Scalability

There are limits to the number of scripts that a single monitoring server can run in any period.

There are many variables that influence how many scripts you can run, for example,
  • The type of script you are running (for example, RPT / RFT / CLI)
  • The complexity of scripts
  • The number of scripts you are running
  • The running frequency of scripts
  • The length of time it takes for each script to run
  • The amount and frequency of data that is collected and warehoused
If you need to run high numbers of scripts, consider the following suggestions:
  • Make sure that the T6 agent machine has a high specification, for example,
    • More than one cpu
    • Minimum 4 GB memory
  • Keep scripts simple by not monitoring too many services/applications. Don't try to do too much in a single script.
  • Don't collect more data than you need.
  • Use profile and T6 agent configuration options to optimize scalability.
  • Have a maximum of 10 pages per script.
  • If none of the previous suggestions help, use multiple servers with a reduced number of scripts for each server.
