Description

Exposing the Ranger REST API is used to fetch the health check status of Ranger Admin

 

RangerAdmin Health Check JSON Response look like (In the current implementation)
{
"status": "UP",
"components": {
"db": {
"status": "UP",
"details":

{ "database": "Oracle 21.3c", "validationQuery": "SELECT banner from v$version where rownum<2" }

}
}
}
In the future we can extend this health check API for other components like AuditHandler (Elastic search, Kafka,HDFS, Solr),KMS ,etc
Another Example :
{
"status": "UP",
"components": {
"db": {
"status": "UP",
"details":

{ "database": "Oracle 21.3c", "validationQuery": "SELECT banner from v$version where rownum<2" }

},
"auditProvider": {
"status": "UP",
"details":

{ "provider": "Elastic Search", "providerHealthCheckEndpoint": "http://localhost:9200/_cluster/health?pretty" }

}
}
}
