Configuring Memory Usage
Warning Threshold
System memory is an important resource in system operation. When the available
system memory is insufficient, many important services won't be able to run normally.
The continual drop in system memory may indicate certain faults. Therefore, the
administrator generally expects that the device can give an alarm when system
memory has dropped to a certain extent. The LCD module can give an alarm when the
memory usage is excessively high.
By default, when system memory usage reaches 80%, the warning message will be
operation, transiently high memory usage may be
e frequently (for example, mem ming calculation is running by this
time), which shall be considered normal. Therefore, it is not suggested to set memory
