Summary:

How to improve eHealth Polling Cycle if you have a problem with Average Normal Poll Above 5 minutes

 

Instructions: 

 

1)    Clean up bad polls (Rediscover devices, make sure devices that no longer exist are retired or deleted, etc)

2)    If that doesn't work set:

NH_SNMP_TIMEOUT=6000000
NH_SNMP_RETRIES=2

The idea above is wait a little longer but retry less. This avoids unnecessary retries.

NH_STAT_POLLS_PER_SECOND=400                   

3).  Leave NH_STAT_POLLS_PER_SECOND=50  and try increasing NH_POLL_AGENT_ THROTTLE from 5 to 15. Check the result.

 If it gets better, i.e. poll cycle decreases from some minutes or seconds, then try increasing it by 10 again.


 
 4). Once optimal NH_POLL_AGENT_ THROTTLE value found, try increasing NH_STAT_POLLS_PER_SECOND from 50 to 100.

 Check the result.

If poll cycle duration decreased, then try increasing it by 50 again, from 100 to 150 and so on until you get better results.
