To support up to 25 VUE application servers, it is recommended to reduce logging from one or more servers. It is recommended to create VPS #2 with up to 50GB of disk space for every VUE application server (this is to hold up to 30 days of logs per server). To reduce the amount of disk space required on VPS #2 and reduce the amount of traffic to VPS #2, you can configure one or more servers to filter the types of logs that can be sent to VPS #2.
Each server is initially configured to send all logs with a severity of TRACE (TRACE, DEBUG, INFO, WARN, and ERROR) or higher to VPS #2 (for storage and display through Kibana). To reduce amount of disk space needed on VPS #2 and reduce traffic flow saving CPU processing on VPS #2, you can configure each server to send logs based on severity. This allows you to just send ERROR logs to VPS #2 for each server or any combination of logs from 1 server or another. The types of log filtering available for each server is as follows:
- ERROR – Sends only ERROR logs
- WARN – Sends WARN and ERROR logs
- INFO – Sends INFO, WARN, and ERROR logs
- DEBUG – Sends DEBUG, INFO, WARN, and ERROR logs
- TRACE – Sends all logs regardless of severity level
- Off – Do not send any logs
It is recommended to reduce the logging of servers when there are more than 10 VUE application servers configured on a VUE system. You may see issues even when 10 or less VUE application servers depending on the number of logs being generated. If resources (disk space and CPU processing) are running low on VPS #2, you should reduce logging from each server.
This setting only applies to the logs being sent to VPS #2. This allows you to restrict the actual type of logs generated on a VUE server verses limiting the types of logs forwarded to VPS #2.
