# Statistics Variables

Server statistics counters record the number of certain types of events. The LCI allows you to read these statistics to monitor the performance of your Steel-Belted Radius Carrier server.

## Counter Statistics

## Counter Statistics

The statistics counters can be accessed via the LCI by executing the following one line command:

The following sections illustrate the variables displayed for different settings of the stattype parameter.

### stattype: server

### stattype: authentication

### stattype: authentication

### stattype: accounting

### stattype: proxy

## Rate Statistics

## Rate Statistics

Rate statistics are derived from existing counter statistics by taking time into consideration. Overall server rate values calculated for each of these counter statistics consist of the following:

Current rate—The rate measured over the most recent rate interval.

Average rate—The rate measured since the Steel-Belted Radius Carrier server was started or since the last time statistics were reset to zero.

Peak rate—The highest rate observed since the Steel-Belted Radius Carrier server was started or since the last time statistics were reset to zero.

Rate values calculated per NAD client and per Called-Station-ID consist of only current and peak rates.

**Note**

NAD client and Called-Station-ID specific rate statistics are
calculated only if you set the `EnhancedRateStats` parameter in the `radius.ini` file to 1.

Additionally, there is a (read-only) time value used in calculations:

Rate statistics reports the current and peak rate statistics handled by SBR at the time of query.

To read overall server rate statistics from the
LCI, you must set `radiusstatus= statistics` and `stattype= rate`. This results in output
such as the following:

To read rate statistics per NAD client from the LCI, you must
set `radiusstatus=rate_stats_by_nas` and
also input the NAD name for which rate statistics should be displayed.
This results in output such as the following:

To read rate statistics per Called-Station-ID from the LCI,
you must set `radiusstatus=stats_by_calledstationid` and also input the string representing Called-Station-ID for which
rate statistics should be displayed. This results in output such as
the following:
