EG-MON-4: Infrastructure Device Performance Test

This page captures status for the test case EG-MON-4, which verifies that the rack head node performs well enough to run all the services it needs to run while OpenFlow and non-OpenFlow experiments are running. For overall status see the ExoGENI Acceptance Test Status page.

Test Plan Steps

This test cases sets up several experiments to generate resource usage for both compute and network resources in an InstaGENI Rack. The rack used is the GPO rack and the following experiments are set up before head node device performance is reviewed:

  • EG-MON-4-exp1: EG GPO non-OpenFlow experiment with 10 VM nodes, all nodes exchanging traffic.
  • EG-MON-4-exp2: EG GPO non-OpenFlow experiment with 1 VM and one bare metal node, both exchanging traffic.
  • EG-MON-4-exp3: EG GPO OpenFlow experiment with 2 nodes in rack exchanging traffic with 2 site GPO OpenFlow campus resources.
  • EG-MON-4-exp4: EG GPO OpenFlow experiment with 2 nodes exchanging traffic with 2 remote EG RENCI OpenFlow nodes.

The setup of the experiments above is not captured in this test case, but the RSpec are available [insert_link_here]. Also traffic levels and types will be captured when this test is run.

1. View OpenFlow control monitoring at GMOC and verify that no monitoring data is missing

Before starting any experiments that request compute or network resources, collected information for baseline performance for the GPO rack head node at https://bbn-hn.exogeni.net/rack_bbn/check_mk/. Here are performance measurements for the node:

Checked Round Trip Averages:

Checked CPU Utilization:

Checked CPU Load:

Checked Memory Used:

At the time of these measurements, three foam slivers were in place and 57 FlowVisor rule entries:

   [lnevers@bbn-hn ~]$ foamctl geni:list-slivers --passwd-file=/opt/foam/etc/foampasswd|grep sliver_urn
   "sliver_urn": "urn:publicid:IDN+pgeni.gpolab.bbn.com+slice+jbs15:013f6aa7-e600-4be5-9e31-5c0436223dfd", 
   "sliver_urn": "urn:publicid:IDN+pgeni.gpolab.bbn.com+slice+jbs16:8aad0aae-ae92-4a3c-bd5e-43f7456f628e",

   [lnevers@bbn-hn ~]$ /opt/flowvisor/bin/fvctl --passwd-file=/opt/flowvisor/etc/flowvisor/fvpasswd listFlowSpace |grep rule |wc -l 
     57    

Also according to list resources there are 43 VM available via GPO SM:

      <node component_id="urn:publicid:IDN+exogeni.net:bbnvmsite+node+orca-vm-cloud" 
       component_manager_id="urn:publicid:IDN+exogeni.net:bbnvmsite+authority+am" 
       component_name="orca-vm-cloud" exclusive="false">
            <hardware_type name="orca-vm-cloud">
                  <ns3:node_type type_slots="43"/>
            </hardware_type>

and 25 VMs available via the ExoSM and 1 Bare Metal:

      <node component_id="urn:publicid:IDN+exogeni.net:bbnvmsite+node+orca-vm-cloud" 
      component_manager_id="urn:publicid:IDN+exogeni.net:bbnvmsite+authority+am" 
      component_name="orca-vm-cloud" exclusive="false">
            <hardware_type name="orca-vm-cloud">
                  <ns3:node_type type_slots="25"/>
            </hardware_type>
            <available now="true"/>

      <node component_id="urn:publicid:IDN+exogeni.net:bbnvmsite+node+orca-xcat-cloud" component_manager_id="urn:publicid:IDN+exogeni.net:bbnvmsite+authority+am" component_name="orca-xcat-cloud" exclusive="false">
            <hardware_type name="orca-xcat-cloud">
                  <ns3:node_type type_slots="1"/>
            </hardware_type>

Set up the first experiment EG-MON-4-exp1 at the GPO SM. Experiment included 10 VM nodes exchanging traffic, without OpenFlow. Verified all nodes in the sliver were ready, and started a ping on each of the ten nodes to another node in the sliver using 64 bytes packets with an interval of 3 packet/sec. After 20 minutes, checked statistics for:

Checked CPU Utilization:

Checked CPU Load:

Check Memory:

Left previous experiment running and set up the second experiment EG-MON-4-exp2 at the ExoSM for the GPO site. Experiment included 1 bare metal and 1 VM, without OpenFlow. Verified all nodes in the sliver were ready, and started continuous Iperf traffic between the two nodes:

2. View VLAN 1750 data plane monitoring

Verify the VLAN 1750 data plane monitoring which pings the rack's interface on VLAN 1750, and verify that packets are not being dropped

3. Verify that the CPU idle percentage on the head node is nonzero

Misc scenarios

The following statistics were collected while NUM_of_EXP(*) experiments were in place:
