From Target Navigation Icon Exadata Storage Server Grid
Monitor “Extreme Flash” Configuration
1. Target Navigation Icon
2. Perf. Section for Flash Read & Write
3. Note only Flash Disk Size
4. Monitor Flash IO service time
Tip:
• OLTP’s peak load only consumes 20% of flash throughput
• Use excess throughput for scans!
• Using flash increases scan throughput by up to 5x!

Lessons from Oracle Public Cloud
Enterprise Manager used to monitor entire public cloud
infrastructure
Largest Monitored Site
• Over 2.5 Million Targets
• 51 Exadata, 11k Databases, 150K WLS servers, 900K SOA Composites, 1350 Business Applications, 5k Beacons, 24k Agents
• 3.4 million events processed per day
Leverage groups for everything
• Group of group hierarchies aligned with how they manage targets. Largest group: over 200k targets
• Use System Dashboard to monitor top level groups
• Provides summary counts of target down, critical and warning incidents for each top level group
Set Lifecycle Status for the most important targets
• Guarantees rapid delivery of notifications & creation of incidents/tickets for the most important events
Tight control over metrics & thresholds
• Disable unused metrics
• Put meaningful thresholds on metrics they care about
• Create incidents on important events.
• Use templates to deploy metric settings.
Blackouts at group level, control who sets the blackouts
Over 2.5M targets & 3.4 Million Events per Day
