Tip of the day #119 – Windows Communication Foundation Performance Counters

I’ve been working this week on some performance analysis for Windows Communication Foundation and I’d like to share a list of performance counters for WCF.

Basically, the performance counters for WCF are divided into three categories that define the scope of analysis: operation, services and endpoints.

Operation performance counters

These are the performance counters that provide you a good overview about the health of each operation:

  • Calls: Total of calls to the operation;
  • Calls Per Second: Average of calls to the operation per second;
  • Calls Outstanding: Total of calls to the operation still in progress;
  • Calls Failed: Total of calls to the operation that raised unhandled exceptions;
  • Calls Failed Per Second: Average of calls to the operation that raised unhandled exceptions;
  • Calls Faulted: Total of calls to the operation that raised SOAP faults;
  • Calls Faulted Per Second: Average of calls to the operation that raised SOAP faults;
  • Call Duration: Average duration of the calls to the operation;
  • Security Calls Not Authorized: Total of calls that have its execution denied because of authorization issues for the operation;
  • Security Calls Not Authorized Per Second: Average of calls per second that have its execution denied because of authorization issues for the operation;
  • Security Validation and Authentication Failures: Total of authentication failures such as invalid token, missing elements, messages duplicated for the operation;
  • Security Validation and Authentication Failures Per Second: Average of authentication failures per second for the operation;
  • Transactions Flowed: Total of transactions flowed to the operation;
  • Transactions Flowed Per Second: Average of transactions per second flowed to the operation.

Service performance counters

Focused on the service as a whole, the service performance counters give you the number for each service.

  • Calls: Total of calls to the service;
  • Calls Per Second: Average of calls to the service per second;
  • Calls Outstanding: Total of calls to the service still in progress;
  • Calls Failed: Total of calls to the service that raised unhandled exceptions;
  • Calls Failed Per Second: Average of calls to the service that raised unhandled exceptions;
  • Calls Faulted: Total of calls to the service that raised SOAP faults;
  • Calls Faulted Per Second: Average of calls to the service that raised SOAP faults;
  • Call Duration: Average duration of the calls to the service;
  • Instances: Total of service instances;
  • Instances Per Second: Average of service instances per second;
  • Queue Dropped Messages: Total of messages dropped during transport to the service;
  • Queue Dropped Messages Per Second: Average of messages dropped per second during transport to the service;
  • Queued Poison Messages: Total of messages marked as poisoned during transport to the service;
  • Queued Poison Messages Per Second: Average of messages marked as poisoned during transport to the service;
  • Queued Rejected Messages: Total of messages rejected by the queued transport to the service;
  • Queued Rejected Messages Per Second: Average of messages rejected by the queued transport to the service;
  • Reliable Messaging Messages Dropped: Total of reliable messages dropped;
  • Reliable Messaging Messages Dropped Per Second: Average of reliable messages dropped per second;
  • Reliable Messaging Sessions Faulted: Total of reliable messages that have raised faults;
  • Reliable Messaging Sessions Faulted Per Second: Average of reliable messages that have raised faults;
  • Security Calls Not Authorized: Total of calls that have its execution denied because of authorization issues for the service;
  • Security Calls Not Authorized Per Second: Average of calls per second that have its execution denied because of authorization issues for the service;
  • Security Validation and Authentication Failures: Total of authentication failures such as invalid token, missing elements, messages duplicated for the service;
  • Security Validation and Authentication Failures Per Second: Average of authentication failures per second for the service;
  • Transactions Flowed: Total of transactions flowed to the service;
  • Transactions Flowed Per Second: Average of transactions per second flowed to the service ;
  • Transacted Operations Aborted: Total of operations within a transaction that have aborted;
  • Transacted Operations Aborted Per Second: Average of operations within a transaction that have aborted per second;
  • Transacted Operations Committed: Total of operations within a transaction that have committed;
  • Transacted Operations Committed Per Second: Average of operations within a transaction that have committed per second;
  • Transacted Operations In Doubt: Total of operations within a transaction that have an in-doubt response;
  • Transacted Operations In Doubt Per Second: Average of operations within a transaction that have an in-doubt response per second.

Endpoint performance counters

These performance counters provide information specific for an endpoint:

  • Calls: Total of calls to the endpoint;
  • Calls Per Second: Average of calls to the endpoint per second;
  • Calls Outstanding: Total of calls to the endpoint still in progress;
  • Calls Failed: Total of calls to the endpoint that raised unhandled exceptions;
  • Calls Failed Per Second: Average of calls to the endpoint that raised unhandled exceptions;
  • Calls Faulted: Total of calls to the endpoint that raised SOAP faults;
  • Calls Faulted Per Second: Average of calls to the endpoint that raised SOAP faults;
  • Call Duration: Average duration of the calls to the endpoint;
  • Reliable Messaging Messages Dropped: Total of reliable messages dropped;
  • Reliable Messaging Messages Dropped Per Second: Average of reliable messages dropped per second;
  • Reliable Messaging Sessions Faulted: Total of reliable messages that have raised faults;
  • Reliable Messaging Sessions Faulted Per Second: Average of reliable messages that have raised faults;
  • Security Calls Not Authorized: Total of calls that have its execution denied because of authorization issues for the endpoint;
  • Security Calls Not Authorized Per Second: Average of calls per second that have its execution denied because of authorization issues for the endpoint;
  • Security Validation and Authentication Failures: Total of authentication failures such as invalid token, missing elements, messages duplicated for the operation;
  • Security Validation and Authentication Failures Per Second: Average of authentication failures per second for the endpoint;
  • Transactions Flowed: Total of transactions flowed to the endpoint;
  • Transactions Flowed Per Second: Average of transactions per second flowed to the endpoint.
