Telegraf: Problem with plugin exec (format error for command)

[marinonjalsson]

The error !!

sudo -u telegraf /opt/telegraf/telegraf -config /etc/opt/telegraf/telegraf.d/test.conf -test
2015/12/07 09:42:44 exec: fork/exec /opt/snara/slog/slog-netstat-test2.sh: exec format error for command '/opt/snara/slog/slog-netstat-test2.sh'

But the json seems to be ok

sudo -u telegraf /opt/snara/slog/slog-netstat-test2.sh 
{ "sf_queue": 0 }

FROM: /etc/opt/telegraf/telegraf.d/test.conf

[exec]
[[exec.commands]]
command = "/opt/snara/slog/slog-netstat-test2.sh"
name = "netstatX"
interval = 10

Version:

/opt/telegraf/telegraf -version
Telegraf - Version 0.2.3

Any thoughts?

certainly looks like a bug, I'll look into it, thanks for the detailed report @marinonjalsson

@marinonjalsson I haven't been able to reproduce, here is my script:

$ cat /tmp/422.sh
#! /bin/bash
printf '{ "sf_queue": 0 }\n'
$ ls -l /tmp/422.sh
-rwxr-xr-x 1 csparr wheel 43 Dec  7 11:08 /tmp/422.sh*
$ whoami
csparr

And collection works fine for me:

$ ./telegraf -config ~/ws/telegraf.conf -filter exec -test
* Plugin: exec, Collection 1
> exec__sf_queue value=0 1449511964082654340

What OS are you running on? Can you send me output of the commands that I executed above?

@marinonjalsson This might be a 32/64 bit architecture issue? I found this case: http://askubuntu.com/questions/447709/im-getting-exec-format-error-when-i-try-to-run-an-executable

please run uname -a and uname -m on your system and show the output

[marinonjalsson]

Thank you for your reply.
OS:

$ uname -a
Linux thor 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1+deb8u6 (2015-11-09) x86_64 GNU/Linux
$ uname -m
x86_64

I'm running the telegraf_0.2.3_amd64.deb package.
all 64:

I will test your script next.

@marinonjalsson Can you include the full text of your test script? And show the file permissions on it? (ls -l /opt/snara/slog/slog-netstat-test2.sh)

[marinonjalsson]

SOLVED.
I forgot the shebang in all my test-scripts.
Added

#! /bin/bash

... and its working. @sparrc thanks for the help

[sparrc]

great!
