New Threshold monitoring plugin for 8.5a - sends emails ...
Simple threshold / alarm / event monitoring tool that sends emails & syslog events when configured value is reached. Only sends emails when threshold is reached and then descended (not each time it is polled). Emails include link to associated graph.
Curently only works with gauge-based RRDs (i.e. cpu usage, mem usage, load average, etc) and not counter-based RRDs (i.e. bandwidth / errors, etc).
The way it works is by reading the values out of the cacti.log which is created by the cmd.php output, and then comparing them against configured thresholds from the database. (lame, I know)
Download thold.zip and unzip into cacti root directory. Should create ./thold/ directory. There is a readme me there (with very little info). Run the install.sh script.
This also includes the cactistoric from Droopy - posted earlier in the message boards.
I think it is mostly self-explanitory, but feel free to ask questions. It may require you run the crontab as root. This will only work with *NIX-based systems
I hope to have a 8.6 version soon.

I did not try your solution yet but I think one thing is missing here. The e-mail is send as soon as a value jumps above some threshold. This may lead to e-mail bombing when the value starts oscilating around the defined threshold. To overcome this you can have configurable time during which measured value is greater than a threshold. For example: if the CPU is over 90% for the last 15 minutes then make the trigger the threshold and send a mail. The same approach should be applied before before triggering the threshold down.
And one more thing that can be added is a threshold condition. As far as I understand you just check if the value is greater. Sometimes however it would be nice to know if the value became "less than" or "equal to".
Besides of this this would be great addition to Cacti. You have done a good start!

I have a new version with coming out with a 'trigger' option that allows you to only send an email after 'X' times of reaching the threshold. I hope to post this in a few days. It will also give you the option to turn syslog logging on/off.
I am still working on 8.6 compatability - I have been busy working on some other projects - but I hope to have this released soon. I am trying to use a more intelligent mechanism to extract the data (currently it just greps a log file). This will make it more scalable and compatable with more elements...

These are only updated files - must be installed over version 1.0
New feature - trigger - allows you to specify the number of times the threshold is reached consistently before sending an email
Bug-fixes - email address didn't seem to be getting saved
