I. What is SNMP?
I. What is SNMP?

First, let's start with the basics.

SNMP stands for Simple Network Management Protocol. It is a protocol used for managing and monitoring network devices such as routers, switches, servers, printers, and more. SNMP allows network administrators to collect information about the performance, availability, and usage of network devices, as well as to configure and control them remotely. The first SNMP standard, called RFC, was first published in May 1990 and has greatly evolved since then. Although there are now other telemetry protocols that exist, SNMP remains the base protocol supported by the majority of network equipment.

SNMP operates by sending messages, known as "protocol data units" (PDUs), between SNMP agents (running on network devices) and SNMP managers (running on monitoring systems). The PDUs contain information about the device's status, configuration, and performance, which can be used by the SNMP manager to monitor and manage the device.

SNMP is a widely used protocol in network management and monitoring, and is supported by most network devices and monitoring systems. It is a simple, efficient, and effective way to keep track of your network and ensure that everything is running smoothly.

SNMP monitoring is the process of using SNMP to collect and analyze data from network devices in order to monitor their status, performance, and usage. SNMP monitoring involves two main components: SNMP agents, which are installed on network devices to collect and transmit data, and SNMP managers, which receive and process the data from the agents.

SNMP monitoring allows network administrators to keep track of a wide variety of metrics related to network devices, such as CPU usage, memory usage, network traffic, and more. By monitoring these metrics, administrators can identify potential issues before they become critical, troubleshoot problems quickly, and optimize the performance of their network.

SNMP monitoring can monitor devices such as:

  • Routers
  • Switches
  • Firewalls
  • Servers
  • Wifi APs
  • And other devices that are SNMP enabled

SNMP monitoring can be performed using a variety of tools, ranging from simple command-line utilities to complex network monitoring software.

SNMP Monitoring Step 1. Enable SNMP Polling for Network Device Monitoring
SNMP Monitoring Step 1. Enable SNMP Polling for Network Device Monitoring

Many Network Device Monitoring tools, like Obkio, use SNMP monitoring within their Network Device Monitoring features.

  1. Obkio's Network Performance Monitoring tool sends an SNMP request to a device, asking it to provide information about a specific metric, such as CPU usage, bandwidth utilization, or uptime.
  2. The device receives the request and responds with the requested information, which is sent back to Obkio.
  3. Obkio's app collects the information from the device and stores it in a database, where it can be used for analysis and reporting.
  4. Obkio can then use this information to identify issues, troubleshoot problems, and optimize the performance of the network and its devices.

SNMP Polling typically operates on a scheduled basis. Obkio sends requests to devices at regular intervals (e.g. every 30 seconds ), and collects the responses over time to create a historical record of performance metrics. This allows you to track changes over time and identify trends that may indicate potential issues or opportunities for optimization.

With Obkio, you don’t need to establish VPNs between a centralized monitoring server and the LANs where the network devices are located because all the SNMP polling is already done by Obkio’s Monitoring Agents.

SNMP Monitoring Step 2. Deploy SNMP Monitoring Agents
SNMP Monitoring Step 2. Deploy SNMP Monitoring Agents

Before you can begin monitoring your network devices with SNMP monitoring, you need to deploy at least one Monitoring Agent.

Monitoring Agents are a unique software developed by Obkio to monitor network performance in key network locations (data centers, branch offices, clouds etc.). They continuously exchange synthetic traffic in your network to measure performance using key network metrics, and identify performance issues.

You need a Monitoring Agent deployed so that it can communicate with your network device to measure performance. We always recommend using the Agent closest to the device you want to monitor.
