Otilio

Build Status Go Report Card

Welcome to Otilio. Beat to query SNMP data. This was built following Beats developer guide and uses gosnmp library.

Example setup (see otilo.yml):

otilio:
  # 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

otilio:
  # 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}

Building

Ensure that this folder is at the following location: ${GOPATH}/github.com/isalgueiro/otilio

Requirements

Build

To build the binary for Otilio run the command below. This will generate a binary in the same directory with the name otilio.

make

Run

To run Otilio with debugging output enabled, run:

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

Test

To test Otilio, run the following command:

make testsuite

alternatively:

make unit-tests
make system-tests
make integration-tests
make coverage-report

The test coverage is reported in the folder ./build/coverage/

Update

Each beat has a template for the mapping in elasticsearch and a documentation for the fields which is automatically generated based on etc/fields.yml. To generate etc/otilio.template.json and etc/otilio.asciidoc

make update

Please check index settings, as they may not fit your use case.

Cleanup

To clean Otilio source code, run the following commands:

make fmt
make simplify

To clean up the build directory and generated artifacts, run:

make clean

Packaging

The beat frameworks provides tools to crosscompile and package your beat for different platforms. This requires docker and vendoring as described above. To build packages of your beat, run the following command:

make package

This will fetch and create all images required for the build process. The hole process to finish can take several minutes.
