Bandwidth monitoring with ntop & Monitis

POSTED ON: March 12, 2012 POSTED BY Dan Fruehauf

ntop bandwidth monitor

ntop is a very simple yet powerful bandwidth monitor which outputs various statistics counters in RRD.
RRD – Round Robin Database – is a very handy framework for saving server performance counters in a ring buffer.
We can say that if we would like to graph network performance, ntop does most of the hard work for us and all we have left to do is to graph the counters.
Among the counters ntop exposes there are:

Total bytes per interface
Total HTTP, DHCP, DNS, NetBIOS bytes per interface
Interface throughput
IGMP, ARP statistics

And speaking of graphing, we have Monitis, which can graph any counter we can think of. I have an idea – lets graph ntop data with Monitis!

Superb Real User Webpage Performance Monitoring with Jiffy and Monitis

POSTED ON: March 5, 2012 POSTED BY Dan Fruehauf

Webpage performance

Web page performance as opposed to website performance is a bit more of an intricate job requiring familiarization with what is actually served on your website and how your web pages are woven together.
If we’re talking about website performance – we most likely refer to web server performance – how fast requests are being served or what’s the percentage of failed requests for instance.
Opposed to that, web page performance, or at least what I am referring to is the equivalent of asking the following invaluable questions:

How fast/slow is my web page in general?
Are there excessively slow parts at my web page?
If my web page is indeed slow, where is the bottleneck?

And guys, for this, there is a solution. It is a really handy utility called jiffy-web.

Integrating Open Source Monitoring With Monitis

POSTED ON: February 24, 2012 POSTED BY Hovhannes Avoyan

In this post, we’re going to examine two popular open source monitoring methods and their integration with the Monitis platform. The first open source monitoring method we’ll discuss is Nagios — which allows you to monitor any network service with the use of plug-ins. The second is Munin — another software monitor with it’s own strengths and weaknesses.

M3 Timers – improved server monitoring

POSTED ON: February 10, 2012 POSTED BY Dan Fruehauf

Unleashing the power of M3 & timers

During the lifespan of M3 (Monitis Monitor Manager) there has always been something lacking – timers.

M3 execution procedure was outlined in this previous article.

The execution mentioned in the latter was a one-time-execution, whereas server monitoring requires periodic invocation of monitors in order to actually provide counters over time, graphing performance.

The periodic invocation method suggested up until today was to integrate M3 with crontab.

Crontab, in a nutshell, is a Linux/Unix service for periodic invocation of executables. Implementing M3 with crontab properly meant M3 would run every X minutes, producing a Monitis counter update every X minutes, should everything run properly.

In the following article I’ll outline the changes done to support timers in M3.

Network Bandwidth Monitoring Made Easy

POSTED ON: February 7, 2012 POSTED BY Ard-Jan Barnas

In this article we’ll create a Monitis custom monitor to measure your network bandwidth or throughput. The monitor will support multiple network adapters and should be intelligent enough to only collect results for the network adapters that are active.

First, let’s take a look at the performance counters we used for this monitor and the information each metric provides.
