Table 1. Improving NIE Performance When Monitoring GIO Point Attributes




The NIE service time for every NCM increases when monitoring GIO objects.

Polling for GIO Point Attributes interrupts the polling for object values. There is no way to tune the polling rate for these objects.

Upgrade your NIE to Release or later. Once your NIE is upgraded, overall service time improves. You can further improve performance by tuning the CSG poll rate, which is accomplished by increasing the value of the N1 integration object's poll delay.

For each NCM device with a poll delay set to zero, set the NCM device poll delay to match the N1 integration object poll delay. Then increase the N1 Integration poll delay by 1,000 milliseconds at a time, until the average service time is acceptable while ensuring that the collection time for the CSG points is also acceptable.

To estimate the time to poll for CSG object data, multiply the total number of CSG objects being polled by the NIE times the N1 intergration object's poll delay and round up 2 to 5 seconds per N2 device.

Note: If this is not acceptable to the site, consider migrating these devices to an NAE.
