Managing Networks Today:
Network Management Megatrends 2014 Research Highlights
Finding: No Single “Source of Truth”
Which types of data are the most common, and which are most valuable for network availability and
performance monitoring? Our research findings, shown in Figure 2, indicate that there is no one
single data source to satisfy the needs. Further, there is great diversity in approaches. Only log data
achieved a majority use level, and then only barely so. Further, the size of the managed network had
a strong influence on preferences. For example, while log files are highly relevant across networks of
all sizes, management system APIs are most preferred for managing very large networks. Also, smaller
networks tend to require less data diversity. EMA recommends network management strategies that
take advantage of as many data sources as possible to ensure completeness of visibility and effective
issue recognition.
