Environment:

In our set up, we have a template (company-linux-host), that is linked to:

• Linux OS Template
• SSH Service Template (checks SSH process is running)
• Docker Service Template (checks docker process is running)

We monitor web services, but their triggers are created on the hosts (since each host has is hosting a different web service).

Most of our web services run within docker containers. When the docker services is down, Zabbix sends notifications about the docker service being down, as well as the web service being down - which is unnecessary.

We should be able to make the web service trigger dependent on the docker service trigger, so that if Docker goes down, we only get a notification about that - not about both.

However, according to the Zabbix trigger dependency documentation, this is now allowed. I noticed that this feature was removed in an earlier version. It seems there would be more such use cases, where a system process (defined in a template, since it runs on all hosts) going down, would obviously cause services to go down, thereby creating a need for dependencies.

Notes:

• I tried to create this link through the API, but got the error cannot add depedency from a host to a template
• I could create the same dependency using the web UI
