Observium Community is an intuitive SNMP-based network management and monitoring tool that auto-discovers devices on your network and reports back on their status. It runs on Linux and supports a multitude of device types, platforms and operating systems including Cisco, F5, Citrix, Juniper, Windows, Linux and more.
Start by adding devices to monitor either manually or via the auto-discovery feature, which probes the network looking for SNMP configured devices. After devices have been added, go to the Overview page to review the status of each device.
WirelessNetView is a lightweight utility (available as a standalone executable or installation package) that monitors the activity of reachable wireless networks and displays information related to them, such as SSID, Signal Quality, MAC Address, Channel Number, Cipher Algorithm, etc.
We are looking for a way to continuously monitor our security video servers (have about 40 total in the Ga. region) like our other critical servers out there, in order to ensure the OS is running and we have network connectivity to them in order to minimize downtime. As a possible alternative I would be interested in getting an application we could run that would automatically run through a list of IP addresses of our devices, pinging each one periodically and popping up some kind of alert to tell us if I have a server no longer responding to ping.
There are many ways that network monitoring can help your business out. After all, being able to gauge the health of your servers, user workstations, computer applications etc is crucial to any business.
Out of all the network monitoring tools out there, there are some that can easily break your budget. Thankfully, there are many open source and free options for you to look at, so that you can get the job done without spending money.
In this article I have researched the best open source and free network monitoring software which you can install in your network and start getting statistics, alarms and other useful information about your devices and infrastructure.
This is another open source program that is designed to check the availability of network resources, notify administrators of any outages, and it can also provide performance reports among other monitoring tasks. It is comparable to the popular Nagios.
Open source network monitoring tools are one of the best things for companies that can handle working and integrating such programs into their systems. As long as you have employees who know how to integrate OpenNMS into your business, you can rest assured knowing that you will be able to monitor almost anything.
This is a great free Network Management System software with many happy users. People use LibreNMS to manage and monitor Cisco devices, Juniper, Brocade, Foundry, HP, Pfsense, Linux boxes, telecommunication systems, almost any network device vendors etc.
Being able to monitor things in real time in your IT infrastructure and network is always crucial. Especially when it comes to problems in your networking, where a single problem can mean that your entire business can be down for a few hours or more.
This program specializes in providing all the information you need to know in an easy to read display, so that you can stay on top of your network monitoring, preventing problems before they become detrimental for your business.
If you are an SMB company with limited resources and time to monitor your network and IT infrastructure, then I suggest to invest the money and get the paid version of Solarwinds. Being one of the most sophisticated products in the market, it will surely offer you a complete and hassle-free solution.
If you are running a smaller company, but you still want to make sure that your networking is going okay, then you will want to keep an eye on the community edition of Observium, which offers many of the features and characteristics that you would want with most network monitoring programs.
Observium can be installed only on Linux systems but can easily monitor Windows machines as well plus many other devices and systems such as over 458 different Operating System types, traditional networking equipment (including routers, switches etc), Security and Network Control devices, Wireless devices and much more.
Another community edition of a network monitoring tool is Zenoss Community Edition. This tool makes it very clear that it is neither a demo nor a trial version of its larger products, but rather a smaller version of them, modified to be better suited to smaller systems.
If you are still looking at community editions of network monitoring tools, then Zenoss is another one to consider. Choosing to put your time into such a tool can better your business significantly in the long run.
I like its in-depth network visualization and monitoring capabilities such as Automatic Layer 2 and Layer 3 discovery, Active discovery with scanning probes, passive discovery based on ARP and routing tables of routers, SNMPv3 support etc.
In a way, if you choose to get PandoraFMS while your business is still young and learning, it could potentially grow with your business. Aside from this, it can perform many of the functions that other commercial network monitoring tools can.
A notable feature of NetFlow Analyzer is that it can monitor distributed networks, which is great for cloud-based workflows. Aside from that, you are getting tailored performance reports for Cisco AVC and WAAS along with a few other goodies.
As the name suggests, the ManageEngine option works using NetFlow technology. This means that you must enable and configure Netflow (or other flavors such as sFlow, J-Flow, IPFIX etc) on your network equipment (switches, routers etc) in ordet to send Netflow traffic to collectors for monitoring.
I feel like you're trying to solve the wrong problem here. Shouldn't you be trying to make the ssh daemons more stable? Try running something like monit, which will check to see if the daemon is running and restart it if it isn't (giving you time to find the root problem behind sshd shutting down on you). Or is the network service troublesome? Try looking at man ifup. Does the Whole Damn Thing just like to shut down on you? Well, that's a bigger problem ... try looking at your logs (start with syslog) to find hardware failures or services that are shutting your boxen down (maybe a temperature monitor?).
You can also have access to manage, inspect, and resolve your MAC addresses, IP addresses, and DNS names with monitoring tools like MAC addresses and a DNS resolver. It will alert you on network issues that require your attention immediately by monitoring the servers in your network.
Scan IP addresses and multiple devices on LAN or WLAN and monitor your network. If there are any disruptions in the network, you would receive alarms to take action quickly. In addition to network devices, you can easily monitor network traffic.
PRTG includes Sunburst along with other dashboards that you can access on your PC, tablet, or smartphone to customize it according to your priorities and network requirements.
