Logstash & Dashboards

Reporting Integration

The Limina container can be configured to send reporting metrics to a logstash server. To enable this feature, the following environment variables can be added to the docker run command:

Variable Name	Description
`PAI_ENABLE_REPORTING`	Enables Reporting to a Logstash Server
`LOGSTASH_HOST`	The Logstash server’s host info
`LOGSTASH_PORT`	The port of the Logstash server
`LOGSTASH_MONITORING_PORT`	The monitoring API port of the Logstash server.
`LOGSTASH_TTL`	Sets the time to live value (in seconds) of the data queued for logstash. Data will be lost if the queued data is not sent successfully before the ttl value.
`PAI_REPORT_ENTITY_COUNT`	Enables entity counts (per piece of text deidentified) to be added to reporting

To run a container with these settings, the following command can be used:

Docker Command

docker run --rm -p 8080:8080 --mount type=bind,src=$PWD/tests/fixtures/licenses/license.json,dst=/app/license/license.json -e PAI_ENABLE_REPORTING=true -e LOGSTASH_HOST=http://hostname.org -e LOGSTASH_PORT=50000 -e PAI_REPORT_ENTITY_COUNTS=true -it deid:image-name

The Logstash pipeline that the data is being sent to must be configured to able to accept JSON objects. A sample pipeline configuration that allows this would be:

Pipline Config

input {
	tcp {
		port => 50000
		codec => json_lines {}
	}
}
output {
	elasticsearch {
		hosts => "elasticsearch:9200"
		user => "${LOGSTASH_USER}"
		password => "${LOGSTASH_PASSWORD}"
	}
}

What is Being Sent?

When PAI_ENABLE_REPORTING is enabled in the container metering records will be sent to Logstash in batches, at 5 minute intervals. All records include the following fields:

Field Name	Description
`privateai.SessionId`	A unique id that relates all metering information sent in the interval
`privateai.Accuracy`	The accuracy used in the requests
`privateai.ProjectId`	The project id of the request (the default value is main)
`privateai.Synthetic`	Boolean value indicating if synthetic data was used

The following meters are currently being used (one record per meter, per project ID):

Field Name	Description
`privateai.api_calls`	The amount of api calls sent in the interval
`privateai.api_chars`	The amount of characters processed in the interval
`privateai.api_words`	The amount of words processed in the interval

If PAI_ENABLE_PII_COUNT_METERING is enabled in the container, meters for each entity found will also be sent. These meters contain the following fields:

Field Name	Description
`privateai.pii-count`	The amount of times the entity was found to be the best label in the interval

If PAI_REPORT_ENTITY_COUNTS is enabled in the container, a record of the entities found and their counts for each unit of text processed will be sent. e.g.

Metering Records

privateai.NAME: 2
privateai.OCCUPATION: 1

would indicate that in a unit of text processed, the entity NAME was the best label two times, and OCCUPATION was the best label once.
