There may be two targets for that document. One is SNMP wizards who don't
know much about ntpd. The other is NTP wizards who don't know much about
SNMP.

Unfortunately I am neither. I know the intersection of the two, and
some of the basics needed to get SNMP running.<br>

These are decent. Unfortunately proper documentation about SNMP is
not exactly commonplace; early on I had to reverse engineer more
than I'd like by poking the master agent and seeing what it did.<br>

<pre wrap="">I assume I also have to setup a system to collect the data and show status or
email alerts or whatever. What do you call that? I think there are several
packages available. Do they all support NTP? Do they monitor NTP servers
directly with NTP packets?

I... am not sure what you are talking about.<br>
<br>
Rough structure of an SNMP system:<br>
<br>
SNMP daemon (like snmpd): Master agent. Everything routes through
this, and it handles the permissions.<br>
<br>
Sub-agent daemon (ntpsnmpd): responds to commands and data requests
relayed to it by the master.<br>
<br>
Clients: Includes utilities like snmpwalk/get/set, as well as more
sophisticated software. Talks to the master agent to send or
retrieve data, and does something with that data.<br>
<br>
Management Information Base (MIB): Document specifying the structure
and meaning of a subset of the data tree. Usually the client will
have a copy of this so that it knows what to look for.<br>

<pre wrap="">At any rate, I/we need the HOWTO level info for setting up the NTP side and I
need a HOWTO for getting the collection end off the ground.
(In case it's not obvious, I don't mean you have to write them. Links to
existing info is fine.)
--------
In case it's not on your list...
ntpd can monitor other ntp servers. Just put "noselect" on a server line
pointed at the system you want to monitor. Then ntpq -p will give you a line
of info and logging to peerstats and rawstats will get the normal data.
