Few tips:
- Perform telnet to the pool member first.
telnet 2.2.2.2:8083
- If the above passes, then make curl test to see whats the data you get,
curl -kv https://2.2.2.2:8083/api/v1/_ping
When you run the above, you should see the string
Initialized
, if you dont see that it means, the backend server is not returning it.
- If you think that server does returns the string
Initialized
but still LTM is not finding it, there is a limititation to it too only if the string is placed after 5,120 bytes into HTTP data. Refer the below article, if this applies in your case.
K3451: Content length limits for HTTP and HTTPS health monitors
Is your ltm pool marking your server as up or down for now ?
- If your ltm pool is marked down, try changing the recv string to
200 OK
alone
