Summary
The DRX logs output the same logs to the following two paths.
- Standard output
- Log file
When operating in service mode, the standard output is not used.
The file output is distributed to the main and resource logs.
| File | Path | Content |
|---|---|---|
| main log file | {DRX installed path}/logs/main.log | DRX operation. Exclude actions by resources |
| resource-specific log file | {DRX installed path}/logs/{resource_name}/{resource_name}.log | Behavior of resources |
When each file reaches the set size, the file is archived and a new one is created.
The file being archived is appended with the date and time at that point in time. (ex: main_2018-11-22_1432.log)
Log View
The following types of commands are provided to output the active DRX log in real time.
drx-ctl log {options} [resource or all]
Supported options:
| Option | Shortcut | Description |
|---|---|---|
| --include-main | -m | Print the main log. If this option is not specified, only resource-specific logs are output. |
| --lines {num} | -n {num} | Output the last num lines. |
When you execute this command, you can continuously output the update of the log file and terminate it with Ctrl-C.
Configuration
The log-related items that can be set in the configuration file (drx.conf) are as follows.
| Item | Value | Format | Description |
|---|---|---|---|
| loglevel-stdout | Log level | trace, debug, info, warning, error, critical, off | Specifies the level of the standard output log. |
| loglevel-file | Log level | trace, debug, info, warning, error, critical, off | Specifies the level of the log output to the file. |
| logfile-max-size | File size | Bytes (ex: 10MB) | When the log file reaches the specified capacity, the current log file is archived and a new one is created. |
| logfile-max-count | File count | Number | Maximum number of current and archived log files. |
The log level can be changed in real time via drx-ctl.
drx-ctl set console-loglevel [level]
drx-ctl set file-loglevel [level]
However, the standard output level is ignored when running in service mode.

Resource-specific logger
Resource-specific loggers are assigned the name of the resource as the name of the logger.
Each resource consists of two channels, so it has the following tags.
{connection direction}{channel type}
In addition, since each channel is composed of two proxy connections, the detailed tag of each connection is as follows.
{connection direction}{channel type}:{proxy location}
Details by tag
Each item
| Item | Value | Description |
|---|---|---|
| Connection direction | a | Acceptor. (Local DRBD → Local DRX ← Remote DRX) |
| c | Connector. (Local DRBD ← Local DRX → Remote DRX) | |
| Channel type | - | Undefined. It is determined after connecting with DRBD. |
| m | Meta channel | |
| d | Data channel | |
| Proxy location | i | Inside. Connection with local DRBD. |
| o | Outside. Connection with remote DRX. |
Assuming that the resource name is 'r0', a logger with the following configuration exists.
| Resource | Channel type | Proxy location | Tag |
|---|---|---|---|
| r0 | - | - | r0 |
| Acceptor | - | r0:a | |
| Inside | r0:a-:i | ||
| Outside | r0:a-:o | ||
| Connector | - | r0:c | |
