As an alternative to InfluxDB you could store traffic metrics in ClickHouse. I suggest using this guide to setup Clickhouse
Please upgrade to FastNetMon 2.0.65 before starting this guide. We made number of changes in CH export.
Enable metrics export to Clickhouse:
sudo fcli set main clickhouse_metrics enable sudo fcli commit
In deep cooperation with community we offer following dashboards:
- Top 10 hosts by load link
- Per network traffic link
- Total traffic link
- Traffic for specified host link
- Traffic for specified network link
Also, you could use such query in clickhouse-client tool to retrieve data:
select host, packets_incoming from fastnetmon.host_metrics where metricDate == today() AND metricDateTime >= now() - 5 order by packets_incoming desc limit 10;
Clickhouse does not have capability to remove old data automatically, you can use our script for this task.
