Custom beat for snmp monitoring in firewall and sending data to Elastic or Logstash. Support snmpget and snmpwalk.

Este codigo esta basado en https://github.com/isalgueiro/otilio, se agrego soporte de snmpwalk.

snmpbeat:
  # Defines how often an event is sent to the output
  period: 1s

  # SNMP hosts to query
  hosts: ["192.168.1.1", "192.168.1.2"]

  # SMNP version: 1, 2c or 3
  version: 2c

  # SNMP community
  community: "public"

  # oids to query
  # (the starting dot is intended)
  oids:
    - {oid: ".1.3.6.1.2.1.1.1.0", name: sysDescr}
    - {oid: ".1.3.6.1.2.1.1.3.0", name: sysUpTime}

This will get oids 1.3.6.1.2.1.1.1.0 and 1.3.6.1.2.1.1.3.0 from SNMP servers at 192.168.1.1 and 192.168.1.2 and store them in otilio-YYYY.MM.DD index in Elasticsearch in fields sysDescr and sysUpTime.

SNMP V3 configuration example

snmpbeat:
  # Defines how often an event is sent to the output
  period: 1s

  # SNMP host to query
  hosts: ["127.0.0.1"]
  port: 10161

  # SMNP version
  version: 3

  # SNMP user security model parameters
  # currently only SHA auth and DES encryption supported ¯\_(ツ)_/¯
  user: "theuser"
  authpass: "theauthpassword"
  privpass: "theprivacyencryptionpassword"

  # oids to query
  # (the starting dot is intended)
  oids:
    - {oid: ".1.3.6.1.2.1.25.1", name: hrSystem}

./snmpbeat -c snmpbeat.yml -e -d "*"
