Monitoring requirements vs issues?

Plug & play

Easy to implement

Deliver multi-vendor support

Not flexible

Difficult to maintain

Always too many alerts to handle (Christmas tree effect)

Monitoring goals

An easy to manage view, with only actual issues

Straightforward configuration

No false positives

MomciloPolicy to answer all requirement mentioned.How to achieve mentioned goals?

ITAFs approach to good practice monitoring

Tooling

Customized implementation (vs plug & play)

Customized views for users / customers

Customized notifications (sms, mail, IM,)

Everything which can be queried can be monitored

Automated reporting

Customization brings greater integration but requires planningCombining everything in single monitoring to achieve perfection and avoid fragmentation of attention.

ITAFs approach to good practice monitoring

Monitoring operations (event management)

Proactive monitoring (warning / critical)

Acknowledgements Solve the incident (incident management)

Implement an improvement (improvement management)

Fine tune monitoring thresholds

Schedule downtime (change management)

Each level should indicate what approach to takeAcknowledging working in cleanup purposeDowntime to prepare for known issues and changes
