Aix Error Log File
AIX provides comprehensive logging of events—some are errors requiring attention and others are just notifications. For system administrators, tasked to make sure the system is running without major issues, logging provides aix log io error alerts or apprises them of events as they happen. AIX offers different logs depending on the action and when it occurred. These logs hold information on the boot-up process, console, hardware and system software events. It’s up to the system admin to take action on these events, because once AIX has published the log, its job is done. Logs, Logs, Logs AIX crontab log aix not only offers the errpt but also other error reporting logs. Using the alog command one can list and pick a log to view: # alog -L boot bosinst nim console cfg mdmplog lvmt lvmcfg dumpsymp When issues arise during the boot-up process, for example, and you’re not at the console, you can review the start-up process messages, particularly the boot and console messages. To list the available logs: alog -o -t For example, to view the console log: alog -o -t console Logging Your Own Entries The standard errpt list hardware or software events in AIX that have occurred. However, you might want a message generated and inserted into errpt after some user interaction, for instance, if a system admin has made a change. This allows the change notification to be visible via errpt. Like the logger command that writes to the system log (messages file), errlogger will write an operator notification entry to the error log. For example, having completed an AIX upgrade, you could post that to the error log, so other users could view it, like so: errlogger "AIX upgra

These messages are written in order to identify the failing component, associated reason for the same, and any additional information. This set of information is aimed to help understand the reason for the failure of a component or any unexpected behavior. However, it is important to note that you cannot solely rely on this because this is a first failure data capture mechanism only. For example, if a user realizes that a connection to a disk has failed with an error-log entry, then it indicates the reason why writes might be failing for an application. An error-log entry of low paging space is very common and this entry indicates the user to increase paging space, as otherwise, the system might behave unexpectedly. Because error logging is a serviceability mechanism, you should place them wisely with the required information so that it can clearly indicate what
