    2525The OpenGENI rack is implemented on Dell hardware, here is the [wiki:GENIRacksHome/OpenGENIRacks/DellPartsList parts list].

     27=== Q. How can I tell if experiments are running in my OpenGENI rack? ===
     28On the control node you can check the list of experiments that are currently active by issuing an !OpenStack command
     29as follows:
     30{{{
     31$ source /etc/novarc
     32$ $ keystone tenant-list|egrep slice
     33| 8f38b505cbef4c4a82463f250d3f9ad6 |    ch.geni.net:ln-test+slice+OG-EXP-1    |   True  |
     34| cc16776ac7b44341a2430546c2907684 | ch.geni.net:ln-test+slice+gr-clem-ig-gpo |   True  |
     35| 559624c7d7b043aeb3a3128bb393e9d3 |    ch.geni.net:ln-test+slice+lnexp23     |   True  |
     36}}}
     37The list returned shows that there are 3 experiments that have active resource allocations.

     39=== Q. Are there OpenGENI logs? ===
     40The OpenGENI rack runs GENI Rack Aggregate Manager (GRAM) software to manage rack compute and network resources. There are 4 gram processes to provide these functions and
     41their logs are:
     42  - /var/log/upstart/gram-am.log - The aggregate manager logs which AM API requests and the quantum commands used to allocate the requested resources.
     43  - /var/log/upstart/gram-ctrl.log - The !OpenFlow Controller running on the OpenGENI rack which will capture request for OF resources.
     44  - /var/log/upstart/gram-opsmon.log - Monitoring log is created by the gram-mon daemon, file captures relevant information from the GRAM snapshots which are logged in this file easier readability.
     45  - /var/log/upstart/gram-vmoc.log - VLAN-based Multiplexing !OpenFlow Controller (VMOC) is a switch to experimenter provided controller, that multiples based on VLAN tag and switch DPID/port. A default Layer2 Learing controller is used for slices that do not specify a controller.
