4.4 Monitoring Access Gateway Alerts

The Access Gateway has been programmed to issue events to various types of systems (such as a Novell® Audit server or a Syslog server) so that the administrator can be informed when significant changes occur that modify how the Access Gateway is performing. For information about auditing and audit events, see Section 4.5, Enabling Access Gateway Audit Events. This section describes how to use the following types of alerts:

4.4.1 Reviewing Java Alerts

The Alerts page allows you to view information about current Java alerts and to clear them. An alert is generated whenever the Access Gateway detects a condition that prevents it from performing normal system services.

  1. In the Administration Console, click Devices > Access Gateways > [Name of Server] > Alerts.

    Monitoring alerts
  2. To delete an alert from the list, select the check box for the alert, then click Acknowledge Alert(s). To remove all alerts from the list, click the Severity check box, then click Acknowledge Alert(s).

  3. Click Close.

  4. (Optional) To verify that the problem has been solved, click Access Gateways > [Server Name] > Health > Update from Server.

4.4.2 Configuring Access Gateway Alerts

You can configure alerts for individual Access Gateways and for Access Gateway clusters. To set up notification for these types of alerts, see the following sections:

Access Gateway Alerts

For a Access Gateway, this option allows you to send notification of generated system alerts to the Administration Console, to a Syslog server, to a log file, or to a list of e-mail recipients.

  1. In the Administration Console, click Devices > Access Gateways > Edit > Alerts.

    Configuring Alerts
  2. To add a new profile, click New.

  3. Specify a name for the profile, then click OK.

  4. To select the alerts for notification, select one or more of the following:

    Alert

    Description

    Connection Refused

    Generated when a connection is refused.

    Proxy Initialization Failure

    Generated when the Embedded Service Provider fails to initialize.

    System Up

    Generated each time the Access Gateway is started.

    System Down

    Generated each time the Access Gateway is stopped.

    Configuration Changed

    Generated each time the configuration of the Access Gateway is modified.

    DNS Server Not Responding

    Generated each time the DNS stops responding.

    DNS Server Is Now Responding

    Generated each time the DNS server comes up.

    DNS Parent Address Invalid

    Generated when the IP address of DNS parent is invalid.

    DNS Resolver Initialization Failure (10 seconds)

    Generated when the DNS resolver initialization fails.

    DNS Resolver Initialization Failure (2 minutes)

    Generated when the DNS resolver initialization fails.

    Failure in Audit, Stopping Services

    Generated when the audit server has failed, and the Access Gateway has been configured to stop services.

    To configure the Access Gateway to continue when auditing services are not available, click Auditing > Novell Auditing, deselect the Stop Services on Audit Server Failure option, then click Apply.

    Failure in Audit, Will lose events, but continuing services

    Generated when the audit agent has failed. The Access Gateway continues to run, but no audit events are generated.

    As a workaround while solving this problem, you can enable proxy service logging (see Section 4.2, Configuring Proxy Service Logging). The common and extended log files provide some details on the HTTP traffic.

    If you do not want the Access Gateway to run without generating events, you need to manually shut down the Access Gateway.

    Failure in Audit, Server is offline

    Generated when the audit agent is unable to contact the audit server. When this condition occurs, the audit agent uses local caching for the audit events.

    Do not allow this condition to continue indefinitely. The Access Gateway soon reaches the limits of its local cache. If this happens, events can be lost and the Access Gateway might need to stop services.

    For troubleshooting information, see “Troubleshooting Novell Audit” in the Novell Audit Administration Guide.

  5. To send alerts to the Administration Console, select the Send to Device Manager check box.

  6. To send alerts to a log file, click New in the Send to Log File section, specify a name for the log profile, then click OK.

    1. Configure the following Log File details:

      • Log File Name: Specify a name for the log file and a path where the file should be stored.

      • Max File Size: Specify a maximum size in KB for the log file. The size can be from 50 to 100000 KB. Specify 0 to indicate that there is no maximum file size.

    2. Click OK.

  7. To enable e-mail notification click New in the Send Email Notifications section, specify a name for the e-mail profile, then click OK.

    1. Configure the following e-mail details:

      • E-mail Recipients: To add a recipient to the list, click New, specify the e-mail address of the recipient, then click OK. You can add multiple e-mail addresses. To delete a recipient, select the user’s email address, click Delete, then click OK.

      • Mail Exchange Servers: To add a mail server, click New, specify the IP address or the DNS name of the mail exchange server, then click OK. You can add multiple mail exchange servers. To delete a server, select the server, click Delete, then click OK.

    2. Click OK.

  8. To enable syslog alerts click New in the Send to Syslog section, specify a name for the Syslog profile, then click OK.

    1. Configure the following syslog details:

      • Facility Name: Specify a facility name for the Syslog server. It can be any name from local0 to local7. If you specify local0 as your facility name, the alerts are stored at \var\logs\ics_dyn.log. The Access Gateway Appliance uses local0 for normal logging information. Therefore, it is not recommended to specify local0 as your facility name.

    2. Click OK.

  9. To enable an alert action profile, select the action profile, click Enable, then click OK.

    The action to send the alerts to a log file, to email addresses, or to a syslog file is not performed until the action profile is enabled.

  10. On the Alert Profiles page, verify that the Alert Profile you have created is enabled.

  11. To save your modifications, click OK twice.

  12. On the Access Gateways page, click Update.

Access Gateway Cluster Alerts

To view information about current alerts for all members of a cluster:

  1. In the Administration Console, click Devices > Access Gateways > [Name of Cluster] > Alerts.

  2. Analyze the data displayed in the table.
