Problem with Logstash configuration file using Mongodb input plugin - mongodb

I am getting this error while running the conf file
[2019-10-24T16:17:09,572][ERROR][logstash.javapipeline ][main] Pipeline aborted due to error {:pipeline_id=>"main", :exception=>java.lang.ClassCastException: org.jruby.RubyNil cannot be cast to org.jruby.RubyFixnum, :backtrace=>["org.jruby.runtime.invokedynamic.MathLinker.fixnum_op_equal(MathLinker.java:237)", "java.lang.invoke.MethodHandle.invokeWithArguments(Unknown Source)", "org.jruby.runtime.invokedynamic.MathLinker.fixnumOperator(MathLinker.java:171)", "D_3a_.Elastic.logstash_minus_7_dot_4_dot_0.vendor.bundle.jruby.$2_dot_5_dot_0.gems.mongo_minus_2_dot_10_dot_2.lib.mongo.server_selector.selectable.RUBY$method$initialize$0(D:/Elastic/logstash-7.4.0/vendor/bundle/jruby/2.5.0/gems/mongo-2.10.2/lib/mongo/server_selector/selectable.rb:46)", "org.jruby.internal.runtime.methods.CompiledIRMethod.call(CompiledIRMethod.java:91)", "org.jruby.internal.runtime.methods.MixedModeIRMethod.call(MixedModeIRMethod.java:90)", "org.jruby.runtime.callsite.CachingCallSite.cacheAndCall(CachingCallSite.java:332)", "org.jruby.runtime.callsite.CachingCallSite.call(CachingCallSite.java:86)", "org.jruby.RubyClass.newInstance(RubyClass.java:915)", ... and a lot of other rows
This is my config file

collection=>"Commenti_youtube"
batch_size=>5000
}
}
filter{
}
output{
elasticsearch{
hosts=>["localhost:9200"]
}
}
what's wrong with my configuration file?
Are there other ways to pass MongoDb data to logstash?

sync mongo data to elastic using logstash

I want to sync my mongodb data(local mongodb) to elastic search(local elastic) using logstash-plugin of mongodb
I have install logstash plugin using
bin/logstash-plugin install logstash-input-mongodb .
Then i created a mongodata.conf file in /usr/share/logstash directory.
When I execute the conf file then it shows
--> Sending Logstash's logs to /var/log/logstash which is now configured via log4j2.properties
My config file is:
input{
mongodb{
uri => "mongodb://localhost:27017/reporterDB"
placeholder_db_dir => "/opt/logstash-mongodb/"
placeholder_db_name => "logstash_sqlite.db"
collection => "iam_ms_test"
batch_size => 5000
}
}
filter{
}
output {
stdout { codec => rubydebug }
elasticsearch {

hosts => "localhost:9200"
user => elastic
password => changeme
index => "mongo_log"
document_type => "document_type"
document_id => "%{id}"
}
}
I am getting below lines in logstash-plain.log file

I want the records on my elastic search under `index("mongo_log").
I also want to know the uses of placeholder_db_dir and placeholder_db_name and whats should be these values when we are using mongodb as the input database.
Problem solved! actually the directory opt/logstash was not created . So I manually create the logstash folder under opt. After that i gave Write permission to that directory , so that when we execute the command for logstash then it can create file inside this folder.

How to integrate PostgreSQL with Corda 3.0 or with Corda 4.0?

