How we calculate active servers

We charge you the base rate for the number of servers on your plan at the beginning of each month.

When you add additional servers, we'll calculate the number of additional servers in use on a daily basis and include those charges on your next month's bill.

A server is only counted on each day if it has actively provided data.

Volume discounts

The Small plan provides a great rate for up to 4 servers. We no longer provide volume discounts for additional servers.

If you have more than 4 servers and would like volume pricing, contact us for a Business plan quote.

Small plan limitations

The Small plan is an cost-effective option for individuals and small teams, featuring a blend of LeanSentry's diagnostic capabilities to help identify & resolve production issues.

It is limited to monitoring 1 environment only. If you have multiple application environments, or need to accomodate a development/operations team with individual user accounts, permissions, and notification preferences, please consider the Business plan.

Cancellation policy

To cancel a monthly plan, simply email us at any time. Your cancellation will be effective for the next calendar month. Please note that the base plan rate is billed each month until the account is cancelled, even if your servers are no longer being monitored.

Data deletion. When the account is cancelled, all environment data is deleted and any pending statements are charged.

Annual plan. For annual plans, cancellation incurs a 3 month penalty, or the number of months remaining in your annual term, whichever is less.
