The following system data metrics are collected and visualized by the BlueCat Health Monitoring service.

System Load: A percentage representing the amount of processes being executed by the CPU or in a waiting state (including processes blocked in I/O), according to maximum CPU capacity. System load is represented as an average calculated over time periods of 1, 5, and 15 minutes.

CPU Usage: A percentage representing the average amount of time the CPU was in use during the reporting interval (frequency).

Example: A data point shows a CPU usage of 10%. The metric reporting frequency is 60 seconds (default). This indicates that the CPU was in use for approximately 6 seconds during the previous 60 seconds.

CPU Times: Three percentages (IOWait, System, User) that provide a more specific breakdown of processing times used in CPU usage calculations. The user percentage indicates the time spent by normal processes executing in user mode. The system percentage indicates the time spent by processes executing in kernel mode. The IOWait percentage indicates time spent waiting for I/O to complete.

Example: A data point in the CPU usage chart displays a usage of 10%. The corresponding data point in the CPU Times chart displays a System percentage of 5%. This indicates that half of the CPU usage for that interval was for System processes. With the default frequency of 60 seconds, this indicates that approximately 3 of the 6 seconds the CPU was in use was for System processes.

Memory Utilization: A percentage representing the amount of system memory in use at time of polling.

Swap Memory: A percentage representing the amount of system swap memory in use at time of polling.

CommandServer: CommandServer is a core system application running on DNS/DHCP Servers that is responsible for handling interactions with Address Manager servers. Similar to CPU Times, the CommandServer CPU percentage can be used in conjunction with corresponding CPU Usage data points, to determine how much CPU usage was caused specifically by CommandServer.
