WCF is a general communication framework and the more you use it, the more knobs you find there are to tune (endpoint, security, serialization, etc). I have an application that is sensitive to a number of QoS attributes and I’d like to begin tweaking the settings to understand how each impacts bandwidth, latency and scalability of this WCF-based application.
As far as I can see, there is no general entry point to collect the following metrics, but I’m hoping we can come up with a list of technique for gathering them:
- Number of calls
- Round trip time of call
- Bandwidth utilization
- Serialized size of requests and responses
FWIW, I don’t mind capturing these metrics as long as there are reasonable entry points where I can insert hooks (even if this means diving into specific implementation – e.g. DuplexChannel).
WCF has a ton of performance counters available – from your performance monitor in Windows, you should be able to select a wide range of counters to see how things are going.
You can measure a ton of things, like number of concurrent calls, duration of those calls, and a lot more. Tap into it – it’s almost endless in its capabilities! 🙂
See this WCF Performance Counters page on MSDN for details.
See how to enable and also monitor perf counters in WCF here or here.
