网卡流量统计

注意：多张网卡接口需要用 tags 分类。

Grafana 配图用 order by ts asc，平时调试 SQL 用 order by ts desc。例：

TimescaleDB SQL

select date_trunc('minute', "ts") as time, metric, sum(value) from datapoints where metric='net.in.bytes' and tags->>'face'='enp0s3' group by ts, metric order by ts asc;

Clickhouse SQL

SELECT
    $timeSeries as t,
    value as `net.in.bytes`
FROM $table
WHERE
    $timeFilter
    and endpoint= '$endpoint'
    and metric = 'net.in.bytes'	
    and visitParamExtractString(tags, 'face') = '$iface'
ORDER BY t
