Information event storm

Solved335 views27th June 2025authentication failure information events

Arunkrishna Shreeder [SLC] [DevOps Enabler]4.13K 19th March 2025 0 Comments

Hello,

For the past few days, we have been seeing an information event storm from one event on our standalone DMA :

We can see this in SLNet log file too, continuously :
2025-03-19 09:26:25.446|210|AuthenticationStep|
2025-03-19 09:26:25.462|210|AuthenticationStep|
2025-03-19 09:26:25.462|210|AuthenticationStep|
2025-03-19 09:26:25.462|210|AuthenticationStep|
2025-03-19 09:26:25.462|210|Authentication|Had a failed authentication request from \TMD (TMD MAM (<not authenticated> @ TMD))
2025-03-19 09:26:25.478|210|Destroy|Connection did not authenticate. Computer: TMD Application: TMD MAM Max Connection Attempts: 40
2025-03-19 09:26:25.524|36|Facade.HandleMessage|Incoming (Local SLNet): Alarm: 15265125 (Connection did not authenticate. Computer: TMD Application: TMD MAM Max Connection Attempts: 40 ) - 106305/*****-DM-STA/Authentication Failure at 03/19/2025 09:26:25 [cleared]

We previously had this element using the driver TMD MediaFlex UMS which integrates the Mediaflex Unified Media Services Cloud platform into DataMiner.
This platform pushes the list of scheduled events to the DataMiner connector, which in turn will display the events in a table and trigger an Automation script, automatically or manually, to create the corresponding SRM bookings.

But now, the element, connector has been deleted from this DMA several days back and there is nothing in automation, correlation modules that is generating these events.
Is there a way to ensure we no longer get these information events ?
Thank you.

Hi Arunkrishna,

At first sight, it looks like the TMD application might be trying to initiate a connection to the DataMiner System. Possibly there is some configuration on the TMD app that also needs to be disabled?

Hi Michiel, this would most likely have been the case; the user probably did not clean up after removing the device. Thanks for your feedback!
