The MiNiFi Java agent builds the nifi.properties file from default values and the ones exposed in the config.yml. To override the default values not exposed in the config.yml, a property must be added to the config.yml in the NiFi Properties Overrides section.
For example, content archiving is disabled by default. To enable this, add the following in the config.yml file:
NiFi Properties Overrides: {
nifi.content.repository.archive.max.retention.period: 1 hour,
nifi.content.repository.archive.max.usage.percentage: 10%,
nifi.content.repository.archive.enabled: 'true'
}
Then, save the config.yml and restart the agent. If you look at the nifi.properties file, you will see the updated values.
NOTE: This is a known issue (internal bug CEM-967) when using the Edge Flow Manager (EFM) to publish flows to the Java agent. When a new flow is published, the agent does not retain the overridden properties. Hence, the properties have to be re-entered manually and then the agent has to be restarted.

@Renew I ran a test with one of the MiNiFi agents and I was successful in tailing a symlink in Windows, (C++ 0.7.0). Which agent and what version of the agent is being used?

@mahieddine It sounds like that either the VM will need more resources to run the current flow design or change the flow to require fewer resources. Once there are OOM errors, then all sorts of other issues could occur.

@Sush217 The easiest way to get the templates would be to restart NiFi and then download the saved templates from the NiFi flow. Otherwise, you will have to manually extract the templates from the flow.xml.gz file, which is prone to errors.

@mbaid How can I schedule a NiFi processor to run only when it receives the first flow file of the day? If you know the time of the first flow file, you can configure a processor with a Scheduling Strategy of CRON driven. If you don't know the time of the first flow file, the solution would be different depending on which processor would be the first processor in the flow. The processor can ignore all subsequent flowfiles. Does this mean the subsequent flow files can be removed?

@ksha The URL looks incorrect: t3://testurl.com:39101. Is the name of the sever where the WebLogic server is running testurl.com? Is the port 39101 correct? The default port for WebLogic is 7001.

@burakongun In my experience with the msi file, I've had to do a couple of steps before running it. First, make sure there are no blanks spaces in the path to JAVA. Something like C:\Java Second, I created a local user that was used to run MiNiFi. I also gave this user Administrator privileges. I hope this helps.

@AndyAjram Did you install NiFi as a service in Windows? If not, you should be able to download the msi file for the version of NiFi from the public repo. What version of NiFi is being used?

@minaa_khalili I see the same behavior in my testing. This was a known issue with the ReplaceText processor. The only way I can get it to work the same is to insert a line return in between the regex's. Example image below: The issue was resolved in the next release of MiNiFi.

@johnmteabo You're correct, the PublishJMS processor is not included in "out of the box" MiNiFi. You must copy over the nar with the needed class: org.apache.nifi.jms.processors Keep in mind, you will also have to copy over the nar with the Connection Factory Controller Service which is a required property for that processor. The two nars should be: nifi-jms-cf-service-nar-version-number.nar nifi-jms-processors-nar-version-number.nar The version number must match the version numbers of the current nars in the MiNiFi lib directory.
