DCNM allows you to view and manage events that the DCNM server recently received from managed devices or that the DCNM server generated itself. The Event Browser allows you to view recent status events. In addition to listing events, the Event Browser provides a pie chart and a bar chart of events separated by the event severity.
DCNM also displays feature-specific status events on the Events tab that appears in the Details pane for features that can have events.
This chapter describes how to use the Event Browser and feature-specific Events tabs in Cisco Data Center Network Manager (DCNM).
Cisco DCNM allows you to view and manage recent status events. An event can be either of the following:
The Cisco 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 Cisco 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.
Note Configuring Cisco DCNM server log settings does not affect logging levels on managed Cisco NX-OS devices.
The following table shows the licensing requirements for this feature:

This section includes the following topics:
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 Cisco DCNM client.
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:
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.
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.
You can filter events in the Event Browser by the following criteria:
Note When you apply an event filter, the Events tab continues to display events when the Cisco DCNM server receives them. The filter criteria that you select only affect the Filtered Events tab.
If the message “Filter Applied” appears at the top of the Contents pane, the Cisco DCNM client is applying an event filter to the Event Browser.
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.
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.
The Filtered Events tab disappears. No message appears at the top of the Contents pane.
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 Cisco DCNM client.
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:
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, Cisco DCNM cannot display events for the object that 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:
a. Find the event in the event list.
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.
You can change the status of an event to one of the following statuses:
By default, the status of new event is Open, which is indicated in the Annotation column by a green check mark with a red slash across it.
Select an event in the Event Browser or on an Events tab for a specific feature. For more information, see the “Viewing the Event Browser” section or the “Viewing Events on an Events Tab” section.
Step 1 In the event table, right-click the selected event.
Step 2 Choose Acknowledge or Open, as needed.
The new status appears in the Annotation column for the selected event.
In the Details pane, the message about the status change appears in the Action Log field.
You can add a note to one or more events. Notes can contain 1 to 1000 characters.
Find the events to which you want to add a note. For more information, see the “Viewing the Event Browser” section or the “Viewing Events on an Events Tab” section.
Step 1 Select one or more events. Do one of the following:
Step 2 On one of the selected events, right-click and then choose Add Notes.
Step 3 Enter the note. You can enter up to 1000 case-sensitive, alphanumeric characters.
The note appears in the Action Log field for each selected event.
You can delete one or more events from the Event Browser or a feature-specific Events tab. A deleted event no longer appears in the Event Browser or on a feature-specific Events tab; however, the event remains in the events database.
For information about deleting old events from the events database, see the Fundamentals Configuration Guide, Cisco DCNM for LAN, Release 5.x .
Select an event in the Event Browser or on an Events tab for a specific feature. For more information, see the “Viewing the Event Browser” section or the “Viewing Events on an Events Tab” section.
Step 1 In the event table, select one or more events that you want to delete.
Note To select more than one event, you can click and drag across the events or you can press and hold Ctrl and click each event.
Step 2 Right-click a selected event.
The selected events disappear from the Event Browser.
This section includes the following field descriptions for Events:
The events table appears in the Event Browser and on feature-specific Events tabs.
Event details appear below the events table in the Event Browser and on feature-specific Events tabs.
Table 5-3 lists the release history for this feature.
