The mock input plugin generates random data based on a selection of different
algorithms. For example, it can produce random data between a set of values,
fake stock data, sine waves, and step-wise values.
Additionally, users can set the measurement name and tags used to whatever is
required to mock their situation.
Global configuration options
In addition to the plugin-specific configuration settings, plugins support
additional global and plugin configuration settings. These settings are used to
modify metrics, tags, and field or create aliases and configure ordering, etc.
See the CONFIGURATION.md for more details.
Configuration
# Generate metrics for test and demonstration purposes
[[inputs.mock]]
## Set the metric name to use for reporting
metric_name = "mock"
## Optional string key-value pairs of tags to add to all metrics
# [inputs.mock.tags]
# "key" = "value"
## One or more mock data fields *must* be defined.
##
## [[inputs.mock.constant]]
## name = "constant"
## value = value_of_any_type
## [[inputs.mock.random]]
## name = "rand"
## min = 1.0
## max = 6.0
## [[inputs.mock.sine_wave]]
## name = "wave"
## amplitude = 1.0
## period = 0.5
## [[inputs.mock.step]]
## name = "plus_one"
## start = 0.0
## step = 1.0
## [[inputs.mock.stock]]
## name = "abc"
## price = 50.00
## volatility = 0.2
The mock plugin only requires that:
- Metric name is set
- One of the data field algorithms is defined
Available Algorithms
The available algorithms for generating mock data include:
- Constant - generate a field with the given value of type string, float, int
or bool
- Random Float - generate a random float, inclusive of min and max
- Sine Wave - produce a sine wave with a certain amplitude and period
- Step - always add the step value, negative values accepted
- Stock - generate fake, stock-like price values based on a volatility variable
Metrics
Metrics are entirely based on the user's own configuration and settings.
