PRTG Network Monitor (PRTG)
News From Paessler
I wouldn't be surprised if you told me you have fallen in love with SNMP. Because it is so universal in network administration. Because it is a powerful all-round talent that supplies you with nearly every kind of information you need about whatever network device. Surely you love SNMP, if you know how to set it up on your machine. And if you know what OIDs are and what you need MIBs for. And if your setup is fine, SNMP works reliably (at least it should), and you can live happily ever after.
Unlike simple work computers, server systems have at least two network cards, rather than four NICs. Likewise, many server computers have several IP addresses, which make them accessible from the network. If a computer system has multiple network addresses, this is referred to as "multihoming". Interestingly, the industry uses this conceptuality for several variations: A redundant address with multiple interfaces A server with multiple addresses on several interfaces Multiple addresses on an interface
One of the more general requirements placed on every administrator is that of always maintaining an overview. Every reasonable thinking person will confirm that this is desirable, yet in practice often difficult - if not impossible. But when it comes to IT and its availability, reason is not always the prevailing feature, and administrators can use every conceivable aid to keep their IT under control.
In our article "12 Characteristics of a Well-Maintained LAN", we have several items listed. Each item is important, but I'd like to focus on a couple of these items in more detail: Standardized Naming Conventions Well-Designed Network Addressing and Subnetting You may ask, "Why these two in particular?". Well, in my position as a pre-sales engineer, I encounter problems and issues related to these two fairly frequently. As a IT professional I've battled these issues from several angles. Both being a slave to a network that evolved organically and to a network planned in way too much detail. Neither approach is ideal but both have merit -- like project management, it can either be part of the solution or part of the problem. I'd like to describe the problems and a solution.?
The following article is the last in our 3-part series about CDNs (Content Delivery Networks). Our guest author, Matt Conran from Network Insight, discusses CDN performance metrics and monitoring, what you can do to optimize your website for CDNs, and which strategy is better for CDNs: build or buy?
Regular monitoring of IT resources is part of day-to-day operations in large and medium-sized companies. But even many smaller firms appreciate the advantages of monitoring system usage, open memory space, accessibility, and quality of service. After all, IT would prefer not to have to hear from users that components have broken down, even in these fairly manageable environments. One such "proactivity" that is often sworn by is said to promise smooth processing, wherein, for example, the administrator knows days in advance that hardware space is running low.
Many common network issues can be minimized or avoided altogether with a mixture of proactive monitoring, anticipating problems and planned recovery strategies.
Back in the day, all it took to lure someone into emptying their pockets was an email from a Nigerian prince. Today, scammers are having a much harder time as people are used to these kinds of emails and most of them land unopened in their spam folder. But don't be deceived, scammers are more active than ever and even keener on tricking you into giving them valuable, personal information by posing as a trustworthy source. This tactic is known as phishing and it has proven to be very successful. So year after year, they up the ante, adding new variations here and there. Let's go over the three levels of phishing.
I have been lucky enough to give a number of interviews over the years. Lucky because, if someone decides you are worth listening to enough that they put you in front of a camera, you either really are worth listening to, or you just happen to work for the right company and they think you are! Either way, it's a real privilege and I hope there has been, in my case, at least a mixture of both.? Most interviews have been relatively unprepared and spontaneous, but my most recent rendition was different. Firstly, it was with Business Reporter, an offshoot of the Daily Telegraph newspaper. With a daily circulation of over 460,000, the Daily Telegraph is the most read "broadsheet" newspaper in the UK and 6th overall. As such, the pressure was on to deliver in a way I hadn't experienced before. And secondly, there was a very structured, highly detailed preparation process.
Uptime is obviously near and dear to Paessler's heart. That's why we're excited about establishing "World Uptime Day"?a day for system administrators and their users to celebrate our common goal of reaching 100% uptime.
In an interview last year with Business Reporter, part of the Daily Telegraph newspaper, a major broadsheet in the UK, I outlined my thoughts around how small and medium sized businesses can mitigate risk and reduce downtime by investing in the right technologies. Here are some of my insights.
You've heard of it. You've probably used it countless times. You probably couldn't do without it anymore. But have you ever actually thought about how this simple yet incredibly useful network troubleshooting tool came to be?
The following article is part 2 in a 3-part series about CDNs (Content Delivery Networks), and it's a guest post by Matt Conran of Network Insight. In this article, Matt covers CDN PoP (Points of Presence) architectures, with a detailed discussion of the methods for directing users to the best PoP, including the pros and cons of DNS load balancing versus Anycast.
