    I have tried this in the past on v13.x 🙂 and it showed unexpected behaviours. The in-tmm monitoring was brought up and it caused multiple other pools to go down. Later investigation showed that it consumed huge memory as the version was having a bug. So we turned it off and sticked back to external monitor.

     

    Also to note, if once upgrades from v11 to v13, the upgry process by default appends a SSL profile to the monitor. So need to make sure they remove those profiles or add right profile before turning on in-tmm monitoring.

     

    I'm sure with the latest bug fixes, it should be stable, make sure your infra is on that version. Don't start off with the production and later have a face palm 😉

    Hi ErikM,
    On my part, I use In-TMM monitoring on a version v14.x to be able to use Authenticate Name option on Server SSL profile to perform a CN check of the backend server certificates
    No problem for the past 2 years, it's stable and does the job well 🙂
