SNMP Monitoring Will Improve Your Fault Management

In the world of network management, Simple Network Management Protocol (SNMP) is the most commonly used protocol for, you guessed it, network management.

What is SNMP? What can it do for you? How can you use it successfully?

Let's get started.

What is SNMP?

SNMP is a protocol (a shared machine-to-machine language) that allows for communication between different network devices.

It uses Protocol Data Units (PDUs) to exchange data between the SNMP agent (some kind of remote device) and the (central) SNMP management software.

The 4 key components of SNMP monitoring

The key components of SNMP monitoring are:

  1. Monitored device
  2. Management information base (MIB)
  3. Alerting system
  4. Performance metrics

Each network device within an SNMP-based system houses an SNMP agent, a piece of software that collects vital performance metrics about the device it resides on. More commonly, you'll hear the entire device referred to as an "SNMP agent". Technically, the agent is just one subcomponent of the device.

This system allows users like you to monitor performance metrics, environmental levels, and equipment alarms remotely. You can also set up alerts systems in order to detect when something is wrong with your network/operation.

Overall, SNMP can be used to proactively manage and maintain your network environment, ensuring that all devices are running correctly and efficiently.

Examples of SNMP communication and usage

As a generic example, let's say an unexpected issue occurs on a network device. The SNMP agent on that device would send an SNMP trap.

Think of an SNMP trap as really just something like an "urgent email message" sent to the network manager when a device encounters a problem. The trap message informs the SNMP management software of the issue, prompting an immediate on-screen alert (or emails or text messages or other outbound alerts, depending on the urgency).

In addition, one of the most appreciated features of modern SNMP monitoring software is its ability to automatically discover new devices on the network. Network discovery can help you stay updated about every new device under your monitoring umbrella without any additional manual effort.

SNMP can increase both your effectiveness and your efficiency

SNMP is a crucial tool that aids in identifying and responding to network issues both effectively and efficiently.

Effectiveness and efficiency are both important concepts in fault management:

  1. You absolutely must detect and respond to threats before they explode into a major service outage. This is the importance of being effective.
  2. Once you've figured out how to stop major disasters, it's best for your long-term success to do so as efficiently as possible.

Used properly, SNMP will help you accomplish both of these goals.

The Value of SNMP Monitoring in Fault Management

Fault management is about detecting, isolating, and correcting faults in a networked system, and SNMP plays a key role in this process.

As we've discussed already, SNMP traps have properties that make them particularly useful in fault management. They allow the system to notify network managers of potential issues that arise.

Your SNMP monitoring software can be configured to detect specific events or thresholds, and react automatically, for example, by sending alerts or even triggering automatic corrective scripts.

It's hard to imagine a better definition of "fault management" than that.

How do you get started with SNMP?

Getting started with SNMP is straightforward. You'll need a few key components to set up your monitoring system:

  • A monitored device (host or router) that contains an SNMP agent.
  • A Management Information Base (MIB) file containing information about the performance metrics available for each device you want to monitor.
  • An SNMP monitoring tool that can receive the SNMP traps from each monitored device and interpret the various performance metrics in those traps to generate alerts or other important information.

Once these components are in place, you'll be able to start gathering data about your network devices and gain better visibility into their performance and alarm conditions.

Armed with this knowledge, you'll be able to monitor the performance of your network devices more effectively and identify any faults before they become major problems with major financial impact.

SNMP monitoring will transform your real business results

SNMP monitoring, with its wide range of monitoring capabilities, plays a vital role in effective fault management. It equips network administrators like you with the tools you need to stay one step ahead, ensuring optimal network performance at all times.

Monitoring using SNMP is one of the most effective methods of performing fault management within an organization. With SNMP, you can monitor and manage your networks more effectively with the help of trap messages sent by the devices in the network.

SNMP-powered tools allow administrators like you to gain insight into your system performance metrics and issue alerts when any fault occurs, no matter which layer is the source of the problem.

Device examples: NetGuardians and T/Mon are equipped for SNMP

RTUs and central master stations are two major categories of SNMP-capable devices.

NetGuardians, for example, are an excellent option for gathering information from critical points in your network. These all-in-one RTUs can monitor multiple devices at once and send out notifications if any of them experience a fault or performance issue.

T/Mon is another great example of an SNMP-capable device that can be used to monitor and manage large networks with ease. With its central master station design, T/Mon gives you the ability to monitor a wide range of device alarm conditions and provide better visibility into your overall system performance metrics.
