Systems Magazine forums. 11 February 2014 Also available inRussian Table of contents Introduction Logging an entry Reading the logged entries Basics to reading error-log entries Example Resources Comments IntroductionError-logging is a facility using which an operating system module or an user application can log any detected errors. These messages are written in order to identify the failing component, associated reason aix system error log 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 is intended. At the same time, care should be taken so that there in no sudden flood of entries that can negatively impact the search of error entries.Logging an entryUsers can log an error entry using the following two mechanisms: Using a function: From user applic

For system administrators, tasked to make sure the system is running without major issues, logging https://www.ibm.com/developerworks/aix/library/au-aix-read-detail-data-error-log/ provides 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 http://www.ibmsystemsmag.com/aix/administrator/systemsmanagement/error_logs/ 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:
log. REFERENCE Please contact the Data http://www.unixguide.net/ibm/faq/faq1.115.shtml Center Supervisor to clarify any process within this procedure and for any concern beyond its scope. OVERVIEW and PROCEDURE The task that is described in this procedure is performed in the AIX terminal window. If the error log terminal window is not open at this time, you may do so by using the instructions in Hardware Management Console Overview. After the terminal window is open, simply type errpt |pg (|pg permits you to display one page at a time) The columns that you aix error log need to review are: TIMESTAMP (Column #2) Provides a shortcut version of the date and time. Example:0827041503 0827 = August 27th 0415 = 4:15 AM OR 04:15 hours 03 = the year, 2003 T (Column #3) Displays the type code for the error: I = Informational P = Permanent T = Temporary Warning: If a type code of P (Permanent) appears, contact the appropriate AIX Support team member as indicated in the on-call list. C (Column #4) Displays a descriptor of the environment in which the error has occurred. The codes are: H = Hardware S = Software O = Operating Environment To review the instructions for other AIX commands that you can use in the terminal window, click the Related Topics button below.
