), to another machine that is running a syslog daemon. To specify a syslog host to which you
will forward the log, follow these steps:
