njmon（nimon） + influxdb2 + grafana 系统性能监控

可能是采用influxdb2原因，grafana官方找的几个仪表盘都不能呈现数据，自己随便做了几个。一次点击：Load Data, API Tokens， my-user's Token。1. 本指令用于测试 -s 设置为 1 ，实际情况应当适当放款以降低监工负载。2. 实际监控环境应考虑结合cron保证 nimon进程存活状态。配置influxdb地址（采用docker容器名）启动nimon监控

influxdb

docker run --name influxdb -d -p 8086:8086 \
    -e DOCKER_INFLUXDB_INIT_MODE=setup \
    -e DOCKER_INFLUXDB_INIT_USERNAME=my-user \
    -e DOCKER_INFLUXDB_INIT_PASSWORD=my-password \
    -e DOCKER_INFLUXDB_INIT_ORG=my-org \
    -e DOCKER_INFLUXDB_INIT_BUCKET=my-bucket \
    influxdb:2.4.0

获取token

一次点击：Load Data, API Tokens， my-user's Token

点击复制到剪贴板

grafana

docker run -d --name=grafana -p 3000:3000 --link influxdb grafana/grafana:9.1.2

默认账号密码 admin admin

配置数据源

选择InfluxDB

Query Language选择Flux

配置influxdb地址（采用docker容器名）

配置数据库详细信息

点击保存并测试

nimon

下载地址：https://master.dl.sourceforge.net/project/nmon/nmeasure_linux_v80beta2_influxdb2.zip?viasf=1

解压编译

unzip nmeasure_linux_v80beta2_influxdb2.zip
gcc njmon_linux_v80.c -o nimon -D OSNAME=\"Deepin\" -D OSVERSION=\"20\" -D HW=\"unknown\" -O4

注意：生成可执行程序必须命名nimon，方便启动nimon模式。

启动nimon监控并向influxdb2写入数据

sudo ./nimon -s 1 -i 127.0.0.1 -p 8086 -x "my-bucket" -y "my-user" -O "my-org" -T "LSeFOfZnz704NUEhI3EUeogLDsIPn5IjqAxBOfJgCTBckoaxk48qQrUuxw6AlGXwrrf7Y9f2-LZiL9rWS6tQZQ=="

注意：

1. 本指令用于测试 -s 设置为 1 ，实际情况应当适当放款以降低监工负载

2. 实际监控环境应考虑结合cron保证 nimon进程存活状态。

配置监控仪表盘

可能是采用influxdb2原因，grafana官方找的几个仪表盘都不能呈现数据，自己随便做了几个
