Processing with zabbix_sender ok but sending to Server Zabbix ko #22

Open Neo914 opened 2 months ago

Neo914 commented 2 months ago

Hello I have a problem of the same type I have a Zabbix server proxy and a Zabbix main server, the latter monitoring the Zabbix proxy. From the Zabbix proxy I have the Python script that is run to explore my Dell Unity and upload all the discovery elements in my Zabbix but I have a problem to remount the elements in Zabbix HMI.

root@deb:/usr/lib/zabbix/externalscripts# python3 unity_get_state.py --api_ip ... --api_port 443 --api_user ** --api_password * --storage_name DellEMC_unity --discovery 1 root@deb:/usr/lib/zabbix/externalscripts# python3 unity_get_state.py --api_ip ...* --api_port 443 --api_user --api_password ***** --storage_name DellEMC_unity --status 1 root@deb:/usr/lib/zabbix/externalscripts#

in the log unity_state.log I don't have an error

2024-07-09 11:41:07,751 - unity_logger - INFO - Connection established 2024-07-09 11:41:12,247 - unity_logger - INFO - Logout successful 2024-07-09 11:41:35,916 - unity_logger - INFO - Connection established 2024-07-09 11:41:40,324 - unity_logger - INFO - Logout successful 2024-07-09 11:41:50,849 - unity_logger - INFO - Connection established 2024-07-09 11:41:55,705 - unity_logger - INFO - Logout successful

on the other hand when I do the tests manually

root@deb:/usr/bin# zabbix_sender -z server_zabbix -p 10051 -s "DellEMC_unity" -k "health.disk.[{#ID}] " -o 4 -vv zabbix_sender [4022880]: DEBUG: In connect_to_server() [server_zabbix]:10051 [timeout:60, connection timeout:3] zabbix_sender [4022880]: DEBUG: In is_ip4() ip:'...**' zabbix_sender [4022880]: DEBUG: End of is_ip4():SUCCEED zabbix_sender [4022880]: DEBUG: answer [{"response":"success","info":"processed: 0; failed: 1; total: 1; seconds spent: 0.000019"}] Response from "server_zabbix:10051": "processed: 0; failed: 1; total: 1; seconds spent: 0.000019" sent: 1; skipped: 0; total: 1 root@deb:/usr/bin#

Can you help me figure out what's wrong?

For information I use the EMC Unity REST-API v3 template

But sending to zabbix I don't have to report data because I have a return code:2

Here is an example of a Discovry Rule

And Item prototype

Can you please help me to report the data value of each element discovered in Zabbix?
