IT-Control Chart against Network Traffic Data vs. Process Level Data Chart


The 1st implementation of applying SEDS methodology against network trafic data was published at my CMG'07 presentation (SYSTEM  MANAGEMENT  BY  EXCEPTION:

Process level data chart could also be used together with the control charts to find which particular process is responsible for some unusual spikes.

The full back-up caused one big spike per week expanding activity to work hours, which could be dangerous to interfere with other DB2 on-line workload on that server.
