Configuring SNMP Alarms

Configuring SNMP Alarms

This section includes procedures for configuring SNMP alarms. It covers the following topics:

• Enabling an SNMP Alarm

• Setting the Severity of the SNMP Alarm

• Disabling an SNMP Alarm

Enabling an SNMP Alarm

After you enable an SNMP alarm, the NetScaler generates trap messages when certain events occur. Some alarms are enabled by default.

To enable alarm using the configuration utility

1. In the navigation pane, expand System, expand SNMP, and click Alarms. The Alarms page appears in the details pane.

2. On the Alarms page, select a disabled SNMP alarm that you want to enable, for example, LOGIN-FAILURE.

3. Click Enable.

To enable alarms using the NetScaler command line

At a NetScaler command prompt, type:

set snmp alarm LOGIN-FAILURE –state ENABLED

Setting the Severity of an SNMP Alarm

There are five severity types (tags): Critical, Major, Minor, Warning, and Informational. A trap is sent only when the severity of the alarm matches the severity specified for the trap.

To set the severity of the alarm using the configuration utility

1. In the navigation pane, expand System, expand SNMP, and click Alarms. The SNMP Alarms page appears in the details pane.

2. Select the alarm for which you want to set the severity, for example, LOGIN-FAILURE.

3. Click Open. The Configure SNMP Alarm dialog box appears.

4. In Severity, select a severity option, for example, Major.

5. Click Ok.

To set the severity of the alarm using the NetScaler command line

At a NetScaler command prompt, type:

set snmp alarm LOGIN-FAILURE -severity Major

Disabling an SNMP Alarm

If you disable an SNMP alarm, the NetScaler will not generate trap messages when corresponding events occur. For example, if you disable the Login-Failure SNMP alarm, the NetScaler will not generate a trap message when a login failure occurs.

To disable an SNMP alarm using the configuration utility

1. In the navigation pane, expand System, click SNMP, and click Alarms. The Alarms page appears in the details pane.

2. In the Alarms page, select an SNMP alarm that you want to disable, for example, LOGIN-FAILURE.

3. Click Disable.

To disable an SNMP alarm using the NetScaler command line

At a NetScaler command prompt, type:

set snmp alarm LOGIN-FAILURE –state DISABLED

Configuring Syslog

You can customize logging of NetScaler and Access Gateway Enterprise Edition access events for the needs of your site. You can direct these logs either to files on the NetScaler or to external log servers. The NetScaler uses the Audit Server Logging feature for logging the states and status information collected by different modules in the kernel and by user-level daemons. For more information about the Audit Server Logging feature, see the “Audit Server Logging” chapter in Citrix NetScaler Administration Guide.

Syslog is used to monitor a NetScaler and log connections, statistics, and so on. You can customize the two logging functions for system events messaging and syslog. The NetScaler’s internal event message generator passes log entries to the syslog server. The syslog server accepts these log entries and logs them.
