Storing images in the Zabbix database

The encoding, database and the dog

Zabbix provides a network map feature, where images may represent triggers, hosts, host groups etc. They may show current status, problem count and lots of other data. There are some default images that may be used in the maps, and users may also upload their own. This uploading has been a problem in the past.

Reloading configuration cache

Zabbix daemons use various approaches to improve performance. One such measure, introduced in Zabbix 1.8, is configuration cache. It resulted in massive performance improvements (up to 10 times), mostly because of a significantly reduced database access (that we looked at in previous blog posts). This cache slightly changes how Zabbix operates, though, and can introduce some delays in configuration information processing. Zabbix 1.8.6 provides a new feature to help with configuration cache management. Continue reading “Reloading configuration cache”

Monitoring how busy Zabbix processes are

In the past, quite often Zabbix users have been puzzled regarding some server tuning parameters – for example, how many pollers do they need? It was usually determined based on experience, testing and a bit of guesstimating. No more fuzzy attempts – get hard facts with Zabbix 1.8.5.

Zabbix Source Code Trivia

The development of a monitoring solution, now called Zabbix, started way back in 1999. From the functional perspective, Zabbix is much more capable now than it was 11 years ago. However, is it possible that some of this functionality is still backed by code from those ancient times? How did the source code change over the years? In this article, we will take a look at how the software developed over time source code-wise.
