    Reconnecting a Kubernetes cluster to Zabbix

    I used to monitor my K8S cluster in Zabbix before. Later, I removed all the hosts in Zabbix that were linked to this cluster. Now I want to set up monitoring again using the Helm repo. I’ve noticed that data is flowing from the cluster to Zabbix, but no additional hosts are being discovered in Zabbix.

    I ran a test: I added a different test cluster to Zabbix. That cluster had never been monitored before. In this case, Zabbix did detect and add the additional hosts.

    I suspect that Zabbix still remembers the previous hosts it had discovered before, and now it doesn’t want to add them again. Does anyone have an idea how to solve this issue?

    I’m using: Zabbix 7.0.17 and the Helm repo: https://cdn.zabbix.com/zabbix/integr...etes-helm/7.0/
