check_nrpe changes ouput data after | token

[Dietervdb]

Hi All,

I have a Powershell script on a client that is being triggerd by check_nrpe (version 3.2.1) from our Nagios server.
To do this we us on the client nsclient++ (version 0.5.2035).
Because I want to use performance data, I use the | token in the output of the Powershell script.

The code is for example:

echo "test | test"
exit 0

This produces the expected output:

PS C:\Program Files\NSClient++\scripts> .\test.ps1
test | test

But check_nrpe transforms everything ater the | token:

/usr/local/nagios/libexec/check_nrpe -H testhost-t 60 -c check_test
test |'test'=0

By this, I am unable to work with performance data in Nagios.
I already set 'allow nasty characters' to 'true', but no difference.

Do you guys have any idea what causes this problem?

Thanks,
Dieter

Performance data needs to have a specific format
