Frequently Asked Questions
Common questions about LukStack Uptime Monitor
A firewall or security plugin is blocking the monitoring server
The site requires authentication
There are geographic restrictions
Try adding your monitoring server IP to any whitelist or firewall rules.
Will this slow down my WordPress site?
No. The monitoring checks run in the background via WordPress Cron and do not affect your site frontend performance.
Can I monitor non-WordPress sites?
Yes. LukStack Uptime Monitor can monitor any publicly accessible website, regardless of the platform.
How do I set up Slack notifications?
Create an Incoming Webhook in your Slack workspace
Copy the webhook URL
Paste it into LukStack Uptime Monitor > Settings > Webhook URL
Click "Send Test Notification" to verify
Navigate to Integrations > Webhooks
Create a new webhook and copy the URL
Paste it into LukStack Uptime Monitor > Settings > Webhook URL
What does the SSL monitoring do?
LukStack Uptime Monitor checks the SSL certificate of HTTPS sites and tracks the expiration date. You will receive warnings when a certificate is within 30 days of expiring, with critical alerts at 7 days.
Why are automatic checks not running?
WordPress Cron only runs when someone visits your site. If your site has low traffic, checks may be delayed. For reliable monitoring, set up a real server cron job. See the Help page in the plugin for instructions.
Can I monitor localhost or internal sites?
No. For security reasons, localhost (127.0.0.1) and private IP ranges are blocked from monitoring.
Is there a limit to how many sites I can monitor?
There is no hard limit. However, monitoring many sites from a shared hosting environment may cause performance issues. For large-scale monitoring, consider using a VPS or dedicated server.
Does this plugin send any data externally?
The plugin only makes outbound requests to:
The websites you choose to monitor (to check their status)
Your configured webhook URL (to send notifications)
No data is sent to the plugin developer or any third parties.
