I''ve got a how-to for nagios+centos here -> http://www.cognitive-dissonance.org/journal/category/nagios/ There are some other tools you may want to look at also, like cacti or smokeping. Of the three, nagios and cacti are the best I feel.

Does anyone have any recommendations for network monitoring systems that work with CentOS 3 or 4? thanks

Rock solid system and very fast. It can be kind of a bear to configure (XML configuration files and testing even simple changes sometimes require you to restart the entire monitoring system which can take a while), but once you get the thing set up right, it just works. It does graphing as well, but I prefer to use Cacti for that. Ray

I use Argus for monitoring and alerting: http://argus.tcp4me.com
Initially I was almost going to write a full essay about how
much and why I like it :) but a pic worths a thousands words.
Just check out the demo, and you''ll get a pretty good ideea
about what it can do. The configuration files are also very
nice and clean, you can break the configuration into several
files, group the options as you see fit, etc.
Here''s a glimpse of how the config files look like,
it can be as simple as:
Host "alex" {
hostname: localhost
Service TCP/SSH
Service TCP/SMTP
Service TCP/POP
Service TCP/IMAP
Service TCP/HTTP
Service UDP/Domain/slack.i
Service UDP/NFS
}
or as complete as you need:
Host "alex" {
note: This is the main monitoring server, located in Oradea, Romania.
details: The system is a PIII @600 MHz box with 256RAM, 2xSCSI disks.
graph: yes
hostname: localhost
Service TCP/SSH
Group "Email" {
Service TCP/SMTP {
label: SMTP
}
Service TCP/POP {
label: POP3
}
Service TCP/IMAP {
label: IMAP
}
}
Service TCP/HTTP
# UDP/DNS sends a ''status-query'', UDP/DNSQ sends an
''IN ANY'' query.
# Some DNS servers (notably djbdns) do not handle
''status'' queries.
# UDP/DNSQ is available only in versions 3.1 and later.
Service UDP/DNSQ {
hostname: 192.168.0.1
}
Service DNSQ/A/slack.i {
hostname: 192.168.0.1
expect: 192.168.0.1
}
Service UDP/NFS
Service Prog {
severity: major
label: Storage
command: /usr/bin/nc localhost filestat
expect: OK
}
Service Prog {
label: MySQL
command: /usr/bin/nc localhost mysql-ping
expect: 2500
}
Service Ping {
uname: alive
}
}
Good luck,
Alex

It can summarize the traffic going by in many useful ways. And ethereal for more specific sniffing. -- Les Mikesell lesmikesell@gmail.com

Argus looks similar and not similar. I may want to try it out. How does it remote monitoring? Only by SNMP or is there an agent application available (short glimpse over the documentation doesn''t reveal one)? I''m not familiar with SNMP at all, so it''s not an option for me.

It doesn''t have SNMP at all but does network probes from a central location and has an optional local agent for additional information. A nice touch is that it has a message throttling mechanism where you can have it notify you about problems but limit both the number of times for any particular notification and the number of total notifications it will send. If the machine doing the probing looses network connectivity for a while it won''t page you thousands of times. -- Les Mikesell lesmikesell@gmail.com
