Open Source SNMP tools help identify and monitor networks. It supports a wide variety of network devices and operating systems.

Open source SNMP tools enable various devices to connect and share information. In this article, we will learn more about SNMP and its open-source tools.

Top 14 Open Source SNMP Tools

What is open-source SNMP?

SNMP stands for Simple Network Management Protocol. It is an internet standard application layer protocol to collect and organize information on devices connected to the network.

Open source is software that uses an open development technique. It allows the computed functions to be freely available. 

Open source SNMP refers to the tools that enable its users to develop the tools as per their requirements. Open source SNMP is important for effective network management.

Organizations use open-source SNMP tools to manage devices on a network. The devices could be connected to a Local Area Network (LAN) or a Wide Area Network (WAN).

Open Source SNMP Architecture

Open source SNMP is based on simple client-server model-based architecture. The two important components are:

  • Managers: Managers are the servers in SNMP. They collect and process information on the network devices.
  • Agents: Agents are the clients in SNMP. It refers to devices or device components connected to a network.  
  • NMS: NMS refers to Network Management Systems. It is software that runs on the managers to monitor its functions.

What is SNMP used for? Features of Open Source SNMP Tools

Open source SNMP tools play an important role in network management. It effectively secures, monitors, and manages devices on the network.

It is one of the widely accepted internet protocols. SNMP agents can be easily enabled and configured to communicate with network monitoring tools and NMS.

SNMP agents maintain a database of the information collected from devices. The information is then requested and translated as required by NMS.

The database is commonly known as Management Information Base. It functions as a set of queries to the agents requested by the managers.

Open source SNMP Tools are popular among network admins. They rely on the open-source tools that best suit comprehensive monitoring requirements.

The best open source monitoring tools provide high-level security for networks. Open source SNMP tools also provide a variety of messages to help set up network monitoring.

SNMP helps control and manage the status of network devices on the network. 

The best open source SNMP tools provide in-depth monitoring which leads to clear, concise, and rich information. The information can also be used to make better decisions and actions.

Importance of a Network Monitoring Tool

Ever wondered, “Why do I need a network monitoring tool?” “What is happening on my network?”. A network monitoring tool detects devices, traffic, and servers on a network.

There are many reasons to employ network monitoring tools. Here is the importance of a Network Monitoring Tool and its role for organizations:

  • The most important role of any network monitoring tool is to identify connected devices. Identifying each IP address can be a tedious task.
    Hence, the tool helps identify unauthorized devices to be connected by using the network’s regular and scheduled monitoring feature.
  • Network monitoring tools map out a network once it identifies the devices. The mapping is done according to physical links, or for devices connected through wireless mediums.
  • A networking monitoring tool discovers the status of a device. With single and multiple monitor types it runs tests and sends out an alert to the team for further investigation.
  • The switches and routers send compact data to the tool using NetFlow or sFlow for assessment. The tool can easily monitor the traffic on the website and identify issues in case a device is overburdened.
  • A network monitoring tool sends out alerts in case a system is down and is affecting the flow of work. This feature of alerting and integration capability is known as incident response.
  • A network monitoring tool can also use APIs like Azure and AWS. Network monitoring tools help monitor the connected cloud and can identify users to save cost.
  • Network monitoring tools benefit applications, software, and solutions. It monitors the applications for any discrepancies or failures.

SNMPcollector

SNMPcollector is one of the full-featured and open source tools. It is a general data collector that enables Web Administration Interface for InfluxDB.

It aims to simplify the alignment for collecting data from various sources. The sources connected to the network and support SNMP send the data to the InfluxDB backend.

SNMPsim

SNMP Simulator is one of the open-source and pure Python tools to execute the SNMP agents simulator. It is distributed and complies with the BSD License.

The open-source SNMP tool collects data from network traffic and tcdump snoops. It also stores snapshots collected from agents for future simulation.

It is a pure Python solution that is easy to deploy and is highly portable.

Collectd

Collectd is a tiny daemon that gathers information from a system. It enables mechanisms to collect and observe the values in different techniques.

It is an open-source monitoring tool to retrieve and manage SNMP master agents. 

Reconnoitre

Open source SNMP tools like Reconnoitre are a robust security solution. It collects multithreaded information and service enumeration.

It builds directories for IT structures that store results from various sources. It automates collecting information using suggested commands and directory structures.

Sharpsnmplib

Sharp SNMP Library is an open-source tool for .NET and Mono. It functions as a source code repository for SNMP. 

Sharp SNMP Library is one of the open-source tools that can be integrated into Windows. It requires Visual Studio 2019 and .NET Core SDK for compilation.
