Cacti

Funny you reply to this 3-year old message now, as I've just been updating my stats programs. Here's one for reading how many messages are sitting in the queue: #!/bin/bash # outputs messages in local queue and messages in remote queue if [ "$1" == "local" ]; then /var/qmail/bin/...

Uh.. it's not perl, it's php. And you need to specify names: <path_cacti>/scripts/nettraffic <recvd> <sent> Something like that. Then add output fields (stored in RRA) for "recvd" and "sent" At this point, you should be reading the Cacti documentation, it's all there.

It's written in PHP, which means you need the PHP-CLI binary. Paste it into a file called "nettraffic" or whatever, probably in your cacti scripts directory, but it doesnt really matter as long as cacti can run it, and run "chmod a+x nettraffic". After that, as long as you can ru...

Ah, you used "header (..)" with a space. no wonder my grep didn't find it

I also didn't look closely to see what was used in all files, but top_header sounded reasonable.

Anyway, glad to help out

It might make most sense to use a CDEF to do that, so then you get the flexibility of adding whatever you need. At the same time, this might be hard to implement .. i'm not really sure :p One thing you would want to avoid though is locking users into a specific way of doing things.

with the out-of-the-box install of Cacti, this should be working right off the bat

if it's not, check that perl is installed and working. Make sure you can run

perl <path_cacti>/scripts/loadavg_multi.pl

The name changes after editing input fields Steps to reproduce: 1. Create a new data input, setting name, and input string and output string with one paramter each 2. Click "add" for input, and in the dropdown the name of the parameter you created should be selected. Assign a name, and cli...

Hi Ian, Cacti community I haven't been active here in a while, as I've been extremely busy at a new job and working on a new project (a SCADA system that provides real-world control for water treatment systems). I've chosen rrdtool, and consequently, Cacti, for graphing and trends. (I previously use...

You didn't give very much information, but it sounds like it could be a permissions problem. Whatever user runs cmd.php will be the user it tries to write to your rra files with. If that user doesn't have permission to write, then obviously it won't write. When you say you have no graph, does that m...

It really depends on the method your server uses to store everything for users. Just check the disk space for that directory: du -sb /home/vhosts/username | awk '{print $1 }' Set it up as a shell script that accepts a parameter for username, and then just make a data input for each user using the pa...

I haven't had time to deeply look into this, but upgrading to the 4.3.0 CLI binary (previously was the 4.2.2 CGI binary) seems to break the graphs. Going to my graph output directory, it says it can't open the stream to include the file on line 295 of include/rrd_functions.php. Line 295 is include (...

I actually ended up using ipchains to monitor traffic for each protocol. You can see what I have setup at: http://status.digitalorphans.org/traffic_graphs.php

The scripts I used for this, and a little readme are available at www.djgeespot.com/ipacct-1.0.tar.gz

what's the difference between a signed and unsigned counter? why would a signed counter even be useful? I just assumed all counters were unsigned actually.

I guess maybe if you put min to a -ve number..?

Just a little mistake i just noticed:

On the data source edit page:

Maximum Value: The maximum value of data that is allowed to be collected (number must be smaller than max value).

But the problem lies in the way couters are handled. If you use a COUNTER type, then anytime the value is lower, rrdtool assumes an overflow occured (based on min/max values) and compensates for it. So basically, from what I understand, say you have a max value of 255 (1 byte). You get these data po...
