Hi @suhelrizvi ,
Few of us here uses community plugin from Logstash or Fluentd to publish the logs via MQTT into Solace PubSub+ using topics. From there, we use topic to queue mapping to persistently store the logs and also most importantly do some routing/filtering as needed.
One sample plugin is here: GitHub - toyokazu/fluent-plugin-mqtt-io: Fluent plugin for MQTT Input/Output. Look at the output part.
