Hi,

my Icinga-Web is running for months, but now I'am unable to send commands.

So I tried to get every Info. Here is what I found.

>>>> EMPTY <<<<

I created a text file at /tmp/icinga2.cmd to see if any command reaches it. But it stays empty.

Can you give me a hint to fix this?
The file is writeable for everyone.
I can't find any error.

After a clear cache Icinga-web writes to file.

But at the pipe I can see the following:

[2015-12-01 15:00:13 +0100] information/ExternalCommandListener: Executing external command: [1448978413] PROCESS_SERVICE_CHECK_RESULT;k82.xxxx.local;SAP_SMQ2_CHECK;0;SMQ2 OK 9 Entries.: |QUEUES=6 ENTRIES=9 SYSFAIL=3 READY=3 RUNNING=3;0;0

Looks like a missing \n or something?

I think this could be a Bug at Icinga2 because this was the last component I updated.

IcingaWeb2 is working, but if I send Commands vom IcinigaWeb1x they don't appear in Icinga2 Log as external Command.

I have the same issue but i think i have found a solution:

I think the reason of this behavour is that icinga 2 expects that there is an \n at the end of the command, but icinga-web uses printf to send the command which does not add a new-line character.

The corresponding icinga 2 commit: github

The corresponding code line in the icinga-web repo: github
