Removing unfinished translations

Zabbix frontend is translated in many languages. For some, the coverage is great – 2.0.7 has been 100% translated in 9 languages. For some other translations the coverage is not that great… In preparation for Zabbix 2.2, there is a plan to remove translations below some threshold.

Zabbix virtual appliance moving to 64bit

Zabbix virtual appliance has been available for quite a long time now. It includes Zabbix server, agent and frontend, and everything is working out of the box. So far it has always been available in 32bit mode, to make it run on as wide range of platforms as possible.

With the new Zabbix 2.0.8 release, we are moving to 64bit platform. We hope that this won’t make it not working for anybody.

Additionally, this release of the appliance includes an example web monitoring scenario, along with some other minor changes to the default Zabbix configuration. That should make it a bit easier to explore those features – why not take a look at a working example and learn from it?

The appliance is available in 9 different formats, which should be enough for everybody. Head on to the download section and try it out.

Maps for the lazy

Creating complex maps is a time-consuming job. Actually, even designing a rather small map of 25 elements can take you an hour. That’s time you rather want to spend on something useful or fun, unless you’ve got a fetish for repetitive work. All we need to automate this task, is a network/graph library like Networkx and the Zabbix API.

Efficient synchronization of proxy configuration in Zabbix 2.0.7

Until Zabbix 2.0.7 proxies used a simple algorithm for their configuration synchronization – overwriting the old configuration with a new one. Even unchanged records were updated. It produced a lot of SQL updates even when there were no changes in configuration.

It worked good enough until one user wanted to synchronize a heavy loaded proxy (800 hosts, 120 000 items, 2000 NVPS) configuration every 7 minutes (see the graph).

The synchronization was taking about 2-3 minutes, produced more than 5000 updates per second and caused a heavy impact on performance of other Zabbix processes by blocking the hosts table. During this time poller processes could not update host status data.

In Zabbix 2.0.7 the synchronization aims to generate a minimum number of SQL queries by doing more work in the Zabbix proxy itself. The old configuration is read into memory and compared with the new configuration, record by record. If corresponding records exist in both old and new configurations every field is compared to find out differences. If all fields match, no update is necessary. If a few fields differ an SQL update statement is composed only for those fields.

Tests show that a configuration with 500 hosts and 600 000 items can be synchronized in ~11 seconds if there are few or no changes (not counting ~14 sec for getting 63 MBytes of configuration data from master server). That is 5 times faster than before (depends on the number of items).

After upgrading to Zabbix 2.0.7 the synchronization produces no updates if configuration is not changed as shown in the graph. The main improvement is less blocking of tables and shorter waiting times for other processes.

Translating Zabbix 2.2

The Zabbix 2.0 translation team has done a great job, but there’s something else coming closer… no promises, but Zabbix 2.2 will come out one day :)

With lots of new features and improvements, translatable strings have changed significantly, too. Even for languages that are in great shape in 2.0, things don’t look that great in 2.2 – yet.

Scalable Zabbix – Lessons on hitting 9400 NVPS

Also in Russian: эта статья доступна и на русском языке.

One of the questions for those of us that use Zabbix on a large scale is “Just how much data can Zabbix ingest before it blows up spectacularly?” Some of the work I’ve been doing lately revolves around that question. I have an extremely large environment (around 32000+ devices) that could potentially be monitored entirely by Zabbix in the future. There is a thread in the Zabbix forums where some people have discussed ideas for large environments, but unfortunately, I have not been able to find a thorough list of ways to run large environments. I intend to show how I set up my environment to handle a large influx of data. To give an idea of what I’m talking about, here are some of my current environment stats:

Zabbix 2.2 features, part 11 – SNMP monitoring improvements

Zabbix offers a lot of methods for data gathering, including SNMP. SNMP has been a popular protocol for many years and probably will stay that way – it’s used on routers, switches, UPS devices, storage arrays and lots of other devices.  Zabbix 2.2 will improve the existing SNMP support in several ways.
