In FastNetMon we have complete support for Prometheus based monitoring. It can be enabled this way (please do not use 0.0.0.0 for production setups and use private ranges for security reasons):
sudo fcli set main prometheus enable sudo fcli set main prometheus_host 0.0.0.0 sudo fcli set main prometheus_port 9209 sudo fcli commit
After that, you will be able to access metrics via standard Prometheus interface from http://127.0.0.1:9209/metrics
FastNetMon exports following types of metrics to Prometheus endpoint:
- Total traffic for IPv4 and IPv6
- Per network traffic (enabled by default but can be disabled)
- Per host traffic for IPv4 and IPv6 (disabled by default).
To enable per network metrics you need to apply following configuration changes:
sudo fcli set main prometheus_export_network_ipv4_counters true sudo fcli set main prometheus_export_network_ipv6_counters true sudo fcli commit
To enable per host metrics you need to apply following configuration changes:
sudo fcli set main prometheus_export_host_ipv4_counters true sudo fcli set main prometheus_export_host_ipv6_counters true sudo fcli commit
FastNetMon exports all metrics which available using sudo fcli show system_counters command. Example:

These values can be used to create alerts and monitor that FastNetMon works correctly.
General alerts:
- traffic_db_errors must not exceed 0, it will mean that FastNetMon is having issues with sending flows to traffic_db
- speed_recalculation_time_seconds must not exceed 0. If it does it will mean that FastNetMon cannot recalculate traffic in reasonable time (<1 second) and it will lead to significant traffic calculation inaccuracy
- influxdb_writes_failed must not exceed 0, it will mean that FastNetMon is having issues with sending metrics to InfluxDB
- clickhouse_metrics_writes_failed must not exceed 0, it will mean that FastNetMon is having issues with sending metrics to Clickhouse
sFlow mode:
- sflow_raw_packet_headers_total_speed this value must not be zero. It counts number of sFlow samples processed per second. It confirms that plugins is enabled and receives traffic from routers.
- sflow_bad_packets and sflow_bad_flow_samples should be both be zero as they will mean some serious issues with sFlow protocol encoding.
Netflow / IPFIX mode:
- netflow_all_protocols_total_flows_speed this value must not be zero. It counts number of Netflow / IPFIX flows processed by second. It confirms that plugins is enabled and receives traffic from routers.
- netflow_v9_too_large_field, ipfix_too_large_field should not exceed 0, it means that device uses unusal length for some field and it may cause issues with traffic accounting
- netflow_v9_broken_packets should be both be zero as they will mean some serious issues with Netflow v9 protocol encoding.
- netflow_ipfix_udp_packet_drops should be 0, it means that receiving UDP socket is dropping traffic due to performance issues.
