PMCollect gathers Sensor Control statistics for the following performance metrics:
- Flowmeter
- BW Regulator
- DMM (Delay Measurement Message)
- SLM (Synthetic Loss Measurement)
- PL (Packet Loss)
Data is collected from remote devices as follows:
- Flowmeter and BW Regulator applications: Data is retrieved from the device/FPGA every second.
- vSOAM applications: Data is generated based on received CFM frames.
The STATSD agent collects data from each application and sends it to a server connected to the Sensor Control/Legacy Orchestrator. The data from Sensor Control to the Legacy Orchestrator is sent via compressed binary files. Legacy Orchestrator then generates CSV files and sends them to a remote server and/or Provider Connectivity Assurance.
- Legacy Orchestrator handles CSV file generation in PMCollect, while Sensor Control handles CSV file generation for History Buckets.
- Legacy Orchestrator automatically re-enables the streaming state of PMCollect on devices it manages, even if a user has disabled it via the Sensor Control CLI (e.g.
pmcollect edit configuration state enable streaming-state disable).
Configuration
PMCollect configuration can be done in Sensor Control using CLI commands only (i.e. pmcollect edit, pmcollect show). Web-based configuration is not supported. For information, see: Assurance Sensor Control CLI Guide
All configurations, including those available in Sensor Control, can be performed using Legacy Orchestrator. For information, see: Metrics Collection
