Add node resource hourly/daily aggregation tables#220
Open
Conversation
Add host spec external model and 9 transformation models for aggregating observoor node resource data into hourly and daily granularities: - fct_node_host_spec: Hardware specs from observoor host_specs - fct_node_cpu_utilization_hourly/daily: CPU usage aggregated per node - fct_node_memory_usage_hourly/daily: Memory usage aggregated per node - fct_node_disk_io_hourly/daily: Disk I/O aggregated per node and r/w - fct_node_network_io_hourly/daily: Network I/O per node, port, direction Hourly models aggregate slot-level per-process data from existing fct_node_*_by_process tables. Daily models re-aggregate from hourly using weighted averages (by slot_count).
