i installed a new splunk enterprise server and configured it as deploy server as documented here:
https://docs.splunk.com/Documentation/Splunk/8.2.5/Updating/Aboutdeploymentserver
then i added an app in $SPLUNK_HOME/etc/deployment-apps/MyApp
on the 26 forwarders running ubuntu 20.04 i ran splunk set deploy-poll MyDS:8089 but only 20 of them show up in the forwarder management.
when i remove one of them by clicking on "delete record", i can add a missing one by running splunk set deploy-poll MyDS:8089 again.
a license is installed too and it says 'DeployServer': 'ENABLED'
any ideas?
thanks...
found the stupid mistake
the not showing forwarders where restarted and splunkd wasn't configured to start on boot 😞
unfortunately 'splunk set deploy-poll MyDS:8089' does not complain about not running splunkd.
anyway, changed config and all forwarders show up...
next issue probably coming soon 😉
Check if there is no connection issues from the missing UFs
You can use open ssl in CLI to test this from each UF host.
openssl s_client -connect MyDS:8089
If everything is fine you should see the details on the cert of your DS. If not, you might have something blocking the connection
that's not the problem.
connection works from all clients...
