Hello, I am using HAProxy community version from a month, i need to understand logs of HAProxy for the i need your help.
Here is a sample of my logs: Sep 6 17:03:31 localhost haproxy[19389]: Health check for server Netrovert-sites/DS-11-81-R7-CLST-Node2 succeeded, reason: Layer4 check passed, check duration: 0ms, status: 1/2 DOWN. Sep 6 17:03:33 localhost haproxy[19389]: Health check for server Netrovert-sites/DS-11-81-R7-CLST-Node2 succeeded, reason: Layer4 check passed, check duration: 0ms, status: 3/3 UP. Sep 6 17:03:33 localhost haproxy[19389]: Server Netrovert-sites/DS-11-81-R7-CLST-Node2 is UP. 2 active and 0 backup servers online. 0 sessions requeued, 0 total in queue. Here my doubts are, in first line health check is 1/2 DOWN and 2nd line it is 3/3 UP, in both cases Layer4 check passed. How to understand it? what exactly it is checking? what are these 1/2 & 1/3's? Finally, is there any document to understand its logging? -- *Thanks & RegardsRajesh Kolli*
