![]() So, it is more likely that unexpected downtime will occur out-of-hours. If the server rebooted itself during office hours, your team would probably have been flooded with support calls. This metric is retrospective, so if you discover a discrepancy between the expected server availability period and the server uptime figure, then the system failed without anyone knowing about it. Your systems administrator needs to watch the Server Uptime metric and tally that with calculations of when the last intentional reboot occurred. If there isn’t, it only takes one command for the systems administrator to get one. There should be a log available that details all of the scheduled jobs set up on a server. You must be aware of the jobs scheduled to run on the server and how long the server takes to reboot and get back up to full availability before you allow any maintenance task that might involve a reboot to take place. You will need to take the server down for maintenance from time to time and some of those tasks involve rebooting the machine. You also need to check whether the server has out-of-hours batch jobs set up on it. If your server hosts a website, it will need to be available around the clock. Server availability is crucial within business hours and also important outside of those times. So, it should have available space and processing power to complete all of the tasks that the staff of the business and also, possibly its customers place on it. The server is there to run the software and/or perform data logging. The primary duty you have to fulfill is making the server constantly available to all. If you are in charge of an IT department and responsible for key performance indicators across your network infrastructure, you more than likely have a server in your inventory. However, the notification to switch over to backup power needs to be heeded because automatic switchover systems sometimes fail. Your UPS should buy you time to switch over to backup power if the main supply breaks. These need to be monitored to ensure that they are working correctly and smoothing out power surges and dips. You will have power supply regulators on your server’s power input. If your server is in a separate room, you could also monitor the temperature control of its HVAC system. If the temperature starts to climb, it could be that the fan in either the server or the rack has stopped functioning and you will need to check that out. You need to look out for temperature passing a safety threshold. Both the server and the rack will have temperature monitoring sensors that will feedback to the system administrator’s dashboard. If you keep your servers in a rack or cabinet, it is possible that the housing includes power supply regulation and temperature regulation systems. The two main physical issues that you need to monitor with your server are: ![]() Apart from keeping the server in a secure room to prevent physical attacks, you need to be sure that the temperature of the servers does not exceed the recommended level for efficient performance in your server environment. However, on-site servers need to be protected from environmental hazards and damage. If you only use cloud servers, you don’t need to worry about the physical status of your equipment. How to monitor your server monitoring software?.Monitoring the server’s physical status.Set the systray icons to see the graphics of the CPU history, GPU history and Physical Memory history as you want. Now to check in "real time" the Memory usage I suggest you to use MS TechNet Sysinternals Process Explorer and set the columns to see the total CPU usage, the total GPU usage and the CPU time. What you have to check is the peak usage of memory, the % of actual usage and the total CPU time.īTW: check the CPU usage in your screen capture: 93% ! This swapping may slow down the performances but nothing else.ġ) The Virtual Memory: RAM + Pagefile.sys can be increased by adding RAM or increasing the pagefile.sys.Ģ) The unused Memory is a lost Memory If you run many applications at the time they can't run faster when there's more unused memory.ģ) The main bottleneck in performances don't comes from the lack of Memory but from the percentage of CPU / GPU usage. What you mean by "crashing"? Normally if there's too much RAM usage the system start to "swap" from the RAM to the Pagefile.sys and not "crashing". Something is going to crash because I'm using too much RAM ![]()
