Full stack monitored application / host does not show outgoing connection to my ldap.

[gilles_tabary]

Hello.

I have an application running on Linux VM host, happily full-stack monitored, technology looks supported. Though I don't see in Dynatrace the outgoing connections either from app nor from VM host it is running on, to my ldap service.

I suppose I should see them kind of at code level or at requests level ? Or am I mistaken because say it is ldap:// protocol as opposed to http[s]:// protocol ?

Any trick known ?

Regards.

Hello @gilles_tabary 

Regarding the highlighted concern:

• As long as the servers are monitored in full-stack monitoring mode, you will be able to get insights regarding the infra and code-levels as well.
• You well be able to view the calls to the LDAP Services under requests to un monitored hosts, in case the LDAP Servers are not monitored in Dynatrace.
• If the LDAP Servers  are monitored using DT Oneagent you will get full visibility into LDAP Services.
• You can see the full service calls through the service Flow on the services level, on the host level you can inspect the process group connections as well.
• https://docs.dynatrace.com/docs/observe/applications-and-microservices/services/analysis/service-flo...

Regarding LDAP monitoring you have option through the Hub: 

• https://www.dynatrace.com/hub/detail/active-directory-services/
• https://www.dynatrace.com/hub/detail/active-directory-extended-monitoring/
• https://www.dynatrace.com/hub/detail/ldap-synthetic-1/

Hoping it helps.

Hi. Thanks. You perfectly got the question 🙂👍

Mystery:
I don't see the Service Flow as documented @ https://docs.dynatrace.com/docs/observe/applications-and-microservices/services/analysis/service-flo...
I don't see host outgoing connections to my LDAP.
I don't see PG / PGI outgoing Process connections to my LDAP.
I went to inspect PG services > requests > outgoing > trace > service flow : nothing visible.

The ticket I opened with the support is not helping for now. For now I am baffled.

Hi @gilles_tabary 

Kindly ensure:

• The Process group deep monitoring is enabled on the target process groups.
• The process groups technologies are supported or not to avoid long-time troubleshooting the issue.
• The oneagent features regarding these technologies are enabled properly && required service restart is conducted correctly.
• The Platform and monitoring components "Cluster nodes, Oneagents, ActiveGates" are up to date.

Ensure no blocking for the Dynatrace headers from the Firewall or network sides: https://docs.dynatrace.com/docs/observe/digital-experience/web-applications/initial-setup/firewall-c....

Hoping it helps.

BR, 

Peter

Have you checked if the processes are fully monitored in your case. For example in the screenshot below, some processes need a restart[yellow icon] and some of them have other issues[one with "i" icon]

Thanks for feed back / idea.

That's the crux of my issue : my host is reported full-stack. We rebooted host. My PG is reported as instrumented fine (no warning icon, no info icon). AFAIU the technology of my PG is known and supported by OneAgent full-stack / injection function.

Maybe I am missing something more conceptual, which would explain I cannot see these connections.

Hi.
It turns out ldap:// connection protocol is not yet monitored by Dynatrace (information obtained from support).
There is an RFE Request to add capabilities to monitor LDAP protocol.
