Plugin Monitoring

Table of contents

Introduction

By a stats endpoint, you are able to collect metrics for the plugin within the interval. Note that only node level statistics collecting is implemented for now. In other words, you only get the metrics for the node you're accessing. Cluster level statistics have yet to be implemented.

Node Stats

Description

The meaning of fields in the response is as follows:

Field name Description
request_total Total count of request
request_count Total count of request within the interval
default_cursor_request_total Total count of simple cursor request
default_cursor_request_count Total count of simple cursor request within the interval
failed_request_count_syserr Count of failed request due to system error within the interval
failed_request_count_cuserr Count of failed request due to bad request within the interval
failed_request_count_cb Indicate if plugin is being circuit broken within the interval

Example

SQL query:

>> curl -H 'Content-Type: application/json' -X GET localhost:9200/_plugins/_sql/stats

Result set:

{
  "failed_request_count_cb" : 0,
  "default_cursor_request_count" : 10,
  "default_cursor_request_total" : 3,
  "failed_request_count_cuserr" : 0,
  "circuit_breaker" : 0,
  "request_total" : 70,
  "request_count" : 0,
  "failed_request_count_syserr" : 0
}
