Configuring Custom Event Handling; Forwarding Equalizer Log Information; Specifying A Command To Run On An Event - Coyote Point Systems E350GX Installation And Administration Manual

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 log entries from Equalizer's System Event Log (see "Displaying the System Event Log" on page
186), to another machine that is running a system logging daemon. When this option is enabled, each system event
message is sent to the remote system via a UDP datagram by the syslogd daemon running on Equalizer. To specify a
remote system logging host, follow these steps:
1. Log into the Equalizer Administration Interface (see "Logging In" on page 52).
2. Select
Equalizer > Monitoring > Events
Figure 40 The Events tab - logging field
3. In the field, enable the
logging
4. In the text box, type the hostname or IP address of the machine to which you want to forward
syslog host
syslog messages. The system you specify must be running a system logging daemon (such as syslogd) that is
configured as a system logging host; see the documentation for the operating system running on that system for
more information.
5. Click the button.
commit
Note – The remote syslog facility on Equalizer sends all syslog messages to the remote host, including low
priority messages (e.g., information only messages) that are not displayed when viewing the operating system log
via the Administrative Interface. You should edit the syslog configuration on the remote host to filter incoming
messages so that only the priority levels in which you are interested are recorded on the remote system.

Specifying a Command to Run on an Event

You can configure Equalizer to run a command that you specify (such as running a custom shell script) whenever
certain events occur. The following events trigger the specified command:
• Failure of a server
• Restoration of a failed server
• Failure of a server agent
• Restoration of a server agent
• Failover in a high-availability Equalizer pair
