The enterprise class monitoring solution for everyone

Today's topics

● Zabbix overview● We met 2 years ago – what's new?● Uncommon uses


2 years for Zabbix

● Zabbix 2.0 out in May● 13 maintenance releases of 1.8● 2 conferences and a branch in Japan


Zabbix – mature by now

● Developed since 1998● First public release in 2001● 12 years old next April


True open source

OpenCore


What's included

Integrated solution● Data retrieving● Historical data storage● Official web based frontend● Alerting, discovery● More


Components

Server

Database Frontend


Native agent


Choose the direction

Server

Active

PassiveRequest: CPU load

Response: 1.95

Request: List of checks

Response: CPU load, Diskspace...

Free diskspace on / : 13GB

CPU load : 4.32

Fan 5 RPM : 3524

CPU 1 temperature : 34


Agentless methods

● TCP checks● SNMP● IPMI● SSH, telnet


Advanced methods

● Calculated

Total – free = used

● Aggregate

Total free diskspace for all fileservers

Average qps for all database servers

5000qps 1000qps 9000qps

Aggregate value = 5000 qps


What's a problem?

● Extremely flexible problem conditions– Functions last, min, max, avg, delta etc

– Comparison, math, boolean logic

– Check multiple values across several hosts

● 6 severity levels


Templating

Template_MySQL MySQL server

Queries per second

{Template_MySQL:qps.avg(300)}>5000 {Server:qps.avg(300)}>5000

Queries per second


Low level discovery

● Agent – filesystems, network interfaces● SNMP tables (interfaces, anything)● Custom


Custom LLD data

{ "data":[ { "{#FSNAME}":"/sys", "{#FSTYPE}":"sysfs"}, { "{#FSNAME}":"/proc", "{#FSTYPE}":"proc" }, { "{#FSNAME}":"/", "{#FSTYPE}":"ext3" }, { "{#FSNAME}":"/home", "{#FSTYPE}":"ext3" }, ]}


LLD is awesome


It really is


Automatic inventory

● Hardware chassis details● CPU frequency, vendor, model...● PCI/USB device list● MAC addresses● Operating system name, architecture● Installed package list


Multi-homed hosts


Alerting

● E-mail● SMS● Jabber/XMPP

Extendability

● Run any command on the agent or server● Run any command in response to events● Feed timestamped data in Zabbix● No language restrictions


Scalability

● Server, proxy and agent are written in C● Server

– Real world installations with 40K-80K hosts and more

– Processing thousands of values every second

– ...or > 2 million values/checks every 5 minutes


Server improvements for 2.2

● Configurable amount of processes– Pollers

– Trappers

– ...

● In 2.2 - timers


Agent scalability

● Agent– Uses less than a megabyte of RAM (736K on

64bit; excluding shared libraries)


Performance improvements

● Server– More caching

– Actually, lots more caching

– Optimised database access



● Proxy– Data sending

– Long-term use



● Agent– Memory usage


Upgrade policies

● No database changes in one major release● All old agents supported● Automatic database upgrade coming in 2.2


Popularity

● Japan, Russia, Brazil...● Financial, ISP, government,

manufacturing...● Other open source projects


Uncommon uses

● Some examples back from 2011, first Zabbix conference in Riga


Monitoring users on IRC


Weather forecast

OpenStreetMap licence agreement


Serious bug


Zabbix is..

● Flexible● Scalable● Rapidly improved● True opensource
