# Event Filter

The Event Filter is a feature that takes an automatic action when an event occurs (eg. "node detected" and "trap received"). Possible actions include sending an email.
You can specify what action to take when what type of event occurs on which node on "Add Event Filter" or "Update Event Filter" dialog box.

## Event Filter List

This page lists all event filters configured on a monitored network and allows you to view, edit and delete some or all of them. You can also create a new event filter by specifing an IP address or device name.

> Note

> > By clicking a column header (eg. "ID", "Event Name" or "Memo"), you can sort the list by the column. Order (ascending or descending) can be toggled by clicking the header.

Table 1: Event Filter List
Item Name | Contents
--- | ---
Number of items displayed on the page | Select a number of event filters displayed on a page. Options are 10, 25, 50 and All.
"Create" button | Create a new event filter. Add Event Filter page will appear.
Copy to Clipboard | Copies the event filter list (Event Name, Event Type, Node Name, Node Address, Node Device Name, Memo and Action Command) to clipboard as a tab-delimited text. It is useful when you want to copy a list to your text editor. You can filter target subnets with "Search" box. "Number of items on the page" and the current page do not affect an output.
Export to CSV file | Exports the event filter list (Event Name, Event Type, Node Name, Node Address, Node Device Name, Memo and Action Command) to a CSV file. You can filter target subnets with "Search" box. "Number of items on the page" and the current page do not affect an output.
Export to Excel | Exports the event filter list (Event Name, Event Type, Node Name, Node Address, Node Device Name, Memo and Action Command) to an Excel book file (.xlsx for Microsoft Excel 2007 or later). You can filter target subnets with "Search" box. "Number of items on the page" and the current page do not affect an output.
Print | Shows the event filter list (Event Name, Event Type, Node Name, Node Address, Node Device Name, Memo and Action Command) on another browser window or tab and opens a print dialog box. You can filter target subnets with "Search" box. "Number of items on the page" and the current page do not affect an output.
Search field | Lets you filter target subnets by keywords. The search ignores case.
ID | Shows an ID of the event filter which was automatically assigned when it was created on "Add Event Filter" dialog box.
Event Name | Shows an arbitrary name of the event which you entered on "Add Event Filter" or "Update Event Filter" dialog box.
Event Type | Select a type (Error, Alarm, Trap or Event) of the event to react. Error: Targets errors output from the SNMP Plug-in. Note When you select "Error" as the event type, "overLimit" errors are not supported. If you select "Error", leave "Node names", "Addresses", "MAC Addresses", and "Model Names" blank. Alerm: Note This item is not supported. Trap: Targets traps received from the target node. If you want to target only traps from a specific node, enter any or all of the following: "Node Names", "Addresses", "MAC Addresses", and "Model Names". If the target node is not selected, the action command set in the event filter will operate even if a trap is received from a non-monitored node. Note The events displayed under the "Trap" event type are MIB traps preinstalled in the SNMP Plug-in and traps imported by the user using the MIB compiler. Select the appropriate one. Notes: This applies to changes in the status of monitoring devices detected by the SNMP Plug-in (addition/deletion of nodes, attribute changes, etc.). Note When "Notes" is selected as the event type, "nop" and "test" are not supported in the event.
Node Address | Shows addresses of the target node. Multiple items are delimited by commas.
Node Device Name | Shows device names of the target nodes. Multiple items are delimited by commas.
Notes | Shows an arbitrary memo strings which you input on "Add Event Filter" or "Update Event Filter" dialog box.
Action Command | Shows an action to take upon when the event occurs. Multiple items are delimited by commas. Its ID is shown in parenthesis.
"Edit" button | Opens Update Event Filter page for the event filter.
"Details" button | Opens Event Filter Details page for the event filter.
"Delete" button | Opens "Delete Event Filter" dialog box. Clicking "Yes" in the dialog box deletes the event filter. Click "No" or "Close (x)" button at the top left of the dialog box allows you to cancel the delete operation and goes back to "Event Filter List" page.
Page Navigation | Lets you view a specific page of the list. First The first page is displayed. Previous Displays the page immediately before the current display page. Page Number Click the number to display the corresponding page. The currently displayed page is highlighted with a gray button background. Next Displays the next page after the currently displayed page. Last Display the final page.

## Add Event Filter

You can create and add a new event filter on this page.
An event filter runs an action command when a specific event occurs on a target node.
Target nodes for an event filter are all nodes which meet all of the following specified criteria.

- Node Name
- Node's IP Address
- Nodes' MAC Address (Not Supported)
- Node Device Name

Even when you specify multiple conditions for some of the criteria, only nodes matching all the criteria are selected as targets.
For instance,

- Node Name matches Node A and B
- IP Address matches Node B and C

Then only Node B becomes a target for an action command.
If you want to run the action command on all of the node A, B and C, create two separate event filters, one matches Node Name and the other matches IP Address.

> Note

> > Currently, MAC Address is not supported for the criteria of target node.

Note that you have to create an action command using Action Command before creating an event filter.
