What is Health Check?
Health checks are mechanisms that periodically verify the availability of Backend Services. If a health check fails for a Backend Service, requests sent to the vService are not forwarded to the failing Backend Service. This eliminates the need for manual intervention. Once the Backend Service becomes active again (i.e., the health check succeeds), requests to the vService are redirected to the relevant Backend Service as usual. The following health checks can be performed on TR7 ASP:
- TCP
- Ping
- HTTP
- HTTPS
- UDP (DNS)
- FTP
- FTPS
- LDAP
- LDAPS
- Oracle
- Scenario
