Refer to the "Tuning the eHealth Statistics Poller" white paper which includes setting information for such statistics poller environment variables such as NH_STAT_POLLS_PER_ SECOND, the maximum number of SNMP requests per second sent by the poller; NH_SNMP_RETRIES, the number of attempts the poller makes to contact an element on a given poll before giving up and calling it a missed poll; and NH_SNMP_TIMEOUT (default 4 seconds), the amount of time the poller waits before performing the initial timeout on an SNMP request.
The document us available here: Tuning the Statistics Poller (CA external).
Also, please refer to one of the following two solutions for instructions to set eHealth environment variables:
How to Set or Change eHealth Environment Variables-NT
How to Set or Change eHealth Environment Variables-Unix
What is the maximum setting for NH_STATS_POLLS_PER_SECOND
how to tune the eHealth statistics poller
missed polling cycles
how to manipulate the number of SNMP requests sent by the stats poller
According to the eHealth Tuning the Statistics Poller white paper, NH_STATS_POLLS_PER_SECOND should not be set over 400 in order to maximize polling performance.
