duplicates ZBX-19565 Zabbix Agent 2 on Windows is not able... Closed
Team: Team A

 Description   

Steps to reproduce:

  1. Use Agent2. Create item with nonexistent service using key service.info (e.g. service.info["test",state])
  2. Click Test button and next Get value

Result:


See message "The specified service does not exist as an installed service." and missing value
Expected:
Documentation (Windows-specific item keys [Zabbix Documentation 5.0]) says that there should be 255 value for nonexistant services, but I get error. Monitored host is Windows Server 2019 x64 with Zabbix Agent 2 (version 5.0.9). Zabbix Server version is 5.0.9.

Additionally can you advise how to trigger action if on new Windows host there isn't specific service?

Agent2 is listening custom port 10060, classic agent is listening regular port 10050:

# zabbix_get -s 10.33.0.28 -p 10060 -k 'service.info[test,state]'
ZBX_NOTSUPPORTED: The specified service does not exist as an installed service.

# zabbix_get -s 10.33.0.28 -k 'service.info[test,state]'
255

Agent2 should behave the same way as classic agent, so should be fixed.

Unfortunately I can't confirm. On my Windows machines Zabbix Agent 2 service listens on 0.0.0.0:10050 (checked by 'netstat -nta'). Service has been installed using zabbix_agent2-5.0.9-windows-amd64-openssl.msi from Zabbix website.

$ zabbix_get -s A.B.C.D -p 10050 -k 'service.info[test,state]'
ZBX_NOTSUPPORTED: The specified service does not exist as an installed service.

$ zabbix_get -s A.B.C.D -p 10060 -k 'service.info[test,state]'
zabbix_get [1982345]: Get value error: cannot connect to [[A.B.C.D]:10060]: [111] Connection refused

$ zabbix_get -s A.B.C.D -k 'service.info[test,state]'
ZBX_NOTSUPPORTED: The specified service does not exist as an installed service.

Can I get 255 code using Agent2 or should I install classic agent also?

Comment by Oleksii Zagorskyi [ 2021 Apr 26 ]

Custom TCP port I used (10060) is not related to bug itself at all. I just installed both agents and had them running simultaneously.

If you will use so called classic agent (not Agent2) - it works correctly for the key.

It was fixed in 5.0.20: ZBX-19565

msl0, Would it be possible to try this version?

Sadly, this one was somehow missed and the real duplicate was created later. But since the issue was fixed there, closing as duplicate of ZBX-19565 . Feel free to re-open if you disagree.
