aggregate all DS from one rrd

[sh0x]

Hi,is there an easy way to add all of the data sources in the same target together and display the output? For example I want to combine these values and display them as an aggregate.

guage:{map:cacti_path_rra}/node_errors_in_4000.rrd:errors_in
guage:{map:cacti_path_rra}/node_errors_in_4000.rrd::errors_out
guage:{map:cacti_path_rra}/node_errors_in_4000.rrd:discards_in
guage:{map:cacti_path_rra}/node_errors_in_4000.rrd:discards_out

I think I could put that all on one line and it would total them up, but then I'd have to do this for every link. Its a lot of typing, so I'm looking for an easier way.

Thanks!

Code: Select all

LINK DEFAULT
   TARGET gauge:{map:cacti_path_rra}/node_errors_in_{link:this:local_data_id}.rrd:errors_in:- gauge:{map:cacti_path_rra}/node_errors_in_{link:this:local_data_id}.rrd:-:errors_out gauge:{map:cacti_path_rra}/node_errors_in_{link:this:local_data_id}.rrd:discards_in gauge:{map:cacti_path_rra}/node_errors_in_{link:this:local_data_id}.rrd:-:discards_out
   
LINK one
   NODES a b
   SET local_data_id 4000
   
LINK two
   NODES c d
   SET local_data_id 3384

(that's all one line for the target, and I corrected the spelling of gauge, and the ds specs wouldn't have worked without the - in there).

Thanks I see how that works. When I use a "-" I get an error. For example:

Code: Select all

TARGET target_errors_in_4366.rrd:discards_in:-

Results in:

Code: Select all

target: /var/www/html/cacti/rra/target_errors_in_4366.rrd:discards_in:- on config line 80 had no valid data, according to WeatherMapDataSource_rrd 

But if i use:

Code: Select all

target_errors_in_4366.rrd:discards_in:discards_out

I don't get any errors, but thats not what I want. I'm leaving gauage out for now until I understand this part.

Well, actually it is, if you want to show total errors/discards in and total errors/discards out as the two sides of link. You can reduce it to:

Code: Select all

LINK DEFAULT 
   TARGET gauge:{map:cacti_path_rra}/node_errors_in_{link:this:local_data_id}.rrd:errors_in:errors_out gauge:{map:cacti_path_rra}/node_errors_in_{link:this:local_data_id}.rrd:discards_in:discards_out 

If you want the in and out errors to all appear on the 'in' side of the link on the map, then the example I gave was wrong anyway.

The '-' issue is a bug in 0.96 that is fixed in 0.97 - sorry, I'd forgotten about that. It should work again soon though.

Hi,
I'm trying to show the total power used in each of the banks of the PDU's in my racks on weathermap...

To do this i've followed this thread...

What i'm getting displayed is the first DS's value... or a no value at all..
the two ds's are :-
host-1-bank1
host-2-bank1

This is the target line from my config..

TARGET 0.1*gauge:/var/www/html/cacti/rra/host-1-bank1.rrd:APC_32a_Bank1_Load:- 0.1*gauge:/var/www/html/cacti/rra/host-2-bank1.rrd:APC_32a_Bank1_Load
I'm using
weathermap 0.97a
Cacti 0.8.7e

I've tryed removing the space from the ":- 0.1*gauge" bit.. taking out the "-" but it seems to not like it
Can any one help??

Thanks

You are missing the :- from the end of the second part. You should be getting an error in the cacti log saying that the second part is not recognised as a valid target.

So you MUST have the space between the two parts, because they are two separate targets. And if you specify DS names, you MUST specify two DS names, even if the second one is only '-' (which is the bit you have wrong at the moment, I think).

Yea it works now !!

Thanks sorting that out Howie ... it was driving me round the bend :S
