<p class="wp-block-paragraph">Hi, my loving friends. Welcome to this course. In this article, I will explain to you about the next-gen project. This is the new feature of Jira and atlas Sian introduced it in the year 2018 so, let’s have a look at the agenda of this content. In this, we will learn what are the next-gen projects, how to create next-gen projects? How can we create issues and add issue types in next-gen projects and how to configure the board? So. Let’ start.</p>



<h2 class="wp-block-heading">What are the next-gen projects?</h2>



<p class="wp-block-paragraph">Next-gen projects are the newest projects in Jira software and it is only available on the cloud platform to the server one. If you are using a server the server platform and you wouldn’t be able to sit. The third one is configured by project team members. Any team member with the project’s admin role can modify the setting of their next-gen projects. There is no need to take the help of the Jira <a href="https://www.devopsschool.com/">administrator</a> to add the issue types and to add some fields to your screen. The Fourth one is it is easier and faster to configure than classic projects. You can easily configure setting like issue types and fields with drag-and-drop editing and reordering all in a single place because the best part of next-gen projects is the ability to enable and disable the features and it allows you to scale your projects as your team grows and tailor your projects to your team changing needs so, this is the best thing in the next-gen projects. And before going forward, I would like to tell you one more thing like atlas Sian is building the next-gen Jira software from the ground up.</p>



<h2 class="wp-block-heading">How to create next-gen projects?</h2>



<p class="wp-block-paragraph"> So, it doesn’t yet have all the features that classic projects have. And they are a lot of differences between the next-gen and the classic projects like if I’m talking about the configurations then in the classic projects. We are able to share the configurations from one project to another. But in the next gen, you can’t share it. If you did some configurations for the particular projects in the next-gen, you wouldn’t be able to share that configuration with another project. And there are many more like estimations in the classic projects, you have the options, you can give the estimations in story point in your basis but in the next-gen, there is only one option is available and that is a story point. If you will go to the next-gen cloud instance and see how can you create the next-gen projects and configure them? There will be your cloud instance and you will create the next-gen projects from there. You will see that there will be two options are available one is classic and the other is next-gen. if that particular option is created out for you then this is the permission issue so, before creating the next-gen project. I would like to tell you about the permission so, once you will click on the Jira setting and go to the global permissions, there will be your global permission schema, and create next-gen project option will be there. At the time, you will have permission to create the next-gen project. You will click on the next-gen project and you will see the interface is similar to the classic.</p>



<p class="wp-block-paragraph">You can simply change the template from there but you will see only two templates are available one is scrum and another one is Kanban. If you will go with Kanban and name the project, you will see the access option (open, limited, private) and project key as a classic one. If you want to change the project key then you can do it there. You will go forward to clicking the create button then the next-gen project board will appear which would be similar to the classic one but what is the difference and how can you identify that this is the next-gen project but what will happen? If you will haven’t created it yet you didn’t create it. Maybe, you are using the project which is created by another one. You will see in the bottom line that you are in the next-gen project. You can find out and identify that you are using the next-gen project. You will see there are the options which are roadmap, board, pages, add an item, and project setting. A Roadmap is a good option which is given by the next-gen project. I will discuss this later in the course. I hope this will give you exact direction in the way of your Jira learning and about its next-gen project. So, you will stay tuned with this course for further next information regarding Jira next-gen project.</p>

