No conf folder on installation of 2.01 on win 7

[Modi Tamam]

Hi,

After installing the 2.0.1 version of Neo4J, I can not find the conf folder.

Can someone please help me here?

[Mark Needham]

Hey,

AFAIK there isn't a conf folder - the properties file (neo4j.properties) is in the directory where Neo4j is installed. I'm assuming you installed it using the installer so you should be able to find the location of the file from the UI.

What were you wanting to configure?

(unfortunately I don't have my machine which has a Windows VM on me so I can't check for you!)

Cheers

Mark

Hi,

I'm trying to see what are the queries that I execute, transactions and any database activity that my code (Java - Spring data framework) performs under the hood.

Any assistance will be appriciated.

Does this thread help for cypher logging? http://stackoverflow.com/questions/8958583/is-there-a-way-to-log-queries-on-neo4j-like-hibernate

[Modi Tamam]

If I understand it correctly, this thread is about enabling the query logs on the application side and not on the database logs.

What I wanted is to see on is the databse logs (same like you can find on MySQL, MongoDB etc.)

Do you mean error/debug logging? You can see that in the messages.log file.

If you mean transaction logs then you can look at nioneo_logical.log.1, nioneo_logical.log.2, nioneo_logical.log.v* - there's a class in the kernel called DumpLogicalLog which you can use to read them in a textual format. 

[Modi Tamam]

I'll elaborate a bit, I have a flow ( on my code ) and I want to see all of the interactions (queries, opening/closing transactions etc) with the database and I want to see it on the databse's logs.

Regarding the messages.log file, what's in there, where can I find it?

What do you mean by "DumpLogicalLog which you can use", how can I use it?

Most of that logging is too verbose for normal use so it's disabled by default. I'm not sure whether we even log when transactions open/close even in debug mode...I'll check.

If you're using cypher then one cypher statement happens within a transaction if that's what you're interested in.

I'll check how to enable logging of cypher statements. That is also disabled by default - we used to have it turned on but it ended up filling up people's disk in no time.

It will be in the same folder where the Neo4j store files are...if you used Neo4j desktop then it'll be something like c:/Users/you/Neo4j/. 

> What do you mean by "DumpLogicalLog which you can use", how can I use it?

I don't think that's relevant based on your clarification of what you want to do. It's a lower level tool for seeing the commands used in transactions.

Hi Mark,

I'm still waiting for your answer.

I'm using SDN-3.0.0 and connecting to a standalone Neo4J db over REST.

I want to add additional details, I'm using SDN - 3.0.0.RELEASE, and what I want is to get an indication about the queries that SDN sends/executes 

on the database server .

I set the 

org.neo4j.server.http.log.enabled=true

On the neo4j-server.properties file.

And I see that there is another property beneath it:

org.neo4j.server.http.log.config=neo4j-http-logging.xml

So, where is that file? and where are the logs are written to?

[Mark Needham]

Hey,

Sorry, I've actually been trying to figure out how to get HTTP logging to work but I haven't been successful yet. I debugged the code all the way down to where the logback config gets passed to Jetty and it all looks fine but then nothing gets logged!

Maybe you can use SDN's logging instead? http://stackoverflow.com/questions/8958583/is-there-a-way-to-log-queries-on-neo4j-like-hibernate

SDN query logging should be enabled by setting these loggers to DEBUG
in your client app logging config

for embedded: org.springframework.data.neo4j.support.query
for remote/REST org.springframework.data.neo4j.rest

[Modi Tamam]

Will I be able to view the REST calls for opening/commiting transactions ?

[Michael Hunger]

There are no transactions over REST

Sorry, but I thought that this page describes the transactional REST API, obviously I was wrong.

So, what did you mean by writing:

The Neo4j transactional HTTP endpoint allows you to execute a series of Cypher statements within the scope of a transaction. The transaction may be kept open across multiple HTTP requests, until the client chooses to commit or roll back. Each HTTP request can include a list of statements, and for convenience you can include statements along with a request to begin or commit a transaction.

[Michael Hunger]

It does, but that's not used yet by SDN. SDN was initially built on
the embedded java-API (long before Cypher) and one of the goals for
the future is a complete rewrite of the internals to replace that
Java-API use by a cypher driver + Java-object graph mapper +
SDN-integration, but right now there is no timeline or concrete plans
for that.

[Modi Tamam]

I see, so, correct me if I'm wrong, but what you are saying, is that at the moment,

SDN is not the recommended solution for communicating with a remote Neo4J instance.

[Michael Hunger]

Yep. You can do it for demo purposes and if you use a lot of cypher queries on your repositories, but in general the fine grained, chatty operations over the wire are too much overhead.

Michael

[Modi Tamam]

OK, we'll disscuss the SDN production-unreadiness and the alternatives on another thread.

Let's go back to this thread initial issue, how do I configure the db, so that I'll be able

to see all of the REST requests to the database?if it's possible...

[Michael Hunger]

Probably easiest way is to add a proxy like fiddler in between.

Currently the java-rest-binding doesn't have custom logging, but you
should be able to enable logging in jersey-client with setting

com.sun.jersey to finest / debug

Didn't try it though.

Thank's a lot .