I tried to configure PostgreSQL as node's database in Corda 3.0 and in Corda 4.0.
I have added following things in build.gradle file. (Testdb1 is Database name. I have tried with postgres also)
node{
...
// this part i have added
extraConfig = [
jarDirs: ['path'],
'dataSourceProperties': [
'dataSourceClassName': 'org.postgresql.ds.PGSimpleDataSource',
'"dataSource.url"' : 'jdbc:postgresql://127.0.0.1:5432/Testdb1',
'"dataSource.user"' : 'postgres',
'"dataSource.password"': 'admin#123'
],
'database': [
'transactionIsolationLevel': 'READ_COMMITTED'
]
]
// till here
}
this part in reference.conf file
dataSourceProperties = {
dataSourceClassName = org.postgresql.ds.PGSimpleDataSource
dataSource.url = "jdbc:postgresql://127.0.0.1:5432/Testdb1"
dataSource.user = postgres
dataSource.password = "admin#123"
}
database = {
transactionIsolationLevel = "READ_COMMITTED"
}
jarDirs = ["path"]
I got the follwing Error while deploying the nodes:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':java-source:deployNodes'.
In node-info-gen.log file it showed the CAPSULE EXCEPTION. Then I updated my JDK to 8u191 but still got the same error.
I have go-through the followings to get the things done. One can get reference from here.
https://docs.corda.net/node-database.html ,
https://github.com/corda/corda/issues/4037 ,
How can the Corda node be extended to work with databases other than H2?
You need to add those properties in node.conf in each of your corda nodes. After you do "deployNodes"
After you add these properties in node.conf file , just run the corda jar . It will automatically start . But before that you need to create the tables (The migration to other DBs is already provided in corda documentation)
I have added following things in .conf file of each node and one referene.conf file. I have given all the privileges for the user postgres which are mentioned in corda documentation.
https://docs.corda.r3.com/node-database.html
(previously I used postgresql-42.2.5.jar file but that didn't work so I used one downgrade version of it postgresql-42.1.4.jar.
one can download jar files from https://jdbc.postgresql.org/download.html )
After deployed Nodes successfully add following things:
dataSourceProperties = {
dataSourceClassName = org.postgresql.ds.PGSimpleDataSource
dataSource.url = "jdbc:postgresql://127.0.0.1:5432/Testdb1"
dataSource.user = postgres
dataSource.password = "admin#123"
}
database = {
transactionIsolationLevel = "READ_COMMITTED"
}
jarDirs = ["path"]
(path = jar file's location) after adding this configuration run file called runnodes.bat

Logstash wont start when adding a match statement in a grok block

I'm having difficulty with starting Logstash.
My logstash.conf looks like this:
input {
beats {
port => "5044"
}
}
filter {
grok {
patterns_dir => ["./patterns"]
match => { "message" => "%{WORD:event_type}\t%{NUMBER:server_time}\t%{NUMBER:market_time}\t%{WORD:instrument}\t%{C_NUMBER:last_price}\t%{C_NUMBER:trade_quantity}\t%{C_NUMBER:bid_price}\t%{C_NUMBER:bid_quantity}\t%{C_NUMBER:ask_price}\t%{C_NUMBER:ask_quantity}\t%{GREEDYDATA:flags}\t%{GREEDYDATA:additional_infos}"}
}
# ... and other stuff here...
}
output {
elasticsearch {
hosts => [ "localhost:9200" ]
index => "%{[#metadata][beat]}"
}
}
Logstash works fine if I comment the match => line. But with it, it does not start, meaning nothing shows up when I run netstat -na | grep 5044 in the container. It is simply not listening on 5044.
And when I try to run Logstash manually by /opt/logstash/bin/logstash --path.data /tmp/logstash/data -f /etc/logstash/conf.d/filebeat-config.conf, I get the following:

What is wrong with the match => line??
I highly appreciate your help.
You're attempting to use a grok pattern, {C_NUMBER}, that Logstash doesn't know about. It doesn't appear to be a standard pattern bundled with Logstash. put NUMBER in that place, and restart logstash.
I was able to resolve the issue by changing patterns_dir => ["./patterns"] to patterns_dir => ["/etc/logstash/conf.d/patterns"].
The match line is referencing a grok pattern that Logstash didn't find because of the relative path to the patterns directory.

logstash-input-mongodb loop on a "restarting error" - Timestamp

I try to use the mongodb plugin as input for logstash.
Here is my simple configuration:
input {
mongodb {
uri => 'mongodb://localhost:27017/testDB'
placeholder_db_dir => '/Users/TEST/Documents/WORK/ELK_Stack/LogStash/data/'
collection => 'logCollection_ALL'
batch_size => 50
}
}
filter {}
output { stdout {} }
But I'm facing a "loop issue" probably due to a field "timestamp" but I don't know what to do.
[2018-04-25T12:01:35,998][WARN ][logstash.inputs.mongodb ] MongoDB Input threw an exception, restarting {:exception=>#TypeError: wrong argument type String (expected LogStash::Timestamp)>}
With also a DEBUG log:
[2018-04-25T12:01:34.893000 #2900] DEBUG -- : MONGODB | QUERY | namespace=testDB.logCollection_ALL selector={:_id=>{:$gt=>BSON::ObjectId('5ae04f5917e7979b0a000001')}} flags=[:slave_ok] limit=50 skip=0 project=nil |
runtime: 39.0000ms
How can I parametrize my logstash config to get my output in the stdout console ?
It's because of field #timestamp that has ISODate data type.
You must remove this field from all documents.
db.getCollection('collection1').update({}, {$unset: {"#timestamp": 1}}, {multi: true})

logstash mongo Db connection issue

I am unable to push data to mongo Db using logstash

mongodb {

}
command used for executing configuration file is logstash -f ./conf/demo.conf

hoping to get a workaround soon. thanks
