GIMI I&M Tools: Basic Experimenter Use Case

For discussion on 053012:

1) Establish test/experiment environment

2) Obtain slice of GENI resources, install and configure GIMI I&M tools and reference/actual experiment

3) Run and orchestrate GIMI I&M tools and reference/actual experiment

4) Observe I&M measurement results on GIMI presentation service inside of the slice

5) Push I&M measurement results to iRODS archive service

6) Pull I&M measurement results from iRODS archive service to IREEL portal service, then analyze/process/present results, and push back to iRODS archive service

7) Release experiment resources

1) Establish test/experiment environment

1.1) Establish user workspace service

1.2) Gather necessary keys, certificates and credentials

1.3) Verify availability of desired aggregates

1.4) Verify availability of desired software images/packages

1.5) Verify avaialbility of necessary oeprational services

  • XMPP server
  • IREEL portal service
  • iRODS archive service

2) Obtain slice of GENI resources, install and configure GIMI I&M tools and reference/actual experiment

2.1) Select target aggregates:

  • a) ExoGENI rack VMs, one aggregate
    • MC on VM
    • MPs and ExperApp on VMs (2 or more)

  • b) ExoGENI rack VMs, multiple aggregates (2 or more)
    • MC on VM; each aggregate or one aggregate?
    • MPs and ExperApp on VMs, each aggregate (2 or more)

2.2) Select desired software images/packages:

  • a) VM image including OS plus all GIMI I&M code
    • GIMI I&M code includes both MC and MP code
  • if Gush is used, Gush client can be loaded in image
  • b) Reference/Active Experiment pkg(s)
    • need: experiment topology
      • option: one package to be installed on all nodes
      • option: multiple packages, to be installed on different nodes

2.3) Obtain certs, credentials, passwords and keys

  • required services: GENI CA; GENI SA; GENI key generation service

  • tools: shell scripts (later: clearinghouse portal)

  • at completion: certs, credentials, passwords (to iRODS) and keys in local store, in user workspace

  • typically, do not have to repeat

2.4) Formulate slice topology for test/experiment, and build request rspec

  • tools: how to visualize topology of experiment and I&M tools? use FLUKES?

  • tools: how to build request rspec? edit respec file? use FLUKES?

  • at completion: request rspec in local store, in user workspace

2.5) Acquire resources and load images

  • tools: OMNI, to acquire resources and load images

  • option: also loads software packages for reference/actual experiment

  • at completion: completed slice/slivers of hosts, with images, with VLAN connections

  • at completion: manifest rspec in local store, in user workspace

  • verification: shell scripts that use keys to ssh into hosts; also ping other hosts

  • note: 2.1) through 2.5) parallels rack acceptance tests

2.6) Load software packages for reference/actual experiment (as needed)

  • tools: shell scripts

  • at completion: completed slice/slivers of hosts, with images, with VLAN connections, with all software packages installed

  • verification: shell scripts that ssh into hosts, also ping other hosts; also verify all desired software installed

2.7) Start software processes (as selected)

  • Select options for each node:
    • I&M Measurement Collector (MC), including analysis and presentation (yes or no)
    • I&M Measurement Point (MP) for basic host measurements, e.g., cpu and memory usage (yes or no)
    • I&M Measurement Point (MP) for active network measurements, e.g., ping and iperf (yes or no)
    • Reference/Actual Experiment (yes or no) option: differnet processes on different nodes

  • Typical selections:
    • One node with MC; multiple nodes with MP + Ref/Actual Exper
  • tools: shell scripts or use Gush?

  • at completion: completed slice/slivers of hosts, with images, with VLAN connections, with all software packages installed, with selected software processes running

  • verification: shell scripts that ssh into hosts, ping other hosts, verify all software installed, verify selected processes running or Gush that verifies selected processes running

2.8) Configure selected I&M services

  • objectives:
    • binds services together, e.g., between each MP and the MC
    • configures baseline services
    • verifies that they are ready to run
  • tools: use what tool to assign MPs to interfaces? use what tool to point data from MPs to MC?

  • tools: use what tool to point browser at MC? use what tool to configure presentation service in MC?

  • tools: use what tool (OMF?) to start, stop, reset I&M services; and to observe the transition

  • at completion: configured I&M services, ready to run and collect data

2.9) Configure selected reference/actual experiment services

  • objectives:
    • binds services together to realize overall reference/actual experiment
    • configures baseline services
    • verifies that they are ready to run

  • tools: use what tool to select options in reference/actual experiment? use what tool to bind services together?

  • tools: use what tool (OMF?) to start, stop, reset reference/actual experiment services; and to observe the transition

  • at completion: configured reference/actual experiment services, ready to run and process data, which can be observed by I&M services

3) Run and orchestrate GIMI I&M tools and reference/actual experiment

3.1) Initial setup: start basic host measurement and ping active network measurement I&M services, to verify functionality of I&M services and topology of slice

3.3) Instrument reference/actual experiment: start basic host measurement and ping active network measurement I&M services; then start reference/actual experiment, and gather measurments to verify functionality of refrence/actual experiment in slice

  • at completion: I&M services have collected basic host measurements and ping active network measurements from each MP while reference/actual experiment is running, measured data is in MC, and measured data has been visualized by MAP service; functionality of of refrence/actual experiment in slice has been verified

4) Observe I&M measurement results on GIMI presentation service inside of the slice

  • use GUI on MC to observe measurement results in real time (as noted above)

  • use GUI on MC to observe measurement results after experiment has been completed

  • use what tool to configure presentation of measurment results?

  • can measurement results be keyed to a topology map?

  • use what tool to format group measurement results?

  • use what tool to push measurement results to iRODS archive service?
