Designating the Variables You Want to Monitor 

Procedure

...

       1.      Decide what are the important parameters that you want to monitor.

In our example we will define the following monitors:

                            a.      Bank Name – name of the bank

                            b.      Bank information – additional information about the bank, such as address, telephone and fax numbers, and so on

                            c.      Bank Ranking – indicates the current status of the bank – Big, Medium, Small, or Bankrupted

                            d.      Counter Desks – information about cashiers and working floor

                            e.      Currently served clients – number of clients currently served at counter desks

                              f.      Open for clients – indicates the percentage of time the bank has been open for work with clients

                            g.      Served Clients – number of all clients served since the bank started operating

                            h.      Software Version – information about the software system used in the bank

                              i.      Transaction Duration – average duration of client transaction

                              j.      Transaction Frequency – frequency of client transactions (transactions per second)

                            k.      Transactions over 10,000 EUR – percentage of transactions exceeding 10,000 EUR

       2.      Define monitors for every client that has executed transactions over 10,000 EUR: Transaction number and Transaction duration.

The above list of monitors is created to serve as an example of all types of monitors (as you will see later). The two monitors specified for each client exceeding 10,000 EUR cannot be described statically because we do not know the number of such clients in advance. They are meant to show the usage of “template-based” dynamically installed monitors.
