Subject Re: Anomaly detection
Date Tue, 20 Mar 2018 13:23:02 GMT
Hello Salvatore,

I used SPM Sematext that had this feature already 3 or 4 years ago I
believe. SPM offers some out of the box dashboards for Cassandra. See
https://sematext.com/spm/

More recently we built some templates for Cassandra in Data Dog that I
believe should show the most important metrics and hopefully in a
usable/efficient way for alerting and troubleshooting. If this is of
interest, check https://www.datadoghq.com/blog/tlp-cassandra-dashboards/.
Datadog provides anomaly detection for a while too:
https://www.datadoghq.com/blog/introducing-anomaly-detection-datadog/.

If you choose Datadog, adding anomaly detection to the overview dashboard
charts is probably a good starting point.

The tools mentioned above are commercial solutions. I am not sure about
which open source stacks could provide this feature.

That being said, looking from time to time to the dashboards (at least) and
setting alerts using the standard 'thresholds' was often enough. I did not
make real use of anomaly detections, even though there are probably
interesting things that can be done on alerting with this feature.

Hope that helps,

C*heers,
