Add a Zabbix proxy to an existing Zabbix server

So; you have an existing and working Zabbix server and would like to add a Zabbix proxy server? Here are the steps:

Install zabbix-proxy

On a new host (likely in some remote network) install the software package zabbix-proxy:


yum install zabbix-proxy
chkconfig zabbix-proxy on

We'll need to configure it, but that's a later step.

Create a database

Another easy step, maybe you already have a database infrastructure on the remote network, otherwise you can always install a database server locally:


yum install mysql
/usr/bin/mysqladmin -u root password 'MyPassword'
chkconfig mysql on
service mysqld start
 
No matter where the database server is located, zabbix-proxy needs it's own database:


GRANT SELECT,INSERT,UPDATE,DELETE ON zabbix.* TO 'zabbix'@'localhost' identified by 'MyZabbixPassword';
 
The database schema also needs to be populated. That schema can be found from the zabbix source code package, in database/mysql/ .


mysql -u root -p zabbix < data.sql

Configure zabbix-proxy

There are a few items to configure in /etc/zabbix/zabbix_proxy.conf.
The Server should point to your existing Zabbix server.


Server=existing-zabbix-server.example.com
 
The Hostname should be set, and should match exactly on what you configure later in the existing Zabbix server webinterface.


Hostname=zabbix-proxy-01.example.com
 
You also need to configure the Zabbix proxy to be able to connect to the database:


DBHost=localhost
DBName=zabbix
DBUser=zabbix
DBPassword=MyZabbixPassword

Configure zabbix-server

This is a very easy step; go the the webinterface and click to:
Administration - DM
Click on Create Proxy
Fill in the name of the proxy, exactly like you set it on the proxy in /etc/zabbix/zabbix_proxy.conf under Hostname.

Start zabbix-proxy

service zabbix-proxy start
 
On the Zabbix server you should now see under Administation - DM that the "last seen" field is updated. (It might take a minute or so.)

Monitor a node with the zabbix-proxy

Now you may add hosts to zabbix that are monitored by that proxy. On the configuration of that host, select the newly configured proxy at "Monitored by proxy".
If you can't get the Zabbix proxy to be seen by the server, make sure that these ports are open:
Source Source port Destination Destination port Description
Zabbix proxy any Zabbix server 10051/tcp The Zabbix proxy sends the traffic to the Zabbix server over this port
Zabbix proxy any Zabbix hosts (agents) 10050/tcp The Zabbix proxy connects to monitored hosts on this port for "passive" items.
Zabbix hosts (agents) any Zabbix proxy 10051/tcp The Zabbix hosts connect to the Zabbix proxy for "active" items. 

Also check the logfile /var/log/zabbix_proxy.log on the Zabbix proxy.

CLEANING UP THE ZABBIX DATABASE

My Zabbix database size increased a lot in the last few months and since my disk was running out space, I decided to clean up the old events from the database. Looking at the database tables, the biggest one was  history_uint , which holds the items history data – over 400 millions of records and over 30 Gb of disk space before the clean up. Since deleting the old records from this table directly would be a very slow process, I decided to create a new table and insert the latest records from the  history_uint  table and then just replace the old table with a new one. Since this is not an offical procedure, use it at your own risk. Environment: Zabbix v2.2 MySql 5.1 – InnoDB with  innodb_file_per_table=ON Step 1 – Stop the Zabbix server Step 2 – Open your favourite MySQL client and create a new table CREATE TABLE  history_uint_new  LIKE  history_uint; Step 3 – Insert the latest records from the  history_uint  table to the  history_uint_new table First you need to de

Configuring DHCP Relay service on the FortiGate unit

Configuring DHCP Relay service on the FortiGate unit If the clients are configured to obtain a IP address using DHCP relay, configure the FortiGate server as below: To configure DHCP relay on the FortiGate unit   1. Go to System > Network > Interfaces and select Interface want to configure DHCP relay.   2. Enable DHCP Server in the interface and choose Advanced   3. For Mode, select Relay.   4. In Type select Regular.   5. Select OK.   6. If a router is installed between the FortiGate unit and the DHCP server, define a static route to the DHCP server. Note : Sometimes it is required to specify more than one DHCP relay IP, to allow for the coverage of additional LAN subnets. Although the Web Based Manager (GUI) does not provide an option to configure this, it is possible to set up to 8 IPs from the CLI.       config system interface             edit <REQUIRED_INTERFACE_HERE>               set dhcp-relay-ip <FIRST_IP> <SECOND_IP> ....<EIGHTH_IP&

WAN link load balancing

Hình ảnh
W A N link load balancing In the same way that incoming traffic can be load balanced, outgoing or WAN traffic can also be load balanced and for the same three reasons. 1 .  Reduce the places in the work flow where a single point of failure can bring the process to a halt. 2 .  Expand the capacity of the resources to handle the required workload. 3 .  Have it configured so that the process of balancing the workload is automatic. Often, it can be just as important for an organizations members to be able to access the Internet as it is for the denizens of the Internet to access the Web facing resources. There is now a  WA N Load Balancing  feature located in the  N e t w o r k  section of the GUI (“WAN LLB”). As part of the new WAN Load Balancing feature, the FortiOS 5.2  R ou t e r > Static > Settings  GUI page has been removed. WAN Load Balancing should be used instead of the 5.2  E C M P Load Balancing Method  settings. The 5.2  L i n k Health Monitor  definitions
