Correct value on Weather Map

[DanielU]

I am trying to present data from cacti graphs on Node on Weather Map.
There are sessions and traffic of pool Big IP F5 traffic balancer.

Fragment of code:

Code: Select all

NODE node_f5_PAC_traffic
	LABEL PAC {node:this:bandwidth_in:%d}MB 
	LABELOUTLINECOLOR none
	INFOURL /cacti/graph.php?rra_id=all&local_graph_id=9287
	NOTES Pool_PAC Traffic
	OVERLIBGRAPH /cacti/graph_image.php?rra_id=0&graph_nolegend=true&graph_height=100&graph_width=300&local_graph_id=9287
	TARGET gauge:/usr/share/cacti/rra/f5_x_pool_traffic_in_9805.rrd:pool_traffic_out:-
	POSITION x 80 -50

NODE node_f5_PAC_sessions
	LABEL PAC {node:this:bandwidth_in:%k}
	LABELOUTLINECOLOR none
	INFOURL /cacti/graph.php?rra_id=all&local_graph_id=9159
	NOTES Pool_PAC Sessions
	OVERLIBGRAPH /cacti/graph_image.php?rra_id=0&graph_nolegend=true&graph_height=100&graph_width=300&local_graph_id=9159
	TARGET gauge:/usr/share/cacti/rra/f5_x_poolconnections_9677.rrd:PoolConnections:-
	POSITION x 80 -30
	MAXVALUE 1000

On screenshots below, you can see value 440186 on first red one,

while the real value on chart is 3,52MB

Traffic

The second value which represent sessions is correct

What is the correct syntax of:

Code: Select all

  LABEL PAC {node:this:bandwidth_in:%d}MB 

????


I had tried few bandwidth_in: possibilities and no results.

So the first value is actual traffic? Don't use gauge:

Normal SNMP traffic counters count bytes. So to get bits/sec both Cacti and Weathermap multiply by 8. In weathermap gauge: tells it to not do that. I think for your case, it DOES need to do that. Classic symptoms: "my value is almost but not quite 10x smaller than I expected to see"

(Some weird devices don't use the normal interface MIB and you have to figure out what is going on. e.g. FC fabrics often count 32-bit words)

Howie,
what a response time

Target guage is incorrect?

Code: Select all

TARGET gauge:/usr/share/cacti/rra/f5_x_poolconnections_9677.rrd:PoolConnections:-

As I wrote my value presented on weather map is 440186 while the real on graph is 3,52MB
The ratio is 125065,69288389513108614232209738

[Howie]

440186 x 8 = 3521488
aka 3.52M

[DanielU]

How can I change type of data or recalculate that to get exact value?
I mean in weathermap conf file.

[Howie]

REMOVE THE GAUGE: PREFIX

[DanielU]

Ok. I have success. Thanks Howie.
Meanwhile I had made some more tries.

Code: Select all

NODE node_f5_PAC
	LABEL PAC {node:this:bandwidth_in:%k}
	LABELOUTLINECOLOR none
	INFOURL /cacti/graph.php?rra_id=all&local_graph_id=9287
	OVERLIBGRAPH /cacti/graph_image.php?rra_id=0&graph_nolegend=true&graph_height=100&graph_width=300&local_graph_id=9287
	TARGET rrd:/usr/share/cacti/rra/f5_x_pop_pool_traffic_in_9805.rrd:pool_traffic_out:-  
	POSITION x 80 -50
	MAXVALUE 20000000

So TARGET rrd:/usr/share/ca.... was the answer.

And..

It is exactly the same value as chart shows.

Howie, you are great!!

[Howie]

You shouldn't need the rrd: either, but you do you.

[DanielU]

I 've tried both and both working

TARGET /usr/share/cacti/rra/f5_pool_traffic_in_9805.rrd:pool_traffic_out:-
and
TARGET rrd:/usr/share/cacti/rra/f5_pool_traffic_in_9805.rrd:pool_traffic_out:-

Thanks

PS Sorry that I seemingly didn't listen you but I couldn't find working syntax.
PPS I wrote once again working examples for admins having the same problems
