Loom with a View (Beta)
This is an experimental, auto-generated dashboard of the dataplane of the FABRIC testbed.
Data and graphs for this dashboard are generated using Patchwork,
which is invoked every few days across the whole of FABRIC to gather a snapshot of its network activity.
See our paper on Patchwork if you'd like to find out how the whole process works.
See the top-level dashboard that shows historical data.
Beta release: Please send feedback and data/visualization requests to Nik Sultana. You're also welcome to get in touch to contribute code or other improvements. All the code that generated this data (and this page) is open source.
Follow-up Note
(Follow-up Notes are manually added to the dashboard to explain some aspect of this Patchwork run that stood out to us.)We confirmed that the Patchwork problem observed on 19 Sept has been fixed. We observed some persistent problems on specific FABRIC sites, and two additional unusual issues, and these are being investigated further with upstream help.
On that day, Patchwork ran continuously for a 12-hour window, during which time:
- FABRIC Sites sampled:
30
Note: Sites are sampled simultaneously, in parallel. We don't provide site-specific details, and even site names are anonymized on this dashboard. - Sampling outcome by Site:
succeeded=60.00%,
failed=36.67%,
degraded=0.00%,
inprogress=3.33%
Note: "failed" means that FABlib raised an unrecognized exception during slice submission or that a site didn't have any smart NICs available at the time; "degraded" means that fewer resources than Patchwork sought were available; and "inprogress" means that the sampling did not complete on time — usually that's a sign of a site that happens to be very busy at the time. - Size of data sample (compressed):
12G
Note: To generate the graphs below, the data is aggressively reduced to lower the load on our computing resources since this analysis is run every few days. All sites with more than 1GB data (uncompressed) are removed from the analysis, and only 1/100 of the remaining data files are analyzed.
Distribution of frame sizes in FABRIC's dataplane:
This graph shows a histogram of frame sizes. This distribution can hint at the type of workloads that were crossing the network at the time the sample was collected.
Frequently-occurring protocol headers on FABRIC:
This graph shows a histogram of the most frequently-occurring protocols that were found in the analyzed sample. This graph complements the previous graph by telling us more about the workloads that were crossing the network at the time the sample was collected.
Variety of application/protocol headers across FABRIC site ports: (anonymised)
For different (physical) network ports that are sampled (across different FABRIC sites), this graph shows the variety of different protocols/applications that were observed during the time the sample was collected.
