# Manage Your Cron and Uptime Monitors

All Sentry plans include **one cron monitor** and **one uptime monitor**. To activate additional monitors, you need to add a [**pay-as-you-go (PAYG)**](https://docs.sentry.io/pricing.md#pricing-how-it-works) budget.

The PAYG budget is only available on **paid plans**.

## [Key Terms](https://docs.sentry.io/pricing/quotas/manage-cron-monitors.md#key-terms)

* **Reserved Quota**: The number of monitors included in your plan.
* **Pay-As-You-Go (PAYG) Budget**: A budget you set to pay for additional monitors beyond your reserved quota.
* **Reusable Quota**: Quota freed up by deactivating or deleting monitors within the same billing period, which can be reused for new or reactivated monitors at no additional cost.

## [Viewing and Adjusting Your PAYG Budget](https://docs.sentry.io/pricing/quotas/manage-cron-monitors.md#viewing-and-adjusting-your-payg-budget)

To check or adjust your monthly PAYG budget for cron and uptime monitors:

1. Go to **Organization Settings > Subscription**.
2. Review your current PAYG budget.
3. To change your budget, adjust the amount as needed.

## [Activating or Reactivating Monitors](https://docs.sentry.io/pricing/quotas/manage-cron-monitors.md#activating-or-reactivating-monitors)

When you add a new monitor or reactivate a previously deactivated one, Sentry will attempt to activate it based on your available quota and budget.

**Activation Process:**

1. **Check for Reusable Quota**

   * Sentry first checks if there's any **reusable quota** from monitors of the same type deactivated or deleted within the **same billing period**.
   * If available, the monitor is activated using this quota **at no additional cost**.

2. **Use PAYG Budget or Reserved Quota**

   * If no reusable quota is available, Sentry uses your **reserved quota** or **PAYG budget** to activate the monitor.
   * The cost is deducted from your PAYG budget.

**Important:** Quota reuse only applies **within the same billing period** and to monitors that were previously assigned and billed.

### [Activation Across Billing Periods](https://docs.sentry.io/pricing/quotas/manage-cron-monitors.md#activation-across-billing-periods)

At the start of each new billing period:

* **Quota Reset**: All quotas reset, and any reusable quota from the previous period is no longer available.

* **Re-evaluation of Monitors**:

  * If you have sufficient **reserved quota** or **PAYG budget**, monitors that were previously active will remain active.
  * If there isn't enough budget, monitors may be automatically deactivated.

* **Manual Deactivations or Deletions**: Monitors that were manually deactivated or deleted will remain in that state.

## [Deactivating or Deleting Monitors](https://docs.sentry.io/pricing/quotas/manage-cron-monitors.md#deactivating-or-deleting-monitors)

You can manually deactivate or delete monitors at any time from the **Alerts** page, you can use the **Alert Type:** dropdown to filter for **Cron** or **Uptime** monitors.

**Effects of Deactivation or Deletion:**

* **Quota Becomes Reusable**: The quota from the deactivated or deleted monitor becomes available for reuse **within the same billing period**.
* **Billing Impact**: Deactivated or deleted monitors will **count** towards your billing quota if they were previously active in the current billing period. Otherwise, they don't count towards your billing quota.

- **Quota Reuse Limitations**:

  * Reusable quota is only available **within the same billing period**.
  * Applies only to monitors that were previously active and billed.
  * **Reusable quota does not carry over to new billing periods.**

## [Example Scenario](https://docs.sentry.io/pricing/quotas/manage-cron-monitors.md#example-scenario)

Let's illustrate how this works with an example:

1. **Starting Situation**:

   * You have a reserved quota of **1 monitor**.
   * You have a PAYG budget that allows for **5 monitors**.
   * You currently have **6 active monitors**.

2. **Deactivating or Deleting a Monitor**:

   * You deactivate or delete **Monitor A**.
   * The quota from **Monitor A** becomes **reusable** within the same billing period.

3. **Activating a New Monitor**:

   * You add a new **Monitor B**.
   * Sentry checks for reusable quota and finds it from **Monitor A**.
   * **Monitor B** is activated **at no additional cost**.

4. **End of Billing Period**:

   * All quotas reset.
   * You need to ensure you have enough PAYG budget to cover all active monitors for the new period.
   * You have **6 active monitors** and a **PAYG budget** for **5 monitors**.
   * You have **1 deactivated or deleted monitor**.
   * You only pay for the **PAYG budget** of the additional **5 monitors**.

## [Tips for Managing Your Monitors](https://docs.sentry.io/pricing/quotas/manage-cron-monitors.md#tips-for-managing-your-monitors)

* **Monitor Your Usage**: Regularly check your active monitors and PAYG budget to avoid unexpected deactivations.
* **Adjust Budget as Needed**: If you plan to add more monitors, consider increasing your PAYG budget beforehand.
* **Plan for Renewal**: Remember that quotas reset each billing period. Ensure you have sufficient budget to keep monitors active.

By understanding how monitor activation and billing work, you can effectively manage your cron and uptime monitors and avoid interruptions in your monitoring.
