Track Service Reuse Metrics

December 24, 2011

Service driven systematic reuse takes conscious design decisions, governance, and disciplined execution – project after project. In order to sustain long running efforts such as service orientation, it is critical to track, report, and get buy-in from senior management in the organization. So what metrics are useful? Here are a few:

Total number of service operations reused in a time period
Total effort saved due to systematic reuse in a time period
Number of new service consumers in a time period
Number of new consumer integrations in a time period (this includes integrations from both new and existing consumer
Service integrations across transports/interface points (for instance, the service operation could be accessed SOAP over HTTP, or as SOAP over JMS, or REST, etc.)

What metrics do your teams track?

Capture Service Metrics

October 22, 2010

Metrics are very useful to understand service usage, volume trends (growth/decline) – leading to improving performance/capacity planning, diversity of user base, etc.

A service mediation layer can initialize and persist metrics and can help efforts to mine that data to generate reports using the data. What specific metrics can be captured? Here are a few attributes:

incoming time, outgoing time (or publication time) , transport (whether service was invoked via HTTP, JMS, or some other transport), requesting host name/queue name etc. Additionally, if a request processing resulted in an error – error details including stack trace can be captured. Finally, service/operation-specific metrics can be captured – if you don’t have demanding reporting requirements, these attributes can be stored as a set of name/value pairs.

In a follow up post, will elaborate on how specific metrics can be captured throughout service processing.
