I'm sorry, I'm not quite sure what you mean about trying with plain rrdtool? As far I could tell you can use negative exponent values with rrdtool, it's listed in the docs, and it does work as expected. The only problem was that particular regex was filtering out any negative values thus preventing ...

No, if it doesn't exist at that OID then it doesn't exist. Whether or not there is a way to make it exist is another matter, but that is outside the discussion of polling it with Cacti. Think of OID and MIB roughly as you would DNS and IP addresses, an OID is a numeric listing for a particular MIB. ...

Is it a specific browser it does this on?

Have you looked at this thread?

Umm... this could be anything. Is it happening on all graphs at the same time? If so, check you cacti.log and look for problems.


Adam

This may be a stupid question, but you did add the devices to the tree didn't you?

Have you looked at the command line options? http://docs.cacti.net/?q=node/535 You should be able to customize the host templates to contain anything you need, but you have to work from the ground up. Host templates are made of Graph Templates and Data Queries. Graph templates will reference Data Te...

Well, snmpd is a server side application, so you would have to install it like any other application you might want to run on a server. If you utilize SSH keys, you may be able to rig up a script to install it automatically. But that could be a bit risky, especially if there's much variation between...

Yes, it can definitely do that, but may be a little overkill. If you already have a web server installed with php, mysql, rrdtool and snmp stuff, then it wouldn't be that hard to throw Cacti up and configure this. However if you just wanted bandwidth reports for your one local system you may want to...

For 1 minute polling, shouldn't cron be left to run at 5 minute intervals and the poller to 1 minute? Not sure if that is causing the issues, but maybe something to look into. Also, what is your cacti.log showing as far as poller information goes?

Do you have snmp setup properly? Those look like the default memory and processes graphs which if I recall uses a script as the data input method. The default traffic graphs use snmp to gather their info.

Just for other's sake for future reference, sometimes the auto-padding option can cause issues with column alignment.

I would be interested in something like this as well. I'm not sure about displaying it in the graph though. Seems like that would require more work than say for instance a plug-in that could list some information on the graph page or next to a graph. The poller strips out, for the most part, non-num...

That's the poller debug log. If the data is updating correctly, then polling and data sources aren't the problem. Graph debug is when you go to "Graph Management", select the particular graph you are having problems with, and click "Turn On Graph Debug Mode" up in the upper right...
