Configuring System Logging Counts
This document describes the System Logging (error logging) count enhancement feature in Cisco IOS Release 12.2(8)T. It includes the following sections:
Feature Overview
The Cisco IOS logging facility allows you to save error messages locally or to a remote host. When these error messages exceed the capacity of the local buffer dedicated to storing them, the oldest messages are removed. To provide you with more information about messages that have occurred and may have been removed from the local buffer, an error log counter tabulates the occurrences of each error message, and time-stamps the most recent occurrence.
These messages are further sorted by message facility. Messages from each message facility are grouped together and totaled in the count. If a message is rate-limited, the count is incremented based on the actual messages that have occurred.
The service timestamps command configuration determines the format of the "Last Time" column in the show logging command output. Use the service timestamps command to configure the time-stamp format in the "Last Time" column.
Benefits
- Provides detailed information regarding system messages, including the most recent time the message occurred.
- Alerts you to a potential problem with the system if you see the same error message occurring repeatedly.
