Zabbix 2.2 features, part 5 – Better value mapping

Value mapping is a neat, little feature in Zabbix that allows to see what a numeric code actually means. Well, what did that mean? For example, a UPS device might return “2”, which means “all is OK”, and “3”, which means “battery low”. There will be many different devices with different numeric codes, so remembering what they all mean is nearly impossible. Value mapping will show a human readable description, but the raw value will still follow in the parentheses – for example, Normal (2).

Until Zabbix 2.2, this was only supported for integers. Zabbix 2.2 will allow to configure value mapping also for decimal and string values.

Newly documented APIs

We’ve recently published the documentation for some of the APIs that have been introduced in 2.0 but had not been covered in the manual at all. If you are a Zabbix expert, you’re probably already aware of their existence, but if you don’t know your way around the source code, you might have missed them. Anyway, you can now familiarize yourself with six useful APIs for maintaining your Zabbix configuration.

Zabbix 2.2 features, part 4 – HTTP proxy for web monitoring

Having explored two other improvements to the built-in web monitoring – ability to template it and change retry count – let’s take a look at another one. Until Zabbix 2.2, it was not possible to set HTTP proxy for web monitoring… well, that’s not entirely true – with a hack one could set HTTP proxy for the whole Zabbix server (or, since Zabbix 2.0, Zabbix proxy), but there was no way to set it per web scenario. Zabbix 2.2 will provide such a feature.

“Why on earth was I not notified?!”

“Why on earth was I not notified?!” — ever heard that question from a fellow worker? Setting up notifications can be a challenge — and not only for beginners. Normally, debugging such cases is cumbersome, complex and requires a good understanding of how Zabbix works. Were you ever asked for a list of people who would be notified on some event? It’s hard to tell, until the event actually happens. Or at least it used to:

The Action Simulator tries to relieve you from these problems and make you and your co-workers happy again.

Zabbix 2.2 features, part 2 – Templated web monitoring

Continuing with the series on upcoming Zabbix 2.2, the second feature we will look at will be related to the built-in web monitoring that has been available in Zabbix for quite some time already. One problem some users faced – there was no way to use the extensive Zabbix templating system for web monitoring. This was not an issue if all we wanted to monitor were standard websites, but as soon as there would be a large amount of identical webservers, one would have to either do a lot of manual configuration or some scripting via the Zabbix API. Zabbix 2.2 will greatly simplify this by providing templatable web monitoring.

Zabbix 2.2 features, part 1 – Automatic database upgrading

Zabbix currently is at version 2.0, and this version took quite a long time to get out – almost 2 and a half years. Of course, all that wait was not in vain – Zabbix 2.0 provided a huge amount of new features. It did mean that you and me had to wait for quite some time before benefiting from those features, though, so there will be an effort to make Zabbix 2.2 happen sooner. Let’s start to look at the improvements Zabbix 2.2 will provide – and let’s start with the one that everybody upgrading will notice – automated database schema upgrades.

API versioning

The 2.0.4 release contains a lot of improvements so one tiny change may have passed unnoticed: the version of the API has been bumped to 2.0.4 as well. Indeed, that’s one small change in the code, but a huge decision for the Zabbix developers team. The API version has remained on 1.4 since the release of 2.0, but finally we’ve developed a versioning that will suite our needs.
