Cacti

Is there a way in cacti to use the timestamp output from a command as the x-axis in the graph? The use case is I have some historical data collected by other application stored in database, and I want to use cacti to show the data. The timestamp in graph seems created by rrdtool, I don't find a way ...

Found the place to set the log level in cacti, run manually again, log says: 07/17/2005 06:03:44 PM - POLLER: Poller[0] DEBUG: About to Spawn a Remote Process [CMD: /usr/bin/php, ARGS: -q /www/htdocs/cacti/cmd.php 0 1] I notice the php I installed is at /www/php/bin/php instead of /usr/bin/php.

Changing the cron job to run as root does not solve the problem. I found only manually run the following commands in sequence could create and update rrd files under rra/ /www/php/bin/php /www/htdocs/cacti/cmd.php this command generates a line in cacti.log about the poller statistics. /www/php/bin/p...

Sorry for the typos, I mean run chown -R cactiuser rra/ log/

Aha, eventually I got the .rrd files when running it as root ! Just like wait for a baby's birth. I think the problem is I set the cron to run as cactiuser and this user may have some issue though I chmod -R cactiuser rra/ log/. Thanks you so much for the help. BTW, what do you mean "set the Lo...

Thanks for your response, man, it's really fast, my surprise! I hope I could contribute to cacti after getting familiar with its arch. BTW, I'm stocked for a couple of days by the "no rra file under /rra dir after install" issue posted in Linux/Unix Specific section, could somebody help me...

Cacti could aggregate numeric data by time, e.g. aggregate 5-min data to 1-hour average. Besides that, is it possible to use cacti to aggregate data from host level to cluster/hostgroup level? e.g. I have the 1-hour average CPU utilization for each host, but my boss wants to see a graph of 1-hour av...

Cacti is a fantastic graphing tool for monitoring I ever see.
But all the sample graphs are time-based (x-axis is time).
Is there a way to create a non-timeseries graph in cacti, e.g.
For last week, what's the overall average CPU utilization by each host (host is the x-axis)?
