Hi, I am new to Icinga, so bear with me 🙂 I am deploying a new system but have some issues getting the Director Deamon running. I have run through the prerequisites a million times, however I cant resolve this PHP error that pops up (similar issue with the vSphere Plugin) When I try to start the deamon (icingacli director deamon rum) I get this: PHP Fatal error: Uncaught Error: Call to undefined function posix\_getpid() in /usr/share/icingaweb2/modules/director/library/Director/Daemon/DaemonProcessDetails.php:97 Stack trace: #0 /usr/share/icingaweb2/modules/director/library/Director/Daemon/DaemonProcessDetails.php(28): Icinga\Module\Director\Daemon\DaemonProcessDetails-\>initialize() #1 /usr/share/icingaweb2/modules/director/library/Director/Daemon/BackgroundDaemon.php(109): Icinga\Module\Director\Daemon\DaemonProcessDetails-\>\_\_construct(‘d9a5480f0d78401…’) #2 /usr/share/icingaweb2/modules/director/library/Director/Daemon/BackgroundDaemon.php(78): Icinga\Module\Director\Daemon\BackgroundDaemon-\>initializeProcessDetails(false) #3 /usr/share/icingaweb2/modules/director/library/Director/Daemon/BackgroundDaemon.php(52): Icinga\Module\Director\Daemon\BackgroundDaemon-\>initialize() #4 /usr/share/icingaweb2/modules/reactbundle/vendor/react/event-loop/src/Tick/FutureTickQueue.php(46): Icinga\Module\Director\Daemon\BackgroundDaemon-\>Icinga\Module\Director\Daemon{closure}() # in /usr/share/icingaweb2/modules/director/library/Director/Daemon/DaemonProcessDetails.php on line 97 Fatal error: Uncaught Error: Call to undefined function posix\_getpid() in /usr/share/icingaweb2/modules/director/library/Director/Daemon/DaemonProcessDetails.php:97 Stack trace: #0 /usr/share/icingaweb2/modules/director/library/Director/Daemon/DaemonProcessDetails.php(28): Icinga\Module\Director\Daemon\DaemonProcessDetails-\>initialize() #1 /usr/share/icingaweb2/modules/director/library/Director/Daemon/BackgroundDaemon.php(109): Icinga\Module\Director\Daemon\DaemonProcessDetails-\>\_\_construct(‘d9a5480f0d78401…’) #2 /usr/share/icingaweb2/modules/director/library/Director/Daemon/BackgroundDaemon.php(78): Icinga\Module\Director\Daemon\BackgroundDaemon-\>initializeProcessDetails(false) #3 /usr/share/icingaweb2/modules/director/library/Director/Daemon/BackgroundDaemon.php(52): Icinga\Module\Director\Daemon\BackgroundDaemon-\>initialize() #4 /usr/share/icingaweb2/modules/reactbundle/vendor/react/event-loop/src/Tick/FutureTickQueue.php(46): Icinga\Module\Director\Daemon\BackgroundDaemon-\>Icinga\Module\Director\Daemon{closure}() # in /usr/share/icingaweb2/modules/director/library/Director/Daemon/DaemonProcessDetails.php on line 97 This is the installed php modules: [PHP Modules] bcmath bz2 calendar Core ctype curl date dom exif fileinfo filter ftp gd gettext hash iconv intl json ldap libxml mbstring mysqli mysqlnd openssl pcntl pcre PDO pdo\_mysql pdo\_sqlite Phar posix readline Reflection session shmop SimpleXML sockets sodium SPL sqlite3 standard sysvmsg sysvsem sysvshm tokenizer xml xmlreader xmlwriter xsl zip zlib As I said, I am a newbie(also on Linux) but do any of you know what this is caused by? ---

Hi and welcome 🙂 did you restart the webserver and, depending on the distribution your are running, the php-fpm service after installing the modules? For Debian/Ubuntu that should be `systemctl restart apache2` For RHEL8/CentOS8 `systemctl restart httpd` and `systemctl restart php-fpm` In future please provide some more detailed information about the system you are running and versions of icinga/icingaweb/director/modules is use 🙂 Cheers log1c ---

Hello, please have a look on your `icingacli` which PHP version is used by it: ```auto cat /usr/bin/icingacli ``` On the first line you will see which PHP version is used. Afterwards ensure you installed all required packages for this PHP version. For example, if you are using CentOS and `rh-php73` you will have to ensure that the packages ```auto rh-php73-php-posix rh-php73-php-soap rh-php73-php-cli rh-php73-php-process ``` are installed. Once done, restart the Icinga Director service and try again. It looks like you are simply missing the required PHP package for your used PHP version. ---

Thats embarrassing 🙂 It was a mixup of PHP versions @cstein this solved the issue! Thanks for helping out!
