UTILITY - CheckSystem

Check the system for warning signs of problems. This function is designed to give a few key metrics on the system without causing much load on the database to perform these checks. In order to minimize the impact on the database for running this API call, the results are based off the last 1,000,000 mail queue sending records. In some unusual cases this might not represent the current activity of the system, but should be a good metric in most circumstances.

It is difficult to development methodologies that would always recognize system issues as they are very customer-specific. No clickthroughs for several hours could be an indication of problems for some high volume senders, where in other cases emails are sent less frequently so low customer involvement is expected. You will need to know something about the load on your system and what that means for these metrics. For example, if you monitor the delayedMailQueueRecords shortly after you post a large mailing, depending on your system speed, you may see some records listed as being delayed. However, that wouldn't be a concern since you know that a large posting was just submitted.

We recommend that you analyze your own system performance to build up a baseline, and then you can have this API warn you if anything falls outside of your baseline. For example, if you determine that your system regularly takes 100 ms to resolve these database queries, you might set an alarm if it takes 200 ms. But someone else's database might take 500 ms, so they would want a different alarm point.

Although these system metrics are designed to be retreived with a minimal load on the system, it is recommended that you run this routine with at least five minutes between calls.
