Viewing Statistics About NIC Operations

You can view statistics for the NIC process and for various NIC components. Table 22 lists the commands you use to view NIC statistics.




Table 22: Commands to Display NIC Statistics
Command
Output Displayed

show nic statistics

All NIC statistics. The output for this command includes the output for the other show nic statistics commands.

show nic statistics agent

NIC statistics for agents.

show nic statistics host

NIC statistics for a NIC host.

show nic statistics process

NIC statistics for the NIC process.

show nic statistics resolver

NIC statistics for resolvers.

show nic statistics slot

All NIC statistics for a specified slot. The output for this command includes the output for the show nic statistics agent, show nic statistics host, show nic statistics process, and show nic statistics resolver commands.

Viewing Statistics for the NIC Process

To view statistics for the NIC process:

user@host> show nic statistics process 
Component Statistics
Component Name process
Heap in use    456194 bytes (87%)
Heap limit     524288 bytes
Threads        42
Up time        747848 seconds since Wed Jan 31 19:35:57 EST 2007

Table 23 describes the output fields for the show nic statistics process command. Output fields are listed in the order in which they appear.




Table 23: show nic statistics process Output Fields
Field Name
Field Description

Component name

Name of component—process indicates the NIC process.

Heap in use

Heap size allocated by the Java Virtual Machine. The percentage indicates the percentage of the heap in use. We recommend that if the percent in use is more than 90% additional heap be allocated for the NIC.

Heap limit

Size of Java heap configured for the NIC.

Threads

Number of threads in use.

Up time

Length of time NIC has been running on the system. Includes the date and time at which NIC was last started.

Viewing Statistics for a NIC Host

To view statistics for a NIC host:

user@host> show nic statistics host 
Component Statistics
Component Name                 /hosts
Number of Components Restart   0
Number of No Match Resolutions 0
Number of Resolution Errors    0
Number of Resolutions          0

Table 24 describes the output fields for the show nic statistics host command. Output fields are listed in the order in which they appear.




Table 24: show nic statistics host Output Fields

Name of component—/hosts indicates NIC host. A specific host has the format /hosts/hostname.

Number of Components Restart

Number of NIC resolvers and agents that have restarted in the host.

Number of No Match Resolutions

Number of resolution requests that did not return data.

Number of Resolution Errors

Number of errors encountered when processing resolutions requests.

Number of Resolutions

Number of successful data resolutions; for example, the SAE reference for a specified IP address, the login name for a specified IP address, or the SAE reference for a specified login name.

Viewing Statistics for NIC Resolvers

To interpret the statistics for NIC resolvers, make sure that you have a good understanding of the NIC resolutions process.

See SRC-PE Network Guide, Chapter 17, NIC Resolution Process.

To view statistics for NIC resolvers:

user@host> show nic statistics resolver 
Component Statistics
Component Name           /realms/login/A1

Resolver Size            0

Component Statistics
Component Name           /realms/login/B1
Number of Data Sources   1
Resolver Size            0

Component Statistics
Component Name           /realms/login/C1
Number of Data Sources   1
Resolver Size            2140

Component Statistics
Component Name           /realms/login/D1
Number of Data Sources   2
Resolver Size            0

Table 25 describes the output fields for the show nic statistics resolver command. Output fields are listed in the order in which they appear.




Table 25: show nic statistics resolver Output Fields
Field Name
Field Description

Component name

Name of a resolver. Resolver names have the format /realms/realm-name/resolver name.

Number of Data Sources

The number of sources from which the resolver obtains data. A data source can be an agent or another resolver.

Resolver Size

The number of keys (or number of mappings) required to perform this resolution.

Viewing Statistics for NIC Agents

To interpret the statistics for NIC agents, make sure that you have a good understanding of the NIC agents.

See SRC-PE Network Guide, Chapter 9, Locating Subscriber Information with the NIC.
