Line 290: − + − Zabbix agent is a very small daemon which will gather informations about the host being monitored, and report it to one or several server(s) (or proxy(s)).+ − 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). − *In passive mode, the server will connect to the agent (on port 10050 by default). − − Please read Chap. 2.3.4.ZABBIX Agent page 39 and Chap. 3.3.ZABBIX Agent (UNIX, standalone daemon) of the manual for more informations on Zabbix agent. − − ===== Installation ===== − − to install Zabbix agent, just use yum: − yum --enablerepo=smecontribs install smeserver-zabbix-agent − − − This package will download at least the following dependencies: − *zabbix (very small package with just common directories used by all zabbix components) − *zabbix-agent (the agent) − *smeserver-remoteuseraccess: this contrib is needed because it provides needed templates metadata for /etc/sudoers. − − ===== DB parameters ===== − − Here's the list of available DB parameters for zabbix-agent service on SME: − *'''RemoteCommands''': (enabled|disabled). If you want to enable remote commands on zabbix agent (you should read the zabbix documentation). Please, be aware that there're security implications if you enable it. The default is disabled − *'''ServerPort''': port to contact the server when running in active mode. Default to 10051 − *'''Servers''': List of servers (or proxy), separated by commas, to which send informations. The first one may be used for active checks, the others are only for passive mode − *'''TCPPort''': TCP port on which the agent will listen if passive mode is enabled − *'''access''': (public|private) If you want to open the agent on the public interface (only useful if passive is enabled).

For each of this check, you should add a new item with the name of the check as the key. − 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. − − Please, read chapter 4.11.User Parameters page 119 of the manual to have more informations on how UserParameters works. − − *External IP: − **'''ip.external''': Return the real external IP address. − − *Incoming mails statistics: − − {{Note box|Since version 0.1-28 of smeserver-zabbix-agent, the keys to retrieve emails statistics has changed.

*php-bcmath (smeserver-zabbix-server only): if you have the standard php4 packages, it should be ok. If you have upgraded to php5 from centosplus repo, you should manually install php-bcmath package
*php>=5.4 for zabbix server only, hence you will need to first install smeserver-php-scl on SME9 and set php54 or higher as default php version

==== 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.

===== Installation=====
<tabs container=""><tab name="SME 10">
to install zabbix 4.4
yum install smeserver-extrarepositories-zabbix -y
db yum_repositories setprop zabbix44 status enabled
signal-event yum-modify
yum install smeserver-zabbix-server --enablerepo=smecontribs
<br />
the following version are available :
zabbix42 zabbix44 zabbix45 zabbix50 zabbix51 zabbix52 zabbix53
===== Installation =====
Zabbix is not provided as server on Rhel 7 for version 5.1 and up. This is because of base php version, which could be worked around using php-fpm, but would also need us to build it.
install zabbix 50 server
yum install smeserver-extrarepositories-zabbix -y
db yum_repositories setprop zabbix50 status enabled
db yum_repositories setprop zabbix50-frontend status enabled
expand-template /etc/yum.smerepos.d/sme-base.repo
yum install smeserver-zabbix-server-z50 --enablerepo=smecontribs
</tab>
<tab name="SME 9">
First enable the needed repo: Firewall service and REMI
{{:Fws}}
{{:Remi-safe}}
signal-event yum-modify
to install Zabbix server, just use yum:
to install Zabbix server, just use yum:
yum --enablerepo=smecontribs 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.
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
config setprop php54 PhpModule enabled #replace here with php55 or php56 if you have other needs
signal-event php-update
then you will have to either tweak the default configuration as explain in next step or just issue :
signal-event zabbix-server-update
</tab>
</tabs>
then go to your web interface : https://yourserveradress/zabbix
===== DB Parameters =====
===== DB Parameters =====
Here's the list of available DB parameters for zabbix-server service on SME:
Here's the list of available DB parameters for zabbix-server service on SME:
*'''AdminPassword''': A random password is generated during the installation for Admin user. Replace the default weak zabbix password upon install.
*'''DbName''': The name of the database where everything is stored. Default is 'zabbixdb'
*'''DbName''': The name of the database where everything is stored. Default is 'zabbixdb'
*'''DbPassword''': The password of the database. A random password is generated during the installation
*'''DbPassword''': The password of the database. A random password is generated during the installation
*'''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. }}

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.

*'''Template_icmp''': will configure two items to check if the server is alive, and measure the latency. It also provides latency graphs and some triggers (if latency is too high, if host is down since more than 5min and if hosts is down for more than 1 hour)

=== Upgrading 4.4 to 5.0 ===
see this page https://www.zabbix.com/documentation/5.0/en/manual/installation/upgrade_notes_500. Mostly you will need to
* migrate your db from mariadb 5.5 to mariadb 10.5 with its user if not already done
* fix the row format to dynamic<syntaxhighlight lang="bash">
echo "USE $(config getprop zabbix-server DbName); alter table hosts row_format = dynamic; "|mysql105
</syntaxhighlight>
* fix ENGINE if forgotten before (y'''ou better doing it before importing it''', converting the history table could take days (yes days not hours)

cat /usr/share/doc/zabbix-server-mysql-5.0.30/double.sql |mysql105 `config getprop zabbix-server DbName`
</syntaxhighlight>

=== Migrate DB from mariadb 5.5. to mariadb 10.5 ===
