We’ve also improved the user rights management mechanism and added a lot of useful features.

Now, a little more detail on the most important features.

Monitoring Switch Configuration Changes

In any corporate network, switches are more than just “boxes with ports.” They are critical nodes that determine the topology, security, performance, and availability of the entire infrastructure. Their configurations constitute the precise “genome” of the network: VLANs, ACLs, ports, STP, QoS, trunk settings, inter-VLAN routing, and much more. More

Poll Server Hardware Sensors via IPMI and Use Updated Map Editor in the New 10-Strike Network Monitor Pro 8.1

News, Updates , 0 Comments

In the summer update of our network monitoring program, we have added several useful “goodies” including the new IPMI server hardware monitoring function. The map editor was significantly improved in both the desktop and web versions of the program.

We tell you in detail…

Poll Server Hardware via IPMI

IPMI (Intelligent Platform Management Interface) is a standard interface for remote management and monitoring of server hardware that works independently of the operating system. It allows administrators to turn the server on/off, reboot it, mount disk images for OS installation, and monitor various hardware parameters such as temperature and fan speed, even if the server is turned off or unresponsive. The hardware controller (BMC) integrated into the motherboard is responsible for the operation of this interface. This means that it always works as long as there is power and does not depend on whether the operating system is running.

The program receives a list of sensors from the server so that you can quickly configure monitoring of one of them (in one check). Then it periodically polls it and compares the value with the specified one, signaling when threshold values are exceeded. For example, with the help of this check “IPMI Sensors” you can promptly find out about the beginning of server overheating or that one of the coolers has failed.IPMI server hardware monitoring - fan speed - temperature

You can receive the data from the controller via IPMI either directly, using the login and password for connection, or via the agent service installed on the remote server.

What is Syslog: Things You Need To Consider

Articles , 0 Comments

In today’s complex IT environments, effective logging and monitoring are critical for maintaining system integrity and security. Syslog, a foundational tool in centralized logging, enables organizations to log system messages and events across devices and applications. By transmitting log messages to a centralized syslog server, Syslog simplifies log management, allowing organizations to store, analyze, and act on important data efficiently.

 

What is Syslog?

Syslog is a standardized protocol for collecting and managing system messages in networked environments. It enables log data transmission from various devices and applications to a centralized server for efficient management and analysis.

 

History of Syslog

Syslog was developed in the 1980s by Eric Allman as part of the Sendmail project, which was a widely used mail transfer agent in Unix systems. It quickly became a de facto standard for centralized logging due to its simplicity and effectiveness in capturing log messages from various sources.

The protocol was not formally standardized until 2001 when the Internet Engineering Task Force (IETF) published RFC 3164, known as “BSD syslog.” This document outlined the basic structure and transport methods for syslog messages. In 2009, RFC 5424 superseded RFC 3164, introducing enhancements such as ISO-8601 timestamps, structured data fields, and support for UTF-8 encoding.

Initially, syslog messages were transmitted using User Datagram Protocol (UDP), which is fast but does not guarantee delivery. Over time, support for Transmission Control Protocol (TCP) and the Reliable Event Logging Protocol (RELP) was added to ensure more reliable message delivery. Modern implementations also support TLS encryption for secure transmission of log data.

This article delves into the fundamental Linux performance monitoring methods and tools that showed themselves as efficient for server monitoring.

 

Understanding ICMP Ping Monitoring

ICMP (Internet Control Message Protocol) ping monitoring is a fundamental technique for assessing the availability of a host over a network. By sending ICMP Echo Request packets to a designated host and waiting for Echo Reply packets, administrators can determine whether a server is reachable. This method is particularly useful in Linux network monitoring, as it provides a quick check on the status of Linux servers and other devices. 

Benefits of ICMP Ping Monitoring

  • Fast Availability Checks: ICMP ping is one of the quickest methods to ascertain if a server is online, making it a staple in network performance monitoring. For instance, a data center can use ICMP monitoring to quickly detect network outages and ensure connectivity for mission-critical applications.
  • Basic Diagnostic Tool: It helps identify issues in network traffic and intermediate network nodes, required for network management.

