我正在尝试为 Telegraf 创建一个新的 UPS.conf 文件，以通过 SNMP 从一批 ups 设备中收集数据。当通过 SNMPGet 查询 OID 时，主机名和 upsType 等输入返回一个字符串，但是当使用 Telegraf 运行时，我只得到整数结果。

我的 UPS.conf 文件

 [[inputs.snmp]]
      agents = [ "192.168.15.60", "192.168.15.64" , "192.168.15.65","192.168.15.66","192.168.15.67" ]
       ## Timeout for each SNMP query.
       timeout = "10s"
       ## Number of retries to attempt within timeout.
       retries = 3
       ## SNMP version, values can be 1, 2, or 3
       version = 3

       ## SNMP community string.
       community = "heabc"
    #
    #   ## The GETBULK max-repetitions parameter
    #   max_repetitions = 10
    #
    #   ## SNMPv3 auth parameters
        sec_name = "grafana"
        auth_protocol = "SHA"      # Values: "MD5", "SHA", ""
        auth_password = "redacted"
        sec_level = "authPriv"   # Values: "noAuthNoPriv", "authNoPriv", "authPriv"
    #   #context_name = ""
        priv_protocol = "AES"         # Values: "DES", "AES", ""
        priv_password = "redacted"
    #
    #   ## measurement name

telegraf --test --config UPS.conf 的输出- 注意每个主机名，一个是 121，一个是 91、82 等。 upsType 字段也以字符串形式出现，但正在转换为数字。

snmpget -v2c -c heabc 192.168.15.60 .1.3.6.1.4.1.318.1.1.1.1.1.1.0 的输出 - 它返回一个字符串。

iso.3.6.1.4.1.318.1.1.1.1.1.1.0 = STRING: "Smart-UPS X 3000"
