Database performance

This display reports how long it takes for records to be loaded to and from the database during a standard five-minute cycle over a period of time (default: two hours). Database loading occurs whenever incoming traffic data is written, or existing data is called through report generation in the web console.

It is not unusual for the displayed load time to exceed thirty seconds; however, if this occurs consistently, it is indicative that preventative or corrective measures should be taken. The latter is accomplished by making better use of filters when searching through resources. Preventative measures include reducing the number of monitored servers, or creating URL transformations that result in fewer processed URLs.

Error rates

This display summarizes all transmission-related errors over a period of time (default: two hours). Rates are reported for:

All of these reported rates should be zero, or at a low percentage. High rates occur for different reasons, depending on the type of error.

Meanwhile, SSL errors can happen for a variety of reasons, including incorrectly configured SSL keys, security-related communication conflicts, or errors from dropped packets or missing segments.
