I use a quartz job to send some logs to gelf tcp input sometimes. I create some gelf tcp transport to send data, and close them after sending. However I found the active connections have been recovered to zero after closing but the total connection keep accumulating . So what exactly the “total connections” mean? Does it affect the performance if it is too many?
The “total connections” metric is simply the total number of TCP connections that have been established (and possibly have also been closed) over the lifetime of the TCP input. A high number here is no problem (in contrast to a very high number of “active connections” which would hint to clients not properly closing the opened TCP connections).
So if I ensure the gelf transport is closed, I don’t need to doubt about “Total connections” ？
If your clients properly close the TCP connections, there’s nothing to worry about.
