Parameter Set
Parameters Sets are a grouping mechanism for certain properties. A Parameter Set can be applied to a Dynamic Group or a Static Group of Systems.
The properties available for grouping are: Monitoring Parameters, Check Execution, Check Notification, and Monitoring Exception Parameters.
As you can easily see, there may be situations where a certain System belongs to more than one group. If you have the same property defined in two different Parameters Sets sharing a common subset of a System, you have to prioritize the Parameters Sets in order to decide which one is finally effective.
Furthermore, for every Parameter Set you can define if the definition of a property in a Parameter Set can or cannot be overridden on a per-System level. If cannot, you can define a consistent set of properties throughout a class of System. But even if you allow overriding you can re-apply the properties at any time.
Parameters Sets can be scheduled. So, for example, it is possible to have different values for Monitoring Parameters of different periods of time. You may use Schedules or Service Hours to define the validity period of a Parameter Set.
Please prioritize Parameters Sets carefully if they are scheduled! |

Performance Indicators are shown in the UI and reported in the Service Level Reports for those Systems where Performance Data Collection is turned on. This can be turned on or off on a per-System (via PerfDataCollection Monitoring Parameter) level.
Performance Indicators are aggregated automatically into hourly, daily, and monthly values, whereas hourly and daily values are kept for six months and monthly values are kept for three years in Avantra (see also Performance.PERFDATA_KEEPTIME_MONTHLY).
Physical Server
A Physical Server in terms of Avantra is either:
-
a real server that runs a copy of the supported operating systems
-
a system virtual machine (or hardware virtual machine) running its own operating system (the so called guest operating system)
-
a partition in operating system-level virtualization (virtual environment, virtual private server, guest, zone, container, jail, etc.).
In other words, if it looks like a real server from the point of view of its users, it is called a Physical Server in Avantra.
If you want to manage or monitor a Physical Server you need to install an Avantra Agent on it.
The same holds true if you want to define an End Point on it.
