Unable to see PowerBI Activator Alerts

chnunez — Tue, 01 Sep 2026 16:51:54 GMT

I think I created an alert as a test and now I'm getting daily alerts in Teams from Activator. I tried to turn the rule off, but the link takes me to a Power BI app space I don't use, and I just see an error message.

I tried to stop the Teams messages by deactivating the bot and now I get daily emails from Activator. I don't see any rules on the report that I made the test alert on either.

How do I turn this off? One day I might actually want to use Activator alerts but I can't even manage them right now....and I work at Microsoft

Text not shown in activator Alert msg

ram142more — Wed, 19 Aug 2026 05:24:49 GMT

Hi Team,

I am trying to show failed pipeline in activator with failed pipeline name but it wont show any variable after entering @ for Pipeline.

Can anyone guide me how to show text in activator alert msg, please?

Activator + Fabric deployment: Not possible to parametrize triggered pipelines.

Tsubasanut — Thu, 23 Jul 2026 11:21:39 GMT

Disclaimer: I used ChatGPT to help me compile the message, but the problem itself was found and tested by me.

I’m seeing inconsistent behavior when deploying Activator items across Fabric deployment pipeline stages.

Scenario

We have a standard three-stage setup:

DEV workspace
TEST workspace
PROD workspace

Each workspace contains:

a Lakehouse used as the event source
an Activator item
a Fabric Pipeline used as the action target

The intended flow is:

A folder/file is created in the Lakehouse.
Activator receives the OneLake/Lakehouse event.
Activator triggers the Pipeline in the same workspace/stage.

So the expected behavior is:

DEV Lakehouse event → DEV Activator → DEV Pipeline
TEST Lakehouse event → TEST Activator → TEST Pipeline
PROD Lakehouse event → PROD Activator → PROD Pipeline

UI confusion

Firstly, the Activator UI can show the action target workspace as if it is correct. However, runtime behavior shows that the underlying workspace/item references are not consistently remapped.

I also found a difference depending on how the rule is authored:

If I create the activation rule from the Pipeline side, Fabric creates an event/action configuration that appears to remap correctly during deployment. So the Activator in DEV workspace points to pipeline in DEV workspace, and rhe Activator in TEST workspace points to same pipeline in TEST workspace
If I create an equivalent rule directly from the Activator UI, the workspace text in Action-Fabric item is not changing after deployment. So the Activator in DEV workspace points to pipeline in DEV workspace, and rhe Activator in TEST workspace also points to pipeline in DEV workspace. However, when event happens, the pipelines are executed in different workspaces.

So two visually similar Activator rules appear differently in the UI, while behaving the same way.

Activator content

At first, I created one event. But then I found out, that event source cannot be remapped during deployment. So DEV Lakehouse will always be a source for the event in all 3 workspaces.
Therefore, to test how Activator behaves across stages, I created one event for each physical Lakehouse: DEV, TEST, and PROD. The expectation was not that the event source itself would be remapped, but that the action target would remain correctly associated with the corresponding Pipeline for that event/stage.

Observed behavior

I created a test Activator containing three events/rules: one for the DEV Lakehouse, one for the TEST Lakehouse, and one for the PROD Lakehouse. Each event/action was intended to trigger the corresponding Pipeline in the same workspace.

After deploying the Activator, Pipeline, and Lakehouse through the deployment pipeline, the runtime behavior was inconsistent:

Creating a folder in the DEV Lakehouse triggered three pipeline runs, one in each workspace.
Creating a folder in the TEST Lakehouse triggered three pipeline runs, two in TEST and one in PROD.
Creating a folder in the PROD Lakehouse triggered three pipeline runs, all in PROD.

This creates a serious CI/CD risk.

If an Activator definition contains event sources from multiple stages, those source subscriptions appear to remain fixed after deployment. Then, depending on how action targets are autobound, a single Lakehouse event can trigger multiple deployed Activators and run Pipelines in unexpected workspaces.

For example:

a DEV Lakehouse event can trigger TEST or PROD processing
a TEST event can trigger PROD processing
multiple deployed Activators can react to the same physical OneLake event

This is not safe for deployment pipelines.

Rule conditions and parameters cannot solve the issue at the moment

I tried to use Activator rule conditions/action parameters to guard against this. However, all available fields appear to come only from the source event payload:

source
subject
time
id
type
data.url
data.blobUrl
data.requestId
data.clientRequestId

I do not see any way to reference:

current Activator workspace
current Activator item ID
current deployment stage
target action workspace
target Pipeline workspace
Fabric Variable Library values

Because all deployed Activators that subscribe to the same physical OneLake event see the same event payload, rule conditions cannot distinguish “this Activator belongs to this workspace” unless some environment-specific value is manually patched after deployment. Same for the triggered artifacts - they have no idea which Activator (DEV, TEST or PROD) was used for triggering.

Suggested fix from Microsoft

Making Activator event/action references deployment-safe. Either by adding deployment rules to Activator class, exposing more runtime context to the Activator, or making triggered artifacts aware about Activator itself.

Also, the Activator UI should not show an apparently correct target workspace if the runtime binding is different.

