xsos – A Tool To Read SOSReport In Linux
======
We all are already know about **[sosreport][1]**. It’s used to collect system information that can be used for diagnostic.
Redhat support advise us to provide a sosreport when we raise a case with them to analyze the current system status.
It’s collecting all kind of reports that can help user to identify the root causes of issue.
We can easily extract and read the sosreport but it’s very difficult to read. Since it has created a separate file for everything.
If you are looking for performance bottleneck tool then i would recommend you to check the **[oswbb (OSWatcher) utility][2]**.
So, what is the best way to read all together with syntax highlighting in Linux.
Yes, it can be achieved via xsos tool.
### What Is sosreport?
The sosreport command is a tool that collects bunch of configuration details, system information and diagnostic information from running system (especially RHEL & OEL system).
It helps technical support engineer to analyze the system in many aspect.
This reports contains bunch of information about the system such as boot information, filesystem, memory, hostname, installed rpms, system IP, networking details, OS version, installed kernel, loaded kernel modules, list of open files, list of PCI devices, mount point and it’s details, running process information, process tree output, system routing, all the configuration files which is located in /etc folder, and all the log files which is located in /var folder.
This will take a while to generate a report and it’s depends on your system installation and configuration.
Once completed, sosreport will generate a compressed archive file under /tmp directory.
### What Is xsos?
[xsos][3] is a tool that help user to easily read sosreport on Linux systems. In other hand, we can say sosreport examiner.
It instantly summarize system info from a sosreport or a running system.
xsos will attempt to make it easy, parsing and calculating and formatting data from dozens of files (and commands) to give you a detailed overview about a system.
You can instantly summarize your system information by running the following command.
```
# curl -Lo ./xsos bit.ly/xsos-direct; chmod +x ./xsos; ./xsos -ya
```
[![][4]![][4]][5]
### How To Install xsos In Linux?
We can easily install xsos using the following two methods.
If you are looking for latest bleeding-edge version. Use the following steps.
```
# curl -Lo /usr/local/bin/xsos bit.ly/xsos-direct
# chmod +x /usr/local/bin/xsos
```
This is the recommended method to install xsos. It will install xsos from rpm file.
```
# yum install http://people.redhat.com/rsawhill/rpms/latest-rsawaroha-release.rpm
# yum install xsos
```
### How To Use xsos In Linux?
Once xsos is installed by one of the above methods. Simply run the xsos command without any options, which show you the basic information about your system.
```

### How To Use xsos Command To View Generated sosreport Output In Linux?
We need the sosreport to read further using xsos command. To do so, navigate the following URL to install and generate sosreport on Linux.
Yes, i have already generated a sosreport and file is below.
```
# ls -lls -lh /var/tmp/sosreport-CentOS7-01-1005-2019-05-12-pomeqsa.tar.xz
9.8M -rw-------. 1 root root 9.8M May 12 10:13 /var/tmp/sosreport-CentOS7-01-1005-2019-05-12-pomeqsa.tar.xz
```
Run the following command to untar it.
```
# tar xf sosreport-CentOS7-01-1005-2019-05-12-pomeqsa.tar.xz
```
To view all the info, run xsos with `-a, --all` switch.
```
# xsos --all /var/tmp/sosreport-CentOS7-01-1005-2019-05-12-pomeqsa
```
To view the bios info, run xsos with `-b, --bios` switch.
```
# xsos --bios /var/tmp/sosreport-CentOS7-01-1005-2019-05-12-pomeqsa
