Varnishncsa missing requests

[Caunter, Stefan]

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?

Hi,

 

We've got a strange behavior with varnishncsa : some requests that we can see in varnishlog are missing in the varnishncsa logs.

 

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
