[SOLVED] Use a specific snmp value in a node label

[Howie]

Ah Windows, my old friend. Most likely this is because the way you specify the path doesn't exactly match the way Cacti stores it, so Weathermap can't figure out which DS is related to that rrd file, and so can't use poller_output.

Check in the debug log again, and there's a line from WEATHERMAP that says something like "Your rra_path is ..." make sure your path is specified *exactly* like that.

I don't have any entries for rra_path in the log. Here is some stuff I do see from .95b:

0.95b? One of the changelog entries for 0.96 was:
"FIXED - Cacti poller_output support works more reliably/at all on Windows"

so I'd suggest upgrading. I knew I went through this whole poller_output debugging thing with one user a while ago...

you get 2 years worth of bug fixes and improvements for free, too

[Howie]

Looking further, 0.96 changelog also has the following new features:

"RRD datasource can take SET rrd_default_path to make configs a little easier to read.
RRD datasource can take SET rrd_default_in_ds and rrd_default_out_ds for non-Cacti users.
RRD datasource can get Cacti query information (in poller_output mode ONLY) - like ifAlias, ifSpeed etc
RRD datasource can take the ifSpeed/ifHighSpeed from the above, and use it in the map.
RRD datasource fills in Cacti cacti_path_rra and cacti_url with Cacti base path and URL
RRD datasource can take global SET rrd_options to add extra options to rrdtool command lines"

which would explain why it's not working for you.

WOW! What a difference a few years makes. I like the changes you've made. It's going to take some getting used to all the enhancements.

I am still seeing "UNKNOWN" I even waited for more than 3 polling cycles just to very. Here's the pertinent information in the logs:

I see all the items I think I should be seeing except the fact that I get the "Unknown" in the map Am I missing something?

[Leddy]

Looks like I needed "node" and not link in the LABEL declaration....

LABEL {node:this:cacti_ifSpeed}

DUH!
