普通安裝和docker安裝process-exporter對linux進程進行監控

普通安裝部署process-exporter

wget https://github.com/ncabatoff/process-exporter/releases/download/v0.4.0/process-exporter-0.4.0.linux-amd64.tar.gz

tar -xvf process-exporter-0.4.0.linux-amd64.tar.gz

進入到解壓目錄下編寫配置文件

vim process-exporter-ncabatoff.yaml

process_names:

  - name: "{{.Matches}}"

    cmdline:

    - 'redis-server'

  - name: "{{.Matches}}"

    cmdline:

    - 'mysqld'

  - name: "{{.Matches}}"

    cmdline:

    - 'org.apache.zookeeper.server.quorum.QuorumPeerMain'

  - name: "{{.Matches}}"

    cmdline:

    - 'org.apache.hadoop.mapreduce.v2.hs.JobHistoryServer'

  - name: "{{.Matches}}"

    cmdline:

    - 'org.apache.hadoop.hdfs.qjournal.server.JournalNode'

注 cmdline:  所選進程的唯一標識，ps -ef 可以查詢到。如果改進程不存在，則不會有該進程的數據採集到。

 

 

 

 

編寫啓動腳本

vim /usr/lib/systemd/system/process_exporter.service  （必須在這個目錄下面）

 

 

[Unit]

Description=Prometheus exporter for processors metrics, written in Go with pluggable metric collectors.

Documentation=https://github.com/ncabatoff/process-exporter

After=network.target

 

[Service]

Type=simple

User=prometheus

WorkingDirectory=/opt/process-exporter-0.4.0.linux-amd64

ExecStart=/opt/process-exporter-0.4.0.linux-amd64/process-exporter -config.path=/opt/process-exporter-0.4.0.linux-amd64/process-exporter-ncabatoff.yaml

Restart=on-failure

[Install]

WantedBy=multi-user.target

 

 

 

加載啓動process_exporter服務

systemctl daemon-reload

systemctl start process_exporter

systemctl enable process_exporter

 

 

docker方式安裝部署

拉取鏡像 docker pull feisky/process-exporter

 

新建目錄 mkdir /opt/process-exporter-0.4.0.linux-amd64/config

 

進入到目錄中

創建編輯配置文件process-exporter.yml

 

process_names:

  - name: "{{.Comm}}"

    cmdline:

    - '.+'

 

 

 

執行運行容器命令（注意：最後的/config/process-exporter.yml的路徑是新建目錄process-exporter-0.4.0.linux-amd64下的相對路徑）

docker run -itd -p 9256:9256 --restart="always" --privileged -v /proc:/host/proc -v /opt/process-exporter-0.4.0.linux-amd64/config:/config feisky/process-exporter --procfs /host/proc -config.path /config/process-exporter.yml
