Regular Expressions on trigger

[pedrobastos]

Hello,

I'm trying to make a trigger using regular expression to work on a log type item.

This is my trigger:

{router.pontonet.com:snmptrap["ifIndex[[rint:]]*: 5"].regexp("linkDown[[:ascii:]]*ifOperStatus[[rint:]]*1$")}=1

Using a online regular expression tester, it found matches however inside Zabbix nothing is found.

This is my server returning 0 matches:

22119:20140820:181231.428 In evaluate_function() function:'router.pontonet.com:snmptrap["ifIndex[[rint:]]*: 5"].regexp("linkDown[[:ascii:]]*ifOperStatus[[rint:]]*1$")'
22119:20140820:181231.428 In evaluate_STR()
22119:20140820:181231.428 In get_function_parameter_str() parameters:'"linkDown[[:ascii:]]*ifOperStatus[[rint:]]*1$"' Nparam:1
22119:20140820:181231.428 In substitute_simple_macros() data:'linkDown[[:ascii:]]*ifOperStatus[[rint:]]*1$'
22119:20140820:181231.428 get_function_parameter_str() value:'linkDown[[:ascii:]]*ifOperStatus[[rint:]]*1$'
22119:20140820:181231.428 End of get_function_parameter_str():SUCCEED
22119:20140820:181231.428 In zbx_vc_get_value_range() itemid:66495 value_type:2 seconds:0 count:1 timestamp:1408572746

22119:20140820:181231.429 End of zbx_evaluate_item_functions()

This is my item value:

Glad if you may help me.

Thanks in advance,
