Cirrocumulushttps health monitor configured with only send strings but no receive strings - what it will check ?
Hi Team ,
If we have https health monitor configured with only send strings but no receive strings in it , what checks does it perform .
can you please explain with below configuration as an example .
Pool Member : 10.10.10.10 : 443
https Monitor
Send string : GET /health\r\n
Receive string : ( not configured )
Per F5 documentation:
"Content check monitors are designed to determine whether a service is available and whether the server is serving the appropriate content."
Also in the same article, "You can also use the default null Receive String value [""] [in a content check monitor]. In this case, any content retrieved is considered a match." (Emphasis mine.)
In other words, without a receive string, a content check monitor satisfies only its first purpose - "to determine whether a service is available." To satisfy the second purpose of a content check monitor - "to determine if the server is serving the appropriate content" - you must include a Receive String with the appropriate content. This is by design, as F5 cannot possibly know what constitutes appropriate content for your application. We provide the monitor shell; you customize it for your application delivery needs.
