Using zabbix_sender to send to multiple zabbix-servers

[ddb0faz]

Zabbix <> 2.4.8
OS <> Rhel 7.9
I'm migrating from standalone to virtual (VMware). I want to send data to both existing and new zabbix servers for a period of time before cutover.

My zabbix_agentd.conf file is configured as:

Server=zbxsvr01
ServerActive=zbxsvr01
Include=[path]/agentdconf.d/

In the agentdconf.d I have a file called [name].conf that contains

Server=zbxsvr01,zbxsvr02,zbxsvr03
ServerActive=zbxsvr01,zbxsvr02,zbxsvr03

I have a script that uses zabbix_sender to push data to the zabbix_server

[path2]/zabbix_sender -c [path2]/zabbix_agentd.conf -i filename

QUESTION <> Will this send data to ALL zabbix servers?

[ang3lwich]

I am wondering if a zabbix_proxy might be of use.

As far as I remember, if your client hosts have all zbxsvr(0X) in the conf file or in your case name.conf
it should send data easy peasy to all servers as you desire.

I read that zabbix proxy can't do that. Nothing though on a server where the agent is installed and you are using zabbix_sender to push data.

OPTIONS

-c, --config config-fileUse config-file. Zabbix sender reads server details from the agentd configuration file. By default Zabbix sender does not read any configuration file. Only parameters Hostname, ServerActive, SourceIP, TLSConnect, TLSCAFile, TLSCRLFile, TLSServerCertIssuer, TLSServerCertSubject, TLSCertFile, TLSKeyFile, TLSPSKIdentity and TLSPSKFile are supported. All addresses defined in the agent ServerActive configuration parameter are used for sending data. If sending of batch data fails to one address, the following batches are not sent to this address.

Guy's,

While setting up a new zabbix5 server, I modified my agent conf file and added my new server svrzbx5 to read:

Server=svrzbx4,svrzbx5
ServerActive=svrzbx4,svrzbx5

What I can tell you is that all servers ussing zabbix-sender on my network only manage first address.
In other words:

Server=svrzbx4,svrzbx5
ServerActive=svrzbx4,svrzbx5
Transmit to svrzbx4

Server=svrzbx5,svrzbx4
ServerActive=svrzbx5,svrzbx4
transmit to svrzbx5

the command line is:
zabbix_sender -c /etc/zabbix/zabbix_agentd.conf -k pg.db.dump[$DBNAME] -o $EXITPGDUMP > /dev/null

Tex74 , Hi.

In this case zabbix_sender will always read the first entry for zabbix server.

As stated in the docs (share above by cyber )

All addresses defined in the agent ServerActive configuration parameter are used for sending data. If sending of batch data fails to one address, the following batches are not sent to this address.

That's why it's responding like that.
If you want to use zabbix_sender with both of them, you can configure two remote commands to read the configuration file (with -c), and passing "-z <server4|5>".

Let me know if that helped.

Cheers,

Based on exactly, what you quoted from docs, it should send to both...
Is there anything in agents logfile about failures?
