Problems with director

hi, good morning.

I have a problem with some things in director, example, when add a host there is not problem, but when i go to agent tab in the host, i have this message:
#0 /usr/share/icingaweb2/modules/director/library/Director/IcingaConfig/AgentWizard.php(109): Icinga\Module\Director\IcingaConfig\AgentWizard->getTicketSalt()

What Icingaweb module(s) do you have installed and what version are they?

99% of the time that I see a PHP error with director, it’s either that I didn’t install one of the supported modules (IPL, Incubator, and reactbundle), or I have a missing PHP library (listed under the same link above).

i can fix this error updating director, but now i have this messsage in agent tab:

Please check the Icinga 2 Client documentation for more related information. The Director-assisted setup corresponds to configuring a Top Down environment.

A ticket for this agent could not have been requested from your deployment endpoint: Ticket salt is not configured in ApiListener object

I dont known what to do

Well, did you check the Icinga 2 Client documentation?
Is there any more information you can give for your problem?

If you haven’t figured it out yourself already, you can try the following.

Add this ticket_salt = TicketSalt attribute to the ApiListener object in /etc/icinga2/features-enabled/api.conf and make sure that the TicketSalt constant is being set in /etc/icinga2/constants.conf.

Thanks! works!
You known why happend this? agent tab works, but i upgrade the system and then start the problem

Unfortunately I can’t tell you anything as I don’t know for sure how it was before. Maybe you or someone else accidentally or intentionally removed this attribute from the ApiListener object configuration!.

I don`t kwown, this started after a yum upgrade.


Possible that you yum upgraded a PHP package to the wrong version?
