We are using deployed a pod of Apache Webserver on OCP4. Currently we are facing latency issue in this. When request is triggered from browser to webserver and from webserver to appserver. we saw Webserver hold this request in one of its module. This has been further investigated (through Dynatrace logs) and found there is some delay of request processing from Aggregated Apache hooks calls
to handle (mod_lua) of Apache server. I can't paste logs here due to sensitivity nature. but can demonstrate by an example: -
Web request
(/App_version/request) Elapsed type
Apache
Aggregated Apache hooks calls
+79ms
handler (mod_lua)
+30s
the self execution time is for Aggregated Apache hooks calls
is very less but request movement from hooks call to handle taking almost 30secs.
we are struggling with this issue last one week. it happening only on prodution environment but for non-prod with same config working fine.
Thanks in advance.
