hello all,
according to the documents, statsd server collects the following metrics about account-auditor:
Metric Name Description account-auditor.errors Count of audit runs (across all account databases) which caught an Exception. account-auditor.passes Count of individual account databases which passed audit. account-auditor.failures Count of individual account databases which failed audit. account-auditor.timing Timing data for individual account database audits.
and, swift recon middleware provides following information about account-auditor:  account_auditor_pass_completed  account_audits_passed  account_audits_failed  account_audits_since
please somebody help me to understand what is the similarity and what is the difference between the metrics collected by statsd server and metrics provided by swift recon middleware.
Thanks 
Pragya Jain
