Hi Ian
Good idea! If I am not mistaken, Icinga2 uses an user "nagios" to run the service. Indeed I do receive the same output! root@server1100:/tmp# sudo -u nagios /usr/lib/nagios/plugins/countdown_to_date.php --date 2013-02-11 --warning 60 --critical 30 Could not open input file: /usr/lib/nagios/plugins/countdown_to_date.php This is the only php plugin that I am using, therefore the user nagios might not be able to run php. But it seems that the "others" do have execution permission: (/etc/alternatives/php points to php7.2) root@server1100:/tmp# ls -la /usr/bin/ | grep php lrwxrwxrwx 1 root root 21 Jun 1 14:07 php -> /etc/alternatives/php -rwxr-xr-x 1 root root 4500312 May 2 10:23 php5.6 -rwxr-xr-x 1 root root 4895768 Jun 22 08:45 php7.2 Running the command using sudo does work: nic@server1100:/tmp$ sudo /usr/lib/nagios/plugins/countdown_to_date.php --date 2013-02-11 --warning 60 --critical 30 [sudo] password for nic: CRITICAL: 1990 days have past since 2013-02-11 I found the culprit thanks to this stackoverflow post [0] "Scripts must have read permission so that their interpreter can read them.". Therefore the following worked: chmod o=r+x /usr/lib/nagios/plugins/countdown_to_date.php Though I might to consider only giving the nagios user access to that file and not every other user on the system. Maybe a sudoers edit can help out. Thanks for your input, helped me to look at it from another angle!

The thing is that local execution works: root@server1100:/tmp# /usr/lib/nagios/plugins/countdown_to_date.php --date 2013-02-11 --warning 60 --critical 30 CRITICAL: 1990 days have past since 2013-02-11 And that Permissions are properly (according to the other plugins): root@server1100:/tmp# ls -la /usr/lib/nagios/plugins/ | grep count -rwxrwx--x 1 root root 48139 Jul 25 12:44 countdown_to_date.php But I get the following error message in the GUI: [cid:image001.png@01D42427.E85A8D40] I tried to remove the "-q" option from line 1 from the script, like was suggested on stackoverflow [1] but that didn't work. Here's the command definition also: object CheckCommand "Countdown" { import "plugin-check-command" command = [ PluginDir + "/countdown_to_date.php", "--date", "2013-02-11", "--warning", "60", "--critical", "30" ] } Has anyone an idea what I'm missing? Cheers, Nic PS: I know that the date I'm passing doesn't make a lot of sense, but its a POC at the moment ;-) [0] https://exchange.nagios.org/directory/Plugins/Others/countdown_to_date/details [1] https://stackoverflow.com/questions/4567688/problems-with-a-php-shell-script-could-not-open-input-file [https://cdn.sstatic.net/Sites/stackoverflow/img/apple-touch-i...@2.png?v=73d79a89bded]<https://stackoverflow.com/questions/4567688/problems-with-a-php-shell-script-could-not-open-input-file> bash - Problems with a PHP shell script: "Could not open input file" - Stack Overflow<https://stackoverflow.com/questions/4567688/problems-with-a-php-shell-script-could-not-open-input-file> stackoverflow.com Ok, I am trying to create an email logger, that uses a PHP shell script.
