Zabbix 4.2: Extending Zabbix monitoring with RESTful microservices

There are a few ways one can gather custom metrics with Zabbix, for example, via user parameters or Zabbix sender protocol. While either method can work for simple metrics, creating a more wholesome approach (with data collectors, persistent connections etc) and interfacing it with Zabbix may not be as trivial.

With the HTTP agent item Zabbix can natively connect to RESTful web services, but the new pre-processing options, “Check for error” and the “Custom on fail”, take it a big step further. This allows us to create web services that can be directly used by Zabbix. To demonstrate we will create a very simple MySQL monitoring web service, returning the number of active and maximum connections.

Zabbix 3.4 – Dynamic Maps

Zabbix 3.4 impressed with its graphical, easy-to comprehend and improved way to access all the gathered data resulting in more interactive, dynamic and visually pleasing network monitoring.

For sure it’s an obvious sign the product moves ahead in terms of more advanced interface, and the use of SVG (Scalable Vector Graphics) instead of a meanwhile outdated raster file format is a good example of the positive changes.

Let’s have a look at all the map improvements in detail with some practical examples:

    • SVG image is a candy for the eyes comparing to a raster one. What catches attention first are smooth and softened edges of the background shape. Text legibility is also affected positively by way of using a modern and stylish font;
    • Zooming doesn’t affect the quality of this type of images, letters remain readable, and no fuzzy edges experienced;
    • The use of SVG images gives a possibility to copy-paste required data for further data analysis, so no more unnecessary memorizing required:

Zabbix 3.4: Mass data collection using Mercury and smartmontools as an example

As we have already mentioned earlier, there are new opportunities for mass data collection in the latest Zabbix version – Zabbix 3.4. Now let’s dwell on this functionality in more detail, and in order to make it more clear, we will tell about it in two examples:

  • one-time collection of the data received in JSON with the console: Mercury 236 electric power consumption meter
  • collection of hard drives and SSDs S.M.A.R.T. attributes obtained in tabular form with smartmontools.

Zabbix 3.0 – Being in Control Never Looked So Good

One of the main highlights of the 3.0 release of Zabbix is a much awaited visual overhaul of the front-end interface. Our main effort was to introduce a more lightweight, less cluttered UI and not alienate our users. Sure, there may have been two approaches: a radical redesign and an incremental change with every future release. We think that the right approach for us lies in between with one special ingredient added to the mix: understanding what our users want and how they use Zabbix. We believe this approach will fundamentally improve the quality of the interface we ship with our product

Staying Ahead of the Storm with Trend Prediction

Let’s imagine you fancy a walk in a park. You look out of the window – it’s a lovely sunny day, the skies are clear, birds are flying high… So you dress up and head to the park. Halfway to the park the wind starts to blow, the sky becomes overcast. At this point you start to regret that you have not taken an umbrella with you. You have to turn around and get back home as fast as you can, but at this point you have already no chance to stay dry… Where have you missed your step? You did not check the weather forecast before you left!