<p><strong>Generic troubleshooting tips</strong></p>
<ul>
<li>Use tail –f to watch log file in real time, advantage is simple you can spot error or warning message in real time.<br />
<strong>tail –f /path/to/log/file</strong><strong><br />
Example(s):<br />
<strong># tail –f /var/log/maillog</strong></strong></li>
<li>Use telnet command to see if you get response or not. Sometime you will also see some informative message:<br />
<strong>telnet ip port</strong></li>
</ul>
<p>Example(s):<br />
<strong># telnet localhost 53</strong><br />
<strong># telnet localhost 25</strong></p>
<ul>
<li>Make sure you can see PID of your service.<br />
<strong>pidof service-name</strong><strong><br />
<strong>cat /var/run/service.pid</strong></strong><strong><br />
Example(s):<br />
<strong># pidof sshd</strong><br />
<strong># cat /var/run/sshd.pid</strong></strong></li>
<li>You need to make sure that your DNS server or third party DNS server (ISP) is accessible. This is an important step, as many network services depend upon DNS; especially sendmail/postfix or Squid etc for example. Run dig or nslookup. No timeout should occurred.<br />
<strong><br />
<strong># dig your-domain.com</strong><br />
<strong># nslookup gw.isp.com</strong><br />
<strong># more /etc/resolv.conf</strong></strong></li>
</ul>
<p><strong>Performance /  Memory / CPU / Process check</strong><br />
<strong>ps</strong> – Read user manual</p>
<p><strong>w username</strong> &#8211;  Find Out Who Is Logged on And What They Are Doing. w command displays information about the users currently on the machine, and their processes.</p>
<p><strong>top</strong><br />
The top program provides a dynamic real-time view of a running system i.e. actual process activity. By default, it displays the most CPU-intensive tasks running on the server and updates the list every five seconds.</p>
<p><strong>uptime</strong><br />
tell How Long The System Has Been Running</p>
<p><strong>free &#8211; Memory Usage</strong><br />
The command free displays the total amount of free and used physical and swap memory in the system, as well as the buffers used by the kernel.<br />
# free –m                                                            Display free memory size in MB<br />
# free -t –m                                                        Displays a line containing the totals memory in MB</p>

