Resolution: Cannot Reproduce
Steps to reproduce:
- deploy Galera cluster on 3 nodes (Master-Master)
- run Zabbix Proxy as a container with the DB server as one of the nodes (or it can be a virtual IP using haproxy)
- check data sender process : ps -ef | grep "data sender"
when increasing debug level to 5, the following logs are repeated:
221:20211104:131507.233 proxy_get_history_data() 2 record(s) missing. Waiting 0.100000 sec, retrying.
the function that fails is proxy_get_history_data.
due to this, the Proxy fails to send data fast enough. so the data will be stuck in the queue for hours or even days
to have data sent in mili seconds.
data sender process not 100% busy
