Root cause Analysis Not showing up

[mani300115]

Hi Experts,

We have requirement to show correlation and root cause analysis detected by Dynatrace Intelligence. As part of testing, we created below

1) Created http synthetic monitor with URL (IIS webserver)

2) IIS app pool process availability is monitored

3) It generates problem for above both , but dynatrace intelligence is not showing any root cause. We are expecting HTTP global outage should show IIS process down as root cause, But not showing up

4) we created web application in RUM and assigned to this synthetic monitor too

Anyone pls suggest, what we are missing so that we can show auto correlation and root cause?

Hi @mani300115 

Dynatrace can only link entities that are actually connected in Smartscape topology, not just ones that fire around the same time. It needs the chain Synthetic Test →Web App -> Service → Process Group Instance → Host. If that chain isn't there, you get two separate problems instead of one root-caused one.

Most Likely Missing Pieces
OneAgent must be Full-Stack mode (not Infra-Only) on the IIS server
Service auto-detection must be active — confirm your IIS service appears under Services in Dynatrace
Smartscape must show the full dependency chain from the monitored URL down to the process/host

Thanks,

Sujit

Thanks for your answer

We have IIS server monitored in full stack and can see full dependency in smarscape classic(not in smartscape grail)

We created  new application and assigned it to synthetic monitor, but still we can't see root cause

Hi @mani300115 

Thanks for the update.

A few things I'd suggest checking:

• Is the Synthetic monitor generating distributed traces that reach the IIS service?
• Can you see the IIS service in the trace/service topology when opening View traces from the Synthetic monitor?

Steps:

1. Open the Synthetic monitor -> View Details -> click View traces.
2. Select one of the transactions generated by the Synthetic monitor.
3. Verify whether a service is detected for the request by clicking View service.

If the Synthetic monitor isn't linked to a detected service, Davis may not have enough dependency information to establish a root-cause relationship.

• on next page, select the transaction and see the view service
  
  

  

Thanks,
