Incorrect values when graphing F5 Connections in Weathermap

Post by catvipme »

I have noticed for a long time that when I graph F5 - VS - Client Connections in Weathermap my values are totally not the same as what Cacti reporting on the graph.
I'm not sure is the problem with the way I "plot" the Client Connections on the map or is it a bug? I use Weathermap 0.97c


Here is Graph debug:

/usr/bin/rrdtool graph - \
--imgformat=PNG \
--start=1408611993 \
--end=1408698393 \
--title='F5 - VS - Client Connections - /Common/VS_sss' \
--rigid \
--base=1000 \
--height=120 \
--width=500 \
--alt-autoscale-max \
--lower-limit='0' \
COMMENT:"From 2014/08/21 17\:06\:33 To 2014/08/22 17\:06\:33\c" \
COMMENT:" \n" \
--vertical-label='connections' \
--slope-mode \
--font TITLE:10: \
--font AXIS:7: \
--font LEGEND:8: \
--font UNIT:7: \
DEF:a='/var/www/html/cacti/rra/336/8585.rrd':'VsCurConns':AVERAGE \
AREA:a#6DC8FEFF:'Connections' \
GPRINT:a:LAST:'Last\:%8.2lf %s' \
GPRINT:a:AVERAGE:'Avg\:%8.2lf %s' \
GPRINT:a:MAX:'Max\:%8.2lf %s\n'



Here is Weathermap Config for connections node:\

NODE cwww
LABEL {node:this:bandwidth_in:%.1f} Responses/sec
INFOURL /cacti/graph.php?rra_id=all&local_graph_id=6906
OVERLIBGRAPH /cacti/graph_image.php?rra_id=0&graph_nolegend=true&graph_height=100&graph_width=300&local_graph_id=6906
TARGET gauge:/var/www/html/cacti/rra/336/8585.rrd:VsCurConns:-
POSITION lclients 3 21
MAXVALUE 1


Could you give an example what the weathermap config for that node should look like if I make something wrong?
Thank you in advance for your input.

That's strange... what does the first section of
'rrdtool info' look like for that file?
Weathermap 0.98a is out! & QuickTree 1.0. Superlinks is over there now (and built-in to Cacti 1.x).
Some Other Cacti tweaks, including strip-graphs, icons and snmp/netflow stuff.
(Let me know if you have UK DevOps or Network Ops opportunities, too!)

And sometimes it shows a very large number in the map as the following picture does. I really have no idea how and where it gets that large number. Thanks very much for your attention.

OK, first of all it looks like it is not conns/sec, but total current connections, but other than that I don't see a reason for the numbers you are seeing. I'll play a bit more today.
