Properties

NameTypeDescription
Public Property HealthyThreshold System.Int32 Gets and sets the property HealthyThreshold.

The number of consecutive health checks successes required before moving the instance to the Healthy state.

Public Property Interval System.Int32 Gets and sets the property Interval.

The approximate interval, in seconds, between health checks of an individual instance.

Public Property Target System.String Gets and sets the property Target.

The instance being checked. The protocol is either TCP, HTTP, HTTPS, or SSL. The range of valid ports is one (1) through 65535.

TCP is the default, specified as a TCP: port pair, for example "TCP:5000". In this case, a health check simply attempts to open a TCP connection to the instance on the specified port. Failure to connect within the configured timeout is considered unhealthy.

SSL is also specified as SSL: port pair, for example, SSL:5000.

For HTTP/HTTPS, you must include a ping path in the string. HTTP is specified as a HTTP:port;/;PathToPing; grouping, for example "HTTP:80/weather/us/wa/seattle". In this case, a HTTP GET request is issued to the instance on the given port and path. Any answer other than "200 OK" within the timeout period is considered unhealthy.

The total length of the HTTP ping target must be 1024 16-bit Unicode characters or less.

Public Property Timeout System.Int32 Gets and sets the property Timeout.

The amount of time, in seconds, during which no response means a failed health check.

This value must be less than the Interval value.

Public Property UnhealthyThreshold System.Int32 Gets and sets the property UnhealthyThreshold.

The number of consecutive health check failures required before moving the instance to the Unhealthy state.
