1. If your server considers a great deal about performance it would be recommended to increase the capacity of your physical memory when using swap Even if the server does not consider a great deal about performance configure the threshold for this value flexibly as a 100 swap usage rate will cause your system to cease operation 5 System usage rate To be simply put system load refers to the percent of CPU usage and is considered low if it is below 1 00 and high if it exceeds 1 00 Some delay may occur when executing certain processes when the system load is high Set your threshold value to around 2 0 if your system environment seldom executes heavy load processes However if your system environment often operates heavy load processes it is recommended to set the threshold value as high as the system can handle such processes 6 CPU usage rate This value is displayed as an average CPU usage rate excluding idle up until the time when the system was late monitored If this value is near 100 and the monitoring interval is set to 5 minutes it means that the system has used the CPU close to its 100 amp capacity over a 5 minute time period Such high CPU usage may imply insufficient CPU capacity or abnormalities in the executed processes Please note that some process will require the use of CPU close to its 100 capacity even under normal circumstances You may prevent receiving an alert for such processes by increasing the2. Controller m Auto Monitoring of Servers e Setting up monitoring content and corresponding threshold values The server will be able to self monitor the following contents This section will provide an explanation for the definition of and how to set up a threshold value for each of the contents introduced Please use this as a reference when setting up your own threshold values 1 Disk and inode usage rates Disk and inode usage capacities depend greatly on the file system you are using however when the disk and inode usage rate reaches 100 users may not be able to save data such as e mails on the hard disk or may even cause the system to stop operating Please make sure to configure your settings flexibly O 2 Actual memory usage rate The usage rate of the actual memory that is the section of the physical memory which does not include buffer memory buffer and cached This value will be less than that of the memory which includes buffer memory High usage rate of the actually memory may cause a decrease in the size of the buffer memory used by the system and lead to a decrease in performance Please refer to the graph report and set your threshold value flexibly 3 Physical memory usage rate Usually there will not be any problems even if this value is at 100 however the system performance may decrease if the difference between this value and the actual memory usage rate is small 4 Swap usage rate
