Information Gathering -> Monitoring: Simple system metrics
Risk and Opportunity
Risk: Without simple metrics analysis of incidents are hard. In case an application uses a lot of CPU from time to time, it is hard for a developer to find out the source with linux commands.
Opportunity: Gathering of system metrics helps to identify incidents and specially bottlenecks like in CPU usage, memory usage and hard disk usage.
Usefullness: Very High
Required knowledge: Low (one discipline)
Required time: Low
Required resources (systems): Low
Implementation hints: collectd
