About
Confirm to KISS principle.
Linux system base monitor metrics collector.
Linux 系统基础监控项采集实现。
Usage
go get -u github.com/OpenCCTV/sys_base
For more detail, see main.go.
Network bandwidth
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
