Juniper SYSTEM BASICS - CONFIGURATION GUIDE V 11.1.X User Manual

■ slot—Slot in which the module resides
■ type—Type of module
■ heap (%)—Percentage of the RAM that is currently in use by software running
on the module
■ cpu (%)—Percentage of the module CPU capacity currently used; this field
appears only when the detail keyword is omitted
■ bw exceed—Status of bandwidth oversubscription for this slot; this field
appears only when bandwidth oversubscription is configured
■ Y indicates that this slot is in an oversubscribed slot group
■ --- indicates that no module is installed or slot has no bandwidth
oversubscription
■ The following additional fields appear when the detail keyword is used:
■ last available cpu (%)—Average CPU utilization percentage for each
installed module during the last 5-second interval for which data was
available. If the current CPU utilization data for a module is not available
at any point, the last available cpu (%) field displays the last available
5-second CPU utilization percentage, which is the same value that
appears in the cpu (%) field when the detail keyword is omitted. If the
current 5-second CPU utilization data is available, the last available
cpu (%) field and the 5 sec cpu (%) field display the same value.
■ 5 sec cpu (%)—Average CPU utilization percentage for each installed
module during the most recent 5-second interval
■ 1 min cpu (%)—Average CPU utilization percentage for each installed
module during the most recent 1-minute interval
■ 5 min cpu (%)—Average CPU utilization percentage for each installed
module during the most recent 5-minute interval
■ Depending on the output of the show utilization command when you use
the detail keyword, some or all of the following symbols and explanatory
notes might appear:
■ --- indicates an empty slot on ERX7xx models, ERX14xx models, or the
ERX310 router. For the E120 and E320 routers, this symbol indicates
either an empty slot, or a fabric slice that resides on an SRP module or
on a switch fabric module (SFM).
■ ??? indicates that the current CPU utilization data is unavailable for the
specified interval. Data might be unavailable for one or more of the
following reasons:
■ A slot is in an inactive state.
■ A line module is very busy (that is, using 100 percent of its CPU
capacity) and is unable to send its CPU utilization data to the SRP
module.
■ A line module is experiencing communication problems that prevent
it from sending its CPU utilization data to the SRP module.