Current workaround

The only safe workaround I can see is to avoid deploying similar Activators altogether, or patch Activator references after deployment.

I would glad if someone could offer another solution to this problem of mine.

Activator: issue when set an action by posting a message in Teams channel

XCT — Thu, 18 Jun 2026 09:51:17 GMT

Hi,

I've succeeded in triggering an alert based on a KPI in a Power BI report, and that works fine.

However, I want to send a message to my community in a Teams channel. When I select the appropriate option in the Activator action pane, I can't select the team or the channel, even though I'm signed in with my account.

It's strange because email and personal Teams messages work without any issue.

Thx for your support!

Activator Email Delivery Inconsistent — Alerts Recorded in History but Emails Delayed and Missing

Akshay3071 — Sun, 17 May 2026 19:21:02 GMT

Hi,

I am currently working with Microsoft Fabric Activator, where I have configured an alert on a KQL function output from an Eventhouse datasource. The alert is designed to trigger every 10 minutes, based on a change detection condition on a computed column (AlertTriggerKey) that increments on every 10-minute window.

Observed Behavior

Activator is detecting the condition and recording each trigger correctly in the alert history, confirming that the rule evaluation and condition matching are functioning as expected. However, the email delivery cadence is inconsistent and does not align with the expected 10-minute interval.

Specifically, the pattern I am observing is inconsistent and does not follow a fixed delay. While some alerts are delivered on time, others arrive with unpredictable delays ranging from 30 minutes to over an hour, and certain alerts are missed entirely with no corresponding email delivery whatsoever. There is no consistent gap between the expected trigger time and the actual email delivery time — the delay varies arbitrarily across alerts and some triggers recorded in Activator history have no corresponding email delivered at all, making it impossible to rely on the notifications for real-time operational decisions.

What Has Been Verified

Rule configuration is correct
Trigger condition (AlertTriggerKey → Changes) is working as expected
Activator history confirms alerts are being recorded at the correct 10-minute intervals
Throttle limit is not being hit — only 6 alerts per hour
Recipients and action configuration are correctly set up
Emails are not being filtered into spam or junk

Core Issue

The alert history and the email delivery are out of sync. Activator is recording the trigger at the correct cadence, but the email notifications are being delivered with delays and in some cases are dropped entirely, suggesting the issue lies specifically in the email dispatch pipeline, not in the rule evaluation or condition detection layer.

Has anyone encountered a similar pattern where Activator history is accurate but email delivery is inconsistently delayed or completely missing? Is there a known latency issue or queuing behavior in the Fabric Activator email dispatch system that could explain this? Any guidance or workaround would be greatly appreciated.

Thank you.

[Fabric Activator] System Notification

NikNithiy — Mon, 04 May 2026 10:44:44 GMT

Can any one tell me what is this error. My manager says that we get this same mail atleast 100 per day. He have no idea why he get this.

Lakehouse File name

wanwar — Fri, 01 May 2026 16:16:16 GMT

Using an activator to trigger a pipeline based on a new file created in the Lakehouse, the pipeline accepts a paramter for filename, in the pipeline i have added the folder in the File path and for the file name i want to use the parameter value thats coming from the activator but I can't seem the find a Tag to get just the file name to pass, i have tried __source and @__subject both are giving me full folder path so the pipeline fails with "Not found"

any ideas.

Thanks

User Data Function: 'NotFound' Error (WorkloadException) after Publishing, but Success in Develop

Izyaan_sc — Mon, 23 Mar 2026 12:54:47 GMT

I am setting up a monitoring workflow in Microsoft Fabric using Fabric Activator. I have created an alert based on a KQL query that monitors row ingestion. kql query -

table1

| where ingestion_time() > ago(10m)

| summarize RowsIngested = count()
I am calling a User Data Function (UDF) as the action to push this data to an external Mimir endpoint via Remote Write.

@udf.function() def testFunction(metricName: str, metricValue: float, labels: dict) -> str: logging.info(f"Starting Prometheus Remote Write push for: {metricName}") try: writer = RemoteWriter( url=MIMIR_URL, auth={ "username": MIMIR_USERNAME, "password": MIMIR_PASSWORD } ) if not isinstance(labels, dict): logging.error("Input 'labels' was not provided as a dictionary/object.") return "Push failed: labels must be a JSON object" timestamp_ms = int(datetime.datetime.now().timestamp() * 1000) metric_definition = labels.copy() metric_definition["__name__"] = metricName series = [ { "metric": metric_definition, "values": [float(metricValue)], "timestamps": [timestamp_ms] } ] writer.send(series) logging.info(f"Successfully pushed {metricName} to Mimir.") return f"Metric pushed successfully at {datetime.datetime.now()}" except Exception as e: logging.error(f"Remote Write failed: {str(e)}") return f"Push failed: {str(e)}"

1. Develop Mode (Success)

When testing the function in Develop Mode using the Test Panel with the following parameters:

metricName: "fabric_rows_ingested_test"
metricValue: 111
metricLabels: {"workspace": "dev", "table": "table1"}

Output: "Metric pushed successfully at 2026-03-23 06:53:51" Logs: Successfully pushed fabric_rows_ingested_test to Mimir.

above exposed metric can be accessed in grafana.

