Feature/Performance Counter
From SambaWiki
Overview
Samba's new Performance Counter infrastructure provides PDU based statistics for the Samba file server. Each incoming SMB creates a call to the generalized perfcount framework, from which a backend module can track PDU type, size, latency, and user.
Two backend modules are currently implemented.
Components
Component | Description | Developer | Status |
---|---|---|---|
SMBD Infrastructure | Implement a dispatch table API which different backends can plug into. | tstecher | Completed |
perfcount_onefs.so | A module specific to the OneFS operating system which makes syscalls storing aggregate SMB performance measurements in kernel memory. These statistics are later retrieved via a command line tool. | tstecher | Completed |
perfcount_test.so | A simple module which writes packet data out to the samba.log file every 50 operations. | tstecher | Completed |
Future Development
- Implement a more generic Unix backend which logs to a database.
- Integrate with Holger's SMB Traffic Analyzer backend and CLI tools.
- Remove deprecated START_PROFILE()/END_PROFILE() subsystem
