Hello. Yesterday I noticed the mechanism of purging old files in content repository had not worked off. It was configured 12 hours, 20% of disk space, but it took about 80% of content repository, and files were of 14 days old. Any ideas why could this happen? Btw after restart of nifi purging the content repo worked and everything was ok. Who have faced such a problem?

If you have your metric as an attribute you can choose bin algorithm and specify correlation attribute by metric name. Hope it will help

I've seen the problem you describe with getfile processor when I used it with nifi deployed on Windows OS and the directory I listed had very large number of recursive subdirectories. In source files of nifi 1.3 or 1.4 I noticed there was a code replacing listfiles with DirectoryInputStream methods, but later it was removed

As for the second question you may need processors operating with map cache to compare previous cached value of pressure with the recent one

<file>${org.apache.nifi.bootstrap.config.log.dir}/nifi-app.log</file> Until 1.7.0 this string in logback.xml was commented. Uncomment it and it will be ok

Thanks for the answer. But I got rid of extracttext cause I am dealing with thousands of rows. I 've been using it since 0.6.1 version until 1.2. Moreover I don't know how many params p1, p2 there could be and its order. So I consider using Updaterecord or maybe ForkRecord in some way. Any help is appreciated.

The data is in the below format: 1;p1:"123",p2:"234";r1 2;p1:"333",p2:"444",p3:"555";r2 3;p2:"666",p5:"888";r3 p1, p2, p3 and so on could be a great variety of params. So in the output I'd like to have a structure in csv of such kind: 1;p1;123;r1 1;p2;234;r1 2;p1;333;r2 2;p2;444;r2 2;p3;555;r2 3;p2;666;r3 3;p5;888;r3 How to implement it with standard record processors? Thanks.
