Queries History

Queries API allows you to retrieve SQL queries executed on your cluster.

Retrieve queries count

GET /api/monitor/get/query/count/:start/:end

This endpoint retrieve the number of queries starting between :start and :end timestamps.

Example:

CODE

curl http://myindeximacluster:8082/api/monitor/get/query/count/1667075793000/1667075937000 \
  -H "Authorization: $ACCESS_TOKEN" \
  -H "Monitor-Target-Host: indexima-core-1" \
  -H "Monitor-Target-Port: 9999" \
  --compressed -s | jq

Retrieve queries listing

GET /api/monitor/get/query/desc/:start/:end/:limit

GET /api/monitor/get/query/asc/:start/:end/:limit

This endpoint retrieve all queries starting between :start and :end timestamps.
Queries will be ordered ascending with /get/query/asc or descending with /get/query/desc .
The timestamps for :start and :end are unix timestamps in milliseconds.
The parameter :limit is the maximum number of queries to retrieve.
The sql field, containing the sql statement, is truncated to 100 characters in this endpoint. Use /api/query/sql endpoint to retrieve the complete statement.

Example:

CODE

curl http://myindeximacluster:8082/api/monitor/get/query/desc/1667075793000/1667075937000/2 \
  -H "Authorization: $ACCESS_TOKEN" \
  -H "Monitor-Target-Host: indexima-core-1" \
  -H "Monitor-Target-Port: 9999" \
