For system administrators, tasked to make sure the system is running without major issues, logging 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 AIX not only offers the errpt but also other error reporting logs. Using the alog command one can list and pick a log to

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 upgrade completed - no errors- test" Working With errpt The first thing AIX admins should do is get event notifications via email. Those errors/warnings will be emailed as well as posted to the errpt log. First, create an email alias containing all system admins’ addresses in the /etc/

These messages are written in order to identify the failing component, associated reason for the https://www.ibm.com/developerworks/aix/library/au-aix-read-detail-data-error-log/ 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 applications, you can use t

The label of each new entry is checked against the contents of the Error Record Template Repository, and if a match is found, additional information about the system environment or hardware status is added. A memory buffer is set by the errdemon process, and newly arrived entries are put into the buffer before they are written to the log to minimize the possibility of a lost entry. The errlog file is a circular log, storing as many entries as can fit within its defined size, the default is /var/adm/ras/errlog and it is in binary format The name and size of the error log file and the size of the memory buffer may be viewed with the errdemon command: # /usr/lib/errdemon -l Log File /var/adm/ras/errlog Log Size 1048576 bytes Memory Buffer Size 32768 bytes ------------------------------ /usr/lib/errd
