Multiple Templates for one Host - Problem

[brandy]

Hi,

i use zabbix 1.4 and try to link 2 templates to one host. the first one, is the standard solaris template. the second one is a snmp based template.

if i try to link the snmp template to the host, i get a:

[ERROR: Conflict between selected templates]

Can anyone help me?

cheers brandy

Now it works. But i need to delete the application link from the snmp template to made it work. Without the application link in the second (snmp) template it works.

But if i add the second template on the host i lost all my application links from the solaris template.

Is this a bug?


* Application 'uxapp01:Availability' deleted
* Application 'uxapp01:CPU' deleted
* Application 'uxapp01:Filesystem' deleted
* Application 'uxapp01:General' deleted
* Application 'uxapp01:Integrity' deleted
* Application 'uxapp01:Log files' deleted
* Application 'uxapp01:Memory' deleted
* Application 'uxapp01:Network' deleted
* Application 'uxapp01:OS' deleted
* Application 'uxapp01:Performance' deleted
* Application 'uxapp01:Processes' deleted
* Application 'uxapp01:Services' deleted
* Added new item uxapp01:jvmMemoryHeapFree
* Added new item uxapp01:jvmMemoryHeapMax
* Added new item uxapp01:jvmThreadCount

Yes, it looks like a bug, however I cannot confirm it yet.

[brandy]

try the following steps to reproduce it:

1.) create a host with the solaris template
2.) create a new template and create applications for it.
3.) link items in the new template to the applications.
4.) try to add the new template to the host with the existing solaris template

it should give you the linking conflict error.

if you need any screenshots or information, don't hesidate to write me!

I can confirm this one. The application links work when you link a template to a host, but if you link a template where one is already linked, the previous application definitions disappear.

I have had to unlink all templates to a host and link them back all at the same time to get the applications to assign correctly.

The fix (patch) is attached.

patch on 1.4.1

Did you apply this fix to 1.4.1? I try applying the patch and it gives me a fail at the second hunk at 895. (hosts.inc.php.rej)

Thanks.

[Alexei]

The patch is already included into 1.4.1. No need to re-apply it.

[btriem]

But I upgraded to 1.4.1 and am still having this same problem. Something I need to know? Rebuild host entry? Remove and add templates?

Thanks

i am also having this problem in 1.4.1...

I too had this problem. I verified that the patch was added to 1.4.1 (it is).

This is a hack so I don't know what I am breaking here, but I changed the frontend code and it allowed me to link multiple templates to a host, and it is actively monitoring the items in each template, so it looks like it is working.

edit popup.php:

change:

                if(!validate_templates(array_keys($templates)))
                {
                      show_error_message('Conflict between selected templates');
                }
                elseif(isset($_REQUEST['select']))
                {

to:

                //if(!validate_templates(array_keys($templates)))
                //{
                //      show_error_message('Conflict between selected templates');
                //}
                if(isset($_REQUEST['select']))
                {

I'll let you guys know if I see any problems with that, which I'd imagine there would be in a few situations, it seems like the function validate_templates needs some reworking.

[Alexei]

This patch is absolutely incorrect. Apply it if you'd like to get all sorts of problems at some point later.

Care to elaborate on the problem so we can write a patch that truely fixes the issue? Or maybe a better description as to what the conflict is so we can correct it. I didnt see any conflicts in my templates (that I know of)

[Alexei]

There are two possible conflicts between templates linked to a host and ZABBIX checks that:

- templates contain items having the same keys
- templates contain applications having the same names

Otherwise new template can be linked to a host.

[1.4.2] Conflict between selected templates

Hi,

I linked a host to 3 templates: windows, dell poweredge and dell open manage. Everything worked fine.

But, the Dell items were not tied with an application. So I created one application called "Dell" and linked it with dell poweredge template. Them I created another application "Dell" and linked it with dell open manage.

So, into the monitoring screen, everything was grouped under "Dell".

But when I tried to include another host, I received the Conflict between selected templates error message.

I thought that the problem was related due to the fact that I used the same name. So I deleted one application (the one that was linked with the power edge template).

After that, the error was gone, but the "Dell" application doesn't work anymore. All my items appears as "others"... I tried to update the items, but it seems that I'm not able to use it anymore.

Seems that zabbix is reffering to applications as names, not codes.

Att.,

Bob
