[SOLVED] WeatherMap BW Check

Post by packet7 »

Hello,

I just finished installing the Plugin Arch and WeatherMap. Everything appears to be working. However, how shoud I check to make sure the BW Load percentages are correct?

As you can see below, my config is pretty basic. I have included a snapshot below to explain what I mean. I guess I am not sure what values the weathermap plug-in is using (e.g. Current, Average, and Maximum).

It's my understanding that the first object listed in the "Target" line should host the Interface. Correct? How does it look? I would like to utilize Bits per sec (e.g. Mbps, Kbps, etc), but I think that's already done. Thanks!

Note: this is for a point-to-point VPN using a Netscreen Tunnel Interface. We have a fractional T3 with a 15 Mbps CIR (no burst).

Not sure I follow - ((current value)/(max value))*100 => percentage :-?

The first object in the NODES line, but yes, it should be the one the rrd is being measured on.

I think you have the DS names the wrong way around in your TARGET line.

Code: Select all

TARGET /srv/cacti/rra/usnyc1nsc1c_ifoutoctets_20.rrd:ifInOctets:ifOutOctets
So some rough calculations: 2M outbound is roughly 14% of the 15M available, so the 11% should be pointing to boston, not nyc. Swapping the DS names over to the correct way around will fix that.

If you want to see actual bandwidth in the arrows, rather than percentages, add a BWLABEL bits line in the LINK section - the colours will still be based on the percentage use, so you still get some indication of how busy it is.

One note though: if your bandwidth is (in+out)<15M, then the percentages will be wrong. There's no real fix for this one...
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!)

Hello Howie,

That appears to have did the trick. Thanks for your help!

Rgds,

John
