subject:"Re\: \[Neo4j\] Neo4j REST server's log files"



Hi David,

Thank you for getting back to me!  
Finally I can make it work by changing the log level from INFO (by default) to 
FINEST in the logging.property.

I have a question for you though. Currently my project have a problem with 
uploading data to the store. I created only 1 index for the whole application 
and the node name as the key. Several nodes in different ontologies have the 
same names.  So when an ontology is uploaded to the store and has a node that 
its name has been already in the index (by previous ontologies) this node is 
not created in the graph of this ontology. My app can upload a number of 
ontologies and graphs are created successfully for each ontology in the store. 
However when the process uploads the 9th ontology the store does not respond 
and it seems busy with some internal process like looking up the node in the 
index or something else. I'm stuck and don't know the cause of the problem. Do 
you have any clue or suggestions?

Appreciate your help!

  I don't understand much your question. However, in my Restlet

 a NoHttpResponseException: The target server failed to respond.
  I'd like to see what causes the problem inside Neo4J. Unfortunately both

Re: [Neo4j] Neo4j REST server's log files

Hi Andrew,

Good to hear that you got the logging sorted out.

Regarding the actual issues, it sounds like you're describing two different
things. One is that you index ontology nodes in one global index and
therefore run into conflicts. The other is that the upload appears to stall
for some reason.

Regarding the global index, did you intend to design the system that way,
or do you really want a separate index for each ontology? It sounds like
that would be reasonable.

As for the stalled upload, a thread dump during the slow processing would
be most helpful. On a Linux system, you can capture that by doing kill -3
pid on the Java process. It should then go to console.log.

Thanks,
David

I'll try it. Thanks!

Re: [Neo4j] Neo4j REST server's log files



Hi David,

I increased the memory settings in neo4j-wrapper.conf as below
# Initial Java Heap Size (in MB)
wrapper.java.initmemory=30

# Maximum Java Heap Size (in MB)
wrapper.java.maxmemory=1024

However the same problem is still happening. I attach the thread dump to this 
mail. I appreciate it if you tell me what's wrong based on the thread dump.

Thank you!

Re: [Neo4j] Neo4j REST server's log files

Hi Andrew,

I don't see anything running in that thread dump. No threads are processing
requests. Are you sure it's taking a long time, or is it maybe finished?
Try capturing the thread dump exactly when you experience slowness. I'd
also suggest bumping the initial heap to at least 512MB or something like
that. How much RAM do you have? How much data are you inserting?

Thanks,
David

   messages.log and neo4j.x.x.log do not show run time processes.
BTW, when I start up the server the neo4j.x.x.log shows

Re: [Neo4j] Neo4j REST server's log files



Hi David,

The total size of files stored into the db when the problem happened was only 
800KB. My RAM is 4G. 
I ran the kill command when the problem happened because it just stopped and I 
did not notice slowness.

I will increase the heap to 512MB and test again.

Thanks,
Andrew

Hi Andrew,

I don't see anything running in that thread dump. No threads are processing
requests. Are you sure it's taking a long time, or is it maybe finished?
Try capturing the thread dump exactly when you experience slowness. I'd
also suggest bumping the initial heap to at least 512MB or something like
that. How much RAM do you have? How much data are you inserting?

Thanks,
David

 I increased the memory settings in neo4j-wrapper.conf as below

 Hi Andrew,

 Good to hear that you got the logging sorted out.

 Regarding the actual issues, it sounds like you're describing two different
 things. One is that you index ontology nodes in one global index and
 therefore run into conflicts. The other is that the upload appears to stall
 for some reason.

 Regarding the global index, did you intend to design the system that way,
 or do you really want a separate index for each ontology? It sounds like
 that would be reasonable.

 As for the stalled upload, a thread dump during the slow processing would
 be most helpful. On a Linux system, you can capture that by doing kill -3
 pid on the Java process. It should then go to console.log.

 Thanks,
 David

  I have a question for you though. Currently my project have a problem
 with
  uploading data to the store. I created only 1 index for the whole

  ontologies have the same names.  So when an ontology is uploaded to the
  store and has a node that its name has been already in the index (by
  previous ontologies) this node is not created in the graph of this
  ontology. My app can upload a number of ontologies and graphs are created
  successfully for each ontology in the store. However when the process
  uploads the 9th ontology the store does not respond and it seems busy
 with
  some internal process like looking up the node in the index or something
  else. I'm stuck and don't know the cause of the problem. Do you have any

Re: [Neo4j] Neo4j REST server's log files

2011-11-09 Thread Mattias Persson

You want to look at data/log/console.log and data/log/neo4j.0.log (I think
it's called).

Peter, messages.log isn't for users, it's mainly for forensics/debugging
where a neo4j dev can get info by looking at.

Neo4j is rather light on the logging in general.

Re: [Neo4j] Neo4j REST server's log files



Hi Peter,

I don't understand much your question. However, in my Restlet application I 
have a logging service using Java log to record all processes in my app. My 
problem is that I upload 20 ontologies and after serveral ontologies the Neo4J 
stops responding my REST request. It seems busy with some index lookup process. 
Consequently my app throws a NoHttpResponseException: The target server failed 
to respond.
I'd like to see what causes the problem inside Neo4J. Unfortunately both 
messages.log and neo4j.x.x.log do not show run time processes.
BTW, when I start up the server the neo4j.x.x.log shows
