Is the BIGIP health check an http check? We stopped using that in favour of a simple tcp check to port 80.
I've looked in my old varnishlog output, we were catching the F5 http health check in vcl_error. Can you send some log examples?

We can clearly see that with Healthchecks from our BIGIP (We've got 4x Varnish behind 2x BIGIP). The BIGIPs are doing 1 request every 5 seconds that we can see in varnishlog. In the varnishncsa logs, we can't see every healthcheck request. Sometime, we have no log at all for 3 or 4 minutes and then the logs reappears. We've done tests with or withour load, and the behavior is the same. Any idea ? Thanks for your help ! Regards, François FANUEL
