前言
skywalking安装完成后,开始我们的第一个监控-监控linux系统。
参考官方文档:
https://skywalking.apache.org/docs/main/next/en/setup/backend/backend-vm-monitoring/
一、下载node_exporter
下载地址:https://prometheus.io/download/#node_exporter
或者:https://github.com/prometheus/node_exporter/tags
我下载的是最新版v1.8.2
二、启动node_exporter
上传压缩包到服务器并解压
执行:
bash
cd /opt/node_exporter/node_exporter-1.8.2.linux-arm64
./node_exporter
执行成功后如图:
浏览器打开:http://10.211.55.120:9100
如图:
三、下载OpenTelemetry Collector
下载地址:https://opentelemetry.io/docs/collector/installation/
或者:https://github.com/open-telemetry/opentelemetry-collector-releases/releases/tag/v0.109.0
我是arm架构cpu,所以下载otelcol_0.109.0_linux_arm64.tar.gz
四、启动OpenTelemetry Collector
4.1 将配置文件下载到同级目录
记得要改其中的两个注意点。
配置文件otel-collector-config.yaml内容如下:
yaml
receivers:
prometheus:
config:
scrape_configs:
- job_name: "vm-monitoring" # make sure to use this in the vm.yaml to filter only VM metrics
scrape_interval: 10s
static_configs:
- targets: ["10.211.55.120:9100"] #注意点1:要改为ip
processors:
batch:
exporters:
otlp:
endpoint: "10.211.55.120:11800" # The OAP Server address #注意点2:要改为ip
# The config format of OTEL version prior to 0.34.0, eg. 0.29.0, should be:
# insecure: true
tls:
insecure: true
#insecure: true
# Exports data to the console
logging:
loglevel: debug
service:
pipelines:
metrics:
receivers: [prometheus]
processors: [batch]
exporters: [otlp, logging]
如图:
4.2 启动
bash
cd /opt/otelcol
./otelcol --config=./otel-collector-config.yaml
启动成功后会一直打印数据。
五、查看
到skywalking网页中,在仪表盘-仪表盘列表-找到Linux-Service,点进去即可看到监控数据:
