Release Information

Command introduced before Junos OS Release 7.4.

Command introduced in Junos OS Release 9.0 for EX Series switches.

Description

Display memory utilization for routing protocol tasks on the Routing Engine.

Note

The show task memory command does not display all the memory used by the routing protocol process. This value does not account for the memory used for the TEXT and STACK segments, or the memory used by the routing protocol process’s internal memory manager.

Options

noneDisplay standard information about memory utilization for routing protocol tasks on the Routing Engine on all logical systems.
brief | detail | history | summary(Optional) Display the specified level of output. Use the history option to display a history of memory utilization information.
logical-system (all | logical-system-name)(Optional) Perform this operation on all logical systems or on a particular logical system.

Field Name

Field Description

Level of Output

Memory Currently In Use

Memory currently in use. Dynamically allocated memory plus the DATA segment memory in kilobytes.

All levels

Memory Maximum Ever Used

Maximum memory ever used.

none specified, brief, history

Memory Available

Memory currently available.

Note: The maximum currently available memory is displayed incorrectly. On 32-bit Junos OS, the actual available memory is 2,097,152 kilobytes (2147483648 / 1048) but instead it is displayed as 2,147,484 kilobytes (2147483648 / 1000). On 64-bit Junos OS, the actual available memory is 3,145,728 kilobytes (3221225472 / 1048) but instead it is displayed as 3221225 kilobytes (3221225472 / 1000).

Overall Memory Report

Memory utilization by memory size:

  • Size—Block size, in bytes.

  • TXPT indicates transient memory, X indicates exclusive memory, and P indicates full page.

  • Allocs—Number of blocks allocated for named objects.

  • Mallocs—Number of blocks allocated for anonymous objects.

  • Alloc Bytes—Number of blocks allocated times block size.

  • MaxAllocs—Maximum value ofAllocs.

  • MaxBytes—Maximum value of Alloc Bytes.

  • FreeBytes—Total number of bytes unused on memory pages for this block size.
