Deployment Server issue after upgrading 9.1 to 9.4.5

verbal_666 — Wed, 05 Nov 2025 09:20:29 GMT

Hello.

I'm having new issues after upgrading a DS from V.9.1 to V.9.4.5.
Every phone-home from the UFs (i have about 2000 UFs), gives a 0 [ZERO] in UI.
I can see UFs connected to 8089 of my DS Listener, many errors on Splunk logs,

AdminHandler:AuthenticationHandler [289178 TcpChannelThread] - Denied session token for user: splunk-system-user

On UFs i have the classic "deploymentclient.conf", with a simple,

[target-broker:deploymentServer] targetUri = myDS:8089

With previous versions i never had issues.

Has something changed in 9.4 for UFs to DS connect?

Thanks.

If it's after upgrading to 9.2+, add below configuration under outputs.conf in the deployment server, then restart splunk.

[indexAndForward] index = true selectiveIndexing = true

Ahhhhhhhhhhhhhhhhhhh!!! 😚

So the DS must index locally and then send data to Indexers... 👍👍👍

Thanks 👏👏

If for any reason you arent able to index locally using selectiveIndexing (e.g. small local disk) but can forward to your indexers then I have found that setting the Deployment Server up to be able to search against the search peers also fixes the UI and allows management of the agents without local indexing.
