From 947c2a97ad51e1936bad7df0e3f768ab15fcbb36 Mon Sep 17 00:00:00 2001 From: Micael Karlberg Date: Wed, 5 Sep 2018 18:53:15 +0200 Subject: [snmp] Improved Audit Trail Log conversion failure If conversion of an Audit Trail Log (ATL) entry failed, this could result in an abort of the entire conversion, not just the one entry. This has now been improved so that the failure now results in a "error message" into the "stream". Furthermore, we now keep track of the number of entries we succeede and fail to convert.
