SSH Check
Verify SSH server availability, authentication, response and SFTP availability.
What does the SSH check do?
It verifies SSH server availability, security and performance. Tests connection, authentication and response. Important for server administration and secure transfer, especially SFTP.
Why monitor SSH?
SSH is essential for server administration and secure communication. A failure means loss of access or a security risk.
- Ensures uninterrupted remote access.
- Detects performance and availability issues.
- Protects against attacks and unauthorized key changes.
