Those interested in the paid version have three choices of plans: Standard, Professional, and Enterprise. All versions are available for installation on Windows Server and Linux.
Access a day free trial of ManageEngine OpManager:. With Kiwi Syslog Server Free Edition you can collect, view and archive up to 5 sources including routers, computers or other devices. Logs may also be written to disk—either in one large file or split up by day or priority. You can view logs in real-time, gather stats, and even setup warnings and alerts. If you want to get more serious, I recommend upgrading to the full version.
Nagios is a networking monitoring software solution. With Nagios XI you can monitor everything from infrastructure to applications with granular detail.
With Nagios Log Server, you can quickly sift through a central repository of audit logs, or setup triggers to alert you to critical events such as threats. And with Nagios Network Analyzer, dig deep into the health and integrity of your systems and network.
Analyze flows, validate intent and troubleshoot with the lights on. What I like most about Nagios is their straightforward approach to monitoring. They have multiple ways to represent data visually, which is another key interest of mine.
Lastly, the built-in failover is wickedly cool if you start monitoring larger environments. Named after the popular top command in Unix, ntop shows network usage similarly to how top shows system usage. Ntopng, based on libpcap, is the next generation version of the original ntop. It was written in a portable manner, which gives it the flexibility to run on numerous platforms: Linux, Mac OSX, and Windows.
Web-based, ntopng allows you to view traffic data and gather reports regarding network status. You can even do long-term reports to collect metrics such as throughput over time. I personally use this tool to generate detailed host-based reports showing applications latency, RTT, TCP statistics like retransmissions, out-of-orders, and zero windows.
As a bonus little feature, you can actually authorize specific IPs or ranges to limit sending and receiving directly to the server for advanced security. You can authorize specific IPs or ranges to limit sending and receiving directly to the server for advanced security, and run it as a service on a centralized server.
I am intimately familiar with several very large networks that use SolarWinds NCM for configuration, compliance and image transfers. Wireshark is an unparalleled network protocol analyzer , and honestly, one of the best free network tools ever made. Never leave home without it! A simple ping between the two nodes is only good for general reachability and understanding the round-trip time for the small packets. You run the client on two ends of a network, configuring the parameters needed to measure performance.
Upon execution, it actively measures and reports on bandwidth, loss, latency, jitter, and so on. You can initiate multiple simultaneous connections to truly simulate load across the network.
Very handy tool! I personally use Nmap at least once a week. To accomplish its goal, Nmap sends specially crafted packets to the target host and then analyzes the responses. Nmap provides an incredible number of features for probing networks, including host discovery, service discovery and operating system detection.
These features are extensible by scripts that provide more advanced service detection, vulnerability detection, and other features. In fact, Nmap is used in the backend for various security assessment tools such as Nexpose. SNMP can be hard. This is why you need a good tester.
Are your devices configured properly? Are you using the correct keys? Angry IP scanner is an open-source, multi-threaded IP address and port scanner. Angry IP Scanner first rapidly pings, then checks port status, then starts resolving hostnames, gathering MAC addresses, OSs and whatever it can discern based on the data gathered.
It can collect NetBIOS info like workgroup and domain names, as well as logged-in users if you happen to have to privileged rights to retrieve this information. Runs on Windows, Mac, and Linux.
Get it here. Ansible is a simple and powerful automation engine with the goal of reducing repetition by automating tasks. From a network perspective, I like this tool for generating configuration files based on my custom templates. Super clean. Created by Kirk Byers, Netmiko is a multi-vendor Python library that simplifies Paramiko, gearing it toward network devices. As with any software […]. Optimal temperature is essential for good health. This statement applies to living beings and computer components because they are designed to perform well only when the temperature is within a specified range.
Now […]. Every piece of information transmitted over the Internet is split into small packets, numbered, and transmitted. The receiving device receives these packets and constructs the message based on the numbering and other information present in the header of each packet. Sounds simple, right? In the real world, though, the packets can get lost en route […].
In other words, the […]. Managing a data center is anything but easy given the multitude of systems and devices and the complexity of ensuring that each of these work at optimal levels always. Besides the software and hardware, an organization also has to ensure that the cooling units are correctly wired and are working fine. Such a mammoth list […]. However, just like any other tools, it has to be well-managed and monitored to ensure that it is up and running at all times in optimal health.
Here is our list of the Best Azure Monitoring Tools: […]. Databases are an integral part of every software, and system infrastructure as this is the layer that stores data and retrieves it when needed. Since the process of storage and retrieval is critical for any application, you must ensure that the database is in optimum health and performance at all times. Also, any improvements or […].
Monitoring has become an essential part of the IT infrastructure today, but have you ever wondered how monitoring happens for distributed applications over many functions and services? Add in agents and wrappers to the mix, and you have one of the most complex setups in the IT world. This is a unique challenge with the […].
Digital communication appears instantly and seamless to us today, but many complex processes happen in the background. This is an application layer protocol defined by the Internet Architecture Board to enable seamless communication between […]. Active Directory is commonly used across organizations to segment user accounts, so they can be given the appropriate access to resources.
Often, one or more accounts that have similar characteristics such as belonging to the same department, accessing the same resources, etc are grouped for better management.
