Definitions
Performance
• Speed, e.g. response time (seconds)
Scalability
• The ability to increase output and maintain acceptable performance
Capacity
• The maximum level of output the system can produce, e.g.• X cars/sec• X maps/sec
At capacity Over capacity
Bottleneck
• Resource(s) limiting the performance or capacity
Not bottleneck bottleneckThink of :Lanes -as CPU processorToll -as ArcGIS Server instancesCars -as map requests
Capacity
Throughput(req/hr)
CPU Utilization (%)
Memory used (Mb)
Network used (Mbps)
Content length (bytes)

Infrastructure Capacity Planning
Provide sufficient hardware resources
GIS Systems are bound by:1. CPU - typically2. Memory – when large number of services3. Disk – Image Service, Synchronization4. Network – low bandwidth deployment5. Poorly configured virtualization can result in 30% or higher performance degradation
Most systems are CPU bound
Most well-configured and tuned GIS systems are CPU bound.
InfrastructureMemory requirements
Wide ranges of memory consumptions

System Monitoring
Monitoring Enterprise GISChallenges
• Multiple administrators • Multiple disparate monitoring/diagnostic tools• Data collected in a reactive fashion: on demand and for limited time• Correlation of data with different timestamp is difficult• ArcGIS administrators do not have access to all tools, data and reports• Challenging to quickly identify the root cause and take appropriate measures
• Many excellent monitoring tools on the market• Few provide GIS dashboards• System Monitor can be used as reference implementation
Standards for effective GIS monitoring
Enterprise GIS effective monitoring“PIECE” of mind with System Monitor
• Proactive• Integrated
- Dashboards across all tiers
• End-to-End- All tier monitoring
• Continuous- %Coverage provided
• Extendable- Custom queries
