When used, a Syslog record will be sent to an external APM (or any other Syslog server) for each gateway transaction.
The Syslog record used is a JSON-formatted data object, containing information aggregated from several sources related to the transaction.
The feature requires DataPower FW 7.6+
Value to Customers
- This feature allows customers to easily display gateway information on their APMs or log aggregators such as IBM APM, Splunk or ELK. This isolates the customer from changes to DataPower's log structure and saves the need to parse Syslog records.
- Customers may link from the displayed transaction in their APM to DPOD's transaction details, in order to enhance troubleshooting efforts.
- DPOD customers can use this feature to externalize DPOD information for data warehouse purposes.
- DPOD customers can retain only the summarized transaction details instead of all log records. This will increase history retention time period and minimize storage requirements.

Feature enablement
Perform the following steps to enable this feature
- Install and configure Store plugin.
- Configure each syslog agent.
- Deploy Event Publisher
- Stop and start all system services.
Plugin Configuration
Configure each Store data node (for example: number 2 and 4) as follow:
- cd /app/elasticsearch_nodes/config/MonTier-es-raw-trans-Node-2
- Edit the elasticsearch.yml file
Uncomment the following parameter:
Parameter Values Description events.publisher.plugin.disable false or true enable or disable the plugin
Configure Syslog agent
For each syslog agent in the system perform the following:
- cd /app/flume/syslog_agents/conf/MonTier-SyslogAgent-nn/ (replace nn with the agent number)
- edit the flume_syslog.conf file
- Locate in each agent rows with pattern: MonTier-SyslogAgent-nn.sinks.syslogElasticSinknnn.batchSize = (replace nnn with sink name 1 to 10. Also - replace nn with the agent number)
- Add below each of these rows the line below (substituting nn and nnn as described in step 3 above)
MonTier-SyslogAgent-nn.sinks.syslogElasticSinknnn.serializer.enableLogicalTx = false
