Hello @steven-matison thank you for your detailed explanation. I also narrow this down to resource scarce issue. Yes it's currently single node. Could you please help me understand how to have cluster you mentioned above and like how to do it and what all is required for that.

Hello Team We have an increasing number of applications being added to our NiFi server. Now the nifi has got too slow that it won't load the home page or when we click a process group then it won't open despite browser url showing the process group id as if page should have gone there. Also the apis we have implemented using HandleHttpRequest return Socket Timeout error. Please note these were working fine earlier. What should we do?

Hello it seems templates which existed in NiFi 1 is removed in NiFi 2.8.0 How to import the flow definition to the new instance? Earlier we were able to move nif flow to new instances of NiFi using templates. Any screenshot will be helpful for NiFi 2. Currently I can only download flow definition by right clicking a process group. Some article suggested Registry. Do we have any other approach like nifi 1 where we used to browse and upload.

Thank you @steven-matison for suggesting possible solutions. Could you please elaborate as I am new to these terms. I used to have my apis in Java/Spring Boot secured via OIdc/Oauth2 or even Basic for test apis earlier. We used to have libraries in Spring Boot to configure OIDC.

Hello can we secure our apis in nifi? Suppose we create nifi flow which utilises HandleHttpRequest for exposing an api. How to secure this? Is it possible to have Oauth2/Oidc?

hello in the logs above I don't see any log which describes LogAttribute (the screenshot you have posted above says it is a LogAttribute processor) being started or stopped. Also anyway to know which user did this

Hello we have single user based NiFi but in reality around 15 to 20 people use that instance. How to know who added a process group or stopped a processor and at which point of time was that processor stopped? Do we have any IP getting recorded or anything like that? Is it possible in NiFi having OIDC/Oauth2 based authentication that which user added/removed something?

Hello Thank you for your detailed steps. What all should discovery url (https://idp.company.com/.well-known/openid-configuration) generally return in the response?

AlokKumar · ‎05-11-2026

Hello I need help to setup oidc based login mechanism for NiFi. I came across this article https://docs.cloudera.com/cfm-operator/2.10.0/configure-nifi-cr/topics/cfm-op-configure-nifi-cr-oidc-auth.html but I want to know how to do it for some provider other than Keycloak. I have an internal provider. Also when I read this article I saw some terms like Discovery url and "The clientID and clientSecret fields are provided to NiFi in a Kubernetes secret. Create that secret with the following command: kubectl create secret generic oidc-client-secret --from-literal=clientID=[***YOUR CLIENT ID***] --from-literal=clientSecret=[***YOUR CLIENT SECRET***] I am quite new to these terms and wanted to know how to do it in NiFi. Is kubernetes required? I have installed both NiFi 1.23 and NiFi 2.8 on a simple machine.
