Send events by syslog is a feature designed to increase performance on the proxy box for statistics purpose.
To use this feature, you need a statistics appliance and Artica v2.11.062812 or above.
By default, the proxy server is in charge to analyze real-time events, compress events and save statistics events to the statistics appliance remote port ( 8086 TCP ).
An Artica service is in charge of analyze real-time events and perform inject statistics to the InfluxDB port.
This method consume some performance :
- The proxy service must write events on local disk.
- An artica process is running to analyze real-time events and compress them.
- When using several proxy servers the InfluxDB port increase it’s resource in order to open a 8086 port for each remote server.
When using the “Send events by syslog” feature, the proxy service sends real-time events directly to the statistics appliance using syslog port ( udp 514 )
This feature shutdown the local Artica service and the remote statistics appliance is in charge to analyze real-time events and inject statistics to the local InfluxDB port.
This way make these benefits:
- No local Artica service is running on the proxy box.
- When using several proxy servers, only one port ( 127.0.0.1:8086).
This reduce resource on the InfluxDB service.
- You are able to see all servers real-time events on the Statistics server trough Artica Web console.
BUT: Sending real-time events consume more bandwidth because events are sent without being compressed
