Cacti

I'm planning to retire my current Cacti server, but it's got dozens of graphs and a year of data. I'd like to migrate it all to a new box. Does anyone have any hints to share? I know I've got to: 1. Install Cacti and its dependencies on the new server (running Ubuntu). 2. Copy the scripts and rra di...

I got the same thing moving from 'f' to 'g'. loging was set to debug, but no logs were created. I copied the old poller.php and that fixed it. I'm not in a position to work on debugging it. I've got to demo Cacti to my new boss soon, and don't want to have to explain any more gaps. (Yes, I'm being a...

Howdy, I'm trying to graph some weather info from the National Weather Service using a script and data & graph templates I made (I'll post it all when it's working). The problem is that only one of the data fields is getting added to the rrd file. This is how the RRD was created by Cacti: /usr/l...

I've made a couple small modifications to the script to handle a couple anomolies in the Weather Undergound data. # If there is no windchill, set it to the same as temperature if ($arrayref->[0]->{windchill_fahrenheit} == '') { $arrayref->[0]->{windchill_fahrenheit} = $arrayref->[0]->{temperature_fa...

This might actually be a feature request. We do a fair bit of various kinds of clustering. Many hosts have identical sets of 20+ graphs, that I have to recreate for each one. It would be nice to be able to copy a host, and then just go in and change its name/IP/.... The ability to export hosts would...

I've never liked that graph much, myself. As best as I can tell The graph doesn't show used memory, only free memory. Orange is disk cache and buffers (memory that is available if necessary). Red is truly free unused memory (Linux always keeps this at a minimum). White at the top of the graph is use...

Cheburator: Thanks. I didn't see the exact numbers option.

TheWitness: Huh? I haven't the slightest idea what your are trying to tell me.

How can I add a text string to a graph template? One that can be set when a new graph is created?

Thanks.

I've made a data and graph template for plotting the number of rows in a MySQL database table. The data has a custom data field for the table name. I'd like to have that table name appear in the graph, but don't know how to do that. I'd settle for giving the user an opertunity to add a comment, but ...

I'm having trouble adding a some new graphs to Cacti 8.6c on Linux -- Ethernet and MySQL stats in particular. Here's some info on the MySQL problem: The data is colleted by a PHP script from thest Forums. The rrd file is created at the first update, but all values are "nan". It does not ge...

I've installed the above templates, but am getting only a solid line at zero on my graphs. All data is zero. However, The data is being read correctly from the firewall. Here's a line from my cacti.log: 04/22/2005 12:25:23 PM - CMDPHP: Poller[0] Host[41] SNMP: v2: 10.1.1.1, dsname: fwPktAcceptedIn, ...

Rony, Do you really want my whole Cacti database? it 120kb compressed. I've gone through the process of copying the rrd files onto my recreated device, and it's all working smoothly. Thanks for the help! Rich P.S. It sounds lame, but I'll ask my boss before I can release the database. It's got propr...

I've taken a look at the rrdtool commands that generates the missing graphs and found things like: /usr/local/rrdtool/bin/rrdtool graph - \ > --imgformat=PNG \ > --start=1114006386 \ > --end=1114006196 \ .... Note that the start time is greater than the end time. Does any one know where/how these nu...

I've already done the restore, and it pretty much worked. I really can't afford to loose the historical data. The data is there. I need to figure out what how those to restore those particular graphs to the web page. Your idea of recreating the device (and all 20 graphs) sounds tedious, but likely t...

I'm no expert, so take my reply with a grain of salt, but I don't think it would be easy to do. Cacti is really just a front end to rrdtool. Cacti provides polling and a web interface to rrdtool, but rrdtool provides the data and graph generation.

All, I accidentally deleted a device through the web interface (Yes, I'm stupid!). Fortunately I didn't delete the rrd files. I also had a MySQL dump file from the night before (I guess I'm not THAT stupid!). By doing diffs with dumps from the current Cacti database, I mostly restored the device. I ...
