Probleme with RegEXP and vfs.file.regexp

[Arnaud_35]

Hello fellow Zabbix users,
first of all i'd like to mention i'm not a Zabbix specialist at all, i have been using it for only one week and please forgive my english as i'm french.
I'm using Zabbix 2.2.2 version on a Ubuntu 14.04 system

I have been trying to use the vfs.file.regexp function to parse a .txt file which contain a number of values following the patern:
nameofvalue1 {value1}
nameofvalue2 {value2}
I'm using an online regexp tester and the zabbixagentd -t command line to verify my regexp.
My values are float type (execution time in microsecond).

My problem is that i can't get the item to properly return the value matching the regexp.

I have tried a lot of regular expressions syntax but most of the time i get a ZBX-NOTSUPPORTED when i test my item with zabbixagentd -t.

For example when i type this very global regexp just to see if i get a result(i'm escaping {} because command line doesn't use extended posix):

zabbix_agentd -t vfs.file.regexp[path/to/file,"test1 \{(.*)\}$",,,,]

i get the following result:

[s|nameofvalue1 {value1}] which is the whole line containing the float number i want to parse (value1).
So i read about the output mode of the vfs.file.regexp function and changed the command to:

zabbix_agentd -t vfs.file.regexp[path/to/file,"test1 \{(.*)\}$",,,,\1]

But now i get:

[s|1]

...And if i change the output mode to \2 i get [s|2] etc. I'm confused.
I tried a lot of syntax but the only results i get are either [s|ZBX-NOTSUPPORTED] or [s| ] or [s|thevalueofoutputmode]...

All i want to get is the value1 (22,2222222 for example) to be able to make a graph with it.
As i said i'm new to all of this(even ubuntu and regexp) and i'm probably doing something wrong so i apologize if the mistake seems obvious to you...

Thx in advance

I have the same issue (https://support.zabbix.com/browse/ZBX-9551).

Someone to help us ?

I tested these file and item key.

/tmp/testfile :
-----
test1 nameofvalue1 {22.22}
-----

item key :
-----
vfs.file.regexp[/tmp/testfile,"test1 .*\{([0-9]+|[0-9]+\.[0-9]*)\}",,,,\1]
-----

I got value 22.22 by add item for host.

Please try add that item.
not use zabbix_agentd -t command.

Funny :

root@zabbix2-4-FE:~# zabbix_get -s 172.31.1.118 -k vfs.file.regexp[/tmp/testfile,"test1 .*\{([0-9]+|[0-9]+\.[0-9]*)\}",,,,\1]
1

root@zabbix2-4-FE:~# zabbix_agentd -t vfs.file.regexp[/tmp/testfile,"test1 .*\{([0-9]+|[0-9]+\.[0-9]*)\}",,,,\1]
vfs.file.regexp[/tmp/testfile,test1 .*\{([0-9]+|[0-9]+\.[0-9]*)\},,,,1] [s|1]

BUT
test file
vfs.file.regexp[/tmp/testfile,"test1 .*\{([0-9]+|[0-9]+\.[0-9]*)\}",,,,\1]
30 365 - Zabbix agent 2015-05-12 09:48:41 22.22

If it's not a bug, (it's a feature ?) I don't understand.

Thank you. I try with my items and I go back.

I think that double quotes are interpreted by shell.
Please try execute this command line.

zabbix_agentd -t "vfs.file.regexp[/tmp/testfile,\"test1 .*\{([0-9]+|[0-9]+\.[0-9]*)\}\",,,,\1]"
