Information About Events
DCNM allows you to view and manage recent status events. An event can be either of the following:
•A status-related system message that DCNM retrieves from managed devices. For more information, see the "Logfile Requirements" section on page 1-6.
•A message generated by the DCNM server.
The DCNM client includes the Event Browser and feature-specific Events tabs that appears in the Details pane for features that can have events. The Event Browser shows all recent status events while a feature-specific Events tab shows recent status events that pertain to the feature. The DCNM client updates the Event Browser and Events tabs dynamically when it receives new events from the server.
In the Event Browser and on Events tabs, you can change the status of an event, add notes to an event, or delete an event.
In addition, the Event Browser provides a pie chart and a bar chart of events separated by the event severity. You can also delete individual events from the events database.
To control the minimum severity of event messages, you configure the logging level for Cisco NX-OS features and for DCNM server features. For more information, see the "Cisco NX-OS System-Message Logging Requirements" section on page 1-6.
Note DCNM has minimum logging level requirements for managed Cisco NX-OS devices. Logging levels on a managed device should never be lower than the minimum requirements.
For more information about DCNM server logging levels, see Chapter 17, "Administering DCNM Server Log Settings."
Note Configuring DCNM server log settings does not affect logging levels on managed Cisco NX-OS devices.
Licensing Requirements for the Event Browser
The following table shows the licensing requirements for this feature:

|---|---|
DCNM |
The Event Browser requires no license. Any feature not included in a license package is bundled with the Cisco DCNM and is provided at no charge to you. For information about obtaining and installing a DCNM LAN Enterprise license, see the "Installing Licenses" section on page 2-7. |
Prerequisites for Events
The Event Browser has the following prerequisites:
•You should be familiar with Cisco NX-OS system messages.
•Managed Cisco NX-OS devices must be configured to send system messages to the DCNM server.
Guidelines and Limitations
The Event Browser has the following configuration guidelines and limitations:
•The Event Browser and feature-specific Events tabs display only status events, which are events generated when the status of a feature or object changes. For example, configuration events do not appear in the Event Browser or on an Events tab.
•The Event Browser can display event messages that are no older than 24 hours when you start the DCNM client. By default, the DCNM client fetches from the server messages that are no older than 1 hour.
•The Event Browser can display up to 2000 events. The events database is limited by the amount of space available to the database.
•You cannot use DCNM to control the logging levels of managed Cisco NX-OS devices. For more information, see the "Cisco NX-OS System-Message Logging Requirements" section on page 1-6.
•We recommend that you delete events that you no longer need or that you have resolved. For information about deleting old events from the events database, see the "Deleting Data from the Events Database" section on page 15-6.

Viewing the Event Browser
You can use the Event Browser to view recent events and a summary chart of those events. By default, the Event Browser shows events that occurred up to 1 hour prior to starting the DCNM client. For more information, see the "Configuring the Maximum Age of Events Fetched from the Server" section on page 4-15.
DETAILED STEPS
To view the Event Browser, follow these steps:
Step 1 From the Feature Selector pane, choose Event Browser.
The event table appears in the Contents pane. A summary chart appears above the Feature Selector pane.
Step 2 (Optional) If you want to change the summary chart that appears, above the Feature Selector, choose one of the following Chart Type options, as needed:
•Bar Chart
•Pie Chart
The colors of the chart correspond to event severity levels, as indicated in the legend that appears above the chart.
Step 3 (Optional) If you want to sort or filter events, you can use one or more of the filtering features as described in the following table:
Step 4 (Optional) If you want to view details about a specific event, follow these steps:
a. Find the event in the event list.
b. Click the event.
c. Expand the Details pane, if necessary.
Details about the selected event appear in the Details pane.
d. (Optional) To read notes and messages about status changes to the event, read the information in the Action Log field.
Applying and Removing an Event Filter
You can filter events in the Event Browser by the following criteria:
•Event date and time—By default, the DCNM client displays all events received after you started the DCNM client and for a configurable number of hours prior to starting the DCNM client (for more information, see the "Configuring the Maximum Age of Events Fetched from the Server" section on page 4-15).
•Event severity—By default, the DCNM client displays events of all severities.
Note When you apply an event filter, the Events tab continues to display events when the DCNM server receives them. The filter criteria that you select only affect the Filtered Events tab.
BEFORE YOU BEGIN
If the message "Filter Applied" appears at the top of the Contents pane, the DCNM client is applying an event filter to the Event Browser.
DETAILED STEPS
To apply or remove an event filter in the Event Browser, follow these steps:
Step 1 View events in the Event Browser (see the "Viewing the Event Browser" section).
Step 2 If you want to apply an event filter, follow these steps:
a. From the menu bar, choose View > Event Filter.
b. Check the Apply Filter check box.
c. Configure the filter criteria.
d. Click OK.
A Filtered Events tab appears in the Event Browser. The tab displays the events that match the filtering criteria that you specified. The message "Filter Applied" appears at the top of the Contents pane.
Step 3 If you want to remove an event filter, follow these steps:
a. From the menu bar, choose View > Event Filter.
b. Uncheck the Apply Filter check box.
c. Click OK.
The Filtered Events tab disappears. No message appears at the top of the Contents pane.
Viewing Events on an Events Tab
You can view feature-specific events on the Events tab that appears in the Details pane for a feature. By default, an Events tab shows events received up to 1 hour prior to starting the DCNM client. For more information, see the "Configuring the Maximum Age of Events Fetched from the Server" section on page 4-15.
BEFORE YOU BEGIN
Typically, the Events tab appears when, in the Summary pane, you select an object that can have events associated with it. For example, if you select Interfaces > Physical > Ethernet from the Feature Selector pane, the Summary pane displays devices. Devices contain slots, and slots contain Ethernet ports. When you select a device, slot, or port, the Details pane displays an Events tab.
What you select in the Summary pane affects which events are shown in the tab. Continuing the Ethernet interface example, the scope of the events in the Events tab depends on what you select, as follows:
•Device—Events that pertain to the selected device, any slot within the device, and any Ethernet interface within the slot.
•Slot—Events that pertain to the selected slot and to any Ethernet interface within the slot.
•Port—Events that pertain to the selected Ethernet interface.
DETAILED STEPS
To view an event on an Events tab, follow these steps:
Step 1 From the Feature Selector pane, choose the feature for which you want to view events.
For example, choose Interfaces > Physical > Ethernet.
Step 2 From the Summary pane, select an object.
The Events tab appears in the Details pane. In the Events tab, the events table appears.
Note If no Events tab appears, then DCNM cannot display events for the object you selected.
Step 3 (Optional) If you want to sort or filter events, you can use one or more of the filtering features as described in the following table:
Step 4 (Optional) If you want to view details about a specific event, follow these steps:
