healthcheck_config

The healthcheck_config section configures thresholds and timeout settings used by the YDB health check service. These parameters help configure detection of potential issues, such as excessive restarts or time drift between dynamic nodes.

Syntax

healthcheck_config:
  thresholds:
    node_restarts_yellow: 10
    node_restarts_orange: 30
    nodes_time_difference_yellow: 5000
    nodes_time_difference_orange: 25000
    tablets_restarts_orange: 30
  timeout: 20000

Parameters

Parameter	Default	Description
`thresholds.node_restarts_yellow`	`10`	Number of node restarts to trigger a `YELLOW` warning
`thresholds.node_restarts_orange`	`30`	Number of node restarts to trigger an `ORANGE` alert
`thresholds.nodes_time_difference_yellow`	`5000`	Max allowed time difference (in us) between dynamic nodes for `YELLOW` issue
`thresholds.nodes_time_difference_orange`	`25000`	Max allowed time difference (in us) between dynamic nodes for `ORANGE` issue
`thresholds.tablets_restarts_orange`	`30`	Number of tablet restarts to trigger an `ORANGE` alert
`timeout`	`20000`	Maximum health check response time (in ms)
