-### 使用Categraf基于IPMI工具监控硬件温度、功率、电压
+# IPMI plugin
 
-实现原理：
+利用 `ipmitool sdr` 命令， 采集硬件的温度、功率、电压等信息，并转化为指标。 依赖工具 `ipmitool`，所以需要安装`ipmitool`。

-### 采集配置
-使用[categraf](https://github.com/flashcatcloud/categraf)中[inputs.ipmi](https://github.com/flashcatcloud/categraf/tree/main/inputs/ipmi)插件采集服务器指标:
-```yaml
-cat /opt/categraf/conf/input.ipmi/conf.toml
-  [[instances]]
-  ## optionally specify the path to the ipmitool executable
-  # path = "/usr/bin/ipmitool"
-  ##
-  ## Setting 'use_sudo' to true will make use of sudo to run ipmitool.
-  ## Sudo must be configured to allow the telegraf user to run ipmitool
-  ## without a password.
-  # use_sudo = false
-  ##
-  ## optionally force session privilege level. Can be CALLBACK, USER, OPERATOR, ADMINISTRATOR
-  # privilege = "ADMINISTRATOR"
-  ##
-  ## optionally specify one or more servers via a url matching
-  ##  [username[:password]@][protocol[(address)]]
-  ##  e.g.
-  ##    root:passwd@lan(127.0.0.1)
-  ##
-  ## if no servers are specified, local machine sensor stats will be queried
-  ##
-  servers = ["ADMIN:1234567@lan(192.168.1.123)"]
-
-  ## Recommended: use metric 'interval' that is a multiple of 'timeout' to avoid
-  ## gaps or overlap in pulled data
-  interval = "30s"
-
-  ## Timeout for the ipmitool command to complete. Default is 20 seconds.
-  timeout = "20s"
-
-  ## Schema Version: (Optional, defaults to version 1)
-  metric_version = 2
-
-  ## Optionally provide the hex key for the IMPI connection.
-  # hex_key = ""
-
-  ## If ipmitool should use a cache
-  ## for me ipmitool runs about 2 to 10 times faster with cache enabled on HP G10 servers (when using ubuntu20.04)
-  ## the cache file may not work well for you if some sensors come up late
-  # use_cache = false
-
-  ## Path to the ipmitools cache file (defaults to OS temp dir)
-  ## The provided path must exist and must be writable
