1. Application Description
1) Service Description
A performance counter defines the measurement items of a measurement object and can be used for network performance assessment, network optimization, and fault detection.
The following concepts help you better understand a performance counter:

•   Counter: (also counter timer), data that must be collected for a measurement, such as number of requests and service traffic    
•   Function subset: (also called measurement unit), a set of measurement counters with the same attribute, for example: the function subset of Ethernet port measurement refers to statistics of different types of traffic over an Ethernet port.   
•   Function set: a set of multiple function subsets with the same attributes, for example, the function set Measurements Related to Network Layer consists of three function subsets: IP Measurement <Network.IP>, IPv6 Measurement <Network.IPv6> and Tunnel Measurement <Network.Tunnel>.   
•   Object type: (also called measurement object) a physical entity or logical entity, such as E1T1, Ethernet port, and IPPATH6.   
•   The following figure shows the relationship between the object type, function set, function subset, and counter.
  

                   2) Documentation Description
For details about how to measure performance counters for BTS3202E, BTS3203E LTE, BTS3902E WCDMA, and BTS3803E WCDMA, see the performance counter reference.  

The following table lists the structure of the performance counter references.


  
The performance counter references of all versions are described by object. The following figure shows the document structure.
  
 
2. Highlights
The counter relationship is provided in eRAN6.0/RAN15.0 and later.
In eRAN6.0/RAN15.0 and later, counter relationship is added to the description of the function subset. Therefore, you can conveniently query and understand counter relationships covering counters of a maximum of nine levels.
