Introduction

Simple Network Management Protocol (SNMP) is an Internet Standard protocol for collecting and organizing information about managed devices on IP networks and for modifying that information to change device behavior. Devices that typically support SNMP include cable modems, routers, switches, servers, workstations, printers, and more.

An SNMP-managed network consists of three key components:

• Managed devices
• Agent – software which runs on managed devices
• Network management station (NMS) – software which runs on the manager

EdgeSense SNMP-NMS

EdgeSense SNMP-NMS is a plug-in of RMM agent, aim to collect  object data from SNMP managed device.

Feature:

• Support SNMPv1, SNMPv2c.
• support object type: OCTET STRING, Integer32

How to

Turn MIBs file into JSON documentation

Because MIBS file is not good to load in application, EdgeSense SNMP-NMS use a tools from PySMI to turn MIBS file into json file.

About installing PySMI or more detailed, please refer to this.

Usage:

mibdump.py --generate-mib-texts --destination-format json YOUR_MIB_FILE

example:

mibdump.py --generate-mib-texts --destination-format json ./ADAM-6017.mib

Then a json file will be generated. You can edit this json file to add/remove object you want to poll from several SNMP agents.

Software Requirements

Software Installation for Ubuntu 16.04

Install Steps:

1. Install OS - Ubuntu 16.04 (ex: ubuntu-16.04.5-desktop-amd64.iso)

2. Install MQTT Broker

• Copy MQTT Broker install package (ex: MQTTBrokerSetup-1.0.4-Ubuntu_16.04-x86_64.run) to gateway.
• Execute "sudo chmod +x MQTTBrokerSetup-1.0.4-Ubuntu_16.04-x86_64.run".
• Execute "sudo ./MQTTBrokerSetup-1.0.4-Ubuntu_16.04-x86_64.run" to install.

3. Install EdgeSense SNMP-NMS

• Copy SNMP-NMS install package (ex: SNMP-NMS-1.0.0-Ubuntu_16.04-x86_64.run) to gateway.
• Execute "sudo chmod +x SNMP-NMS-1.0.0-Ubuntu_16.04-x86_64.run".
• Execute "sudo ./SNMP-NMS-1.0.0-Ubuntu_16.04-x86_64.run" to install.

After installation, service will be autorun.

NOTE: Please wire the gateway to Internet with Network cable before install, it is necessary to install the dependencies. 

Uninstall Steps:

1. Execute "sudo /usr/local/EdgeSense/SNMP-NMS/uninstall.bash" in terminal.​
