280 | Usage: $PROGNAME OPTIONS | ||
281 | A nagios plugin that connects to a Sybase database and checks free space. | ||
282 | |||
283 | Mandatory arguments to long options are mandatory for short options too. | ||
284 | -U, --user Username to connect to database. | ||
285 | -P, --pass Password to connect to database. | ||
286 | -S, --dbsvr Database server (as in the interfaces file). | ||
287 | -D, --dbname Database name to check. | ||
288 | --config=FILE Config file (see SECURITY below) | ||
289 | --checktype=TYPE Type of check to run (see TYPEs below) | ||
290 | --explain Explains how we calculated the free space. | ||
291 | -w, --warning Warning threshold, in percent (default 25) | ||
292 | -c, --critical Critical threshold, in percent (default 10) | ||
293 | -t, --timeout Timeout value, in seconds (default 30) | ||
294 | -h, --help This help message | ||
295 | -V, --version Version information ($VERSION) | ||
296 | |||
297 | Examples: | ||
298 | $PROGNAME -U sa -P secret -S bigbox -D orders | ||
299 | $PROGNAME --config=/secure/nagios-sybase.cfg --checktype=CONNECT | ||
300 | |||
301 | TYPEs | ||
302 | There are two types of checks you can run: | ||
303 | --checktype=CONNECT | ||
304 | Checks just the connection to the database. | ||
305 | --checktype=FREESPACE | ||
306 | (Default) Checks both the connection to the database and the free space. | ||
307 | |||
308 | SECURITY - Using a config file | ||
309 | Since a "ps ax" will reveal your database username and password, you can | ||
310 | instead specify them in a config file. Pass the config file with --config. | ||
311 | The format of the file is: | ||
312 | USER value | ||
313 | PASS value | ||
314 | You can also specify a DBSVR and DBNAME in the file. Comments (#) and blank | ||
315 | lines are ignored. Use whitespace to separate argument and value. | ||