Geomap and the SSH script alert reaction in the new LANState Pro 10.4

News, Updates 0 Comments

In the new version of the network administration and monitoring tool 10-Strike LANState Pro 10.4, we have added the ability to place host markers on the Open Street Map (OSM) geomap, bind them to addresses, and perform certain actions with them via the context menu. The geomap allows you to monitor the status of hosts, quickly determining where exactly the equipment failure occurred. The map is easily scaled and moved with the mouse along with the host markers.geo map with host markers - host network monitoring

The geomap can be displayed either in a separate window or embedded in the main one. In the first case, the window with the map can be dragged to a separate screen – it will not interfere with the work with the program in the main window.

In addition, a new reaction to the check result has been added to the program. Now you can execute SSH scripts in response to failure alerts (this also works for receiving SNMP trap and Syslog messages). You can enable the execution of bash scripts and commands via SSH on the Execute script tab of the notifications section in the monitoring check properties. More

Map editor in web interface, Netflow dashboard, IPFIX support, new actions, and Firebird 5 in the big update of 10-Strike Network Monitor Pro 8.0

News, Updates , 0 Comments

We planned to release another update of the network monitoring program before the New Year holidays. However, we thought about it and decided to include more new features, which we are sure you will appreciate. One of them is a map editor in the web interface application! We made the same editor as in the desktop console. Well, almost the same. Of course, in terms of capabilities, it does not yet reach the level of a full-fledged one, but we are constantly working on it. Now you can add new areas, hosts to the map and connect them with lines. And, of course, move objects, resize, and delete them.

Geographic map (geomap) in the new version 7.6 of 10-Strike Network Monitor Pro

News, Updates , 0 Comments

The new version of the program for monitoring video surveillance systems, servers, and network equipment 10-Strike Network Monitor 7.6 again has got a lot of new functionality. We are happy to please you with an interactive geo-map based on the Open Street Map platform, on which you can now place the host icons! We also added the ability to monitor devices with dynamic addresses and updated the library for working with motherboard sensors – now the program supports a large number of new equipment for monitoring the CPU temperature, fan speeds, etc.

Let’s review in details about all this.

 

Place hosts on the geographic map

The program could place host markers on a city map, but we used raster backgrounds for this. The icons could not be tied to specific street addresses so that they would not move when the map was enlarged. With the new geomap feature, this problem is solved now. The interactive Open Street Map now allows you to place host markers that are assigned to geographic coordinates or addresses.

Create a failover cluster of monitoring servers, search for new devices on the network, and monitor the Linux performance metrics in the new version 7.5 of 10-Strike Network Monitor Pro

News, Updates , , , , 0 Comments

We are breaking into spring with a new version of the program for monitoring video surveillance systems, servers and network equipment Network Monitor 7.5! Lots of improvements – both small and large. The most important thing is that we made a background search for new devices, added the ability to operate the program in a failover cluster, and added the new check of “Linux Metrics”. We tell you more about the main innovations.

Search for new devices

Finding new hosts on the network has become much easier. You don’t need to manually launch the scanner each time – the built-in task scheduler will do it automatically and completely unnoticed. Network scanning is performed by the monitoring server in the background. In case of detection of new addresses, the program notifies in several ways, as when performing checks. And if the graphical console is running at the time of notification, you will receive a message from which you can immediately go to the list of found hosts and add them to the monitoring database.

Search for new devices is implemented as one of the Scheduler tasks – look for this function there. For ease of configuration, we have moved it to a separate button on the main toolbar. To enable this task, you need to configure scanning parameters (range, methods, logins), notifications and launch interval.

Backup monitoring server for a failover cluster of monitoring servers

We have already made it possible to quickly reconnect the monitoring server to the backup database server if it fails. But what if the monitoring server itself fails? We have provided for this and made it possible for two monitoring servers with the same ID to work in the same network simultaneously without conflicts (in the version Pro that supports multiple monitoring servers).
