Applying data sources to multiple hosts

[assie]

Hi,

Iv got a graph template that needs 2 datasources. It uses a custom data input method (NRPE Disk stats, that parses /proc/diskstats). From that input method, it needs 2 data sources,
reads and writes. OK, so iv got a graph template in place to apply to lots of hosts, but i still need to add the 2 data sources each time. Can this be automated somehow? Iv got too many
hosts that needs em to do it manually.

Thanks in advance,

Assie.

Good news: this can be done.

Hi, i have red the documentation but cound not find what I was looking for. I started to check out the cli scripts and actually found some usefull stuff

php ./add_graphs.php --graph-type=cg --graph-template-id=184 --host-id=235 --graph-title="A HOSTNAME /dev/sda combined count" --input-fields=128:disk=sda

Now for one, i could find the graph-template id using the --list-graph-templates, then find the id of the template. But there is no such option to find the date input template,
I had to go into MySQL and select * from data_template; to get the ID, why cant the script do this too?

second, when I change the title in the previous line from /dev/sda to /dev/sdb and change disk=sda to disk=sdb, it refused to create the graph:

NOTE: Not Adding Graph - this graph already exists - graph-id: (10174) - data-source-id: (12586)

Now one would think with a new title, the script would figure this is another graph and not an existing one... any hints?

Thanks,

Assie.

Can anyone help me out? any info at all?

Thanks..

Then I suppose that I did not understand what you are aiming at. Can you please provide some more words about your goals?

I will use this topic as I have similar problem.

I would like to add graphs for many host as it is described here: http://www.pmacct.net/docs/cacti.html

As you can see there are 2 custom data sources per each graph.

I thought I would use directly the CLI add_graphs.php as there is no add_data_sources.php script.

Based on that description I tried: php -q add_graphs.php --graph-type=cg --host-id=2 --graph-template-id=63 --input-fields="74:aggregation=dst_host 74:adata=192.168.55.55 74:pipe=/var/run/pmacct-in.pipe" --force

This adds only one data source (unnamed), I didn't find any other method for putting 2 datasources there.. I didn't find anywhere any CLI method for creating datasources. Do you know any such examples?

My Cacti version: 0.8.7g

Please post the exported graph template (including dependencies) here. Then I'll try to reproduce.
This then is classified as a cli issue.
In fact, the add_graphs should create ALL related data sources along with the graph. That's why we don't have an add_data_sources script. But add_graphs seems to fail (or there is some different issue here).
In case you prefer a more automated way of creating graphs (and data sources), please see AUTOM8 plugin

Thank you for the quick response I'm having troubles posting the template by the attachment upload ( "The upload was rejected because the uploaded file was identified as a possible attack vector.")

So the link to the file is: http://www.nowatel.com/public/upload/ca ... _graph.xml

One issue is, that both graph and data template require a title. So I unchecked the option in both templates and applied your add_graphs.php command (both numbers for the templates had to be changed, of course). Then, the graph and data source were created.
But I did not understand the graph template really. You defined 3 graph input items, were the data template only provides a single one. How come?
R.

[PSI]

The data template uses 3 custom data inputs (Actual Data (IP number of the monitored host), Aggregation string (src or dst packets) and Pipe file) and upon that 3 custom data inputs we get one output - throughput of the host in one direction (upload or download). So to build the graph template we need to generate 2 Data Sources (one for upload and one for download). To understand what i'm saying you should look at the 3 last paragraphs of the http://www.pmacct.net/docs/cacti.html. I tried to build that graph by cli, but my generated graph is only able to be build with one datasource instead of two (so i get a graph in one direction - upload or download).

[gandalf]

And when creating such a graph manually, all works as expected?

Sorry for the very late reply, but iv been busy on other little projects. For now I solved my cli command line issue by using 2 different graph templates, both being identical but having
different id's in the database, not sure what the other option is/was.

I now have a diff question, but I will make a new post for that.

Thanks!
