Hi,

Hi,

Hi 

 

We wanted to monitor the downloaded AppD Sample App ProgressSQL DB, we followed the instructions in the documents but unable to get it to display any DB metrics or details

 

Understand the default "<AppD Sample App>\build\pgsql\data\pg_hba.conf" has the previlige required. Am I correct ?

 

Any advice is appreciate.

 

Thanks

Re: appdynamic reporting service calls in wrong application tier why?

1) Added image1 file 

 

As you can see i have to end points 

 

user-service/v1/ or user-service/*

 

and 

user-service/v2/.*

 

 

trains tier is only calling user-service/v2 webservice but it showing user-service calls  which is wrong.

 

so i have configured in image2 a regex on user-service-v2 appserver and on user-service app server as in image3 for v1 version. 

 

 

could you please check that. ?

 

2)  dnt understand exactly your question . But we have two service running no different server with name user-service or user-service/v1 and user-service-v2 i.e endpoing user-service/v2/.*

Hi,

 

in first observation, we see defining custom rules will not actually affect how links appear between trains tier and the the tier where web service is served, so custom rule should not discover and is not related here.

 

Regarding links that trains tier making calls only to user-service tier, Can you provide screenshot similar to one below from users-service and user-service2 tier and also agent logs from both the tiers:

agent logs from server itself or from the method you have described ?

 

Also could you help to tell the reason for the unworking of custom rules for this?

Hi ,

 

Agent logs from node dashboard -> agents screen (yes server jvm itself) - use "all logs" option in "request agent log files" popup

 

- Say BT on tier1(trains) is /checkout making Webservice calls to tier2 (user-service) and in tier2 the API is class2.method2(/v2) than as agent supports correlation (link between two tiers is called correlation feature) than if user defined any custom rules on tier2(user-service or user-service2) will not work because it (class2.method2 or /v2 WS call served api on downstream tier) is already part of trains BT snapshot drilldown

Hi.

find the section in UI , agent resolves backend to UI based on hostname and correlation header mapping for which tier it is received if host name is resolved to agents in corresponding tier than this could be the reason or check if any load blancer that will affect the re-direction of load here

 

step1.png

 from screenshots it is clear that only /v1 is resolved to user-service and user-service2 tiers that confirms that load to /v2 is not made or not wrong resolved, i guess we do not required agent logs i believe because /v2 does not looks to be invoked , please be sure that backends are associated to BTs discovered if no BT making /v2 call is part of "Business transactiuons" screen that /v2 is not 

 

we mean /v2 is not resolved as per screenshots you provided we see only /v1 backends resolved to user-service and user-service2 , let us know if any disconnect here

yes i have forward you images after clicking configure backeend for this tier option ..

 

 

 

Regading loadbalancer(checked lb logs too and nginx logs too as forwarding to correct service)  it all good its forwarding call to user-service/v2 to user-service and user-service/v2 to user-service-v2.

 

but in appd display is mix of both service ....

 

 

i am not able to find option to download logs for UI

your answer :-  from screenshots it is clear that only /v1 is resolved to user-service and user-service2 tiers that confirms that load to /v2 is not made or not wrong resolved

 

 

 

 

could you forward me the screenshot where you could see that /v1 is resolving to user-service-v2 also . ?
