# SSL Monitor
> MainWP SSL Monitor Extension allows you to keep an eye on your Child Site(s) SSL Certificates and sends email alerts when monitored certificates are nearing expiration.
## What You'll Learn
* Checking SSL certificate status for HTTPS child sites
* Viewing detailed certificate information
* Scheduling automated SSL checks
* Overwriting general settings for individual sites
***
**Extension Add-on** - This add-on provides standalone functionality within MainWP Dashboard. No third-party plugins required.
The SSL Monitor extension allows you to check information about SSL certificates for your HTTPS child sites. The table on the **Dashboard** page of the SSL Monitor extension gives you insight into the most important information, such as the expiration date, who the issuer is, and the common name.
The extension also provides all the detailed information about the SSL certificates that you may need.
## Install the SSL Monitor extension
Click the **Install Add-ons** button
Once the installation process is complete, click the **Activate Add-ons** button.
## Check SSL Certificates
### For all Sites
### For individual Sites
## View Detailed Certificate Information
## Adjust the SSL Monitor Settings
Go to the **MainWP > Add-ons > Monitoring > SSL Monitor > Settings** page.
1. **Notifications threshold (days):** you will be notified by email if an SSL Certificate for any monitored site reaches the threshold you define here.
2. **Automated Checks:** you can enable automatic SSL certificate checks and set the frequency for those checks
## Adjust the SSL Monitor settings on a Single Site
Locate the Child site, open its Dashboard, and go to **SSL Monitor > Settings** page
1. Overwrite the general settings by enabling the **Overwrite general settings** toggle
2. Adjust the Notifications threshold (days) and whether you want to automatically check SSL certificates for this specific site
## Check Sites via WP CLI
If you prefer running SSL checks from the command line, or want to trigger them from a script or cron job outside of the MainWP Dashboard's built-in scheduler, use the WP-CLI commands the extension registers under `wp mainwp-ssl-monitor`.
Both commands accept either a comma-separated list of child site IDs or the `--all` flag to target every child site.
Check the SSL certificate for one or more sites:
```bash theme={null}
wp mainwp-ssl-monitor check 2
wp mainwp-ssl-monitor check 2,5
```
Check all sites:
```bash theme={null}
wp mainwp-ssl-monitor check --all
```
View saved SSL certificate information for one or more sites without triggering a new check:
```bash theme={null}
wp mainwp-ssl-monitor info 2
wp mainwp-ssl-monitor info 2,5
wp mainwp-ssl-monitor info --all
```
## SSL Monitor REST API
