RE: [php-weathermap] Smokeping RRDs for Node Targets

["Cook, Garry" <Garry.Cook@xxxxxxxxxxxxxx>]

Excellent! That did it. The leading '0' was missing from MAXVALUE, didn't realize it was needed. I did get a syntax error when doing it wrong, like so:

$ sudo php weathermap --config north.conf
north.conf: Unrecognised config on line 70:     MAXVALUE .1

Perhaps the error could be more descriptive for future newbies?

So, no need to multiply the values, although how to do so is useful info, so I'm glad I know that now too.

If you do get around to writing some articles about this type of stuff, that would be great. At first I was going to point my nodes (all routers) at the CPU Utilization from MRTG. However, that's not really useful to us. The latency at each site is important, so the smokeping data makes a lot more sense. I would be interested in learning more about how you do the IP SLA data though.

Awesome work Howie. I've looked at weathermaps in the past, but they always seemed like more work than I had time for. I'm glad that I decided to look into it again and found php-weathermap.

Thanks,
Garry

MAXVALUE *should* allow decimal values... and SCALE should allow decimal
percentages too. You do need to have the leading 0 in both cases,
though. Maybe that's your issue there? I would have expected that you'd
get a syntax error for that line in the config file otherwise though.

        TARGET scale:100:/var/www/html/mrtg/rrdfiles/NorthMPLS/art1a-BAL-MD01.rrd:median:-

(for rrdtool only, but in most recent versions)
or
             TARGET
100*gauge:/var/www/html/mrtg/rrdfiles/NorthMPLS/art1a-BAL-MD01.rrd:median:-
(must be no spaces, only works in 0.96test1, but works for any datasource)

> Anything else obvious I might be missing? I'm happy to RTFM if someone has a link, Google was less than helpful in this area. It turned up a few posts and such, but upon reading them I'm starting to think that php-weathermap won't work with smokeping. Is this the case?

Yes, other people are using it fine, as far as I know. I did try it
briefly before deciding to use Cisco IP SLA instead, for my own
latency/jitter maps.

Maybe I should write up a few use-case type articles for this sort of
thing...
