Lot of people only know about task manager as a tool to go to when system locks up and we just want to close up some application, see if we can get it working again and fortunately with the new operating system this happens less and less. The task manager is actually a much better tool than a lot of people realize lets take a look at task manager so we are going to right click on task bar and then click on task manager. That is fastest way to get to task manager and then what we can do is take a look at each of the tabs in the task manager. So for example application tabs shows that we have Power Point slide show running we have PowerPoint *****, we have got active directory users and computers then we have got my computer. Now we can end a task, create a new task, switch to a task can do all that from the applications tab. Processes; processes let us know what processes are running on the computer but there are a lot of processes that run. There is a lot of processes that run no matter what application we are running. So how can we use processes in a more efficient manner in a more imaginative manner. Well, what processes is the Power Point slide show running? In other words what processes are being used to run power point slide show. Well, we wouldn't have any idea if we are going to process, we might look for something ppt or something like that but we can easily find out by right clicking on power point slide show and then clicking on go to process and then we can see that powerpoint.exe is running under the administrator user name. So we can see very quickly the systems that are running, the processes that are running and the application that are being used to run this process. You wanted to see what process are being used for active directory users and computers. Go back to applications right click on active directory users and computers to see that mmc.exe is running that. So within the same tool we can click on the performance tab and on the performance tab we got a real quick and dirty look on what is going in the system. So for example we said our CPU usage was running somewhere between 25% and 30% and we had to set up all these performance, consoles and what not to be able to see that. But all we really had to do is to right click on task manager and take a look at performance, because here is our CPU usage right there. You want to see bigger view of it then position your mouse pointer in where it says CPU usage in there on the graph and double click on the graph then we get a much bigger picture. If we wanted to see in more detail what is running on the system that is applications and what is running on system and that just keeping the systems alive then we double click to get smaller view again and then we click on view and then show kernel times. As we can see right now very little of the processor time is being used to just keep the system alive. Most of it is being used by the processes that I am using by power point by active directory users and computers, which is the way it supposed to be. So the system is healthy and as you continue through training learn more and more about how to use this tool and the tremendous information that provides us with physical memory, kernel memory, provides us with the tremendous amount of information that we can use for the system. If we click on networking tab we can see that we are really not doing anything in that arena. We are really not doing anything in regards to the network interface card, network utilization is at 0% (zero percent). Now if we were to connect to another computer then we might see that networking spike. We can also take a look at the users tab. The users tab tells us what users are currently in the system. We can even use this to disconnect or to log off a user if you are the administrator. So we have a great tool in the task manger just with that box settings but here is where it even gets it better. If we take a look at processes again and then we click on view and then click on select columns we can see then that we don't just have look at CPU usage, memory usage and user name. We can look at page faults and we can look at base priorities, look at input-output and reads-writes and click on ok. Now if we expand this we can see all we have just selected. We can format this or we can organize this into whatever way we want as well. Right now it is only arranged in the PID order. In other words the process ID is arranged by that order but if we want to take look at what the CPU is actually using then we can click on CPU and arrange. So now it is arranged by how the CPU is using it so yes you can see the system is idle 63 percent of the time that is because other systems are using it. Other systems are using this system and therefore the processor is being used. So we can tell very quickly if we move the mouse around enough we can see just see that crs.exe that came up, I will move it again you can watch for it. Crs.exe comes up because that is the system that runs the mouse. When we are not using the mouse crs.exe settles way down here. So we can take a look at how the system is being used. We can also take a look at base priorities. One thing that we want to look at in base priority if we are having a system that is having problems with resources just want to make sure that nothing is in real time. Because if it is in real time it going to steal everything from the processor. So if we arrange this in alphabetic order in fact this is in reversal alphabetic order then real time would be at the very top and if we arrange in alphabetic order by clicking on base priorities again the real time would be at the bottom. As we can see there is nothing that is in real time priorities and then you learn more about how to manage the processor so you can keep going through the training. So the main thing we want to point out here is that task manager is a tremendous tool that lot of people don't realize how good of tool is it. And we can use task manager to help manage our server performance. What we really need to know is what we were looking for. We talked about different resources that server uses but in our next chapter we going to focus on this specifics of the resources because in our next chapter we will discuss managing server performance.
