Operating Systems Linux Red Hat Network becomes slow and return fast only after restart network Post 302895620 by rbatte1 on Tuesday 1st of April 2014 01:17:08 PM

There may be repeated rogue queries that are trying to return vast amounts of data. If the user is disconnected/timed out/gets bored, they may well re-issue. I would consider reading the application logs to check that the queries are indeed going to return suitable data volumes.

This was learned from prolonged painful experience eventually leading to better validation and sanity checking on the application server before the query was executed.

rwho(1) 							   User Commands							   rwho(1)

NAME
rwho - who is logged in on local machines SYNOPSIS
rwho [-a] DESCRIPTION
The rwho command produces output similar to who(1), but for all machines on your network. If no report has been received from a machine for 5 minutes, rwho assumes the machine is down, and does not report users last known to be logged into that machine. If a user has not typed to the system for a minute or more, rwho reports this idle time. If a user has not typed to the system for an hour or more, the user is omitted from the output of rwho unless the -a flag is given. OPTIONS
-a Report all users whether or not they have typed to the system in the past hour. FILES
/var/spool/rwho/whod.* information about other machines ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------------------------------------+ |ATTRIBUTE TYPE ATTRIBUTE VALUE | |Availability SUNWrcmds | +-----------------------------------------------------------+ SEE ALSO
finger(1), ruptime(1), who(1), in.rwhod(1M), attributes(5) NOTES
rwho does not work through gateways. The directory /var/spool/rwho must exist on the host from which rwho is run. This service takes up progressively more network bandwith as the number of hosts on the local net increases. For large networks, the cost becomes prohibitive. The rwho service daemon, in.rwhod(1M), must be enabled for this command to return useful results. SunOS 5.11 6 Nov 2000 rwho(1)
