Round Trip SMTP Monitor Set Up

What are the Basics?

We send you a test message and you forward it back to us at mailive@knowledgefront.com. We track the round trip time, record any errors, and alert you to problems or delays.

Check out the features page for additional details.

What needs to be set-up on my server?

You will need to set up what is commonly known as an auto-forwarder or auto-responder. We have instructions for several of the most popular email servers:

How are alerts triggered?

Rather than alert on individual message delay, this system’s unique alerting system is based on a period of inactivity. Every minute, the system checks the last time we heard from your server (by checking the Time Received in the Event History). Based on your Alert Timeout setting, a down alert is triggered if your Timeout period has been exceeded. As soon as we get a response (to any outstanding test message) the system recognizes that your system must be up, and will send an up alert. Adjusting your alert settings is a matter adjusting either your Test Frequency or your Alert Timeout - or both. If we send Test Messages more frequently, we should be receiving responses more frequently.

General Setup

When does the monitoring start working?

After saving a new monitor or changing the configuration of an existing monitor it may take up to 120 seconds for the configuration to propagate through the entire system. Because Knowledge Front’s systems are distributed and can operate in an almost autonomous fashion there is a small delay pushing changes through the system.

back to FAQ

Where do alerts come from?

E-email alerts are sent from alert@knowledgefront.com which is an unattended address. SMS and voice alerts are initiated from a pool of numbers. See Alerting for more details.

Current number pool:

  • +1 (952) 955-9678
  • +1 (952) 314-5455
  • +1 (952) 236-1477

back to FAQ

How can I test alerting to make sure it is working?

Once an alert has been saved Test this alert button becomes available under the alert’s configuration page. Pressing this button will trigger both up and down messages and log the event in the system.

An alternate way to test the system is by changing the settings of the monitor to a known bad configuration to force an alert to trigger.

What types of monitors are available?

The Knowledge Front monitoring system is built to be extremely flexible. We are constantly working on improvements and adding new features. If the desired monitor is not listed here please contact us and let us know what you are looking for. We may be able to get something going in very little time.

back to FAQ

Are there any limits on how many people receive alerts?

No, there are currently no limits on how many destinations may be configured per alert.

How many alerts may be configured per monitor?

There are currently no restrictions to the number of alerts per monitor. See the next answer for why you may want multiple alerts per monitor.

Can I add multiple alerts?

Yes. It is common for clients to set-up a 10 minute alert to go to destination X, and a 30 minute alert to go to destination X, Y, and Z. This serves as an excellent escalation procedure.
