Data mining

Back to the clustering tutorial, remember that we’ve found something strange happening on day 2019-11-28 on ack for host_id=51c390afac2f78e0d48c370a991bb94e, 0da342d5cd1c9a1f720113ad49bc6426, 9bea1ec113b48a23edbf2e264c4f6aac

Let’s first graph all ack measures in the correct date range (remember we’re not in 2019 anymore)

and then drill down to those clustered host_id. something funny isn’t it. This high peak of acknowledgement requests !!
