- Then i change the way of DAS configuration. Following this blog ,i configured all the api-manager.xml,there is no error and no stats.And store node show info:
[2016-10-18 11:31:39,131] INFO - ReceiverGroup Resending the failed published data... [2016-10-18 11:31:44,134] WARN - AccessConfiguration Error loading properties from file: access-log.properties [2016-10-18 11:31:44,207] INFO - TimeoutHandler This engine will expire all callbacks after : 120 seconds, irrespective of the timeout
- I google the reason ,in wso2 jira,they say this is not a bug.
But I cannot wait for my stats for hours.Did I configure something wrong?
Reguards.
