Query: Characterizing and Mitigating Anti-patterns of Alerts in Industrial
  Cloud Systems   Alerts are crucial for requesting prompt human intervention upon cloud
anomalies. The quality of alerts significantly affects the cloud reliability
and the cloud provider's business revenue. In practice, we observe on-call
engineers being hindered from quickly locating and fixing faulty cloud services
because of the vast existence of misleading, non-informative, non-actionable
alerts. We call the ineffectiveness of alerts "anti-patterns of alerts". To
better understand the anti-patterns of alerts and provide actionable measures
to mitigate anti-patterns, in this paper, we conduct the first empirical study
on the practices of mitigating anti-patterns of alerts in an industrial cloud
system. We study the alert strategies and the alert processing procedure at
Huawei Cloud, a leading cloud provider. Our study combines the quantitative
analysis of millions of alerts in two years and a survey with eighteen
experienced engineers. As a result, we summarized four individual anti-patterns
and two collective anti-patterns of alerts. We also summarize four current
reactions to mitigate the anti-patterns of alerts, and the general preventative
guidelines for the configuration of alert strategy. Lastly, we propose to
explore the automatic evaluation of the Quality of Alerts (QoA), including the
indicativeness, precision, and handleability of alerts, as a future research
direction that assists in the automatic detection of alerts' anti-patterns. The
findings of our study are valuable for optimizing cloud monitoring systems and
improving the reliability of cloud services.
