Anton Tolchanov	c153e6ae2f	prober: migrate to Prometheus metric library This provides an example of using native Prometheus metrics with tsweb. Prober library seems to be the only user of PrometheusVar, so I am removing support for it in tsweb.

Anton Tolchanov	50d211d1a4	cmd/derpprobe: allow running all probes at the same time This allows disabling spread mode, which is helpful if you are manually running derpprobe in `--once` mode against a small number of DERP machines.

Anton Tolchanov	100d8e909e	cmd/derpprobe: migrate to the prober framework `prober.DERP` was created in #5988 based on derpprobe. Having used it instead of derpprobe for a few months, I think we have enough confidence that it works and can now migrate derpprobe to use the prober framework and get rid of code duplication. A few notable changes in behaviour: - results of STUN probes over IPv4 and IPv6 are now reported separately; - TLS probing now includes OCSP verification; - probe names in the output have changed; - ability to send Slack notification from the prober has been removed. Instead, the prober now exports metrics in Expvar (/debug/vars) and Prometheus (/debug/varz) formats.

Will Norris	71029cea2d	all: update copyright and license headers This updates all source files to use a new standard header for copyright and license declaration. Notably, copyright no longer includes a date, and we now use the standard SPDX-License-Identifier header. This commit was done almost entirely mechanically with perl, and then some minimal manual fixes. Updates #6865 Signed-off-by: Will Norris <will@tailscale.com>	2 years ago

Denton Gentry	d8953bf2ba	cmd/derpprobe: don't alert for smaller failures. There is a Cosmic Background level of DERP Unreachability, with individual nodes or regions becoming unreachable briefly and returning a short time later. This is due to hosting provider outages or just the Internet sloshing about. Returning a 500 error pages a human. Being awoken at 3am for a transient error is annoying. For relatively small levels of badness don't page a human, just post to Slack. If the outage impacts a significant fraction of the DERP fleet, then page a human.
