analyze and probe the responses from the services to which they are bound only
when those services receive client requests. The inline monitor is of type
HTTP-INLINE and can only be configured to work with HTTP and HTTPS services. An
inline monitor determines that the service to which it is bound is UP by
checking its responses to the requests that are sent to it. When no client
requests are sent to the service, the inline monitor probes the service by
using the configured URL.
Note: Inline monitors
cannot be bound to HTTP or HTTPS Global Server Load Balancing (GSLB) remote or
local services because these services represent virtual servers rather than
actual load balanced Web servers.
Inline monitors have
a time-out value and a retry count when probes fail. You can select any of the
following action types for the NetScaler appliance to take when a failure
After the service is
down, the service remains DOWN for the configured down time. After the DOWN
time elapses, the inline monitor uses the configured URL to probe the service
to see if it is available again. If the probe succeeds, the state of the
service is changed to UP. Traffic is directed to the service, and monitoring
resumes as before.
