Cacti

Never mind, finally found it.

Thanks for the help. I'll test it this afternoon and let you know how it goes.

I bet your heartbeat is still defined as 600. You may want to use e.g. 90 to avoid any "automatic gap filling" when using 60 sec step size

That sounds like an idea. So, is this a cacti setting? I can't find it! Just need a hint. Thanks

I've been playing with scripts and WMI to gather the raw cpu data from several windows systems. Things are going really well and the graphs are working perfectly, except that I have seen two spikes (like way above 100%) in recent days. The first spike I had no data for. The second spike happened on ...

I haven't narrowed down the code just yet, but I can definitely post differences in the output based on the URL used for the IMG tag. http://localhost/cacti/graph_image.php?local_graph_id=67&rra_id=0&view_type=tree&graph_start=-604800&graph_end=-360 http://localhost/cacti/graph_image...

I'm still working on why these graphs are wrong. But what I did was compare the stock "Weekly (30 Minute Average)" graph to a custom report for the "Last Week" preset. I then grabbed the "command" used to generate the graph. "Weekly (30 Minute Average)" /usr/b...

This is great work. I'm curious though about say the Performance Monitors. For instance, let's say I want to graph the CPU Utilization using the Counters available from: Select * from Win32_PerfRawData_PerfOS_Processor where Name='_Total' Unlike the linux raw counters that have 100 ticks per second ...

I had the same thoughts. I'm already looking at using rrdtool to collect the data and do the math. It will take some time for me to learn how to do that. In the meantime, I'm going to post the rrd file for the system in question if somebody already has a quick script or something to perform the math.

I've made some modifications to my Cacti Installation to try and get this issue figured out. The first and most important modification was to poll every minute. The default graph for the last day on this system seems correct. http://forums.cacti.net/files/graph_imagelastday_442.png So I'm fine with ...

Call me stupid. I think I got it. I wasn't querying on the correct resolution, thus I was getting 360 second intervals. filename = "r0b-tsmp01_traffic_in_78.rrd" rrd_version = "0003" step = 60 last_update = 1223574362 ds[traffic_in].type = "COUNTER" ds[traffic_in].minim...

I apologize for the delay. Let's suppose for a moment that I wish to poll every minute. And let us say that I'm willing to start over from scratch on all graphs. What would be the best course of action? I've investigated altering the Data Template for Interface - Traffic and setting the "Hourly...

I started here.

The cacti.log gives you the necessary information. The output from the script is incorrect. Cacti requries output that is formatted in a particular way. entity:value You per perl script should look more like this: #!/usr/bin/perl -w # ---------------------------------------------------------- print ...

OK, I've narrowed down why my poller.php is not working properly. It isn't poller.php, but rather an issue with the MySQL Server at mignight. OK u:0.00 s:0.00 r:8.10 OK u:0.00 s:0.00 r:8.10 OK u:0.00 s:0.00 r:9.11 OK u:0.00 s:0.00 r:9.11 OK u:0.00 s:0.00 r:9.11 OK u:0.00 s:0.00 r:9.11 10/02/2008 11:...

OK, so the graph isn't "wrong per say", just the way the data is collected and displayed. More detail below: A cursory examination of the data I collected last night (outside of RRDTool) shows some interesting trends. Basically, I am thinking that the 32Bit SNMP Counters are not adequate o...

1) you need to be aware that RRDTOOL averages data over time, which will affect your bandwidth summaries. You can help to alievate this by increasing the amount of data (aka rows) which rrdtool stores. Read up about it on the rrdtool tutorial. There are also guides in the documentation site on how ...
