一、采集器安装

1. Categraf简介

Categraf 需要部署到所有需要监控的机器上，因为采集 CPU、内存、进程等指标需要读取操作系统里的信息。
Categraf 推送监控数据到服务端，基于 Prometheus 的 RemoteWrite 协议。

categraf插件说明
categraf部署文档
categraf下载地址
下载文件例如： categraf-v0.3.45-linux-amd64.tar.gz

2. Categraf部署

有些监控插件，docker部署方式很难配置，所以采用二进制部署Categraf。

1. 删除不使用的插件
   categraf-v0.3.45-linux-amd64/conf/input.*
2. 修改插件配置*.toml
3. 修改Categraf配置config.toml

[global]
hostname = "机器标签"
[[writers]]
url = "http://192.168.6.226:17000/prometheus/v1/write"
[ibex]
enable = true
servers = ["192.168.6.226:20090"]
[heartbeat]
url = "http://192.168.6.226:17000/v1/n9e/heartbeat"

4. 拷贝categraf
   拷贝categraf-v0.3.45-linux-amd64内的所有文件/文件夹到要部署的环境 /home/monitor/categraf
5. 安装启动categraf

cd /home/monitor/categraf && chmod +x categraf && ./categraf --install && ./categraf --start

• 其他命令

# 以service方式安装, 相当于添加service文件+systemctl daemon-reload
sudo ./categraf  --install
# 以service方式卸载, 相当于systemctl stop categraf + 删除service文件
# 如果安装过categraf，先卸载
sudo ./categraf  --remove
# 以service方式启动categraf ，相当于systemctl start categraf
sudo ./categraf  --start
# 以service方式停止categraf，相当于systemctl stop categraf
sudo ./categraf  --stop
# 以service方式查看categraf，相当于systemctl status categraf
sudo ./categraf  --status
# 采集了哪些 mysql 指标
sudo ./categraf --test --inputs mysql

3. 测试服务器部署

4. 系统监控插件

disable_connection_stats = truetcp_ext = false
ip_ext = false

• ntp时间 插件：监控机器时间偏移量
  input.ntp/ntp.toml

# 采集频率
interval = 15# ntp 服务器
ntp_servers = ["ntp.aliyun.com"]# 响应超时时间
timeout = 5

• 进程 插件：采集进程 running 的有多少，sleeping 的有多少，total 有多少
  input.processes/processes.toml，可使用默认配置

# 采集频率
interval = 15#  强制使用ps命令收集 
# force_ps = false#  强制使用/proc收集
# force_proc = false

• system 插件：采集系统负载信息
  input.system/system.toml，可使用默认配置

# 采集频率
interval = 15# 是否收集system_n_users信息
# collect_user_number = false

5. 显卡监控插件

• nvidia显卡 插件：监控nvidia显卡信息
  input.nvidia_smi/nvidia_smi.toml

# 采集频率
interval = 15# 执行本地命令
nvidia_smi_command = "nvidia-smi"# 可以通过运行`nvidia-smi --help-query-gpus`来查找可能的字段
# `AUTO` 自动检测要查询的字段
query_field_names = "AUTO"

6. 服务监控插件

• docker 插件：docker容器监控
  input.docker/docker.toml

# 采集频率
interval = 15[[instances]]
# interval = global.interval * interval_times
interval_times = 1## Docker Endpoint
endpoint = "unix:///var/run/docker.sock"# 包括/排除的容器
container_name_include = []
container_name_exclude = []gather_services = false
gather_extend_memstats = falsecontainer_id_label_enable = true
container_id_label_short_style = falsetimeout = "5s"perdevice_include = []total_include = ["cpu", "blkio", "network"]docker_label_include = []
docker_label_exclude = ["annotation*", "io.kubernetes*", "*description*", "*maintainer*", "*hash", "*author*", "*org_*", "*date*", "*url*", "*docker_compose*"]

• 日志 插件：提取日志内容，转换为监控metrics
  input.mtail/mtail.toml

# 采集频率
interval = 15[[instances]]
progs = "/home/monitor/categraf/conf/input.mtail/prog1" # 日志解析规则配置文件的路径
