We are new adopters to ELK and coming from MS background. However, we are trying to switch to the open source world.
We've been already using MongoDB with a new system and we're also trying to use ELK to analyse the data from MongoDB. We found the following unofficial driver:
https://github.com/phutchins/logstash-input-mongodb .
The configuration file contains :
input {
mongodb {
uri => 'mongodb://localhost:27017/my-logs?ssl=true'
placeholder_db_dir => '/opt/logstash-mongodb/'
placeholder_db_name => 'local.db'
collection => 'jsonsample'
batch_size => 5000
}
}
filter {
}
output {
elasticsearch {
host => "localhost:9200"
}
stdout
{ codec => json }
}
Note : we don't know what does placeholder_db_dir means .
The cmd result when typing "logstash -f path/to/config/file.conf" is :
Sending Logstash logs to C:/logstash-5.0.0/logs which is now configured via log4j2.properties.
[2016-11-10T14:45:19,801][ERROR][logstash.agent ] fetched an invalid config {:config=>"input {\n mongodb {\n \n uri => 'mongodb://localhost:27017/my-logs?ssl=true'\n placeholder_db_dir => '/opt/logstash-mongodb/'\n placeholder_db_name => 'local.db' \n collection => 'jsonsample'\n\t batch_size => 5000\n }\n}\n\nfilter {\n \n}\n\noutput {\n elasticsearch {\n host => "localhost:9200"\n }\n \n stdout\n { codec => json }\n}\n", :reason=>"Couldn't find any input plugin named 'mongodb'.
