Force Elastalert to send mail in a specific font

[Alexwii]

Hello everyone,

Thank you so much for Elastalert, it's beautifuf and very powerful.

I have a problem, when I want use "summary_table_fields" my mail look like this:

And the problem it's that the font is not appropriate for the table.

It's not possible to specify at Elastalert to use a font like consolas ?

Thank you so much for your answer

In my case Elastalert sends emails in the Text mode and i don't think you can force a specific font there.

• See if you can change to html mode then you can set the font with css (you could do this with a custom alert https://elastalert.readthedocs.io/en/latest/recipes/adding_alerts.html)
• Check if your email client has a setting for a default font. (this change will have to be done on all receivers)

I will am create an alert in HTML, thank for your answer !

[AnderssonPeter]

@Alexwii if you do manage to create a html alerter please share it here in case someone else gets the same problem!

[Alexwii]

[Alexwii]

[Alexwii]

@Alexwii

Did you manage to get the proper format of the summary_table_field in email output? I'm also experiencing the same issue. My email output looks ugly, also I get more blank spaces in the bottom of the outlook email.

[Alexwii]

Yes I fix it.

But I have not the time for share it here, because I need to write a documentation and I have a lot of work this month.

Maybe end of august... I'm sorry for that.

@Alexwii

Thanks for the update. Meanwhile, could you please share at least the steps to get the proper output with creating an alert in HTML

For those looking for a decent table in email output, you can import the below alerts.py and give it a try. It gives a pretty table output. It uses the python from prettytable import PrettyTable https://github.com/qianghaohao/elastalert/blob/master/elastalert/alerts.py

Thanks to @qianghaohao for helping this accomplish.

@sathishdsgithub thanks so much... will look into it. Really looking for how to change text, add logos, etc. Basically how to make the e-mail alert look good, so something that uses HTML code and not plain text.
