polling frequency

Hi,

I want to know the polling frequency of Redgate monitor to the monitored databases. There are other enterprise monitoring tools which are in use and wanted to verify that the load is not too heavy. Thanks.

Hi Nach,

It varies for each counter. Some of counters like CPU are polled every 15 sec, others such as disk I think are polled every 1/2 hour whereas Index fragmentation is checked once a week.

As far as load on Monitored database is concerned, ideally you shouldn't notice anything significant on either CPU or memory. Network work traffic (inbound plus outbound) should be in regions of 10 KB/sec per server.

Thanks,
Priya
