What is an "Element"?

I am in the process of sizing my network to determine which version of Orion I need and am wondering whether an element refers to a single device or a single port on a device. For example... does a 24 port switch count as 1 element or 24 elements? Please help. Thank you in advance for your kind assistance.

Licensing of Orion NPM is based upon the highest of one the following three values:

Total number of managed network interfaces - including switch ports physical interfaces virtual interfaces sub-interfaces VLANS etc.
Total number of managed nodes - including routers switches servers access points modems etc.
Total number of managed volumes (logical disks).

Just because you have a 24port switch, does not mean you should/will monitor all 24 interfaces.
Here are the stats from my installation:

Network Elements 2845 Elements <<< Total.
- Nodes 591 Nodes
- Interfaces 2161 Interfaces <<< license based on this number, since it is the largest of the 3
- Volumes 93 Volumes

Most likely your license will be based on the number of interfaces you are monitoring.

Your switch actually counts as 25 elements...one device, 24 interfaces.

An element is any separate, monitorable entity. Devices are elements, as are interfaces and volumes. The licensing scheme seems to limit your maximum number of elements to the highest element type.

For example, if you could monitor 250 single devices with one interface and one volume apice. This would be monitoring 750 elements overall, but only a max of 250 of one type.

If I understand it correctly both will count, there are three different pools that counts and each one can reach the license limit before everything is 'full'. I think the counters was volumes, interfaces and nodes.

Another example. We are currently licensed for the SL250.

Network Elements 287 Elements
Nodes 46 Nodes
Interfaces 227 Interfaces
Volumes 14 Volumes

As you can see, if we add another 23 interfaces, I'll hit our limit and will need to upgrade to the SL500.

I have a followup question to this.

I am trying to price out Orion NPM, Netflow and APM, per the online quote I think our enviroment will need the SL2000, but there doesnt seem to be a SL2000 for APM. do the licenses have to match? Or could I get a SL2000 for NPM, then a SL100 for Netflow(only about 15 routers in our env), then a AP250 for applicaitons?

If not and they have to line up then how do i get a SL2000 for APM? (one isnt listed)

thanks

Keep in mind that this thread is from 2004. That is a long long time and many versions ago. Many things have changed.

An element is a network interface, a node, or a volume. An SL2000 means you can have 2000 of each. For most people, the interfaces will be the largest number. NTA is matched to your NPM license to reflect the size of your network.

APM is *not* tied to your NPM size. It's based on the number of component monitors you need. A component is like a process, a Windows Service, a file monitor, a script, etc.

Right 2004, gotcha.

Thanks for the information gorilla.

Denny, you said something here that conflicts with an understanding I have always had about SW licensing. You said that "An SL2000 means you can have 2000 of each".

I have always understood that an SL2000 allowed you to monitor 2000 of any one of the three element types and up to 1999 of the other two for a total of as many as 5998 monitored elements on an SL2000 license.

Is that not correct?
