 Description   

I upgraded from Zabbix 1.8.6 to 2.0.2 and did not experience any issues during the upgrade process.
I used Kodai Terashima's RPM packages from here: http://www.kodai74.net/packages/zabbix/zabbix-2.0/rhel/5/x86_64/

I noticed the new default templates were not present, so after searching the forums I found them here:
https://zabbix.org/wiki/Zabbix_Templates/Official_Templates#Zabbix_2.0.0

I was able to import all the App and SNMP templates successfully, however importing the OS templates fail (I have tried Linux, Windows, Mac OS X, and OpenBSD).

Here is the error I get when importing "Template OS Windows":

Created: Application "Zabbix agent" on "Template OS Windows".

Cannot implode expression "".

The last three error lines are the same when importing other OS templates. I also get the same error when importing a user-created NetApp template from here: http://www.zabbix.com/forum/showthread.php?t=26466

I don't see any obvious errors in zabbix_server.log or Apache error_log

could you please try with latest 2.0 svn head (or development snapshot) ? those templates seem to import just fine for me

Comment by Aaron Smart [ 2012 Aug 17 ]

I'm sorry I haven't a clue about svn and don't see anything newer than 2.0.2 on the SourceForge page. What do I do?

Comment by richlv [ 2012 Aug 17 ]

you can read about nightly builds and/or svn at https://zabbix.org/wiki/Get_Zabbix

OK I tried 2.0.3rc1 revision 29617 and get the same error but with different line references:

Undefined index: expression [api/classes/CTriggerPrototype.php:1151]
Undefined index: expression [api/classes/CTriggerPrototype.php:1153]
Cannot implode expression "".
