This is a single server or many at different locations. |

If a WAN monitoring is what you are after, along with individual |
| 10 |
server resources, you have many choices. |

Most of the packages monitor ram as well as other resource utilization |
| 16 |
of the servers, firewall, routers and other SNMP devices in your network. |
| 17 |
some experimentation may be warranted to find what your team likes best. |

OH boy. I like JFFNMS very very much. It has a very old version in portage |
| 22 |
(masked) but a very new version out there for Debian and Ubuntu. It |
| 23 |
runs on all nix, if you want to driectly compile and install. |
| 24 |
|
| 25 |
I'll be putting together a new ebuild, as soon as I get it working |
| 26 |
with the latest postgresql. Mysql works out of the box. Postgresql-9 |
| 27 |
has many new and very cool features. |

Personally, I have some large, high risk design work going on. JFFNMS |
| 34 |
and pg9 are the best choices from my research. A whiz like yourself |
| 35 |
could easily look at the old JFFNMS ebuild and create a new one. |
| 36 |
PG-9 (please no flame wars on mysql vs pg9) is very cool and what |
| 37 |
my work is migrating too, once I get some breathing room. |

Craig at jffnms.org is very cool and responsive. He also works closely |
| 40 |
with those that submit patches. Nagios is a large, disorder array that |
| 41 |
had many devs fork off since the project leader (was/is an a_ole) |
| 42 |
is quite difficult to work with. |
| 43 |
|
| 44 |
JFFNMS rules and is very cool for managing cisco and other routers, |
| 45 |
not to mention a myriad of snmp(1,2.3) devices and all types |
| 46 |
of servers. The original guy, Javier, was snapped up by someone |
| 47 |
worth billions, to manage and extend his financial network, but, Craig |
| 48 |
is probably stronger coder, and extraordinarily nice human being. |
| 49 |
It's mostly php. Lots of folks extend JFFNMS, Craig keeps it clean |
| 50 |
and well written and documented code. |
