iRule - unexpected behavior
Hello Community, I have recently experienced an unexpected behavior from an iRule, where the http responses were intermittent and failure detected on the last event in the iRule HTTP_RESPONSE_RELEASE. We have noticed the odd behaviour started when the log destination pool members failed to respond to health-check monitor (server down). Below is a snippt of the iRule event where the failure observed. when HTTP_RESPONSE_RELEASE { # figure out the final duration and add it to the IPFIX log set stop [expr {[clock click -milliseconds] - $start}] IPFIX::msg set $rule1_msg1 flowDurationMilliseconds $stop # send the IPFIX log IPFIX::destination send $static::http_rule1_dest $rule1_msg1 } I'm questioning two things: Why the failure was intermittent and havent affeted all responses? Why the pool memebrs status affected the iRule when they went down? I'd appreciate any explanation. Regards, Sarah.
