The Cluster Management Console monitors clusters, generates events, and responds to events by sending notifications or performing an action. Cluster problems or changes in cluster configuration or state can cause the management server to generate an event and initiate a response.
The Cluster Management Console enables you to create and configure notification policies. The management server uses policies to determine how it responds to an event.
The event-response process occurs in the following three steps:
The management server can respond to events by sending SNMP traps, by sending e-mails or by running custom scripts.
Note Ensure that you place all custom scripts in the $data_dir/CustomScripts folder.
You must be a management server user with administrator privilege to create notification policies. Management server administrators can also view, edit, or delete their own policies or those created by other administrators. All configured policies are in effect at all times regardless of the administrator that created them.
You must specify the following conditions in a policy configuration:
Specifies the type of cluster objects to which the policy applies. The available object types are:
Specifies the object filters. It is based on the object type you have selected. The available filter conditions are:
Specifies the events to which the policy applies. The possible events vary by cluster object. If you do not specify an event condition, the policy applies to all events. The following table lists all events that the management server can monitor:
Specifies the event severities to which the policy applies. The available severities of an SNMP event are:
Notifications are recorded in a log, which is stored in the management server database. You can view a table of log entries for notification events. Each log entry is a response to an event generated by the management server.
To navigate to the event log entries
You can configure a policy to send SMTP e-mails or SNMP traps to specified recipients, such as your personal e-mail account or an SNMP console. You can also configure a policy to run a custom script each time a qualifying event occurs.
Note The management server monitors events generated only by the cluster objects that it manages. You cannot write policies for remote management servers.
