Logging Reference
Chia blockchain nodes consist of several components that each handle different aspects of farming, harvesting, the wallet and general management of a node. Each component creates entries in a single log file debug.log.
Log file Location:
| OS | Location |
|---|---|
| Linux | ~/.chia/mainnet/log/debug.log |
| Windows | %systemdrive% %homepath% \.chia\mainnet\debug.log (C:\Users\<username>\.chia…) |
| MacOS | /Users/<username>/.chia/mainnet/log/debug.log |
Log File Management:
By default, Chia allows debug.log to grow to 20MB, and then rotates the file by closing debug.log, renaming it to debug.log.1, and renames any existing older log files to debug.log.x, to a maximum of 7 old log files. If a log rotation is required and all 7 old log files exist, the oldest log file is overwritten with the next earliest file; resulting in a maximum of 160MB of the most recent messages being stored.
Log Detail Level:
Chia is shipped with the debug.log only containing messages at the WARN or ERROR level. Many of the messages needed to fully monitor a node are only visible at the INFO level. Changes to the logging level can be done in the config.yaml file in the mainnet/config folder.
Change the Log Level Output:
You are looking for the first reference to logging in the file that looks like this:
farmer:
logging: &id001
log_filename: log/debug.log
log_level: WARN
log_stdout: false
Change the log_level to INFO, save the file, and restart the node.
Node Components:
| Component | Function |
|---|---|
| farmer_server | Signage stuff about signs and things |
| harvester_server | Gathers and shares plot information |
| timelord_server | Manages Verifiable Delay Functions for the node |
| wallet_server | Controls wallet functions |
| full_node_server | This component manages the node |
Log Message Format:
| Field | 内容 |

Log Messages Confirming Node Health:
09:55:43.847 harvester src.harvester.harvester : INFO 1 plots were eligible for farming 2d8b1c58a0... Found 0 proofs. Time: 0.13772 s. Total 100 plots
09:55:52.737 harvester src.harvester.harvester : INFO 3 plots were eligible for farming 2d8b1c58a0... Found 0 proofs. Time: 0.43679 s. Total 100 plots
09:56:01.646 harvester src.harvester.harvester : INFO 2 plots were eligible for farming 2d8b1c58a0... Found 0 proofs. Time: 0.14055 s. Total 100 plots
x plots were eligible for farming – This message from the harvester shows how the node responds to challenges. The x value shows how many plots passed the initial filter, more on filters here.
- The block prefix is shown, and the
Found y proofs.Theyvalue shows how many plots were accepted as proofs, and usually the value is zero. Most of the time if there is a proof you win, but not always as described in the FAQ page. - Next is
Time: x.xxx swhich shows how long the node took to respond to the challenge. A recommended response time is less than 5 seconds. If this value is greater than 3 seconds a warning will be displayed in the GUI. - Finally
Total x plotsshows the number of plots recognized by the node. If this doesn't look right check your plots are valid.
Another log message you will see is Updated Wallet peak to height x, weight y - This message is from the wallet_blockchain component. Value x is the current height of the blockchain and should match the Height shown in the chia show -s command. This indicates that the node wallet is fully synced with the network. If that is not the case check here for a common solution.