2. Run/Published Mode (Failure)

After clicking Publish and ensuring all libraries (prometheus-remote-writer, requests) are listed as "Published" in Library Management, I switch to Run only mode & invoke the function,

{ "functionName": "testFunction", "invocationId": "00000000-0000-0000-0000-000000000000", "status": "Failed", "errors": [ { "errorCode": "WorkloadException", "subErrorCode": "NotFound", "message": "User data function: 'testFunction' invocation failed." } ] }

Why does the Fabric backend fail to resolve the endpoint in Published mode (returning NotFound) when the same function is fully functional in the Develop sandbox?

Event trigger based on power bi report every 12 hours

IMett — Tue, 17 Mar 2026 09:13:46 GMT

Hi everyone,

I am still very new to Activator and try to build our first business alerts based on a Power BI Report.

I have set up a rule in this was:

My expectation was to get an alert every 12 hours if the condition is met. However, in reality, I get an alert every hour.
Which brings me to the following questions:

- According to the live feed, a data point is created once an hour. Where does this interval come from? I can't figure out where I might have configured that. Ideally, I would like to change this interval to "every 12 hourse" and then just trigger whenever the condition is met.

- If for some reason this is not possible, what is the best way to only trigger an event every 12 hours?

Activator Teams Alert

JCSchuman — Wed, 11 Mar 2026 17:07:59 GMT

I've set alerts on multiple PBI service reports and none of them are firing. I've tried changing the conditions for the trigges but nothing seems to work. The alerts save, and are set, and the test alert goes through fine each time, but that's it. The alert is for whenever the value in a column contains "CRT3".

Not able to creat alert over a table chart without removing columns

dcadena — Wed, 11 Mar 2026 16:30:25 GMT

I've been creating alerts on a table chart based on different filtering, however it stopped allowing me to create alerts on that table since 3 days ago, as a test I removed all the alerts previously created and now I cannot create any new alert over that table chart.

I tested by removing columns and that is the only way i'm able to create alerts again on that table chart card, then republishing the report adding the deleted columns.

With all the columns I'm able to select the column to base the alert but after that, the alert it is not created, and I'm not able to proceed:

Creating ICMs via Activator

iremugurlu — Wed, 11 Mar 2026 09:58:51 GMT

I'm trying to create ICMs through Activator. But my test action is failing. I guess I need to give some permissions or use a specific connector. Or maybe my connector is wrong type? Would be great if I can get some help on what I'm doing wrong.

Fabric known issue ID 1719

nxadmin — Thu, 05 Mar 2026 07:24:31 GMT

Hello,

I am referring to Fabric known issue ID 1719: we have implementend activator alerts sending emails with context properties as parameters; we are using and do require the 'when it has been true for' condition in these alert rules. We want to move our solution to production, but unfortunately this is not possible with faulty emails where parameters are not rendering. Does anyone know when a fix for this issue can be expected?

Tnx in advance and best, flo.

Enable configurable recipients for Activator error notifications - critical for monitoring

pwand — Sun, 08 Feb 2026 23:51:43 GMT

According to the official documentation: "If a problem occurs with any of your Fabric Activator events, objects, or rules after you create them, then Fabric Activator sends you an email containing an error code."
However:

The recipient is not configurable (hardcoded to item creator only)
This limitation is not documented
No alternative notification channels are available

This creates a critical blind spot for production monitoring when:

Activators are deployed via service principal (cannot receive emails)
The original creator leaves the team or changes roles
Multiple team members need visibility into system errors

Requested Feature:
Enable configuration of error notification recipients through:

Workspace-level notification settings
Distribution list/group email support
Integration with workspace contacts/admins

Use Case:
Our production Activators are deployed via CI/CD pipelines using service principals. Without configurable notifications, we have no way to receive critical error alerts, making Activator unsuitable for production use

Propoperties Issue - "Value" instead of list of columns

MorenaBI — Wed, 21 Jan 2026 07:49:15 GMT

Hi,

I'm trying to set up an alert on my power bi report based on a table. I generate the alert by clicking on the table. When I try to edit the activator object and add addtional properties, instead of list of columns I see "value". Any ideas?

When I try to create a new object based on the power bi report stream, I also see the same, so a new object can't be created.

How to include multiple columns in Activator

rabbisht — Thu, 08 Jan 2026 13:56:45 GMT

Previously, the activator message supported composite keys, allowing multiple column values to be included. The current implementation targets only a single column. Is there still a way to include values from multiple columns in the activator message?

Monitor all the pipeline failures and send a Teams alert

JoanAmal — Mon, 08 Dec 2025 16:09:15 GMT

Trigger activator action only if condition is met over certain time period

Mauro89 — Fri, 28 Nov 2025 07:37:54 GMT

Hi there,

Iam searching for a possibility to only trigger a action with the activator if the condition is met once and then only lets say after an hour and if the condition is met again.

Example: I want to get a Teams message if my capacity exeeds 95% of interactive delay limit. And I dont want to get this message every time this condition is met, but only for example if the condition holds and then checking again after x amount of time.

Any ideas?

Thanks and best regards!