<p><strong>Networking troubleshooting tips</strong></p>
<p><span style="text-decoration: underline;">Hostname verification or setup tools</span></p>
<ul>
<li>hostname : To get hostname of server.</li>
<li>hostname –s : To get FQDN hostname of server</li>
<li>more /etc/sysconfig/network : To setup hostname and networking can enable or disabled.</li>
<li>dnsdomainname : List or setup domainname.</li>
<li>more /etc/hosts : Make sure at least localhost entry do exist.</li>
</ul>
<p><span style="text-decoration: underline;">Ethernet configuration tools</span></p>
<p><strong>service network reload|restart|stop|start :</strong> To reload (after changed made in ip config file)|restart|stop|start network interface with all properties.</p>
<p><strong>route</strong><br />
The route command allows you to add static routes to the routing tabling.</p>
<p><strong>traceroute (tracert in Windows)</strong><br />
Traceroute displays the routers that are passed through to reach the destination.</p>
<p><strong>dmesg</strong><br />
When the system boots up, it prints number of messages on the screen that displays information about the hardware devices that the kernel detects during boot process.<br />
These messages are available in kernel ring buffer and whenever the new message comes the old message gets overwritten. You could see all those messages after the system bootup using the dmesg command.</p>
<pre># dmesg | more</pre>
<pre># dmesg | grep Memory</pre>
<pre># dmesg  | grep eth</pre>
<pre></pre>
<p><strong>ifconfig</strong><br />
The ifconfig command is used to display the local interface configuration (winipcfg for Windows) and to modify the configuration.<br />
ifconfig eth0 up|down : To enable|disable network interface</p>
<p><strong>netstat</strong><br />
The network status command netstat displays status information about the network interfaces on the host machine. Netstat command displays the network related information such as network connections, routing tables, interface statistics.<br />
-a                Show both listening and non-listening sockets<br />
-n                prints the numeric forms of IP address</p>
<p># netstat -ain                                  Local interface status<br />
# netstat -rn                                    Routing table information<br />
# netstat –an                                  Display Active Internet Connections and domain sockets using netstat<br />
# netstat -tap                                 Display Active Connections with Process ID and Program Name<br />
# netstat –-route                          Display Routing Table<br />
# netstat &#8211;statistics &#8211;raw         Display RAW network statistics<br />
# netstat &#8211;tcp &#8211;numeric           List of TCP connection to and from the machine.<br />
netstat -tuplin                                UNIX</p>
<p><strong>iptables </strong></p>
<p>To know which ports are running in the machine.<br />
<strong>ping</strong><br />
The ping command allows you to determine that the:</p>
<ul>
<li>TCP/IP stack is configured properly</li>
<li>Network interface card is configured properly</li>
<li>Default gateway and subnet mask is configured properly</li>
<li>Domain name services is configured properly.</li>
</ul>
<p><strong># ping ipaddress</strong> to check if the ip address in connected with network and if host is alive or dead<br />
<strong># ping 127.0.0.1/localhost</strong> &#8211; to check TCP/IP services is running properly or not. Checks that your TCP/IP stack is working properly up to the NIC. If this fails, check to see if you have TCP/IP services loaded.<br />
<strong># ping &#8220;IP address of default gateway&#8221;</strong> &#8211; Checks that the NIC is working on the local subnet by pinging the local side of the default gateway which is a router. If this fails, check that TCP/IP is bound to the NIC. Then check that the NIC&#8217;s IRQ, and base address are set properly both on the card itself and in the operating system&#8217;s interface configuration.<br />
<strong># ping &#8220;domain name&#8221;</strong> if DNS name is correctly configured. If it fails, check that the DNS server&#8217;s IP address is entered in properly in the TCP/IP configuration.</p>
<pre><strong>arp</strong></pre>
<pre><strong>address resolution protocol</strong></pre>
<p><strong># arp </strong>  &#8211; To see the IP to MAC address translation table<br />
<strong># arp -a</strong>  -Use this command to see the IP to MAC address translation table if you are having problems connecting to other network hosts. It is a dynamic cache which updates every 120 seconds.</p>
<p># more /etc/modules.conf : To see your network card configuration alias for eth0 exists or not.<br />
# lsmod : To list loaded modules (read as drivers), here you need to see that eth0 module is loaded or not, if not loaded then use insmod to insert (load) driver.<br />
# dhclient : Dynamic Host Configuration Protocol Client, run this if your Ethernet card is not getting ip from DHCP box on startup; this command does by default shows useful information.</p>
<p><strong>To see if service blocked because of access control</strong><br />
# iptables –n –L : To list all iptable rules; useful to see if firewall blocks service or not.<br />
# service iptables stop|start : To start|stop iptables<br />
# more /etc/xinetd.conf</p>
<p><strong>sar </strong><br />
sar is an excellent monitoring tool that displays performance data of pretty much every resource of the system including CPU, memory, IO, paging, networking, interrupts etc., Sar Collects, Reports (displays) and Saves the performance data<strong>.</strong></p>
<p># sar –u | more         Display CPU Statistics using Sar Command<br />
# sar –d | more         Display Disk IO Statistics using sar command<br />
# sar -n DEV | more Display networking Statistics using sar command<br />
# sar -n SOCK |more Display networking Statistics using sar command<br />
# sar -n DEV -f /var/log/sa/sa24 | more   To display the network counters from the 24th<br />
# sar 4 5                                             You can also display real time usage using sar</p>
<p><strong>lsof</strong><br />
lsof stands for &#8220;ls open files&#8221;, which will list all the open files in the system. The open files include network connection, devices and directories. The output of the lsof command will have the following columns:</p>
<p>COMMAND process name.<br />
PID process ID<br />
USER Username<br />
FD file descriptor<br />
TYPE node type of the file<br />
DEVICE device number<br />
SIZE file size<br />
NODE node number<br />
NAME full path of the file name.</p>
<p># lsof | more              View all open files of the system<br />
# lsof | wc -l                How many files are open in the system at any given point<br />
# lsof –u ramesh       View open files by a specific user. A system administrator can use this command to get some idea on what users are executing on the system.<br />
