Intro

Admin tool allows us to dynamically change settings of the running node without a restart. It can be used to change log level, and turn on profiler etc.

Usage

List all commands

curl localhost:9002/admin/run_command -H 'Content-Type: application/json' -d '{"commandName": "list-commands"}'

To change log level

Flow, and other zerolog-based libraries:

curl localhost:9002/admin/run_command -H 'Content-Type: application/json' -d '{"commandName": "set-log-level", "data": "debug"}'

libp2p, badger, and other golog-based libraries:

curl localhost:9002/admin/run_command -H 'Content-Type: application/json' -d '{"commandName": "set-golog-level", "data": "debug"}'

To turn on profiler

curl localhost:9002/admin/run_command -H 'Content-Type: application/json' -d '{"commandName": "set-profiler-enabled", "data": true}'

To get the latest finalized block

curl localhost:9002/admin/run_command -H 'Content-Type: application/json' -d '{"commandName": "read-blocks", "data": { "block": "final" }}'

To get the latest sealed block

curl localhost:9002/admin/run_command -H 'Content-Type: application/json' -d '{"commandName": "read-blocks", "data": { "block": "sealed" }}'

To get block by height

curl localhost:9002/admin/run_command -H 'Content-Type: application/json' -d '{"commandName": "read-blocks", "data": { "block": 24998900 }}'

To get identity by peer id

curl localhost:9002/admin/run_command -H 'Content-Type: application/json' -d '{"commandName": "get-latest-identity", "data": { "peer_id": "QmNqszdfyEZmMCXcnoUdBDWboFvVLF5reyKPuiqFQT77Vw" }}'

To get transactions for ranges (only available to staked access and execution nodes)

curl localhost:9002/admin/run_command -H 'Content-Type: application/json' -d '{"commandName": "get-transactions", "data": { "start-height": 340, "end-height": 343 }}'

To get execution data for a block by execution_data_id (only available execution nodes and access nodes with execution sync enabled)

curl localhost:9002/admin/run_command -H 'Content-Type: application/json' -d '{"commandName": "read-execution-data", "data": { "execution_data_id": "2fff2b05e7226c58e3c14b3549ab44a354754761c5baa721ea0d1ea26d069dc4" }}'

To get a list of all updatable configs

curl localhost:9002/admin/run_command -H 'Content-Type: application/json' -d '{"commandName": "list-configs"}'

To get a config value

curl localhost:9002/admin/run_command -H 'Content-Type: application/json' -d '{"commandName": "get-config", "data": "consensus-required-approvals-for-sealing"}'

To set a config value

Example: require 1 approval for consensus sealing

curl localhost:9002/admin/run_command -H 'Content-Type: application/json' -d '{"commandName": "set-config", "data": {"consensus-required-approvals-for-sealing": 1}}'

Example: set block rate delay to 750ms

curl localhost:9002/admin/run_command -H 'Content-Type: application/json' -d '{"commandName": "set-config", "data": {"hotstuff-block-rate-delay": "750ms"}}'

Example: enable the auto-profiler

curl localhost:9002/admin/run_command -H 'Content-Type: application/json' -d '{"commandName": "set-config", "data": {"profiler-enabled": true}}'

Example: manually trigger the auto-profiler for 1 minute

curl localhost:9002/admin/run_command -H 'Content-Type: application/json' -d '{"commandName": "set-config", "data": {"profiler-trigger": "1m"}}'

Set a stop height

curl localhost:9002/admin/run_command -H 'Content-Type: application/json' -d '{"commandName": "stop-at-height", "data": { "height": 1111, "crash": false }}'

Types

type CommandHandler

type CommandHandler func(ctx context.Context, request *CommandRequest) (interface{}, error)

type CommandRequest

type CommandRequest struct {
	// Data is the payload of the request, generated by the request initiator.
	// This is populated by the admin command framework and is available to both
	// Validator and Handler functions.
	Data interface{}
	// ValidatorData may be optionally set by the Validator function, and will
	// then be available for use in the Handler function.
	ValidatorData interface{}
}

CommandRequest is the structure of an admin command request.

	// contains filtered or unexported fields
}
