| # Introduction | ||
|
|
||
| Allocates a specific amount of memory. | ||
|
|
||
| # Usage | ||
|
|
||
| Note that this can cause systems to trip the Linux Kernel OOM killer without enough physical or swap Memory. | ||
| The operating system may swap out the allocated memory. This attack doesn't take swap memory into account. | ||
|
|
||
| In contrast to the [Stress Memory](/action/com.steadybit.extension_container.stress_mem) action, this actions tries to reduce the CPU usage as much as possible. | ||
|
|
||
| When using the attack to meet a specific memory usage, it may allocate or free memory to reach the desired memory usage. | ||
|
|
||
| > If you specify a usage that exceeds the total memory (e.g. > 100%) it fills up the memory as much as possible until the process is oomkilled, as it's impossible to reach usages higher than 100%. | ||
| # Use Cases | ||
|
|
||
| * Test the system's ability to handle memory spikes. | ||
| * Observe the system's behavior when it runs out of memory. | ||
| * Observe the system's behavior when it runs low on memory for file buffers. | ||
|
|
||
| # Parameters | ||
|
|
||
| | Parameter | Description | Default | | ||
| |------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------------| | ||
| | Duration | How long should memory be wasted? | 30s | | ||
| | Mode | **Fill and meet specified usage:** Fill up the memory until the desired usage is met. Memory allocation will be adjusted constantly to meet the target.<br/> **Fill the specified amount**: Allocate and hold the specified amount of Memory. | Fill and meet specified usage | | ||
| | Size | **Percentage of total memory** or **Megabytes**: | % of total memory | | ||
| | Fail on OOM Kill | Should it be treated as a failure when the attacked container was oomkilled? | False | |
