Alert for failed tasks - with log4net appender

dana — Wed, 29 Jan 2025 15:57:23 GMT

Hi People,

I'm trying to implement "SMTP email notification Qlik Sense on task failure" based on the sources published by Christof Schwarz

https://www.youtube.com/watch?v=Px4pvSlqK0s

https://github.com/ChristofSchwarz/qs_log4net_appender

My server version is May 2022.

but, unfortunately, it didn't work.

I did a couple of modifications based on other posts, but, still, with nosuccess.

Regarding smtp.gmail.com:

I defined the port based on my account definition (465). Is that correct?

Is the user name the full mail address?

bellow is the XML I'm using.

Would appreciate some help!

Thanks!

Using the Log4Net SMTP appender will give you basic emails for ALL failed reload tasks.

This is a good start, but if you want better/more informative alert emails you need some other solution.
Or if you want alert emails for just some reload tasks, or different recipients for different tasks.

I'm the creator of the Butler open source (free!) tool that offers a pretty comprehensive set of features around failed reload alerting, more info here: https://community.qlik.com/t5/Qlik-Sense-Documents/Sending-e-mail-alerts-in-Qlik-Sense-Enterprise-Task-Failures/tac-p/2066335/highlight/true#M5713

Hi,

Thanks for this helpful link..

I've used the example configuration posted there, but it still doesn't work.

As some people commented there, it might not work with later versions of Sense.

I share their frustration, and hope someone from support, will check and to resolve it.

Thank you!

Hi,

Currently, I need a simple and quick solution, and I'm pretty upset with not being able to get it working..

Does Butler require changing settings of Sense environment?

Thanks!

Well, this feature isn't really something that Qlik supports. The fact that it's possible at all is more of a bonus feature coming with the fact that Log4Net is used within client-managed Qlik Sense Enterprise.
So I don't think you can hold Qlik liable for setup/configuration related problems.

That said, once set up the Log4Net appenders tend to be very stable and just work.
I know Sense environments that have been using this concept for years without any problems, so it's pretty solid.

Regarding Butler, in it's basic configuration it does not require any changes to Qlik Sense.
The basic configuration here means you will be notified (email, Teams, Slack, webhook, InfluxDB, New Relic, Signl4, MQTT, ...) for all failed reloads.

If you want to control on a per-reload-task basis if a particular task should cause a reload failure alert, you do need to create a new custom property in Sense, and then set that CP for tasks that should result in reload failure alerts.
If you have hundreds or thousands of tasks you probably want to control which result in alerts and which don't. Maybe different people/teams should be alerted depending on which task fails too.
If you on the other hand have a smaller Sense environment, the standard setup will probably be fine.

Hi,

Re Qlik's "reliability": well, I would expect a built-in feature for an e-mail alert for a task failure.

Re Butler:

I would appreciate if you'll reference me to the basic configuration: for all failed reloads.

Thanks!

Hi,

Hi @mountaindude,

I have customized my XML file, but still, mails are not sent (Attached below).

I have used the examples you shared , for a basic configuration without Butler:

My question is:

Would I run to the same issue after installing Butler?

I mean, is it something that should be defined in Windows Server?

Thanks!
