In this article we’ll guide on you how to check your server’s log files in windows and linux system.<\/p>\n<\/div>\n<\/div>\n

Microsoft Windows Server<\/h3>\n
\n
\n

We recommend that you use the Event Viewer to evaluate the log files.\u00a0To open the Event Viewer, press the key combination\u00a0Win\u00a0<\/strong>+\u00a0R<\/strong>. Then enter the command\u00a0eventvwr<\/strong><\/span>\u00a0and press\u00a0Enter<\/strong>.<\/p>\n

In the navigation bar on the left, click\u00a0Windows Logs.<\/span>\u00a0Then check the following logs:\u00a0Application<\/strong>,\u00a0System<\/strong>\u00a0and\u00a0Security<\/strong><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n

\n
\n

Linux<\/h3>\n
\n
\n

Save the file\u00a0\/var\/log\/warn<\/strong>\u00a0as a duplicate in the\u00a0\/tmp<\/strong>\u00a0directory. To do this, enter the following command:<\/p>\n

[simterm]cp \/var\/log\/warn \/tmp[\/simterm]<\/span><\/p>\n

Then check the file.<\/p>\n<\/div>\n<\/div>\n

\n
\n

To search the messages logged during the last boot for entries, you can use the following commands:<\/p>\n<\/div>\n<\/div>\n

\n
\n

This command searches the boot log file for lines containing the strings Erro or erro.<\/p>\n

[simterm]dmesg | grep [Ee]rro[\/simterm]<\/span>
\nThis command searches the boot log file for lines in which the strings Fault or fault are included.<\/p>\n

[simterm]dmesg | grep [Ff]ault[\/simterm]<\/span>
\nThis command searches the boot log file for lines which contain the strings Defect or defect.<\/p>\n

[simterm]dmesg | grep [Dd]efect[\/simterm]<\/span>
\nThis command searches the boot log file for lines in which the strings Bad or bad are included.<\/p>\n

[simterm]dmesg | grep [Bb]ad[\/simterm]<\/span><\/p>\n

This command searches the boot log file for lines containing the strings Fail or fail.<\/p>\n

[simterm]dmesg | grep [Ff]ail[\/simterm]<\/span>
\nThis command searches the boot log file for lines that contain the strings Incorrect or incorrect.<\/p>\n

[simterm]dmesg | grep [Ii]ncorrect[\/simterm]<\/span><\/p>\n

This command stores all messages which were logged during the last boot process in the directory \/tmp.<\/p>\n

[simterm]dmesg > \/tmp\/dmesg[\/simterm]<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n

\n
\n

\/var\/log\/messages and \/var\/log\/syslog<\/h3>\n
\n
\n

In Ubuntu and Debian, the file\u00a0\/var\/log\/<\/strong>messages will records almost all events. This is the system log of Linux. This file records a variety of events, such as system error messages, changes in the network configuration, etc. In this log file, each entry is listed with a timestamp.<\/p>\n

In CentOS, this information is listed in the file\u00a0\/var\/log\/syslog<\/strong>.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n

\n
\n

kern.log<\/h3>\n
\n
\n

Messages from the kernel can be found in the\u00a0kern.log<\/strong>\u00a0file. This file also contains older messages and messages resulting from iptables rules, for example. The kern.log file can be found in the\u00a0\/var\/log directory<\/strong>.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n
