# Intel Baseband Accelerator Input Plugin
|
||
|
|
|
||
|
|
This plugin collects metrics from both dedicated and integrated Intel devices
|
||
|
|
providing Wireless Baseband hardware acceleration. These devices play a key role
|
||
|
|
in accelerating 5G and 4G Virtualized Radio Access Networks (vRAN) workloads,
|
||
|
|
increasing the overall compute capacity of commercial, off-the-shelf platforms
|
||
|
|
by integrating e.g.
|
||
|
|
|
||
|
|
- Forward Error Correction (FEC) processing,
|
||
|
|
- 4G Turbo FEC processing,
|
||
|
|
- 5G Low Density Parity Check (LDPC)
|
||
|
|
- Fast Fourier Transform (FFT) block providing DFT/iDFT processing offload for
|
||
|
|
the 5G Sounding Reference Signal (SRS)
|
||
|
|
|
||

## Global configuration options <!-- @/docs/includes/plugin_config.md -->
|
||
|
|
|
||
|
|
In addition to the plugin-specific configuration settings, plugins support
|
||
|
|
additional global and plugin configuration settings. These settings are used to
|
||
|
|
modify metrics, tags, and field or create aliases and configure ordering, etc.
|
||
|
|
See the [CONFIGURATION.md][CONFIGURATION.md] for more details.

## Configuration
|
||
|
|
|
||
|
|
```toml @sample.conf
|
||
|
|
# Intel Baseband Accelerator Input Plugin collects metrics from both dedicated and integrated
|
||
|
|
# Intel devices that provide Wireless Baseband hardware acceleration.
|
||
|
|
# This plugin ONLY supports Linux.

|
|
## Path to socket exposed by pf-bb-config for CLI interaction (mandatory).
|
||
|
|
## In version v23.03 of pf-bb-config the path is created according to the schema:
|
||
|
|
## "/tmp/pf_bb_config.0000\:<b>\:<d>.<f>.sock" where 0000\:<b>\:<d>.<f> is the PCI device ID.
|
||
|
|
socket_path = ""
|
||
|
|
|
||
|
|
## Path to log file exposed by pf-bb-config with telemetry to read (mandatory).
|
||
|
|
## In version v23.03 of pf-bb-config the path is created according to the schema:
|
||
|
|
## "/var/log/pf_bb_cfg_0000\:<b>\:<d>.<f>.log" where 0000\:<b>\:<d>.<f> is the PCI device ID.
|
||
|
|
log_file_path = ""
|
||
|
|
|
||
|
|
## Specifies plugin behavior regarding unreachable socket (which might not have been initialized yet).
|
||
|
|
## Available choices:
|
||
|
|
## - error: Telegraf will return an error on startup if socket is unreachable
|
||
|
|
## - ignore: Telegraf will ignore error regarding unreachable socket on both startup and gather
|
||
|
|
# unreachable_socket_behavior = "error"
|
||
|
|
|
||
|
|
## Duration that defines how long the connected socket client will wait for
|
||
|
|
## a response before terminating connection.
|
||
|
|
## Since it's local socket access to a fast packet processing application, the timeout should
|
||
|
|
## be sufficient for most users.
|
||
|
|
## Setting the value to 0 disables the timeout (not recommended).
|
||
|
|
# socket_access_timeout = "1s"
|
||
|
|
|
||
|
|
## Duration that defines maximum time plugin will wait for pf-bb-config to write telemetry to the log file.
|
||
|
|
## Timeout may differ depending on the environment.
|
||
|
|
## Must be equal or larger than 50ms.
|
||
|
|
# wait_for_telemetry_timeout = "1s"
|
||
|
|
```
|
||
|
|
|
||
|
|
## Metrics
|
||
|
|
|
||
|

|
||
|
|
subset of following measurements may be exposed:
