v12 v13 52 52 == Largest Traffic Source at an Aggregate == 53 53 54 This scenario shows how to determine the slice that is generating the largest traffic amount at a site. This example assumes the site that is being investigated is Clemson.54 This scenario shows how to determine the slice that is generating the largest traffic amount at a site. This example assumes the site that is being investigated is the Chicago InstaGENI site. 55 55 56 56 1. In `Dashboard` click on the `Aggregates` button, this will display all known aggregates. 57 57 58 2. Narrow down the list by typing "c lemson" in the upper-right `Search` field, which will show only Clemson aggregates. As you can see from the Nodes and Slivers counts, the InstaGENI rack has the most activity and most likely the source of the issue. So will we focus on clemson-ig:58 2. Narrow down the list by typing "chicago" in the upper-right `Search` field, which will show only Chicago aggregates. As you can see from the Nodes and Slivers counts, the InstaGENI rack has the most activity and most likely the source of the issue. So will we focus on uchicago-ig: 59 59 60 [[Image(c lemson-aggregates.jpg)]]60 [[Image(chicago-aggregates.jpg)]] 61 61 62 62 3. We will use GENI reporting to find the VLAN that is the source of most traffic. Select `GENI Reporting`-> `Reports`. 63 4. On the resulting page select the "Report Type" `VLAN Network Throughput [By Aggregate] from the pull-down and in the "Report Target" type start typing "c lemson", the field will automatically list all aggregate names that match, select "clemson-ig".63 4. On the resulting page select the "Report Type" `VLAN Network Throughput [By Aggregate] from the pull-down and in the "Report Target" type start typing "chicago", the field will automatically list all aggregate names that match, select "uchicago-ig". 64 64 65 5. In the `Reports List` results section, choose the report named "VLAN Network Throughput for Aggregate [clemson-ig]". The report will show VLAN usage for the aggregate form highest to lowest. Pick the highest usage VLAN ID. In this procedure we will choose VLAN 1234)65 5. In the `Reports List` results section, choose the Report Type named "VLAN Network Throughput [By Aggregate]", select the Report Target `uchicago-ig`, and the Report Range "Today". The resulting report "VLAN Network Throughput for Aggregate [uchicago-ig]" will show VLAN usage for the aggregate form highest to lowest for each VM Server Host interface in use. Following are the VLAN statistics report for one of the VM Servers: 66 66 67 6. Go to `Dashboard` and click on the `Aggregates` button, this shows list of all known VLANs. Narrow down the list by typing "1234" in the upper-right `Search` field. Results will now include AL2S and Clemson monitored VLANs. 67 [[Image(chicago-vlan.jpg)]] 68 68 69 6. Select "instageni.clemson.edu_interface_pc3:eth2:1234" and you will get data metrics for the VLAN 1234 at Clemson IG.69 6. We are going to pick the highest usage VLAN ID on the VM Server PC2 using VLAN 3076): 70 70 71 7. Go back to the list of VLAN Metric available and this time choose the AL2S entry "sdn-sw.atla.net.internet2.edu:eth5/2:1234" to view statistics reported from the AL2S switch in Atlanta where Clemson is connected to AL2S Network. 71 [[Image(chicago-vlan2.jpg)]] 72 73 7. Go to `Dashboard` and click on the `VLANs` button, this shows list of all known VLANs. Narrow down the list by typing "3076" in the upper-right `Search` field. Results will now include AL2S and Chicago IG monitored VLANs. 74 75 [[Image(chicago-vlan-3076.jpg)]] 76 77 6. Select "sdn-sw.star.net.internet2.edu:eth7/1:3076" and you will get AL2S link details: 78 79 [[Image(al2s-3076.jpg)]] 80 81 7. Select the link "I2-NEWY32AOA-STAR-VLAN-51144" to find the endpoints to the link and the name of the sliver (and slice) that owns the VLAN. 82 72 83 73 84 == Resources allocated by an Experimenter ==
