Add FIREWALL_LOG_TS_RE regex to parse timestamps from firewall log lines, implement firewall_log_seen_at to extract and convert log timestamps to UTC ISO format, add first_seen_at/last_seen_at/observed_at fields to flows in collect_packet_flows (AF_PACKET collector) with timestamp updates on flow aggregation, add timestamp fields to collect_flows (conntrack collector) and parse_firewall_log_line (
Add EBPF_HELPER_CONTRACT.md documenting helper binary invocation with --json/--limit/--duration/--interfaces parameters and expected JSON output format with flows/diagnostics, implement collect_ebpf_flows to invoke helper binary with configurable timeout/window/interfaces and normalize flow fields (source_ip/destination_ip/protocol/ports/packets/bytes/state), add executable_exists and flow_int helpers for binary validation
Reduce agent flow_limit from 2000 to 1500, truncate log_excerpt from 500 to 180 characters in firewall log parsing, increase firewall_log_lines_from_files limit from default to max(limit*2, 1000), add compact_agent_payload to truncate flows array to 50 entries with flow_count/flows_truncated metadata, update agent_heartbeat to store compacted payload instead of full dump, add agentFlowCount helper to
Add RuntimeSettingsRead/RuntimeSettingsUpdate schemas with auto_node_sync_enabled/auto_node_sync_interval_minutes/auto_ipam_sync_enabled/auto_ipam_sync_interval_minutes/last_node_auto_sync_at/last_ipam_auto_sync_at fields, implement firewall_log_lines_from_files to parse /var/log/pve-firewall.log with max_lines limit and error collection, extend collect_firewall_log
Add parse_firewall_log_line to extract SRC/DST/PROTO/SPT/DPT/LEN from kernel log lines with drop/reject/accept decision classification, implement collect_firewall_log_flows to parse journalctl -k output from last 5 minutes with flow aggregation by 5-tuple+decision, add merge_flow_sources to combine packet flows and firewall log flows with deduplication, extend agent config with
Add packet flow collector in agent v0.2.0 using Linux AF_PACKET sockets to capture and aggregate IPv4 TCP/UDP/ICMP flows from VM interfaces (tap/fwln) with configurable window/limit, implement parse_packet_flow to extract 5-tuple from raw Ethernet frames with VLAN tag handling, add selected_flow_interfaces to choose best interface per VM NIC for packet capture, include packet collector
Add interface_traffic collection in agent to aggregate VM/LXC network counters by vmid/nic with tap/fwln/fwpr/fwbr interface ranking, implement collect_interface_traffic to select best interface per VM NIC and format as flow-like records with rx/tx bytes/packets, add collect_flow_diagnostics to capture conntrack binary path and kernel bridge/netfilter settings for debugging, update workload_insights endpoint
Add /agents/ location block to nginx config to proxy agent heartbeat requests directly to backend API without /api/v1 prefix duplication, implement normalized_api_url helper to detect and fix double /api/v1 suffixes in agent config with automatic /api/v1 appending when missing, enhance heartbeat error logging to include HTTP status codes, response body preview, and resolved API URL for debugging connection
Add NodeAgent and TrafficFlow models to track agent status and network flows, implement /agents/heartbeat endpoint to receive interface counters, conntrack flows, firewall status, and nftables ruleset hash from agents, add nexafabric-agent.py Python script to collect host telemetry including VM/LXC interface hints via tap/fwbr regex matching, conntrack flow parsing with protocol/state/byte counters, and pve-firewall status checks,
