Hi Again Everyone! I'm having a strange issue that I'm not quite sure how to troubleshoot. About 2% of my requests are failing.
Each time a request fails it increments the count in traffic_logstats under URL Schemes for "none" or "other" URL Schemes Count Percent Bytes Percent ------------------------------------------------------------------------------ HTTP (port 80) 7 0.01% 4.22KB 0.00% HTTPS (port 443) 121,831 98.05% 1.23GB 100.00% none 1,102 0.89% 0.00KB 0.00% other 1,316 1.06% 0.00KB 0.00% Also in traffic_logstats, it shows something... odd: Origin Server Hits Misses Errors ------------------------------------------------------------------------------ originserver.example.com 0 121,854 0 dnsnamethatpointstoATS.example.com 0 7 1,316 ============================================================================== I have the following rules in remap.config: #redirect to HTTPS redirect http://dnsnamethatpointstoATS.example.com https://dnsnamethatpointstoATS.example.com #remap rules to origin server map https://dnsnamethatpointstoATS.example.com/SomeApplication https://originserver.example.com/SomeApplication reverse_map https://originserver.example.com/SomeApplication https://dnsnamethatpointstoATS.example.com/SomeApplication map https://dnsnamethatpointstoATS.example.com/ https://originserver.example.com/ reverse_map https://originserver.example.com/ https://dnsnamethatpointstoATS.example.com/ The number of errors at the beginning of the logstats output correlates to the count of "other" errors with missing URL schema. I'm not sure why some requests would be using "dnsnamethatpointstoATS.example.com" as the origin server, let alone with a Scheme of "other". I get two types of errors in squid.blog when this happens: 1447283397.297 86400734 <ip address> ERROR_UNKNOWN(90)/000 0 GET dnsnamethatpointstoATS.example.com/SomeApplication/stuff - EMPTY/- - 1447283401.484 86400288 <ip address> ERROR_UNKNOWN(90)/000 0 - / - EMPTY/- - Requests that appear to be successful look like this in the squid.blog: 1447283475.486 96 <ip address> TCP_MISS/200 1178 GET https://originserver.example.com/SomeApplication/stuff - DIRECT/originserver.example.com application/json I can't help but think I've done something incredibly wrong or dumb in my remap.config. Has anyone seen anything like this before? I'm not quite sure what to do next for troubleshooting, as I'm super-green to ATS. Anyone have any ideas or suggestions on what I should look at next, or focus my efforts on investigating? Eric Duesterhaus
