Zabbix Agent 2 on Windows and active checks

[guille.rodriguez]

Hi, I currently have a Zabbix 6.0.5 LTS server mounted on a VPS in the cloud.

I want to monitor Windows systems where I have installed the Zabbix Agent 2 6.0.5 client. Everything works correctly if I use the passive mode (opening ports in the firewall).

However, when I use the active mode, although the data arrives, it does not arrive in the time configured.

For example, system.uname is configured every 5 minutes, but sometimes it takes 1h to receive the information.



Zabbix Agent 2 Configuration its

LogFile=C:\Program Files\Zabbix Agent 2\zabbix_agent2.log
Server=zbx.myvps.com
ServerActive=zbx.myvps.com
HostnameItem=system.hostname
BufferSend=3600
EnablePersistentBuffer=1
PersistentBufferPeriod=30d
PersistentBufferFile=C:\Program Files\Zabbix Agent 2\zabbix_agent2.db
Timeout=30
Include=C:\Program Files\Zabbix Agent 2\zabbix_agent2.d\
Include=C:\Program Files\Zabbix Agent 2\zabbix_agent2.conf.d\*.conf
ControlSocket=\\.\pipe\agent.sock
AllowKey=system.run[*]
Plugins.SystemRun.LogRemoteCommands=1
ForceActiveChecksOnStart=1
Include=.\zabbix_agent2.d\plugins.d\*.conf

When I check Zabbix Server Queue

Edit: After few hours I see that the problem could be BufferSend=3600, now I set BufferSend=5 , but the problem isn't solved. I restart service in Windows machine and also restart Zabbix-Server

As you can see in last image, (ignore Dell and Toshiba) , GR-LEGION don't send this item in last 13 min. At the end of this edit, 20 min .

After some research, reading that post https://www.zabbix.com/forum/zabbix-...-snmp-requests

I found that in Active Agent there's a preprocessing with "Discard unchanged with heartbeat" with value 1d.

After deleting this preprocessing, the data gets in time (1 min).

For some reason, in Passive Agent template I deleted this preprocessing time ago...

Please any help? Issue still

Please check the log files. There should be information in the log files that tells you why the agent is trying to send and cannot.

Thanks for answer Atsushi,

I check the log and Agent in sending info, and if I check log in Zabbix Server , the data is received, but some reason isn't see in frontend... only if I restart Zabbix Server the data is printed.

Data in passive mode is printed at time it checks
