Semaphore statistics
Semaphore statistics
Plugin: windows.plugin Module: PerflibObjects
Overview
Inter-Process Communication (IPC) enables different processes to communicate and coordinate with each other. This collector monitors IPC semaphores, which are synchronization tools that:
- Control access to shared resources (like files, memory, or devices).
- Ensure only one process can access a resource at a time.
- Prevent conflicts between competing processes.
It queries for the ‘Objects’ object from Perflib in order to gather the metrics.
This collector is only supported on the following platforms:
- windows
This collector only supports collecting metrics from a single instance of this integration.
Default Behavior
Auto-Detection
The collector automatically detects all of the metrics, no further configuration is required.
Limits

Performance Impact
The default configuration for this integration is not expected to impose a significant performance impact on the system.
Setup
Prerequisites
No action required.
