    2020This section will guide you through creating and starting a slice, requesting a LAMP services certificate for you slice, uploading your experiment's topology to [http://groups.geni.net/geni/wiki/LAMP/Glossary#UNIS UNIS], and setting up the instrumentation and measurement facilities of your slice. The expected time required to setup your slice with the LAMP I&M System is around 10 minutes. Following this guide through the end is aimed to take about 30 minutes. Let us know how long it takes you and places for improvement!

     22=== Before we start: a few words on the LAMP I&M System design ===

    2424It is useful to understand the general principles behind the steps we will take throughout this tutorial. The LAMP I&M System is built on top of three pillars:

     101=== 2. Create and start our slice ===
     102
     103After modifying the RSpec as explained on the previous step, we proceed to create the slice/sliver as usual. Please refer to the [http://www.protogeni.net/trac/protogeni/wiki/Tutorial ProtoGENI tutorial] if you're not familiar with the following commands.

     128
     129You can see the full manifest returned for this particular instance [http://groups.geni.net/geni/attachment/wiki/LAMP/Tutorial/lamptutorial-manifest.xml here]. Save (copy/paste) this manifest to a file, we will call it lamptutorial-manifest.xml.
     130
     131At this point it is important to notice the valid_until field of the manifest: valid_until="2010-09-22T03:34:50". If you feel like this is not enough time for your slice, use the renewsliver.py test script to extend your slice. You should do this now as step 4 depends on this (actually, it depends on the expiration time of the slice, which seems to be a couple of hours more than what's in the manifest). While our slice is being started we can go ahead and setup the LAMP infrastructure for our experiment.
     132
     133=== 3. Upload your experiment's topology to UNIS ===
     134
     135UNIS is the glue that holds the LAMP I&M System together (see the '''Before we start''' section above). Services are configured (and configure themselves) through the topology data and the directory of services in UNIS. The first step we need to take before being able to configure and utilize our LAMP services is to convert our experiment's manifest into the UNIS topology schema and send it to UNIS. This is done automatically by the script lamp-sendmanifest.py. The usage for the lamp-sendmanifest.py script is as follows.
     136
     137{{{
     138$ test/lamp-sendmanifest.py
     139Not enough arguments
     140Usage: <manifest> <slice_urn> [credential]
     141}}}
     142
     143Where `<manifest>` is the file we saved our manifest to; `<slice_urn>` is the fully-qualified URN of our slice (''urn:publicid:IDN+emulab.net+slice+lamptutorial''); and [credential] is a file with our credential for the slice. The credential parameter is optional if you use the LAMP certificate for your slice (see step 4). We could have done step 4 first and used the LAMP certificate for this step, but we want to show that UNIS can be accessed with your own certificate and the slice credential. So we will go ahead and get our slice credential first:
     144
     145{{{
     146$ test/getslicecredential.py -n lamptutorial > lamptutorial-credential.xml
     147}}}
     148
     149A small modification needs to be done for now on the credential we just saved: remove the first line that indicates the xml version and encoding. Make sure you do not modify any other line, otherwise the signature check will fail. Our [http://groups.geni.net/geni/attachment/wiki/LAMP/Tutorial/lamptutorial-credential.xml credential] is now ready to be used with the lamp-sendmanifest.py script.
