**Solución**: Activar el uso de comandos para que los Frameworks web puedan utilizarlos, la no activación de esta propiedad suele ser la causa más común. Antes de ello se debe comprobar que la ruta y permisos están correctamente configurados (puede ser la otra causa del problema).

<code bash>
cat /etc/icingaweb2/modules/monitoring/instances.ini

[icinga]
transport           = "local"
path                = "/var/run/icinga2/cmd/icinga2.cmd"

ls -ltd /var/run/icinga2/cmd/
drwx--s--- 2 nagios www-data 60 abr 11 20:14 /var/run/icinga2/cmd/</code>


<code bash>icinga2 feature enable command
service icinga2 restart</code>
