Zabbix 6.0.15
CentOS Stream release 8
Afects Version did not have 6.0.15 as an option, so I chose 6.0.15rc2.

I have the same issue in RHEL 8.7 after upgrading from 6.0.14 to 6.015.  I downgraded back to 6.014 and the issue cleared.

It appears (atleast for me) the preprocessor rule "changes per second" is breaking my all the items that use it.  If I remove this rule from the item it then works as expected. 

Of course this is not a solution because we obviously need the changes per second preprocessor. I also noticed if I manually test an item for the first time I get no value reported. I click it again and it returns the value for the items with the "changes per second" preprocessor rule enabled. Items without that rule I am able to test successfully on the first attempt.

And now we have to wait a month? 

but everything works in version 6.4.1, which was released three days later than 6.0.15

We're working on a fix and aiming for a faster 6.0.16 release.

Thank's. 

How this is possible that with such a huge bug was merge to 6.0.15 after RC1 and RC2?
So many graph not working right now....
The QA department is on vacation ?

Thanks!

Available in versions:

• pre-6.0.16rc1 - 179d217c3a5

I hope faster means tomorrow. Entire infrastructure monitoring is broken!

we saw this bug on our production zabbix environment aswell, and indeed, rollback to 6.0.14 seems to solve it.

Small note for people that use a seperate proxy, this also has to be rolled back to 6.0.14 or it has the same issue with the preprocessing and you are missing values

Hello, were can I get the Debian (buster) package for the proxy in version 6.0.14? Thanks

https://repo.zabbix.com/zabbix/6.0/debian/pool/main/z/zabbix/

With my desktop (Linux Mint 21.1) at version 6.0.15 and my proxy (AlmaLinux 8) at version 6.0.15, I can query the net.if.in and net.if.out item normally.

When I run zabbix_get from proxy pro desktop it works normally.

When I run zabbix_get from server to another server (without proxy) it works normally.

Only the unfortunate server (Ubuntu 22.04) in version 6.0.15 cannot store.

How can i downgrade from 6.0.15 to 6.0.14 please?

I'm on Ubuntu 20.04, I did:

wget http://repo.zabbix.com/zabbix/6.0/ubuntu/pool/main/z/zabbix/zabbix-server-mysql_6.0.14-1%2Bubuntu20.04_amd64.deb

dpkg -i zabbix-server-mysql_6.0.14-1+ubuntu20.04_amd64.deb 

apt update 

 systemctl restart zabbix-server

That's what i needed. Thank you a lot.

User who updated to TimescaleDB 2.10 can't downgrade to Zabbix 6.0.14.
Please, release a 6.0.15-2 release to fix it.

livreacesso.pro you can use 6.0.14 and adjust in the Zabbix Server configuration file:

AllowUnsupportedDBVersions=1

Release of the 6.0.16 is planned this week.

https://www.zabbix.com/br/rn/rn6.0.16#:~:text=Fixed%20loss%20of%20preprocessing%20result%20when%20step%20with%20delta%20is%20used

Both 6.0.16 deb packages and docker containers are available since today, thanks for your work in speeding up the release, it was kind of critical.

After upgrading both server, proxies and clients to 6.0.16, I can see that some network metrics still don't appear, is there anything particular to make them collect again?

Still having this problem, when using 6.0.21

6.0.22 here, working well.
