GENI Monitoring Resource Check

This procedure outlines how to check the status and get statistics for a slice which has resources at multiple aggregates. It is assumed that the operator following this procedure has a login for the GENI Monitoring web interface. if you do not have an account see the instructions for Getting an Account page.

For an overview of the GENI Monitoring Web interface features see the GENI Monitoring Overview page.

Access Slice information

Slice information can be accessed in different ways in the GENI Monitoring web interface, all are highlighted here:

  1. From the Dashboard:
  • If you know the slice name, simply select the Slices item in the Dashboard and type the slice name in the upper-right hand Search box and then click on the slice name. This will update the bottom of the main panel to include a Map , Members and Slivers for the slice name selected.
  • If you are looking for the slices that belong to a specific user, select the Users item in Dashboard and type the user name in the upper-right hand Search box and then click on the username. This will update the bottom of the main panel to include all Slivers and Slices for the username selected.
  1. From the Navigation Panel":

  • If you want the GENI Monitoring information for a slice, in the left-side navigation select GENI Objects->Slices (same as selecting Dashboard).
  • If you want the Data Store information reported for a slice, in the left-side navigation select GENI Stores->Aggregates->Aggregate_Name. This will update the bottom of the main panel to show available information. For example selecting the aggregate al2s.internet2.edu will show Switches, Links and Slivers being reported by that network aggregate. In the Slivers panel you can type in the slice name to narrow down the results to the slice of interest.
  • If you want to know the GENI Clearinghouse information for a slice, in the left-side navigation select GENI Stores->OPSConfig Stores->geni-prod. This will update the bottom of the main panel to show Aggregates, Authorities, and Check Stores. Select the Authorities panel and then click on ch.geni.net. This will provide you with the Clearinghouse view of Users and Slices

Mapping Slices to Slivers and VLANs

This sections show how to get all sliver information associated with a slice. Currently only AL2S will report slice information. To show this procedure a slice named triangle is being used, the slice includes a compute resource at each of 3 aggregates (uchicago-ig, nysernet-ig, and cenic-ig) which are connected as a triangle topology.

From the Dashboard click on the Slices item and search for triangle. The search will result in the slice ID ch.geni.net_ln-test_slice_triangle being shown. The slice id ch.geni.net_ln-test_slice_triangle uses the format Clearinghouse_GENIProject_slice_Slicename, therefore we can tell that ch.geni.net_ln-test_slice_triangle is a slice from the GENI Clearinghouse (ch.geni.net), in the project ln-test and is named triangle.

Click on the slice ID, this will update the bottom of the main panel to include all Members and Slivers for the slice triangle. Select the Sliver panel and click on the sliver ID, which is made up of the slice URN plus a unique identifier (urn:publicid:IDN+ch.geni.net:ln-test+slice+triangle:1bc9e85e-146c-4991-a4e9-96c5f3a5dee9). This results in Links information being shown for the sliver as reported by AL2S:

We will select each of the links to show the endpoint associated with the link. For example when selected, the link I2-LOSA-NEWY32AOA-VLAN-51145 will show these end-points:

Selecting the first endpoint sdn-sw.losa.net.internet2.edu:eth5/1:1550 will show the Bytes Metrics Report:

Selecting the other endpoint sdn-sw.newy32aoa.net.internet2.edu:eth7/2:1714 will show Bytes Metrics Report:

Repeat for all endpoints associated with the two remaining links (I2-LOSA-STAR-VLAN-51146 and I2-NEWY32AOA-STAR-VLAN-51144). All links have similar traffic levels.

Mapping Slices to Interfaces

To map a Slice to an interface, you should follow the procedure described in the previous section and when the endpoint is selected, you can choose the interface link:

and then see the overall interface traffic details:

The resulting interface page also includes an Endpoints panel that lists all endpoint that are active on the interface.

Mapping a VLAN to Aggregates

If you want to know how a VLAN is used in the network, select the GENI Hardware->VLAN in the navigation and enter the VLAN ID in the upper-right hand Search box. In this example, we are looking for information for VLAN 3733:

The IDs returned are:

  • al2s.internet2.edu_interface_sdn-sw.newy32aoa.net.internet2.edu:eth15%2F6:rutgers-ig:3733 - the AL2S information for this VLAN, which shows that the VLAN is in use at "rutgers-ig" which is connected via the New York router "newy32aoa" to AL2S.
  • instageni.rutgers.edu_interface_pc3:eth1:3733 - The compute resources information that shows that the VLAN is connected to a compute resources on pc3 (a xen server).
  • instageni.rutgers.edu_interface_procurve2:1:19:3733 - The rack switch(procurve2) that is using VLAN 3733.
