Showing results for 'snmp gui' as the words mac, app are considered too common MIB Browser - SNMP Monitoring MIBBrowser is a tool which provides SNMP monitoring information via GUI, so you can browse SNMP information with it. Understanding SNMP will help you better appreciate the upcoming product reviews and help you configure and use any SNMP monitoring tool. Most texts explaining SNMP will tell you about MIBs, OIDs, and several other TLAs (Three Letter Acronyms). We think this is overkill, especially in a post such as this one.

Way back in 2015, we reviewed the must-have top free networking tools. And honestly, those reviews have stood the test of time. But now that time has passed, the landscape has changed, and we think it’s worthwhile to review those old choices and possibly add a few new ones.

Laying the Foundation

To build a network, you start with an architecture, draw the design, and analyze and choose the hardware that meets your requirements. Because many organizations need their network to be up and functioning to generate revenue, having the right set of tools to monitor and manage the one you so lovingly created is critical.

But how do you find the best network monitoring tools when there are hundreds of commercial products, freeware tools, and open-source software to choose from? While the debate about free versus commercial goes on, there are tried and tested, free network monitoring tools that many network admins swear by. Below, we will share some of our favorites with you.

But first…

Open-source choices are good and can even match commercial tools, but you should know that using open-source monitoring requires a high level of involvement with the tool, which may not perfectly suit your needs. As the saying goes, “Open-source is only free if your time is worthless.”

Open-source monitoring solutions often require a significant investment in time and resources. Missing features may have to be built with the help of community support or an in-house IT team. The second consideration is security, which may become an issue, depending on the tool you select and your enterprise’s security guidelines. Additionally, immediate custom fixes may not be available unless you spend time developing and maintaining them yourself.

If you’re looking for a robust yet affordable network monitoring tool offering a greater degree of automation and insight and a lesser degree of required manual input than an open-source solution, SolarWinds^® ipMonitor^® may be a good option for you. ipMonitor offers scalable network monitoring for your entire network in an easy-to-use, lightweight, and fast solution designed to help minimize downtime and the amount of time you need to spend monitoring your network by hand.

The tool’s Startup Wizard guides you through the processes of alert configuration and automated discovery so you can quickly start getting insights into your network. ipMonitor even offers out-of-the-box recommendations for what you should be monitoring on each of your applications and devices.

One reason someone may want to use a free network monitoring solution is because they’re intimidated by a paid solution. In fact, paid network monitoring tools are typically much easier to use than their free counterparts. This is certainly true when it comes to ipMonitor, as the user-friendly interface helps you quickly identify current (and even potential) issues so you can get to the bottom of them before they cause even more problems for your network performance. ipMonitor helps ensure you never miss anything with its powerful, configurable alerting system. With more than a dozen different notification types built in, ipMonitor helps you make sure the right people on your team know about potential problems as soon as the tool detects them.

ipMonitor is an affordable option for businesses of any size, but if you aren’t sure whether you want to commit to a paid tool, you can try out a free 14-day trial to see if the tool is a good fit for your needs.

When we need a network monitoring tool that is easy to install, and supports monitoring and reporting out of the box, we like SolarWinds^® Network Performance Monitor (NPM). NPM acts as a single pane of glass to provide complete and comprehensive network monitoring capabilities that complement some of the essential free tools you may already use.

Knowledge Base

Because enterprise networks are becoming bigger and more complex, it’s important to put network monitoring and managing solutions in place early in the implementation phase.

What’s on the list?

If you do decide to go the free/open-source route, you should check out the following. It’s our list of the best free network monitoring tools available today.

Nagios Core

Nagios^® is the great-grand-daddy of monitoring tools, with only ping being more ubiquitous in some circles.

Nagios is popular due to its active development community and external plug-in support. You can create and use external plugins in the form of executable files or Perl^® and shell scripts to monitor and collect metrics from every hardware and software used in a network. There are plugins that provide an easier and better GUI, address many limitations in the Core^®, and support features, such as auto discovery, extended graphing, notification escalation, and more.

Cacti

Cacti^® is another of the monitoring warhorses that has endured as a go-to for network monitoring needs. It allows you to collect data from almost any network element, including routing and switching systems as well as firewalls, and put that data into robust graphs. If you have a device, it’s possible that Cacti’s active community of developers has created a monitoring template for it.

Cacti supports SNMP polling, which itself covers a wide range of network devices. You can also extend Cacti’s capabilities to use scripts, queries, or commands for data collection, and save it as a template to use for polling other devices for similar datasets. Cacti leverages the power of RRDTool, an open-source data logging and graphing system for creating graphs from the stored datasets. RRDTool’s data consolidation lets you store collected data forever and is limited only by the size of your storage. Cacti also allows you to add multiple users and give them access with or without edit permissions, which is perfect for service providers and enterprises with a large NOC team.

Zabbix

Admittedly complex to set up, Zabbix^® comes with a simple and clean GUI that makes it easy to manage, once you get the hang of it. Zabbix supports agentless monitoring using technologies such as SNMP, ICMP, Telnet, SSH, etc., and agent-based monitoring for all Linux^® distros, Windows^® OS, and Solaris^®. It supports a number of databases, including MySQL^®, PostgreSQL^™, SQLite, Oracle^®, and IBM^® DB2^®. Zabbix’s VMware^® monitoring capabilities allow you to customize using any scripting or programming language, which is widely regarded as its best feature.

Zabbix is probably the most widely used open-source network monitoring tool after Nagios.

ntop

ntop, which is now ntopng (ng for next generation), is a traffic probe that uses libpcap (for packet capture) to report on network traffic. You can install ntopng on a server with multiple interfaces and use port mirroring or a network tap to feed ntopng with the data packets from the network for analysis. ntopng can analyze traffic even at 10G speeds; report on IP addresses, volume, and bytes for each transaction; sort traffic based on IP, port, and protocol; generate reports for usage; view top talkers; and report on AS information. This level of traffic analysis helps you make informed decisions about capacity planning and QoS design and helps you find bandwidth-hogging users and applications in the network. ntopng has a commercial version called ntopng pro that comes with some additional features, but the open-source version is good enough to quickly gain insight into traffic behavior. ntop can also integrate with external monitoring applications such as Nagios for alerting and provide data for monitoring.

ntopng has some limitations, but the level of network traffic visibility it provides makes it well worth the effort.
