Working with Clipart object

Clipart object are predefined objects that can be loaded in the Drawing pane. The clipart are already advanced images like (country MAP,building, devices,etc.) that do not need to be assembled.It can also be parts like connectors and chassis that have to be assembled to build a complex object like a network equipment.

The LoriotPro software uses a fixed directory structure that is directly visible from the object navigator pane.To extend the clipart library you could create other subdirectory at the the /bin/card level and add to it your own clipart files (Emf and Wmf format only. After that, these clipart objects become available and a drag and drop is possible from the object navigator pane to the edit window.

Warning: An Active View Object has an internal link to its associated clipart. This link contains the directory path to the clipart. Clipart should remain imperatively in their original directory. Doing modifications to the directory structure will damage the current defined Active View.

Typically the physical view of all equipment is composed of multiple cliparts objects that have to be imported in the drawing view.

Clipart like other objects could be Active to restore the current state of a directory object or a SNMP OID value. On the upper example each physical port form the router is a clipart with a dynamic behavior. Refer to the case study of this documentation for using cliparts

Vu-meters are a type of clipart objects that have more features than a simple Clipart object. The Vu-meter is able to display the variation of an SNMP variable in a visual analogical meter.

To add this kind of Clipart to an existing view, drag and drop the Analogic meter icon the Object Navigator pane to the drawing window. Next open the property windows and select the clipart symbol. The Vumeter choice opens a window asking you to select a skin for your Vumeter.

The selected Vu meter is displayed

In property window under the Vu meter tab you can define the min and max value and add a legend

We choose to enter %CPU as Unit Text

We define the value to display from the Dynamic aspect tab. In the following example with perform a request on the CPU load of a Cisco router. The SNMP request is getipoid defip old-cisco-cpu-mib:busyper that give the CPU load in %. We voluntary choose the clipart vumeter18.emf that has a transparent background. We set two rules, the first set the background as red if the value is upper 80 % the second paint the background in green by default.

The visual result is done below for a 5 % load.

If the SNMP value if of counter type (always increasing up to the maximum value and wrapping) you should check the Counter type check box within the Dynamic Aspect tab.

Example of SNMP counter

Object Name          : [ ipforwdatagrams ]
Children of Object   : [ ip ]
From MIB Description : [ RFC1213-MIB ]
Registered in File   : [ Rfc1213.mib ] The File is loaded
---------------------------------------------------------------
SYNTAX : [9] Counter,(Counter)
ACCESS : READONLY
STATUS : MANDATORY
---------------------------------------------------------------
OID LEN (8) : 1.3.6.1.2.1.4.6.
iso(1).org(3).dod(6).internet(1).mgmt(2).mib-2(1).ip(4).ipforwdatagrams(6)
---------------------------------------------------------------
DESCRIPTION :
"The number of input datagrams for which this
entity was not their final IP destination, as a
result of which an attempt was made to find a
route to forward them to that final destination.
In entities which do not act as IP Gateways, this
counter will include only those packets which were
Source-Routed via this entity, and the Source-
Route option processing was successful."

The Counter Type is checked. LoriotPro calculates the difference between each polling interval and display the value.

The following Vu-meter informs you that 170 IP datagram have been forwarded by the router during the last 15 seconds.
