The above is just a snippet! That repeats every five minutes. The size of the log is ever-increasing. "Clear Cacti Log File" under "System Utilities" is supposed to take care of this, but it gives an error when I try:
Clear Cacti Log File Error: Unable to clear log, no write permissions.
It was necessary to log into okra and clear the log by running
sudo -u cacti rm cacti.log sudo -u cacti touch cacti.log
I made a copy, though, just in case. The warnings go back as far as January 2006. Has the issue with jalapeno, etc. been going on that long? 7/4/2007: The data sources that aren't working were disabled (not deleted), so that the log stops filling up with garbage.
Creating a fresh log file exposed some additional functionality in cacti. Now we can view the log file! [2] Apparently the old one was too big. The big benefit of this is that now we can see which host numbers corespond to which machines, among other things, just by clicking the links. For example, host 3 is einstein, and we can see from the log that it's sending invalid responses from one of its hard disk data sources.
