[MUSIC] Alright, so staying with the theme of problem determination in monitoring as we've been discussing for the last couple of videos. You might be familiar with a tool called ANM on an Mon now if not briefly said it's a popular free open source system monitoring tool with origins on the aix operating system. It is simple to use. It is lightweight on the system and it's extremely feature rich. Now the tool can be used in an interactive mode. Which is what I'll show in a little bit here or in a data collection mode where the historical data is analyzed at a later point. I'll talk about those tools in a little bit as well. Now in interactive mode you change what is monitored. And what? I'm sorry what is being displayed but monitored resources are being displayed by by hitting a key or key sequence. So again in interactive mode you change what monitored resources are being displayed by hitting a key or maybe a key sequence. You may need to hit shift the end MoD tool is available in the power tools repository. So we talked about that earlier, but again, like like some of the other tools we've talked about, it's not automatically installed, right? Like the electronic service agent. It is easily installed using Yum install in mind. Okay, and I think this is one of those tools that is best explained with the demo. So let's have a look at how to use an one. Okay, so in this demo, I'm going to do is have a look at end one. Now I've already typed in the command MoD and it brings up the splash panel for Edmond, showing usage tips as well as the toggle keys, and those are very important. As I mentioned in the video prior. So what I'm going to do is I'm going to have a look at disk used utilization top processes that would be generating activity and then processor activity. Not comprehensive, you see, there are many other options here. You can look at memory. You can look at help our information, things of that sort you can strike in age to get more options, right? So so this is a very function rich tool. As I mentioned earlier. So strictly Q Takes you out right in one. Go back in. OK, so I'm going to use a tool that generates traffic. It's going to run 4. About 2 minutes. It's going to just generate some IO traffic. So have a first look at Disk Utilization. And what will see here is that there's a fair amount of disk up operations going on the. The data mix the read write Mix was about 8020 read and write. So you see that there's majority reads, but there are some rights and you see which disks are taking the activity. So if I wanted to see. What the top processes are, I would strike AT and it tells me what the top processes are. And you see that the tool that's running this is something called in disk. It's just a little tool that is associated with the same developer that built in MoD. So the end in front is sort of an indication, so I see that there's a process that's generating a lot of activity against the disks, and if I want to see what processors are being utilized or if I maybe I started off by looking at processors, I would strike this, see. And you see, I've got a lot of virtual CPUs here. V CPUs and all of them are taking a lot of activity. This tool saturates the. Processors fairly evenly. So this would be a concerning situation and again right, you would strength to see again to get rid of the CPU utilization and bring the top processes back. So there's a real a state issued a not lot of room on the screen for all of this information. So you just toggle back and forth using the CT could use them for memory and for network things like that. And then in the end, strike AQ. And your back too. Get back to your prompt again. So like I mentioned, you can use unmanned to save data to a comma separated file for analysis and longer term data capture. In the video you saw how to use it interactively to process the save data. You use on chart to generate a Google chart web page and you use Mon Analyzer to create detailed graphs viewable via Microsoft Excel. So the end Montana l'iseran the end man chart both can be found at the URL that you see on the screen. And so I'll close this video on Linux Productivity Tools for power systems with some commands that are very fundamental to manage in the hardware on which the Linux operating system is installed. Now I know that I often find myself wanting to see what adapters are associated with my helper. For example, I want to see what virtual adapters are configured for me based Linux provides me with the LSHW Command, while that command provides great information. Say I want to get location information for my. My aforementioned visca Z adapters. Now as you see on the screen I get a lot of very useful information from LSHW, but I'm missing the specifics of the location of the adapter. Now, let me just take a moment here because I started talking about location codes. It's kind of an interesting an informational thing for you to understand. Virtual adapter location codes are different than physical adapter location codes now were most likely going to be dealing with virtual because we're going to be cloud. Enabling our Linux operating system, but let's keep going here. They're both useful, but in different ways of physical location code. So if you have a bare metal implementation of Linux on a power system, that can be helpful in guiding a service technician to the right adapter that's failing when it needs to be replaced. Virtual location codes provide me with the slot number of the virtual adapter, so if you look at the example I'm going to go into more detail here because virtual is where we're going to be focusing our time. The example that is now on the screen shows the location code that ends with Victor three. See C12 T Tom won the C12 is the is the slot number and you can use this to see what adapter on the VIO server is associated with this adapter. In the Linux L part. To help you see the correlation between the vio server virtualization aspect and the virtual adapter in the Linux L part. So hopefully that will be a little helpful to you someday. Lastly, when it's time to consider a firmware update, there are a few ways you can find that information, but if you're on a Linux L part, you can use the LSM Code Command. You can generate that information from the HMC and you may not ever need to use this, but it's kind of nice to know that you can find that information from a Linux L part on that system now as you see on the screen. The system firmware level is FW 860 dash 80, so this is the 860 firmware firmware level and it's specifically at a fixed level of SV860. Underscore 212. All right, again may not be useful information, especially as a new Linux administrator, but as you make your way through system administration in general might be useful to know that all right. So let me close this video with a list of other service aid commands that you want to know when managing a Linux L Parana Power System Server. Of these commands, I'm going courage you to make note of L parsed at an boot list. You'll find them to be very useful at times. [MUSIC]
