Fault localization, a core element in network fault management, is the process of inferring
the exact failure in a network from the set of observed symptoms. Since faults in network …

In cloud-native applications, a large fraction of operational failures, known as outages, result
in violations of Service Level Objectives (SLOs). SLOs are defined around specific …

A method of identifying at least one resource in a distributed computing system which is a
potential root cause of performance degradation of the system includes the steps of …

Clustered enterprise middleware systems employing dynamic workload scheduling are
susceptible to a variety of application malfunctions that can manifest themselves in a …

Self-managing systems require continuous monitoring to ensure correct operation. Detailed
monitoring is often too costly to use in production. An alternative is adaptive monitoring …

This dissertation presents an adaptive probing based tool for fault diagnosis in computer
networks by addressing the problems of probe station selection and probe selection. We first …

Component level performance thresholds are widely used as a basic means for
performance management. As the complexity of managed applications increases, manual …

(57) ABSTRACT A method of identifying at least one resource in a distributed computing
system which is a potential root cause of perfor mance degradation of the system includes …

A correctly functioning enterprise-software system exhibits long-term, stable correlations
between many of its monitoring metrics. Some of these correlations no longer hold when …

Black-box instrumentation can support problem diagnosis in distributed systems without the
need to modify the application code or to understand its semantics. We explore a novel, low …
