v2 depending on the type of connection you have to the pool members such as HTTP, HTTPS, RDP, and others, you should be able to use the send string to send a specific command and the receive string to search for a specific response back. The send and receive string are configureable in the health monitor for certain health monitor types but please keep in mind that I believe after 256 lines or possibly a specific data size the F5 will stop process the response so if the text exists beyond that cutoff it will fail the health monitor. If you can provide an example of what you need to test we might be able to come up with the appropriate health monitor to meet your needs.

v2 I don't believe a default SSH health monitor exists but you might try what they did in this article.
