It is a mechanism which allows processes to communicate with each -other and synchronize their actions. - -This collector exposes information about: - -- Message Queues: This allows messages to be exchanged between processes. It's a more flexible method that - allows messages to be placed onto a queue and read at a later time. - -- Shared Memory: This method allows for the fastest form of IPC because processes can exchange data by - reading/writing into shared memory segments. - -- Semaphores: They are used to synchronize the operations performed by independent processes. So, if multiple - processes are trying to access a single shared resource, semaphores can ensure that only one process - accesses the resource at a given time. - - - - -This collector is supported on all platforms. - -This collector only supports collecting metrics from a single instance of this integration. - - -### Default Behavior - -#### Auto-Detection - -This integration doesn't support auto-detection. - -#### Limits - -The default configuration for this integration does not impose any limits on data collection. - -#### Performance Impact - -The default configuration for this integration is not expected to impose a significant performance impact on the system. - - -## Metrics - -Metrics grouped by *scope*. - -The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels. - - - -### Per Inter Process Communication instance - - - -This scope has no labels. - -Metrics: - -| Metric | Dimensions | Unit | -|:------|:----------|:----| -| system.ipc_semaphores | semaphores | semaphores | -| system.ipc_semaphore_arrays | arrays | arrays | -| system.message_queue_message | a dimension per queue | messages | -| system.message_queue_bytes | a dimension per queue | bytes | -| system.shared_memory_segments | segments | segments | -| system.shared_memory_bytes | bytes | bytes | - - - -## Alerts - - -The following alerts are available: - -| Alert name | On metric | Description | -|:------------|:----------|:------------| -| [ semaphores_used ](https://github.com/netdata/netdata/blob/master/health/health.d/ipc.conf) | system.ipc_semaphores | IPC semaphore utilization | -| [ semaphore_arrays_used ](https://github.com/netdata/netdata/blob/master/health/health.d/ipc.conf) | system.ipc_semaphore_arrays | IPC semaphore arrays utilization | - - -## Setup - -### Prerequisites - -No action required. - -### Configuration - -#### File - -There is no configuration file. -#### Options - - - -There are no configuration options. - -#### Examples -There are no configuration examples. - - |
