What is Stacking?

The stacking feature that was implemented into version 1.2.1 which allows the user to combine datasets into a single graph is known as stacking.

For example, if you have 3 IPSLA latency tests:

  1. Latency test from Customer in South Africa to NNI point
  2. Latency test from NNI point to NNI point
  3. Latency test from NNI point to Customer in Kenya

Those 2 tests measure the latency individually but if you ware interested in seeing the end-to-end latency you can stack those individual graphs into a single graph.

The same will work for any data set in Iris, from stacking multiple CPUs on servers to QoS policy maps.

How to configure Stacking

Each stack is generated manually based on the type of stack and the number of mnemonics you want to stack. 

These are the steps to configure stacking:

Step 1: On the Iris portal, click on Configuration -> Views -> Edit Stacks

Step 2: You will be presented with a list of configured stacks. You can either edit the exsisting stacks or create a new one by clicking on the “+” in the top right hand corner.

Step 3: Clicking on the “+” gives you the Create a new Stack modal. Start by giving the stack a name. This name will be the mnemonic and a searching item in Iris.

Step 4: Choose the type of stack from the drop-down list.

Step 5: Select the menu option Stacks. In this case it will be IPSLA stacks. Choose the type of data.

Step 6: Auto complete the device name the test is configured on; then auto complete the tag or test name and click Add. Once all the tests you wish to stack have been added, click Save.

Now that the stack has been created, you are able to search for the stack name in Iris to display the graph of the stack. It can also be added to reports and assigned to views.
