Hello community :)

While testing FastNetMon community edition and following the installation instructions for both the community fastnetmon and the associated vistual stack, I have some trouble having the predefined grafana dashboards return some output.

They all returns errors like this:

Received exception from server (version 25.1.4):
Code: 60. DB::Exception: Received from localhost:9000. DB::Exception: Unknown table expression identifier 'fastnetmon.network_24_metrics_ipv4' in scope SELECT toStartOfInterval(toDateTime(metricDateTime), toIntervalSecond(2)) AS time, network, avg(bits_incoming) AS Bandwidth FROM fastnetmon.network_24_metrics_ipv4 WHERE (metricDateTime >= toDateTime(1739635416)) AND (metricDateTime <= toDateTime(1739639016)) AND ((metricDateTime >= toDateTime(1739635416)) AND (metricDateTime <= toDateTime(1739639016))) AND (network = '') GROUP BY network, time ORDER BY time ASC. (UNKNOWN_TABLE)

It looks like it is querying clickhouse for unexistant tables.

Here are the tables created by fastnetmon community edition:

fastnetmon :) show tables;

SHOW TABLES

Query id: 3ddd2f10-61ca-46be-8d59-1963f3542b9d

   ┌─name─────────────────┐
1. │ host_metrics         │
2. │ host_metrics_ipv6    │
3. │ network_metrics      │
4. │ network_metrics_ipv6 │
5. │ system_metrics       │
6. │ total_metrics        │
7. │ total_metrics_ipv4   │
8. │ total_metrics_ipv6   │
   └──────────────────────┘

It looks like there are a lot of missing tables if I compare to what the dashboards are trying to query.

Have I missed a step or configuration option ?

Kind regrads!

Hello!

Thank you for sharing your issue.

This table is available only in our commercial offering FastNetMon Advanced. Community edition has no option to populate per-24 networks 

Sincerely yours, Pavel Odintsov

Hello Pavel!

Thank you for your quick reply. 

Oh okay, I see. It seems there are "only" two of the installed dashboards that can be used with the community edition then.

- Total Traffic Clickhouse official
- Traffic for specific host

These seems to be working with CE, all the others are returning an error with missing tables.
At first, I thought I had misconfigured something. 

Thanks for the info and for FastNetMon :)

Kind regards
