SYSLOGC(8) OpenBSD System Manager's Manual SYSLOGC(8)NAMEsyslogc - collect messages from syslog memory buffer
SYNOPSISsyslogc [-Ccfo] [-s reporting_socket] logname
syslogc-q
DESCRIPTIONsyslogc collects messages from the syslogd(8) memory buffer specified by
the logname argument.
For syslogc to work, syslogd(8) must be configured with one or more
memory buffer logs (see syslog.conf(5) for details) and have a reporting
socket location specified on the commandline (using the -s option to
syslogd(8)).
By default, syslogc will query the specified log and return it to
standard output.
The options are as follows:
-C Request that the log buffer be cleared without reading it.
-c Request that the log buffer be cleared once it has been read.
-f Print out the last 10 lines and read from the buffer
continuously. Like the -f option in tail(1).
-o Check whether the specified log has overflowed. If the log has
overflowed, then a message will be printed to stdout(4) and the
exit status will be set to 1.
-q Request a list of available logs. If a log has overflowed an
asterisk (`*') will be appended to its name.
-s reporting_socket
Specify alternate reporting socket location (the default is
/var/run/syslogd.sock).
SEE ALSOsyslog(3), syslog.conf(5), syslogd(8)HISTORY
The syslogc command first appeared in OpenBSD 3.5.
CAVEATS
The buffer space used for writing logs through the socket is limited.
Thus it is possible to lose logs when running in continuous mode. Losses
are reported on standard error.
