Administration Challenges

• 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

When problems arise, what is the root cause?

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 processor

Toll -as ArcGIS Server instances

Cars -as map requests

System Test

• Individually test services that we expect to receive high traffic to define a service

throughput baseline given a certain min/max instance configuration

• Investigate/analyze performance for services that have been alerting as slow or non-

responsive in Big Brother

• Develop test extents/parameter files to be exported using custom python scripts so

that they can be configured in long running system wide load tests performed by

the SA’s using JMeter

mxdperfstat

• Been around for a while and still very useful

• Easy to batch script

• All service sponsor provided map documents were tested using mxdperfstat to

identify cases where poor configuration could impact server performance

mxdperfstat

• 1.59 seconds may not seem horrible but this service is

expected to see very heavy traffic and accounts for 6

instances on 8 servers.

• Improvements to the cartography could make a noticeable

difference in overall server performance and/or free resources

for other services
