Bug (1.8.2) when linking templates with dependencies

[spblue]

Since version 1.8 of Zabbix, we've had problems linking templates to hosts. We thought it was fixed in 1.8.2 but it's still there. Basically, when you have a template that has a trigger that is dependant on another template, you cannot link it to a host. Example with two templates:

Template A (Server)
Trigger : Server is down
Dependency : Template B trigger Switch is down

Template B (Switch)
Trigger : Switch is down

If you try to add Template A to a host, you get an error. You have to manually remove the dependency on Template A, then re-add it afterwards. This is extremely time consuming. Is there any workaround?

Alexei,

Can I get some feedback regarding this? Should I submit this bug officially somewhere else? We'd really like this acknowledged because we are monitoring thousands of hosts using templates depending on other templates and it's a showstopper for us. I understand it might not be a very high priority for you, but can you at least confirm that you're creating a bug track for it?

I have the same problem, and I'm very interested in resolving it.

I seem to have a similar problem, I described it on http://www.zabbix.com/forum/showthread.php?t=17337. I think it indeed has to do with dependencies, but I have the same problem just linking to blank templates with each other.

I confirm that this problem is also present in 1.8.3.

Perhaps some feedback from ZABBIX Support? Could you confirm this is probably a bug, so we can submit it, and that we're not overlooking something?

Thanks

What I've noticed is when you use discovery and setup the appropriate actions to add these host templates (and groups, etc...), you don't have this template/dependency issue (its a GUI issue). You do however, have a problem when you go to modify a host, but if you have cookie cutter systems, it shouldn't be a big deal to setup actions to cover all types of hosts.

If you don't use discovery, then you can look at the API. There might be something there you could use until this gets fixed. I used the API to import a couple hundred URLs (with triggers [w/deps], and graphs). Here is my triggers import (please don't mock, I'm not a php coder ):
