I need to enable history on a IP SLA MONITOR in my cisco router...
There seems to be a bunch of options for what to configure...

I just need to know when the last down even was... can anyone help me with this..

when I look at the history there is no history configured...

Second question - is there a way to edit an ip sla monitor that is already configured? It seems the only way to do it is to remove it and add it back.. seems odd.

what do you mean history? You can retirve the information via SNMP? Is that what you mean?
data is not kept indefinitely however you do have access to the aggregated data;

"show ip sla monitor statistics aggregated"

This doesnt work... there is a command show ip sla monitor statistics but this doesnt give me historical info - it gives me current info.

I need to know the last down time.... does that make sense?

What version of IOS are you using? Can you post your ipsla config
IPSLA is highly configurable, when a threshold is met(or not) a snmp trap can be generated,
or syslog messages can be generated. You need to be looking for them via a NMS (could be open source)
or you could parse through the log. Either way you need an end to end solution.

Older IOS uses the following;
show rtr collection-statistics

This provides some good info
show ip sla mon statistics 1 detail   ( 1 is an example, depends on how you set things up, <ip sla mon ?>
