Performance data collection models
The performance metrics to be collected are supplied from the Technology Packs and stored in time series database for further processing and visualization.
- SNMP resource and metric polling
Network polling is a process to collect information from devices and to monitor their behavior. A technique that continually interrogates a peripheral device to see whether it has data to transfer. You can collect the metrics from different SNMP-enabled devices and entity types based on the data in the Management Information Base (MIB) variables of the devices.
- File-based resource and metric collection
The File Collector is configured to collect metrics from the discovered resources based on the installed Technology Packs. The File Collector Service parses the files that are generated from the EMS and converts the files into a common Avro record format. These records contain inventory and metric data. The File Collector sorts the windowed data and sends the inventory data to the Resource management and metric data to the Timeseries Service for further processing and storage.
