This article mainly introduces how to install and use Tlog, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

Tlog is a lightweight distributed log tag tracking artifact that can be accessed in 10 minutes and automatically tags the log to complete the link tracking of the microservice.

Installation

Before installing, we need to make sure that our system meets all the software requirements for the compiler and installer. In the first step, update the system repository and software packages with the following command.

# yum update

We need to install the dependencies required for this software installation. Before installing, I have used these commands to install all dependent packages.

# yum install wget gcc# yum install systemd-devel json-c-devel libcurl-devel m4

After completing these installations, we can download the source package of the tool and extract it to the server as needed:

# wget https://github.com/Scribery/tlog/releases/download/v3/tlog-3.tar.gz# tar-xvf tlog-3.tar.gz# cd tlog-3

Now you can start building this tool using our usual configuration and compilation methods.

#. / configure-prefix=/usr-sysconfdir=/etc & & make# make install# ldconfig

Finally, you need to run ldconfig. It creates the necessary links and caches for the most recent shared libraries in the directory specified on the command line, the / etc/ld.so.conf file, and the trusted directory (/ lib and / usr/lib). Tlog work flow chart

Tlog working process first, the user authenticates and logs in through PAM. The tlog information provided by the name service exchange (NSS) is the user's shell. This initializes the tlog section, collects information about the actual shell from the environment variable / configuration file, and starts the actual shell in PTY. Then start recording everything passed between the terminal and the PTY via syslog or sd-journal. Usage you can record a session using tlog-rec and play it back using tlog-play to test whether the newly installed tlog can record and play back the session properly.

Record to a file

To record the session to a file, execute tlog-rec on the command line, as follows:

Tlog-rec-writer=file-file-path=tlog.log

This command records our terminal session to a file named tlog.log and saves it in the path specified in the command.

Play back from a file

You can use the tlog-play command to play back the recorded session during or after recording.

Tlog-play-reader=file-file-path=tlog.log

This command reads the previously recorded file tlog.log from the specified path.
