hi my name is boris from the check mk team and welcome to this tutorial series on getting started with checkmk in the next 17 episodes we're going to install and configure checkmk as your monitoring system we will also cover topics such as monitoring snmp customizing and creating your own views distributed monitoring and much more now check mk comes in a few additions we got the open source edition which is free to use for everyone then there is an enterprise edition which is based on our proprietary
00:31
monitoring core and has many additional features around automation and reporting and it's also very suitable for monitoring large it environments then there is a free version of this enterprise edition which has all the same features but will be limited to 25 hosts after 30 days so even after 30 days you can still monitor up to 25 servers snmp devices or whatever you like now we'll be using the free version of the enterprise edition throughout the
01:02
series so now let's get started with check mkay [Music] so in this first episode we're going to install checkmk and we're also going to add our first host to the monitoring system to install checkmk you are going to need a linux environment i prepared a vm with ubuntu 2004 installed now the first thing we are going to have to do is download checkmk to do that let's open a browser and go to checkmk.com so navigate to
01:38
checkmk.com once you're on the home page click on the download button in the top right now you'll see that the free edition is already pre-selected for you so what you have to do next is select the platform in my case that will be ubuntu and the version of ubuntu that i have installed is 2004 so let's select that now we ask for an email address so we can send you some tips on how to get started with check okay once you have put in your email address
02:13
hit the big green download button and wait for the download to finish once the download is complete let's head over to the terminal and copy over the file to our vm so here you see we have the file now let's just simply copy it over to our vm let's copy the file name and we'll copy it over to vrvm we'll put it in a tmp folder for now okay it's done now let's ssh into the vm
03:00
and get started with installing checkmk okay we've put it in a tmp folder so it's here so now we can simply install check mk using apt install this will install check mk with all its dependencies so what is the dependency check mk comes with its own version of apache php and python and all these versions are marked in the package and once you run app install everything will be installed for you okay so let's install it using app to
03:42
install so you see all these dependencies will be installed once i press yes okay so the installation is complete let's check the version so okay you see that we installed version 2.0 patch level 9. so now the next thing to do is create our first monitoring site so what is a site a site is basically an instance of jack mkay and you can have multiple of these sites or instances
04:32
running in parallel on the same system and this is especially useful when you have for example a production environment but you want to test out a new version of check mk you can simply create a new site okay so now now let's create a first site type in omd create followed by the name of the site i will call it test site got it for test purposes but you can name it however you want so what's happening now it will create a place on a file system to store all
05:07
the data it will create a linux user for the site and it will also create our first admin user called cmk admin and generate a password so let's copy this password to the clipboard now when you create a site it's not actually being started yet so type in home day status and you can see that it's not running so to start a site type in omd start followed by the name of the site test site
05:42
and if everything is okay you can switch over to the browser and visit the ui so let's do that now to visit the ui type in an ip of your server or vm followed by a slash and then the name of the site now the default user is cmk admin type that in and paste in the password that's been generated now once you log in for the first time you'll see that the dashboard is pretty empty that's because we're not actually monitoring anything
06:23
first let's quickly change the password so click on user in the bottom left and change password paste in again the password and type in your new password hit save okay now let's head back to the main dashboard by clicking the logo on the top left okay let's quickly talk about the right sidebar so this is the overview here you will see how many hosts that are being monitored and how many services but you
06:59
can also see if there is any problems right now it's still completely empty so let's quickly change that so the first thing we are going to monitor is the monitoring server itself to do that we will need to install an agent we will install this agent on the server and that will send the data to our monitoring server so click on setup and then go to agents and click the first item now here you'll see all the different
07:31
agents that we have so we have an agent for windows for red hat for debian for solaris for aix and if you want to monitor something more exotic then there is this tgc file you can download but we have an ubuntu 20 so let's download the debian file so once that is done downloading let's switch back to the terminal and copy it over to our vm now let's log
08:01
out of the vm quickly okay you'll see here that we have the agent let's sap that over again organ scp followed by the file name [Music] again to the t tmp folder okay that's done let's log back in okay so once again we can use apt install to install the agent it should be fairly quick okay and that's it we're all set up we
08:57
can now add the host to the monitoring system so let's switch back to the browser and add it to checkmarquay to add the host to the monitoring system once again click on setup and then go to hosts and then add host you can either click the small button or the big blue button here now what we need to do is give it a host name i will call it the monitoring system that describes it fairly well
09:30
but you can name it basically whatever you want in my case i will also need to add an ip address because i don't have a fully qualified domain that's resolvable by dns otherwise i could have given that in and then you can omit the entire ip address and it will just resolve itself okay that's it now click on save and go to service configuration and you will see that it will already start discovering services that are being sent from the agent
10:06
so now you'll see that everything is undecided we're not actually monitoring anything we have not decided if we want to monitor this specific service so you can either go through this list by clicking the plus or the x by if you click the plus you can monitor the servers if you click the x then you basically don't want to monitor the service and it won't show up um i will click on fix all and it will just monitor everything
10:39
there's still one undecided let's click the plus okay so now we're monitoring all the services that are being sent over the agent and you see here that we have a few changes whenever you make a change to the setup of checkmk it will show up here that there are changes changes are not being applied automatically but only if you explicitly activate them then they will be applied to the to the monitoring system
11:13
so here you see the pending changes you see everything that we have done we have created a new host we have discovered the labels that came with some of the services and we are now monitoring 23 services for this host so if we click on activate on selected sites it will be applied okay so the changes have been activated and applied to the system now let's look at the top right you'll see now that we have our first host and
11:46
it has 26 services if you click on the number here you'll go to an overview where you see all the hosts in your system we currently have one so click on the name here and you'll get to an overview of all the services that come with this host let's collapse the sidebar so we can see a little bit more now here you'll see stuff like the cpu load the cpu utilization the room left on the file system the memory
12:16
but let's click on one and see what information we see so here you'll see some data like here you see the cpu utilization over time we only added the host a few seconds ago so there is not much data to show but over time over time you'll see more and more here you can find all the information of check mk online on our documentation if you click help and then on user guide you'll be redirected to our documentation website if you're new to check mk
12:47
