基于配置文件生成虚拟日志
log-generator的Python项目详细描述
log_generator根据配置文件生成虚拟日志。
usage: log-generator [-h] [--level LEVEL] [--truncate] /path/to/config
Generate log events
positional arguments:
/path/to/config Path to configuration directory
optional arguments:
-h, --help show this help message and exit
--level LEVEL, -l LEVEL
Logging level
--truncate, -t Truncate the log files on start
配置文件
日志生成器使用一组配置文件来定义如何生成日志。 您可以在log_generator/schema.yaml中看到配置文件的架构。 有6个必需属性：name，file，format，frequency，amount，和fields：
| name: | Name of the logs being generated (for logging purposes only) |
|---|---|
| file: | The path to the file where to write the logs to |
| frequency: | Time frame of how frequently to output logs |
| amount: | Number of logs to create per tick |
| enabled: | (optional) Boolean as to whether the configuration file should be used (default True) |
| offset: | (optional) Time frame of the offset, from now, the timestamps should be |
| jitter: | (optional) Time frame of the jitter the timestamps should be. |
| format: | The format of the log |
| fields: | A dictionary of fields to be substituted into the log format |
fields的每个属性都应该是以下类型之一：
| type: | One of ^{tt10}$, ^{tt11}$, ^{tt12}$, ^{tt13}$, ^{tt14}$, ^{tt15}$ |
|---|---|
| repeat: | (optional) Number of times to repeat the current value before generating (default 1) |
| change: | (optional) Float probability [0..1] that the current value will change (default 1) |
| value: | (optional) The initial value for the field |
- 枚举（enum）
具有被选择的均匀分布的值的列表。
values: List of possible options - 时间戳（timestamp） 时间戳。
- 整数（integer）
随机整数值。
min: Minimum value of the integer max: Maximum value of the integer - 浮动（float）
随机浮点值。
min: Minimum value of the float max: Maximum value of the float - 机会（chance）
定义被选中概率的一组选项和相关权重
choices: A list of objects with two properties: ^{tt21}$ and ^{tt22}$ choices.*.option: The value of the option choices.*.weight: The probability of being selected - IP地址（ip）
- 随机生成的IP地址。
| format: | The format that the timestamp should have |
|---|
示例
apache 2.4访问：
name: Apache General Access
file: /var/log/httpd/apache_access
format: "{log_ip} - - [{log_time} +0000] \"{log_method} {log_path} HTTP/1.1\" {log_status} {log_bytes}"
frequency:
seconds: 5
offset:
seconds: 0
jitter:
seconds: 5
amount: 50
fields:
log_ip:
type: ip
log_time:
type: timestamp
format: "%d/%b/%Y:%H:%M:%S"
log_method:

log_path:
type: enum
values:
- /auth
- /alerts

log_status:
type: enum
values: [200, 201, 204, 300, 301, 400, 401, 403, 404, 500, 503]
log_bytes:
type: integer
min: 2000
max: 5000
自定义日志：
name: Simulated Field Change
file: /var/log/server/status
format: "{log_time} server status: {log_colour}"
frequency:
seconds: 11
offset:
seconds: 0
amount: 1
fields:
log_time:
type: timestamp
format: "%Y-%m-%dT%H:%M:%SZ"
log_colour:
type: chance
repeat: 11
change: 0.25
value: green
choices:
- option: red
weight: 0.2
- option: yellow
weight: 0.2
- option: green
weight: 0.6
