Today, `stackdriver_exporter` allows specifying `--monitoring.metrics-type-prefixes`. And, some prefixes include multiple subsystems. For example, `logging.googleapis.com/log_entry_count` exports metrics for the following subsystems among others: `gae_app`, `cloud_function`, `gce_instance`, `gke_container`, `k_8_s_cluster`. It would be...
This change is a prototype that would add user parameters to NDT7 measurements and archival results. The current implementation is not ready to merge in its current form. This is...
Today, a data analyst must check the server port and infer that port 443 means WSS and port 80 means WS. This may not be universally true. The server knows...
@mattmathis reported that it's possible to set the max pacing rate for a socket using `setsockopt`. This could be done at the same time [BBR is enabled ](https://github.com/m-lab/ndt-server/blob/master/bbr/bbr_linux.go#L19). This could...
As part of investigation by @mattmathis to find a method for instrumenting ndt with application metrics we found that some ping/pong rtt metrics are being generated but not collected during...
We've received several user reports of different performance from ndt5 vs ndt7 that could be a sign of something more widespread. Case 1: * User reported leasing a symmetric 100Mbps...
Once the sender errors are differentiated from clean shutdowns, https://github.com/m-lab/ndt-server/issues/312 the probable errors remaining should be part of the ndt7 archive schema. This is helpful for data analysis.
During our initial client migrations to ndt7, we found that under some conditions (unknown), clients may run for up to 11s (maybe more, but the client stopped at 11s) and...
@gfr10598 reported that gardener was observing about ~100k zero length files / day. I spot checked a random ndt pod and found a number of zero-length files. Filtering _only_ the...
