Upgrade to 6.2 - Data does not seem to be going into the database

[Kevin Penn]

Hi,
I have upgraded to 6.2 via 6 from 5.4.
The front end looks ok, and the proxies are connected and seem to be sending data
There is however no data in the graphs from post the upgrade (grafana also is not getting any data from zabbix)
the db is up as i can access it from dbeaver

Any ideas as to what could be wrong?

Check preprocessing item 'Discard unchanged with heartbeat'.

If theres thispreprocessing, change the time of heartbeat or disable this preprocessing and test

Hi, i have now resolved this - one of the proxies was refusing to work, but it seemed to be a backlog issue as it started back a few hours later
Many thanks for your help on this
