Hi! I’m a doctor at GroundWork and I’m here to cure your IT monitoring ailments. Let’s take a closer look at the four deadly
diseases that are rapidly slowing down IT Operations.
Checkitosis SlippedDisc(overy)
Cloudfluenza Monitoropia
These four culprits could be behind the slow performance of your IT environment.
Diagnosis
Data interpretation takes too long due to too many service checks that clog information
Strained monitoring performance
Dashboards are not intuitively obvious
Vaccination
Selectively add new checks
Investigate the motives of anyone who advocates large number of checks
Treatment
Reduce the number of checks - get to the distill essence of the problem
Rank checks from top to bottom & trim low value checks
CheckitosisToo many service checks
Massive network degradation
Monitoring solution performs unthrottled discovery on all devices and available metrics
Not scalable on a larger network
Follow up automatic discovery by thoughtful culling
Follow top down approach to monitoring
Configure dependencies to suppress spurious and derived alarms
No real cure – like smoking, don’t start
Regularly review checks and remove the worthless ones
Reconsider your baseline number of checks to start from top five instead of narrowing a large list.
Diagnosis Vaccination Treatment
Slipped Disc(overy)Unthrottled Network Scanning
CloudfluenzaInability to perform
Performance and availability issues in cloud or virtualized environment
Supplement Cloud monitoring with general purpose tools
Check performance measurements before making changes (to neighbors)
Make incremental changes; measure (retrofit risk mitigation)
Identify non-Cloud contributors to performance issues (network, storage, shared resources)
Use more than adequate hardware
Better CPU shares to allocate CPU requests better
Diagnosis Vaccination Treatment
Obsessive hyper focus on tools and configuration without attention to process improvements
Keep a run book of what to do when a failure type is experience
Improve and update the run book regularly
Create escalation process
Top down approach - figure out the why, what & how of monitoring
Stop only when all the problems are solved; enlist expertise as needed
MonitoropiaObsessive focus ontools and configuration
Diagnosis Vaccination Treatment
The GroundWork Hospital wishes you a fast, healthy and happy network!
