memstat.sh

memstat.sh

Function

The memstat.sh command is used to query the memory usage of all kernel modules to check whether memory leakage occurs, and query the page usage of a specified kernel module.

Format

memstat.sh -a

memstat.sh -c settraceentry [stacklayer]

memstat.sh -c setmemstatswitch [value]

memstat.sh -h

memstat.sh -c setmodulefilter [midName]

memstat.sh -c showmoduletrace

memstat.sh -c showstatinfo

memstat.sh -c showmemstatswitch

memstat.sh -c showtraceentry

memstat.sh -c showmodulefilter

Parameters

None

Modes

Minisystem mode

Usage Guidelines

The "memstat.sh" command is used to query memory usage of all kernel modules to monitor memory leakage. It provides the following functions:

  • Enable or disable the function of collecting memory statistics.
  • Show the switch value of enabling or disabling memory statistics collection.
  • Show buddy and vmalloc memory occupied by all kernel modules.
  • Set the number of call stack layers to be reserved. When setting the number of call stack layers, disable the function of collecting memory statistics.
  • Show the number of call stack layers.
  • Set a filtering module only from kernel modules in the current system.
  • Show the configured filtering module.
  • Show information about pages and call stacks used by the filtering module.

Example

  • Enable or disable the function of collecting memory statistics.

    Storage: minisystem> memstat.sh -c setmemstatswitch 1
    DANGER: You are going to perform a danger command.The execution of this command may consume some system memory.
    Suggestion: Before you perform this operation, make sure that the operation will not affect working of system.
    Have you read danger alert message carefully?(y/n)
    y
    Enter "I have read and understand the consequences associated with performing this operation." to confirm running this command.
    I have read and understand the consequences associated with performing this operation.
    Succeeded in setting the switch value. The switch value is 1.

  • Show help information.

    Storage: minisystem> memstat.sh -h
    memstat.sh [-h] [-a] [-c command] : It's just the memstat modules's command about memory info. Enter memstat.sh -a to obtain more information.
    Storage: minisystem> 
  • Show the operations that can be performed using "memstat.sh".

    Storage: minisystem> memstat.sh -a
    memstat.sh -c setmemstatswitch [value]         : set memstat's switch, [value] is [0|1],0:close,1:open.
    memstat.sh -c settraceentry [stacklayer]       : set the depth of the stack.[stacklayer] is [1-8].
    memstat.sh -c setmodulefilter [midName]        : set module filter, only can set kernel's module.
    memstat.sh -c showmoduletrace                  : show used page information according to module_filter.
    memstat.sh -c showstatinfo                     : show all module's memory info allocated by buddy, vmalloc, slab.
    memstat.sh -c showmemstatswitch                : show memstat's switch.
    memstat.sh -c showtraceentry                   : show memstat's trace entry.
    memstat.sh -c showmodulefilter                 : show filter module.
    Storage: minisystem> 
  • Show the switch value of enabling or disabling memory statistics collection.

    Storage: minisystem> memstat.sh -c showmemstatswitch
    1
    Storage: minisystem>
  • Show buddy and vmalloc memory occupied by all kernel modules.

    Storage: minisystem> memstat.sh -c showstatinfo

    DANGER: You are going to perform a danger command. Memory consumption rises as the number of stack layers increases.
    Suggestion: Before you perform this operation, make sure that the operation will not affect working of system.
    Have you read danger alert message carefully?(y/n)
