IG’s context
• We offer Spread Betting and CFD trading
• Trading and price updates are time critical – Every millisecond counts
• Using AppDyanmics in production for 4 months
LONDON APPDYNAMICS USER GROUP | FEBRUARY 2013 | 5
Development process
Proactive than reactive approach to performance:• Identifying latency issues in production is too late• Mostly on trading and charting platform
We try to improve the performance on each release

Development Process
Thinking about monitoring from the start• Influences how we design• It was expensive and focused
Ð Ad-hoc classes to wrap specific transactions and log metrics.Ð Creating custom metric collectors and graphing them.
• Not possible to have it everywhere
LONDON APPDYNAMICS USER GROUP | FEBRUARY 2013 | 7
Development Process
Leave metric collection to its experts and focus on our business domain and differentiators.

Architecture

Architecture
LONDON APPDYNAMICS USER GROUP | FEBRUARY 2013 | 10
QA
• Link Business Transactions to Services• Simpler option to sign-off architectural changes• Provide snapshots on bug reports when a service returns an error.
LONDON APPDYNAMICS USER GROUP | FEBRUARY 2013 | 11
QA
• Helps with regression: Business transaction health view easily tells us: Ð What transactions are fundamentally brokenÐ Can’t tell if all transactions are OK
LONDON APPDYNAMICS USER GROUP | FEBRUARY 2013 | 12
Operations & Support
Lower the bar to find performance issues• Easier to collaborate with other teams to solve the problem:
Ð focus on the solution.Ð With DBAs - > DB call times
• can pin point performance bottlenecks:Ð Bottlenecks caused by downstream componentsÐ Inefficient code in unfamiliar parts of the platformÐ Thread hogging calling a SAAS provider
• troubleshooting integration with 3rd party software.Ð Messaging broker

Operations & Support
• BTs enables us to correlate exceptions across nodes
LONDON APPDYNAMICS USER GROUP | FEBRUARY 2013 | 14
Operations & Support
Ability to correlate events (cluster, nodes, etc).[gc , cpu]
LONDON APPDYNAMICS USER GROUP | FEBRUARY 2013 | 15
Operations & Support
Reduce the number of false positives alerts (Correlation of metrics for alerting).
LONDON APPDYNAMICS USER GROUP | FEBRUARY 2013 | 16
Operations & Support
Inventory of JVMs and config (* run reports on jvms)
LONDON APPDYNAMICS USER GROUP | FEBRUARY 2013 | 17
Operational successes
• Datacenter failover
• Already used to improve our throughput
LONDON APPDYNAMICS USER GROUP | FEBRUARY 2013 | 18
Operational challenges
• No way to promote config changes through environments
• Changes to BTs or metric names invalidates dashboards
• Invest in training to get the most out of it
• To get best of the tool work with Appd engineers
LONDON APPDYNAMICS USER GROUP | FEBRUARY 2013 | 19
Going forward
• Doing end user monitoring (web and mobile)• Collect real-time business metrics and KPIs• Use events to mark application version changes• Diff flowmaps• Compare platform performance across all nodes between load tests
