Admin Server logs use the Common Logfile Format, a broadly supported format that provides information red hat linux log files about the server. Admin Server generates two kinds of logs: Access logs.

logs show requests to and responses from the Admin Server. By default, the file is located at /var/log/dirsrv/admin-servaccess. Error logs. linux log files explained Error logs show messages for errors which the server has encountered since the log file was created. It also contains informational messages about the server, such as when the server was started and who what are log files in linux tried unsuccessfully to log on to the server. By default, the file is located at /var/log/dirsrv/admin-serverror. The logs can be viewed through Admin Server Console or by opening the log file. 2.4.1. Viewing the Logs through the Console Open the Admin Server management window. Click the Configuration tab. Expand the Logs directory, and click the log file name, either Accesses or Error. 2.4.2.

The access log, by default, is at /var/log/dirsrv/admin-servaccess. To view the access log, open it in an editor such as vi. Access logs show connections to the Admin Server based on the IP address of the client, the username, and the method that the request was sent. Each line has the following format: ip_address - bind_DN [timestamp -0500] "GET|POST cgi" HTTP_response bytes Example logs are shown in Example 2.1, “Example Access Logs”. Example 2.1.

To view the error log, open it in an editor such as vi. Error logs record any problem response from the Admin Server. Like the access log, error logs also records entries based the client's IP address, along with the type of error message, and the message text: [timestamp] [severity] [client ip_address error_message The severity message indicates whether the error is critical enough for administrator intervention. [warning], [error], and [critical] require immediate administrator action. Any other severity means the error is informational or for debuggin

Additional Resources Log files are files that contain messages about the system, including the kernel, services, and applications running on it. There are different log files for different information. For example, there is a default system log file, a log file just for security messages, and a log file for cron tasks. Log files can be very useful when trying to troubleshoot a problem with the system suc
Event LoggingIt is possible to edit the /etc/syslog.conf file to enable the cluster to log events to a file that is https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/2.1/html/Cluster_Manager_Installation_and_Administration/s1-software-syslog.html different from the /var/log/messages log file. Logging cluster messages http://unix.stackexchange.com/questions/38978/where-are-apache-file-access-logs-stored to a separate file will help to diagnose problems more clearly.
The cluster systems use the syslogd daemon to log cluster-related events to a file, as specified in the /etc/syslog.conf file. The log file facilitates diagnosis of problems in the log file cluster. It is recommended to set up event logging so that the syslogd daemon logs cluster messages only from the system on which it is running. Therefore, you need to examine the log files on both cluster systems to get a comprehensive view of the cluster.The syslogd daemon logs messages from linux log files the following cluster daemons:cluquorumd -- Quorum daemonclusvcmgrd -- Service manager daemonclupowerd -- Power daemoncluhbd -- Heartbeat daemonclumibd -- Administrative system monitoring daemonThe importance of an event determines the severity level of the log entry. Important events should be investigated before they affect cluster availability. The cluster can log messages with the following severity levels, listed in order of severity level:emerg -- The cluster system is unusable.alert -- Action must be taken immediately to address the problem.crit -- A critical condition has occurred.err -- An error has occurred.warning -- A significant event that may require attention has occurred.notice -- An event that does not affect system operation has occurred.info -- An normal cluster operation has occurred.dhere for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this site About Us Learn more about Stack Overflow the company Business Learn more about hiring developers or posting ads with us Unix & Linux Questions Tags Users Badges Unanswered Ask Question _ Unix & Linux Stack Exchange is a question and answer site for users of Linux, FreeBSD and other Un*x-like operating systems.

Logs are typically under /var/log, but some systems have them elsewhere. –Gilles May 19 '12 at 12:51 add a comment| 3 Answers 3 active oldest votes up vote 94 down vote accepted Ultimately, this depends on your Apache configuration. Look for CustomLog directives in your Apache configuration, see the manual for examples. A typical location for all log files is /var/log and subdirectories. Try /var/log/apache/access.log or /var/log/apache2/access.log. If the logs aren't there, try running locate access.log. share|improve this answer answered May 19 '12 at 12:54 Gilles 374k696801129 +1 for CustomLog –Radu Sep 30 at 14:05 add a comment| up vote 21 down vote If you can't find the log with Gilles's answer, there are a couple more things you can try. Look in /var/log/httpd. Run sudo locate access.log as well as sudo locate access_log. The logs on my system were not visible except to root, and the file was called access_log instead of access.log. share|improve this answer answered Jan 27 '15 at 19:28 Don Kirkby 31124 3 +1 for /var/log/httpd - led me right to it on our CentOS installation –Chuck Wilbur Oct 2 '15 at 19:27 add a comment| up vote 5 down vote Apache server records all incoming requests and all requests processed to a log file.
