Thanks Joe and Bryan. The setup is little more involved but I was able to
get ConvertRecord running with a grok reader and a json writer. And I can
confirm that setup splits records as expected by newline. Nice touch to
have multiple records contained in the same flow file! Thanks for the tip

Hi there,
I've been playing with the ExtractGrok processor and noticed I was missing
some data that I expected to be extracted. After some investigation, it
seems that ExtractGrok extracts only the first line of the flowfile
content, and ignores the rest.
Is this expected behavior? I should be

Jeff,
This was a new installation so I actually hadn't set up any flows yet. NiFi
wouldn't start immediately after installation (before I could configure any
flows) because the system had too little ram. The 1.1GB figure is private
(RSS) memory usage, which exceeded the 1GB instance limit (and
Hi everybody,
I recently started up a new cloud Linux instance with 1GB of ram to do some
quick tasks in NiFi. I noticed NiFi kept dying without much information in
the logs - it just seemed to stop during startup.
Eventually I realized the system was running out of memory and OOM killing

Just to add slightly to this question:
> Will ListS3 keep state correctly here for all 3 subdirectories?
The answer is yes - ListS3 will keep state correctly for all 3
subdirectories. For example, if you setup a new ListS3 processor, give it a
bucket and prefix, and start the
No problem at all, glad you got it sorted out! The delimiter functions more
like a filter, where all subkeys below the prefix with the delimiter are
ignored.
A good explanation is found here:
http://docs.aws.amazon.com/AmazonS3/latest/dev/ListingKeysHierarchy.html
And a quote from that link:
Laurens,
Sounds like you had some success using the prefix
"AWSLogs//CloudTrail/ap-northeast-1/2017/07/03/", is that right? If
so, when you right-click and choose "View State", is the timestamp and
latest key name stored?
Try changing the prefix to
"AWSLogs//CloudTrail/ap-northeast-1/2017/07/",
Hi Laurens,
What NiFi version are you running? There was an issue where ListS3 would
spin like that on buckets with many files, but it was fixed in version
1.1.0 IIRC.
Hope that helps,

Jim,
Also keep in mind that as an object store, S3 uses "directories" only as a
grouping concept, and not as a hierarchal storage mechanism. That's why the
initial PutS3Object doesn't fail with a new "directory". See

Thanks all for your help! Once I built the latest master, specifying 'UTC'
as the second argument of toDate() did the trick:
${timestamp:toDate("-MM-dd'T'HH:mm:ss'Z'", "UTC"):toNumber()}
Much appreciated,

Oleg,
A unix epoch timestamp is explicitly defined as the number of seconds (or
millis) since Jan 1 1970 *UTC*, not any local timezone. Here's an example
ruby expression from both systems correctly returning the 1487804483000
value despite their timezone settings:
irb(main):003:0>
Hi,
I recently noticed some issues with time parsing in the expression language.
On my Linux server configured with UTC time, using UpdateAttribute to
convert a timestamp value to millis works as expected.
Attribute name: timestamp
Sample value: 2017-02-22T23:01:23Z
UpdateAttribute is
I agree. There are also one-time actions like processing data inside an
existing bucket for which a ListS3 processor would be well suited.
Thanks for all the encouraging feedback on the blog post!
