There are some parts of your message that I do not understand very well. I am not clear about the relationship of fluctuation between servers and the introduction of syslog. But it is clear that you are looking for a way to have the router hold syslog messages in some buffer if they can not be delivered to the syslog server. The IOS router can not hold syslog messages in a buffer and deliver them later. For one thing since syslog messages are sent using UDP, there is no way for the router to know whether the syslog message that it sent was delivered to the syslog server or not.
If you are concerned about the possibility of missing syslog messages, then the usual solution for that is to provision 2 syslog servers and to send syslog messages to both servers. If you choose the servers well, then the odds are that they will not both be unavailable at the same time.
The generation of syslog messages does take a small amount of CPU but it is generally not enough to cause problems.
the issues is we are getting the complaint that the servers are getting disconnected from the network and causes the issue to the application server so to track this we introduce the syslog server to capture the link status of the all port
is there any way to send the log for the user authenticated and logged into the routers
ok that explains the relationship between syslog and the server problems. It could be very helpful to see messages from switches and routers when problems are reported from the servers.
Yes there is now a way to send a syslog message when someone logs in to the router. The command is login on-success and it will generate a syslog message when someone logs in to the router. there is also a login on-failure if you wanted to see unsuccessful attempts to login.
