NAME
uumonitor - Monitors the UUCP system SYNOPSIS
/usr/lib/uucp/uumonitor DESCRIPTION
The uumonitor command displays a synopsis in tabular format of the current UUCP status. The format of each line in the table is as follows: system_name #C #X most_recent_status CNT:# time Table entries are defined as follows: The remote system for which the entry applies. The number of C.files queued for the remote system. The number of requests for remote execution from the remote system. The result of the most recent attempt to connect to the remote system. The number of times that a failure to log in to the remote system has occurred. This does not include the number failed dial attempts. The time of the last status entry was made for this system. The uumonitor command is helpful for detecting systems that have backlogs, that have gone away for awhile, that have changed phone numbers, and so forth. The CNT: field is useful for detecting a system whose login/passwd has changed. If the CNT: field gets larger than the maxi- mum allowable failures (currently 20), no further attempts to connect to this system are made. If the number of C.files queued starts get- ting unusually large (depending on the system anywhere from 100-1000), action should be taken to determine the cause of the backlog. SEE ALSO
