This update for netdata fixes the following issues:

Update to 1.31.0 (go.d.plugin 0.29.0)

The v1.31.0 release of Netdata comes with re-packaged and
redesigned elements of the dashboard to help you focus on your
metrics, even more Linux kernel insights via eBPF, on-node machine
learning to help you find anomalies, and much more.
This release contains 10 new collectors, 54 improvements (7 in the
dashboard), 31 documentation updates, and 29 bug fixes.
At a glance
We re-packaged and redesigned portions of the dashboard to improve
the overall experience. Part of this effort is better handling of
dashboard code during installation—anyone using third-party
packages (such as the Netdata Homebrew formula) will start seeing
new features and the new designs starting today. The timeframe
picker has moved to the top panel, and just to its right are two
counters with live CRITICAL and WARNING alarm statuses for your
node. Click on either of these two open the alarms modal.
We've also pushed a number of powerful new collectors, including
directory cache monitoring via eBPF. By monitoring directory cache,
developers and SREs alike can find opportunities to optimize memory
usage and reduce disk-intensive operations.
Our new Z-scores and changefinder collectors use machine learning
to let you know, at a glance, when key metrics start to behave
oddly. We'd love to get feedback on these sophisticated, subjective
new brand of collectors!
