Displaying different data with links

[rs1]

Hello,

Been searching the forum for an answer but cannot find it. Probably searching the wrong thing!

Trying to display power from UPS to L1(rack) and to PDU. I have the data sources and they are displaying correctly as graphs. However the links are designed for bandwidth. Is there a way to display it for different data and to set a max percentage.

Sorry if there is docs on this, couldn't find it!

No ideas? Did I not ask the question very well?

Hmm, I posted a reply, but it disappeared...

You should look at:

[*] Use "linkstyle oneway" to show only one arrow (power is one direction)

[*] Use "TARGET gauge:myrrdfile.rrd" to stop weathermap from multiplying by 8 when it reads the data

[*] Use BANDWIDTH to specify the maximum current/power in the same units that will be read from the rrd file.

Just tried it but it's displaying 0, cannot find anything in the logs? I have:

LINK node99999-node88888
LINKSTYLE oneway
INFOURL /cacti/graph.php?rra_id=all&local_graph_id=001
OVERLIBGRAPH /cacti/graph_image.php?local_graph_id=001&rra_id=0&graph_nolegend=true&graph_height=100&graph_width=300
TARGET gauge:/var/www/html/cacti/rra/myrrdfile.rrd
NODES node09797 node23424
BANDWIDTH 100

By the way, thank you for all your help so far.

Any ideas?

Run with DEBUG logging for one poller cycle, then check the logs. You'll see a bunch of lines mark WEATHERMAP and also "ReadData" which are the logging from the data-collection part of weathermap. That will show you what is being fetched from the RRD file. My guess is that you need to specify DS names on the end of the target, but you would be getting warnings in the cacti.log for that (even without DEBUG logging).

Can't find anything, a lot of info to sort through and I don't really know what I'm looking for. Is there anything else I could try?

[Howie]

You could guess I suppose... The logs tell you exactly what is going on, though.

You are looking for the lines like

Code: Select all

RRD ReadData: Headings are:
RRD ReadDataFromRealRRD: Returning

All lines have the map name in them, and for ReadData it will have the link/node name too.
