• Transaction groups are hierarchical
• Levels are equal to relationships (parents and
children):
Level 1: Client request (cache miss)
varnishlog支持丰富的查询语句
• string matching, e.g.: RespProtocol eq "HTTP/1.1"
• regex, e.g.: ReqMethod ~ "GET|POST"
• integer and float matching, e.g.: RespStatus == 200
• boolean operators, e.g.: RespStatus >= 500 and RespStatus
< 600
• parenthesis hierarchy
• negation using not
示例:
varnishlog -g request -i
Begin,Link -d
varnishlog -q 'RespStatus <
500'
varnishlog -g request -q 'ReqURL
eq "/"'
varnishlog -g request -q
'Backend ~ default'
varnishlog -g request -i ReqHeader,RespHeader
