Miharu

Miharu watches over your website and server on your behalf to ensure they're not "down" and that "certificates and domains aren't about to expire." If any abnormalities are detected, you'll receive notifications immediately, preventing the situation of "it's too late by the time you notice."

There are 2 types of monitoring available.

Type 1: Mimawari (Regular URL Checks)

Regularly accesses the specified URL and can detect abnormalities such as:

• Site uptime (downtime detection: HTTP status / timeout)
• Response time recording and delay detection
• Keyword checking in page content (monitoring whether specified strings are included or not included)
• Early warning when SSL certificate expiration is approaching
• Advance warning of domain expiration
• Support for URLs with BASIC authentication
• Check intervals can be selected from 1 to 60 minutes

Type 2: Otayori (Heartbeat Reception)

A method where the server sends a POST to a dedicated URL. You can monitor processes that "should be running" such as cron jobs and batch processes.

• If a POST doesn't arrive within the expected interval, it's notified as "not received"
• If metrics included in the sent data (CPU usage, memory usage, etc.) exceed thresholds set by the user, you'll be notified

Notification Destinations

Notifications are supported via Slack / Discord / Webhook / ntfy / Email. You can select multiple notification destinations for each monitoring.

※ Email notifications are premium-only. Due to sending costs, activation is handled on a case-by-case basis (please use notifications other than email during the free trial).

Monitoring Suppression

You can specify times and dates when you want to stop monitoring in advance, such as "stop monitoring from midnight to 3 AM daily because batch processing is running" or "stop monitoring from 2 PM to 4 PM tomorrow because the server will be down." This prevents unnecessary alerts during times when downtime is expected.

• Hourly suppression: Specify time periods (one-time only / daily / repeating on specific days of the week or dates. Also supports time periods that span across days)
• Daily suppression: Specify "no monitoring on this date." Can be saved as a monitoring suppression calendar and supports Japanese holidays

Public Status Page

You can share the monitoring status with your team or customers via a dedicated URL. Each monitoring's current status, uptime, and recent uptime bar are displayed. Only the name, status, and uptime are made public; URL, authentication information, notification destinations, thresholds, and other settings are never exposed.
