Keep it up

Features

- Supported types: Ping, TCP Connect, HTTP/HTTPS Download, SNMP (v1/v2c)
- A can perform multiple attempts per execution. All results are logged including duration
- SNMP queries the system group at each interval and supports per-interface monitoring with alerting on status changes
- Downloaded files can automatically be deleted after a successful download or be kept
- Notifications on failure, or when a service goes down or comes back up
- Tasks can be restricted to WiFi connections to avoid unnecessary mobile data usage
- Configurable suspension intervals for battery saving
- Configuration can be exported and imported as JSON
