Cacti

Why do you think using free is better than reading the info from /proc? free just reads and parses the information in /proc the same way vmstat, top, and ps do.

I tested it just now, and it isn't working for me on 0.8.3a, but it does work on 0.8.3...

cool this exactly what I needed.

Thanks!

Since upgrading to 8.x, I haven't figured out anyway to do a lot of the CDEF funtions I used to. For instance, I need to display the average user utilization, kernel utilization, and wait percentage across 4 cpus (I poll them seperately). With 6.x I just made a CDEF for each graph with the specific ...

Most often the problem is related to permissions of the user running your cmd.php. That user needs to be able to write to the <cacti_path>/log directory and the <cacti_path>/rra directory.

Also make sure that your crontab is actually running.

You can, but its difficult. I started, but decided it really wasn't worth it... Here's how I think you would approach this: 1) Add the hosts you like to poll, and create their datasources, but lease the disabled, so that cacti won't try to create the RRD yet. 2) If you're using MRTG 1.x (logfiles in...

It should prevent the cmd.php from picking it up when it grabs datasources to poll for. I've tried it, and it seemed to work for me.

Good news. Its pretty easy. Just create a datasource in cacti for each datasource in your RRD. Make sure that the rrd datasource names and paths are correct. If your RRAs are different from cacti's default RRAs, you'll need to add these also. If you don't know whats in you RRDs, then use "rrdto...

I agree that data should be gathered only once. How about using a netsaint/nagios plugin to check the RRDs that cacti creates. If you're interested, I'll finish it up while I'm on vacation :D If your netsaint/nagios installation is on a different server from cacti, you'll have to either use netsaint...

Something cool about this is that you can collect data from any of the windows performance counters. Just check out the nsclient docs for command details.

here's the nsclient page: http://nsclient.ready2run.nl/

There's currently no way to change the default but there is a nifty script to change a graph from bits to bytes here: http://www.raxnet.net/board/viewtopic.php?t=444&highlight=perl+bits+bytes Use the "stack" graph type. If you want to gprint the total use a CDEF to add all of them toge...

Not very difficult actually. Just setup each of you datasources in your RRD in cacti using the datasource configuration page, then configure all of your graphs for each of those devices in the graphs configuration page, then create you graph hierarchy. and do that 2700 times. ouch! or use my cacti_i...

I did some searching, and couldn't come up with the exact MIB you need for this device (a MIB is an explanation of all the monitorable SNMP items). It seems that stats for this device are scattered across multiple MIBs. So you can do one of a few things. If the code that you linked to can return the...

I don't know what webserver you're running, but you need to include "index.php" in the allowed directory index. On apache just add the following to your httpd.conf <IfModule mod_dir.c> DirectoryInex index.html index.php </IfModule> sorry, fixed my typo, so no one else gets confused You pro...

Here's a breakdown of the MIB for car config/stats

I'm not sure which stats you're looking for in particular.
