# Alerts silences

You may have to mute various alerts in the system. To manage the various resulting "silences", perform these steps:

1. Click the **Alerts** tab, and select **Alert Silences** from the drop-down menu.

2. The **Silences** report appears.

## Using the Silences interface

The **Silences** report has the following information and affordances:

### Silences interface

01. Use **Search** to find a silenced alert by name when you have a long list.

02. Review the list of currently silenced alerts

03. **Status** of the alert.

All alerts in this list should be  (Active).

04. **Matching labels** specify the conditions (rules) that trigger the alert.

05. **Alerts** is the number of issued alerts for this alert rule.

06. **Schedule** of the muting/silence of the alert, start time through end time

07. **Expired Silences** are alerts that were recently silenced, and the silence expired.

08. **Status** of the alert.

All alerts in this list should be  (Expired).

09. **Matching labels** specify the conditions (rules) that triggered the expired alert.

10. **Alerts** is the number of times this alert has been issued.

11. **Schedule** of the silence of the alert, start time through end time.

12. Click  (Add New Silence) to silence another alert; see [Add new silence](https://docs.kloudfuse.com/platform/3.2.5/alerts-silence/#add).

## Add new silence

To create a new silence rule, click  (Add New Silence).

The **Add Silence** interface appears. It has the following information and affordances:

1. Specify **Silence start and end**, the time interval when you plan to silence the alert.

Use the time picker from the drop-down to specify the start of the alert.

2. Specify the **Duration** of the alert.

Note that [Silence start and end](https://docs.kloudfuse.com/platform/3.2.5/alerts-silence/#silence-duration) and [Duration](https://docs.kloudfuse.com/platform/3.2.5/alerts-silence/#silence-duration) changes affect one another.

3. Specify **Matching labels** by creating filters defined by labels and comparison values that match silence conditions. You define these labels in the Alert rules interface, when you create a new alert.

**Label**
   - Enter the name of the label
   - **Operator**
   - `=~`: Regex expression equal
   - `!~`: Regex expression not equal
   - `!=`: Not equal
   - `=`: Equal (default)
   - **Value**
   - Specify the comparison value
   - **Delete**
   - To remove one of the defined filters, click  (Trashcan).

4. To add another filter, click  (Add matcher), and specify another matching label.

5. Click  (Save Silence) to save the silence definition.

6. Under the **Affected Instances** heading, Kloudfuse lists all alerts that were silenced, if they match one or more of the labels. The state of all instances is  (Suppressed).
