Solution: Incorrect key format 'key_name[param1,param2,...]'

[Marcos Cabrera]

Hi,

After working hard with aggregation simple ckecks, I have discovered one way to solve this common problem.

Finally, I managed to create the following Zabbix Aggregate Item: grpsum('iTarifas_Planas','B','last','0')
iTarifas_Planas: Host group.
B: Item key.
last: Item func.
0: parameter

The problem was with the regular expression. Zabbix looks the item you enter, and compares it with some regular expressions. Debugging the problem I have seen that it's defined in the following file: include/defines.inc.php

There you can see: define('ZBX_EREG_ITEM_KEY_FORMAT', '('.ZBX_EREG_INTERNAL_NAMES.'(\('.ZBX
_EREG_PARAMS.'\)){0,1})');

In the original file, you will see some "[]", just replace them with "()", and it should works.

Good luck.

I've got the same issue on 1.8.2
Replace line ~600 in include/defines.inc.php beginning with

define('ZBX_PREG_KEY_NAME'

, to:

define('ZBX_PREG_KEY_NAME', '([0-9a-zA-Z_\.\-\:\ ,]+)'); /* !!! Don't forget sync code with C !!! */

This regular expression ([0-9a-zA-Z_\.\-\:\ ,]+) is not exactly correct. Right now it prevents "spaces" from the key names in 1.6 you could have keys with spaces in the names.
Is there a reason why spaces should not be supported anymore? If not then the expression should be:
([ 0-9a-zA-Z_\.\-\:\ ,]+)

Thanks,
Robert

Failure to support keys with spaces is causing difficulty in migrating from 1.6.x. There are thousands of spaces in the key names of 1.6x templates.
