Multiple Zabbix agent

[Matthieu]

Hello,

I try to have a 2 zabbix agent on a debian server because i want to monitor him with 2 differents zabbix server.

How can i make please?

(I managed on a windows server).

Thanks,

You would need to set up 2 separate zabbix_agentd.conf files.

In the second one, you'd set the ListenPort=10050 to ListenPort=10052 or ListenPort=10049.

Option 2 would be to have two IPs on the box and configure the ListenIP to be different in each file, instead of the port.

Then execute zabbix_agentd with the -c or --config option and point to the second file for the second agent.

Thanks untergeek for you reply. But i've a question:

If I execute zabbix_agentd -c /etc/zabbix/zabbix_agentd2.conf

(agent2.conf is my second zabbix config file)

The configuration of my first zabbix agent will be changed? (windows agent have -m parameter for multiple agent)

And with this added, should i modify /etc/services ?

[untergeek]

No, the config files are safe from alteration by the zabbix processes.

You can alter /etc/services, but that's only if you want to know what is running where. It's unnecessary for the ability to run zabbix.

[Matthieu]

Yeah it's good! Thanks very much untergeek

[Matthieu]

hummm it's not good...

I can't connect to my second zabbix agent.

When i try

telnet 192.168.0.210 10051

I have:

telnet: Unable to connect to remote host: Connection refused

and in my zabbix server:

error: Get value from agent failed: *** Cannot connect to [192.168.0.210]:11051 [Connection refused]

[untergeek]

agent1 on host1.example.com:10050 -> zabbix_server1.example.com:10051
agent2 on host1.example.com:11050 -> zabbix_server2.example.com:10051

You need to make sure that from host1 you can telnet to port 10051 on both zabbix servers. You also need to make sure that zabbix_server1 and zabbix_server2 can telnet to host1.example.com on both ports 10050 and 11050.

On top of that, when you create the host for host1.example.com on zabbix_server2, you need to make sure to assign the port to be 11050 in the host definition in the zabbix UI.

[Matthieu]

Sorry it's an error when i've copy my log. I use 11050 port.




I've solved my problem. I post the solution for have 2 agent in the same linux server:


You have the first zabbix-agent that running well


Copy zabbix agent config file:

cp /etc/zabbix/zabbix_agentd.conf /etc/zabbix/zabbix_agentd2.conf


Edit /etc/zabbix/zabbix_agentd2.conf

--------------------------------------------------------------------------------------------


####Ip Zabbix_Server

Server="ip_zabbix-server"

#### Hostname value must be different that hostname value in zabbix_agentd.conf
#### Hostname = Hostname on zabbix server

Hostname="name"

####Listen port must be different that Listenport value in zabbix_agentd.conf

ListenPort= "port_zabbix-server"


####Listen IP

ListenIP="ip_machine"


####Name of PID file

PidFile=/var/run/zabbix-agent/zabbix_agentd2.pid



--------------------------------------------------------------------------------------------


Create a second zabbix_agent processus:

cp /var/run/zabbix-agent/zabbix_agentd.pid /var/run/zabbix-agent/zabbix_agentd2.pid


chown zabbix /var/run/zabbix-agent/zabbix_agentd2.pid


Launch zabbix agent

zabbix_agentd -c /etc/zabbix/zabbix_agentd2.conf




It's good!!!

Not quite true:

### Option: Server
#       List of comma delimited IP addresses (or hostnames) of Zabbix servers.
#       No spaces allowed. First entry is used for receiving list of and sending active checks.
#       If IPv6 support is enabled then '127.0.0.1', '::127.0.0.1', '::ffff:127.0.0.1' are treated equally.

You only need two agents if you are using active mode to both servers. Otherwise it's active only to the first server in the list.

to expand on what nelsonab said, if you are using passive items, all you need is a single agent that allows connections from multiple ips. which means adding them all to the agentd config file "server" directive

may I ask, what's the correct syntax for this ?

Server=IP1,IP2

or ?

I want 2 zabbix servers to connect on 1 agent ... to have one host monitored by 2 zabbix srvrs ...

is there any other change required in .conf or ?

thanks so much in advance ...

[richlv]

as the configuration file comment confirms, that is the correct syntax
