Information About Events
Cisco DCNM allows you to view and manage recent status events. An event can be either of the following:
-
A status-related system message that Cisco DCNM retrieves from managed devices. For more information, see the
Fundamentals Configuration Guide, Cisco DCNM for LAN, Release 7.1.x
.
-
A message generated by the Cisco DCNM server.
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.
Using the Event Browser and Events Tabs
This section includes the following topics:
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 Cisco DCNM client.
DETAILED 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:
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:
Event Sorting and Filtering Feature

In the Event Browser toolbar, enter the text that you want to use to filter the events.
The Event Browser shows only the events that contain the text that you enter.
Tip To configure quick filtering options, use the drop-down list of the Event Browser toolbar.

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 Cisco DCNM client displays all events received after you started the Cisco DCNM client and for a configurable number of hours prior to starting the Cisco DCNM client (for more information, see the Configuring the Maximum Age of Events Fetched from the Server).
-
Event severity—By default, the Cisco DCNM client displays events of all severities.
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.
BEFORE YOU BEGIN
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.
DETAILED 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 Cisco DCNM client.
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
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:
