IBM® Informix® 12.10

Monitoring virtual processors

Monitor the virtual processors to determine if the number of virtual processors configured for the database server is optimal for the current level of activity.

To monitor virtual processors:

Use command-line utilities, such as onstat-g ioq to view information. See Using some onstat-g commands to monitor virtual processors
Use the AUTO_AIOVPS configuration parameter to enable the database server to automatically increase the number of AIO virtual processors and page-cleaner threads when the server detects that AIO virtual processors are not keeping up with the I/O workload.
Query SMI tables. See Using SMI tables to monitor virtual processors.
