Ignore valid 5xx scenarios

[payal_bid]

Hi Team,

We came through few expected/valid scenarios of 5xx errors where we don’t want any error count against that but unfortunately they are also being captured on DT .

We tried to configure the system by following the provided link, which involved creating a rule to ignore the "good" responses. However, the configuration did not work out and we are still getting those errors as 5xx.

Please advise on this. 

Thanks.

Hi,

Could you please past your configuration here?

Hi Malaik,

PFB the snapshots.

You should exclude the exact HTTP 500 code from the first line.

But remember, here it will applied for all services in your environment.

If you want to do it for a specific services(s). you should apply it on the service(s).

Hi Malaik,

We have made the changes as you suggested, but still we can see the 503 http responses being captured. Attached the snapshot of last 2 hours requests for you reference .

Please let us know if any changes are required.

Ok,

This method will only exclude the http code from the list of errors but the request will remain captured.

Are you looking to not capture the request (trace) at all? if yes, I'm not sur that this is possible.

I'm thinking of a workaround that can be used, by creating web request naming rules, to rename all requests with status 503 to be named as the http status itself {HTTP-Status} (this is in case the original request name is not required and will be ignored), then mute the request with name 503.

After you mute a request,

Automatic alerts for the muted request will no longer be generated.
The muted request will be excluded from the service charts.

Hope you are doing wee @Mohamed_Hamdy 

I didnt suggest this for 2 reasons:

1- you should do it service by service (or via API) which is a huge work.

2- Not only http code 503 should be ignored but as requested all 5xx.

I think this should be reviewed (i didnt ask the why for this decision), but ignore all 5xx is not good for the health of the applications we can miss an important issues.

Hi @Malaik ,

I'm fine and I hope you are doing well too.

Of course, I agree with you that ignoring all 5xx is not good and not recommended, I've just added this workaround for specific HTTP status in specific cases. and on a certain service this will be easy, and using API globally is not that hard to do as well.

in the end, Dynatrace has multiple ways to configure things if it's not straightforward configurations.
