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.
