Application Checks
The Application Health Check page in Varsuite Core provides real-time insight into the underlying performance and system metrics of your site installation.
What the Health Check Monitors
Varsuite Core checks several key metrics that reflect the health and responsiveness of your site’s infrastructure. Each metric is colour-coded to highlight status at a glance:
Green – Healthy
Amber – Warning
Red – Critical or unavailable
Monitored Metrics:
Database Response Time
Time taken to query the WordPress database.
Database Disk Usage
How much space the database is currently using.
Debug Mode Status
Checks if WP_DEBUG is still enabled—should be off in production.
CPU Usage
Tracks how much server processing power is in use.
Disk Usage
Total server storage used vs available.
Memory Usage
RAM consumption of the server or container running the site.
Example: If you see
94.62% Used (16.45TB/17.39TB)in Disk Usage, that’s a strong signal you’re nearing capacity and should act quickly.
Interpreting Alerts
If the top of the page displays:
“1 application health check has failed”
At least one key metric has fallen outside safe thresholds. Review the values shown and take appropriate action—such as freeing up disk space, disabling debug mode or upgrading hosting resources.
Use Cases
Troubleshooting sluggish sites
Auditing resource usage before updates or migrations
Identifying limitations in shared hosting environments
Ensuring production settings (e.g. debug mode) are secure
Important Note on Shared Hosting Limitations
While Varsuite Core is fully compatible with shared VPS and dedicated hosting, some application health metrics may be missing or inaccurate on shared hosting. Here's why:
Restricted Server Access
Shared hosting providers often block key PHP functions (exec, proc_open, shell_exec) for security. Without these, Varsuite Core can’t read server level data such as memory usage or real CPU load.
Aggregated Reporting
Resources like CPU and RAM are pooled across hundreds of websites on the same server. This means:
You may see misleadingly high or low values.
Disk and memory reporting may reflect the container, not your specific site.
Missing Data Example
If a health check says:
“Memory usage: Data unavailable”
…it’s likely that your host is blocking Varsuite from accessing this information.
What Still Works on Shared Hosting?
Despite the limitations, you’ll still benefit from:
Database and disk usage stats
Debug mode checks
Uptime monitoring
Plugin/theme version control
Backups and alerting
Scheduled task monitoring
For full metrics and unrestricted access, we recommend using a VPS or dedicated/cloud server for production websites.
Create Alerts
Pair Health Checks with Alert Rules (found under Monitoring > Alert Rules) to get notified when:
Debug mode is accidentally left on
CPU or disk usage exceeds your threshold
Application response time increases
Best Practices
Regularly review this page after major changes
Set alert thresholds appropriate to your hosting type
Use alongside uptime and scheduled task monitoring for full-site visibility
The Application Health Check page turns your dashboard into a live diagnostics hub giving you the tools to catch problems early, tune performance and deliver more reliable WordPress experiences to your clients, no matter where they’re hosted.
