Log transfer mechanism

[bmm]

Hi, from the webinar I understand that Rsyslog is used to transfer logs between hosts. I had few questions regarding data transfer:
- does it uses TCP transport?
- how does it behave on infiniband/Mellanox infrastructure as against traditional ethernet setup?
- how frequently the logs are transferred across? is it configurable?
- we use log4j that archives our app logs into gz files, does gz files work with nagios log server?

Thanks

does it uses TCP transport?

Yes.

how does it behave on infiniband/Mellanox infrastructure as against traditional ethernet setup?

This is not something we have documented. I would assume as long as traffic can get from point A to point B, it should be fine.

how frequently the logs are transferred across? is it configurable?

Generally instantly. How would you like it configured?

Not out of the box. There's a logstash feature request open that doesn't appear to have happened yet.
