Hi,

I've created a filter to throttle issolatelly messages from several servers. When the systems receives 50 equal messages from an specific server i add a tag "e-mail".  
Output sends e-mail when a message have this tag. However, It send 3 e-mails insted of sending one.

I don't why, is there something wrong in my config?

> throttle {  
> before\_count =\> 24  
> after\_count =\> 26  
> period =\> 300  
> key =\> "[%{host}][ws\_bingobombo]"  
> add\_tag =\> "error\_ws\_bingobombo"  
> }  
> if "error\_ws\_bingobombo" not in [tags] {  
> mutate {  
> add\_tag =\> ["email\_ws\_social\_error"]  
> }  
> }

Thanks

Hi warkolm,

> if "email\_ws\_social\_error" in [tags] {  
> email {  
> to =\> "addresses"  
> address =\> "my server ip"  
> body =\> "Error ... [HOST:%{host}]--[TIME:%{time}]"  
> domain =\> "my domain"  
> from =\> "[servidor.logs@domain.com](mailto:servidor.logs@domain.com)"  
> subject =\> "[%{host}] - Error"  
> via =\> "smtp"  
> }  
> }

I don't understand why is sending 3 e-mail, within the same time (2 seconds between them)

Hi Marc,

Throttle condition which you had written is not throttling 24th, 25th and 26th events, therefore as per your condition if "error\_ws\_bingobombo" not in [tags] it will generate 3 email alerts for those three events.

If you wish to generate single alert change count as before\_count =\> 24, after\_count =\> 24.
