|
# a monitor to determine if a PostgreSQL database server is operational |
| 16 |
|
|
# |
| 17 |
|
|
# Rather than use tcp.monitor to ensure that your SQL server is responding |
| 18 |
|
|
# on the proper port, this attempts to connect to and list the databases |
| 19 |
|
|
# on a given database server. |
| 20 |
|
|
# |
| 21 |
|
|
# This monitor requires the perl5 DBI, DBD::mSQL and DBD::mysql modules, |
| 22 |
|
|
# available from CPAN (http://www.cpan.org) |
