096 - Problem with Target statements

[NetAdmin]

Very strange problem with Target statements, but only in certain nodes. Several other nodes with similar target statements are working fine. All nodes worked fine with Weathermap version 095b.

Cacti log file shows several warnings similar to this:

04/21/2009 09:51:20 AM - WEATHERMAP: Poller[0] WARNING: [Map 13] New York: ReadData: NODE SOMENODE, target: gauge:c:\cacti\rra\routerb_cisco_memused_533.rrd:cisco_memused:- on config line 155 was not recognised as a valid TARGET [WMWARN08]

Code from a working node is:

Code: Select all

Is it failing on all the nodes that have MAXVALUE 64M or is that just coincidental.

[NetAdmin]

Just coincidental. It's also failing on nodes that do not have a maxvalue specified.

Reverted back to 0.95b and all is well with all nodes/maps.

[Howie]

OK - I'll see if I can recreate this one too

Any chance you could PM me the whole config?

[NetAdmin]

Just PM'd you the config. Thanks Howie.

[Howie]

At least part of it is that some of your paths use \ and some use /. It looks like \n is being interpreted as a carriage-return, and therefore the path fails to match the pattern that weathermap expects.

This is why "gauge:c:\cacti\rra\nyc_.." fails but "C:/Cacti/rra/nyc_..." works, I think.

However, that doesn't explain your original example, and it shouldn't do that in the first place.

[Howie]

Here's your fix, I hope.

Change line 743 of Weathermap.class.php from

Code: Select all

$targetstring = $this->ProcessString($target[4], $myobj, FALSE);

to

Code: Select all

$targetstring = $this->ProcessString($target[4], $myobj, FALSE, FALSE);

Please let me know if it completely works for you, but I no longer get the same errors with your map file.

[NetAdmin]

Ah ha! You're exactly right! Any node that contained \n (i.e. c:\cacti\rra\nyc_router......) is absolutely failing in 0.96. I have replaced all of my \ with / and all is well.

Thanks Howie!

It's not a similar problem. The previous one was that the target wasn't recognised at all. Yours is that weathermap thinks rrdtool isn't returning valid data. You can check that:

rrdtool info (your rrd file)

and make sure that the last_value near the top is not NaN.

Then you can use --debug on the weathermap command-line to see what ReadData is getting for that link.

[konsa79]

ok sorry

i think it a path error.... maybe comma value is not accepted

this is my path /opt/zenoss/perf/Devices/SW_Amministrazione/os/interfaces/EtherNet Port on unit 1, port_28

i also try with backslash EtherNet\ Port\ on\ unit\ \1\,\port_28

but nothing change

[Howie]

In here, you are defining SW_CED, but using SW_AMM...

Code: Select all

SET SW_CED /opt/zenoss/perf/Devices/SW_Amministrazione/os/interfaces/EtherNet Port on unit 1, port_28

LINK SW_CED-SW_AMM
        TARGET {map:SW_AMM}/ifInOctets_ifInOctets.rrd:-:ds0 {map:SW_AMM}/ifOutOctets_ifOutOctets.rrd:ds0:-
        NODES SW_CED SW_AMM
        BANDWIDTH 1G

commas shouldn't be a problem with this type of format, but files that don't exist would be

You only just added the backslashes! How could it be a backslash issue before you added them?

When you run with --debug, and use the correct SW_CED, what does ReadData say then?
