In directory sc8-pr-cvs1:/tmp/cvs-serv7036
Modified Files:
check_overcr.c
Log Message:
markup for translation, move send_buffer assignment to process_args so process_tcp_request can be moved outside the conditional, replace if/esleif with switch, replace #defines with enum

- * Program: Over-CR collector plugin for Nagios
- * License: GPL
- * Copyright (c) 1999 Ethan Galstad (nagios at nagios.org)
- *
- * $Id$
- *
- * Description:
- *
- * Notes:
- * - This plugin requires that Eric Molitors' Over-CR collector daemon
- * be running on any UNIX boxes you want to monitor. Over-CR
- * is available from * http://www.molitor.org/overcr/
- *
- * Modifications:
- *
- * 08-11-999 Jacob Lundqvist <jaclu at grm.se>
- * Load was presented as a one digit percentage - changed to two digit
- * value * before load of 11.2 was presented as "1.2%" (not very
- * high). Warning and Critical params were int's, not very good
- * for load, changed to doubles, so we can trap loadlimits like
- * 1.5. Also added more informative LOAD error messages.
