Zabbix trapper value is not received if item is created directly on host

[pzn]

Using Zabbix 6.0.13

Steps to reproduce:

• run a shell script which executes every 10 seconds: zabbix_sender -z 127.0.0.1 -s tryhost -k trykey -o 12345
• create host "tryhost"
• inside the host config, create item "tryitem" type "Zabbix trapper" key "trykey" number(unsigned)
• wait a minute. You will notice that no data appears in "latest data"
• I think the steps above should work, however they don't
• delete the created item
• create a new template "trytemplate", inside the template create item "tryitem" type "Zabbix trapper" key "trykey" number(unsigned)
• edit the host and link it to the template "trytemplate"
• wait a minute. Now data appears in "latest data"

Am I doing something wrong? Should items always be inside templates? I notice this only for "Zabbix trapper" type. I'm a Zabbix newbie, sorry for any misunderstanding in reading the docs :-)

Thanks,
Pedro

Should items always be inside templates?

No, items can be one-offs, they are not required to be part of a template.

Is this happening because of the warning in the docs about about waiting 60 seconds after creating the item before sending any data? https://www.zabbix.com/documentation...mtypes/trapper

Thanks Tim, you got right to the point! I tested it again with a wait time >60s and all was OK. I missed that "60 seconds warning". Sorry for the "RTFM" miss.
