Item tag filter not working properly after upgrade 4.3.0

[leonanu]

Can not get network interfaces bits send/received metrics after upgrade 4.3.0

Zabbix Ver: 6.2.7
Grafana Ver: 9.3.8/9.3.11

Could you explain it a bit? What's a query you have? What do you mean cannot get metric? In the list of metrics or the time series data?

[leonanu]

The "Item" shows nothing. But rollback to 4.2.10 everything goes well.

[alexanderzobnin]

Are you sure item tag is right? You can delete tag and see if you can get interface names in the items.

I have the same problem after update, not only with interfaces - a lot of tags shows empty items, for example 'Application: Filesystem' from linux, none of Exchange metrics shows etc. Everything was fine before update and zabbix wasnt touched. And i didn't figured out yet how to rollback to older plugin version in docker.

Note: If you need to specify the version of a plugin, then you can add it to the GF_INSTALL_PLUGINS environment variable. Otherwise, the latest is used. For example: -e "GF_INSTALL_PLUGINS=grafana-clock-panel 1.0.1,grafana-simple-json-datasource 1.3.5".

Hmm, that's strange. Do that tags exist in zabbix? Zabbix migrated applications to item tags, so maybe something happened here. Could you also clarify, do you see graphs on the dashboards? Or it both do not work - metrics list and graphs?

[Angrik]

Both not working - metrics list is empty thus 'no data' in graphs. Everything is fine and same in Zabbix, as it was 2 days ago.

[alexanderzobnin]

Ok, got it, will try to investigate.

[alexanderzobnin]

Confirmed, I have the same issue.

[alexanderzobnin]

I think the problem is in the wrong regex for tags. It does not handle properly spaces in tag value.

[alexanderzobnin]

@Angrik Can you check it again and tell me if issue is only related to the tags with spaces in the value, like Application: Network interfaces? I fixed it, but want to double check if I found root cause correctly.

[Angrik]

Yeah, seems about right. NO spaces:

With spaces empty list:
