Figure 5. Setting default batch amount and interval values
Agent settings
There are two parameters in the HPDM Agent settings that affect HPDM performance:
Delay Scope
The HPDM Agent sends a startup report at a randomly chosen time between 0 and the “Delay Scope” after it is started. If
there are large amounts of devices starting within a short time slot (for example, 9 devices in ± 2 minutes), then configuring
a larger Delay Scope prevents those startup reports from reaching the HPDM Server in a short period of time.
Pull Interval
Pull Interval is the frequency the HPDM Agent sends startup reports to the HPDM Gateway to get tasks. There is no need to
enable this function for non-NAT environments, because the HPDM Gateway can connect to the HPDM Agent directly to
send tasks. If you are managing large amounts of devices and have to enable HPDM Agent pulling, pay attention to the
value of the Pull Interval.
For example, you have 10,000 devices with a Pull Interval set to 30 minutes, and the latency between your HPDM Server
and database is about 20 ms.The server will receive 10,000 startup reports every 30 minutes. The HPDM Server needs more
than 1200 ms to handle one startup report. That means the HPDM Server can handle 1,500 startup reports at most in 30
minutes. Thus, the HPDM Server is flooded with startup reports and barely responds to any HPDM Console operation.
