==== Server ====
==== Server ====
The server is the core component of Zabbix software. It uses one database (MySQL in this contrib) to store configuration, performance and integrity informations. The server can check network services with simple check (ICMP, TCP etc...) for agent-less monitoring, it can monitor network devices using SNMP and is also the central component to which agent report informations (agent can work in active, passive, or both mode). The server will also analyse all the informations and send alerts depending on very flexible triggers.

First enable the needed repo: Firewall service and REMI

to install Zabbix server, just use yum:
to install Zabbix server, just use yum:
yum --enablerepo=smecontribs,fws,remi-safe install smeserver-zabbix-server
yum --enablerepo=smecontribs,fws,remi-safe install smeserver-zabbix-server --exclude=smeserver-zabbix-proxy
NB: the --exclude=smeserver-zabbix-proxy is due to a conflict in late 2019 on SME9 as FWS started using zabbix from zabbix repo instead of building it. We will fix this for SME10 in few months.
then go to your server-manager to set php5.4 or higher as default php for your SME, or you will not be able to access to zabbix web gui, or just issue the following

*'''JabberPassword''': Password for the account (for "JabberAccount")
*'''JabberPassword''': Password for the account (for "JabberAccount")
*'''JabberTLS''': (enabled|disabled) Does your Jabber server requires TLS security
*'''JabberTLS''': (enabled|disabled) Does your Jabber server requires TLS security
{{Note box|The different Jabber settings above are not for the built-in jabber notification function (because I couldn't get it working as my server requires TLS and the built-in feature do not support it). But I've included a external script using sendxmpp to send the notification. You should have a media called 'xmpp' in zabbix administration. }}

Agents can run in active or passive mode (or both):
Agents can run in active or passive mode (or both):
*In active mode, the agent will make outgoing connection to the server (port 10051 by default).

===== Additional checks =====
Configuring the corresponding checks on the server can be quite long. You can have a look at the [http://sme.firewall-services.com/downloads/zabbix/zabbix_SME.zip templates] I use to monitor SME Servers. This archive contains some templates/items/graphs/triggers in XML format (exported from Zabbix). You can use the Import/Export functionality of Zabbix (Manual Chap. 8.XML IMPORT AND EXPORT page 154) to import it on your server.

You can also have a look at the configuration file /etc/zabbix/zabbix_agentd.conf to see the commands used to return the corresponding values. You'll also find for each UserParameter informations on how to create the corresponding item on the server.

==== Proxy ====
==== Proxy ====
Zabbix proxy is a lightweight daemon. It will act as a server for agents, will cache locally (in a mysql database) the informations, and send it to the server it belongs to. This is useful to monitor networks elements behind a firewall.
