i totally agree.  This app does not handle 400 or 404 errors.  The developer  @jconger   is top notch though, i have met him.  just this one app have never really worked correctly We have to reset the inputs almost daily  By reset, we create a new subscription input.  Or we have to disable/reenable the call record or user report inputs However, i did perform the kvstore clean on both of our heavy fowarders (behind Load balancer) for a load balancer environment webhook, call record, and user report inputs are setup on both HF, but subscription is setup on only one This worked for me, for now disable all inputs  clean kvstore splunk clean kvstore -app TA_MS_Teams -collection TA_MS_Teams_checkpointer enable inputs in this order webhook, subscription, call record, user report   we have data again...for now.              ...

The incidents and alerts inputs for this add-on work perfectly!  We bring them in all day.   The alert_actions do not work very well.  We are using the workaround @jconger  mentioned below.   We have the makeresults command setup as a scheduled report to bring in custom advanced threat hunting queries.  @jconger  - on the next release, could you add a custom KQL input?  This would be similar to how TA for Defender ATP hunting API | Splunkbase does this.  There is an input to simply run the KQL against defender api.  The makeresults command already has the correct structure.  ...

I have not seen a reliable way to pull in Log Analytics workspace data into splunk https://splunkbase.splunk.com/app/4127/ - no longer functions on 8.2.x - developer no longer updating the add-on.  This was a great add-on, worked for 2 years.   now it's gone   https://splunkbase.splunk.com/app/4847/ - This will pull in the data, but it's a mess.  There are no field extractions, and it pulls in data you do not need like table structure, and row structure.  But it does not map them together or extract a single field.  There is an option for CSV or JSON, both do the same thing, just brings in a pile of data.  Splunk has nothing for this.   ...

nice response.  Thank you. What if the event log has spaces, found in the Applications and services node?

maybe, if you have time from all the .conf questions you have coming in; make an input that only runs the hunting queries? the only last thing we have is the timestamp recognition.  it uses the calling time instead of the Timestamp you have configured.  ... View more

hi jason, one question about the timestamp parsing using your makeresults command.  All the events come in with the exact same _time value.   so we get this when searching Events might not be returned in sub-second order due to search memory limits. See search.log for more information. Increase the value of the following limits.conf setting:[search]:max_rawsize_perchunk." Where do you set the timestamp parsing?  we tried props, but it did not take affect   ... View more

Affirmative.  Installed on both Heavy Forwarder and search head cluster.  We have continued to run into issues with the alert_action The Event Hub works well from Defender, the challenge is volume.  Our defender data brings in 1.5TB per day into Splunk.  The SOC needs the Advanced Threat hunting data along with the incidents and alerts.   We were using Add-on for Defender ATP Hunting API to bring in the Hunting API.  However, that stopped working with 8.2.   So we are considering a method to use the Event Hub, and then maybe filter inputs to only what we need.  A poor man's threat hunting?  ...

Any information, documents, writeups or examples on how to use these new Alert actions would be incredibly useful.  What is the variable format in the Incident Update alert action?  I'm assuming $fieldname$?  for the Hunting query, do we need to replace the > character with ;gt ?   We have the inputs on a heavy forwarder and the add-on installed on the search head cluster.   ...
