The answer is NO - but the Apache Team is looking in developing this functionality as per @apiri answer below.
I have a Apache NiFi Server i use to collect data from multiple source (Windows/Linux) where i have minifi on them setup.
On each edge minifi flow configuration i have a self-control PG that collect minifi internal statistics such as instance:health,stats,bulletins.
Where the call look like this
Eg
#/bin/bash
/opt/minifi/bin/minifi.sh flowStatus instance:health,stats,bulletins | tail -2 | head -1
So far so good - i get this data extract the json -> create an Influx Call and push it into a InfluxDb that is then displayed into Grafana, this has alerts when one Egde goes off or there is a high queue, or even the Garbage Collector on the minifi edge stats bla bla.
Question:
How do i do this in Windowzzzzz ? i am going crazy.
The .bat executables are not responding to any of the flowStatus options
I managed to do it thru Cygwin but i don`t want to setup Cygwin in all egdes.
Any ideas here on how i can achieve this ?
thanks
Here is small demo of what i am trying to do:
All the actions are done on a Windows Server
Working - this is done from MobaXterm client installed on the Windows Server. ā

Not Working - this is done using PowerShell as Administrator and making use of the run-minifi.bat

The JAVA_HOME environment variable is not defined correctly.
Instead the PATH will be used to find the java executable.

This was certainly an oversight on our behalf and we do not have explicit support for invoking the flowStatus from one of the bat files.
I have created an issue to make sure this gets addressed for our next release, located at https://issues.apache.org/jira/browse/MINIFI-430.
The workaround in the interim, also listed in the ticket:
The current workaround would be to edit/duplicate one of the bat files and modify the BOOTSTRAP_ACTION to be flowStatus and support handling additional arguments. For example, this line in run-minifi.bat (https://github.com/apache/nifi-minifi/blob/e9e9179f8d359bc30aa61c60f5a35441bfb7513a/minifi-nar-bundles/minifi-framework-bundle/minifi-framework/minifi-resources/src/main/resources/bin/run-minifi.bat#L48)
Thanks for bringing this to our attention.
Update: This has been incorporated into the master branch of the repo (https://github.com/apache/nifi-minifi/commit/a08bc9a23e7274fce18ae4e281e1105d97962f99) and will be available with the 0.5.0 release.
