Hi, The way forward to go on log monitoring is with Log Analytics solution that we are working on. Anyhow the old logging publishing method is broken and cannot be used with latest carbon release products, because that's tightly coupled with cassandra, Hadoop, etc, and hence we can't use that with current DAS. Anyhow once the LA solution/log publisher (based on log stash publisher) is available, it can be used with existing WSO2 products also.
Thanks, Sinthuja.
