사용 예시

Telegraf에 관한 자세한 내용은 influxdata의 Telegraf documentation을 참조하세요.

노트

Telegraf 플러그인 및 에이전트는 사용자가 해당 서비스에 직접 설치하고 설정해야 합니다.

SNMP

SNMP input plugin을 사용하여 SNMP 성능 데이터를 실시간으로 수집 및 차트 표시 가능합니다. 수집된 데이터는 telegraf_snmp, telegraf_interface 카테고리로 검색하실 수 있습니다.

  ## Agent addresses to retrieve values from.
  ##   format:  agents = ["<scheme://><hostname>:<port>"]
  ##   scheme:  optional, either udp, udp4, udp6, tcp, tcp4, tcp6.
  ##            default is udp
  ##   port:    optional
  ##   example: agents = ["udp://127.0.0.1:161"]
  ##            agents = ["tcp://127.0.0.1:161"]
  ##            agents = ["udp4://v4only-snmp-agent"]

  agents = ["udp://1.1.1.1:161"]

  ## Timeout for each request.
  # timeout = "5s"

  ## SNMP version; can be 1, 2, or 3.
   version = 2

  ## SNMP community string.

  ## Agent host tag
  # agent_host_tag = "agent_host"

  ## Number of retries to attempt.
  # retries = 3

  ## The GETBULK max-repetitions parameter.
  # max_repetitions = 10

  ## SNMPv3 authentication and encryption options.
  ##
  ## Security Name.
  # sec_name = "myuser"
  ## Authentication protocol; one of "MD5", "SHA", "SHA224", "SHA256", "SHA384", "SHA512" or "".
  # auth_protocol = "MD5"
  ## Authentication password.
  # auth_password = "pass"
  ## Security Level; one of "noAuthNoPriv", "authNoPriv", or "authPriv".
  # sec_level = "authNoPriv"
  ## Context Name.
  # context_name = ""
  ## Privacy protocol used for encrypted messages; one of "DES", "AES", "AES192", "AES192C", "AES256", "AES256C", or "".
  ### Protocols "AES192", "AES192", "AES256", and "AES256C" require the underlying net-snmp tools
  ### to be compiled with --enable-blumenthal-aes (http://www.net-snmp.org/docs/INSTALL.html)

  ## Privacy password used for encrypted messages.

SNMP Trap

SNMP Trap input plugin을 사용하여 SNMP Trap 이벤트를 실시간으로 수집 및 이메일, 문자 메시지 및 메신저로 전파 가능합니다. 수집된 데이터는 telegraf_snmp_trap 카테고리로 검색하실 수 있습니다.
