WM peaks - only half of link shown

[kafooo]

Hi,

for start, we are not using cacti, just pure weathermap, but i believe this is same for both option


We got WM of our network with current traffic and i am trying to make WM with peaks.

I copied map and added only this to map:

SET rrd_start now-1week
SET rrd_period 604800
SET rrd_aggregate_function MAXIMUM

its working fine except i can see peak of only one link - please see attached pic


This is how config of links generally looks:


LINK AMS[Po10]---FRB
INFOURL https://XXX/ams-ar-core-1.txt
OVERLIBGRAPH https://XXX/ams-ar-core-1.png
TARGET /var/home/portax/var/rrd/192_168_200_201_1000010_1min.rrd:ds0:ds1
NODES AMSs:60:0 FRBs:-60:0
BANDWIDTH 100G
WIDTH 8


Any ideas how to show peaks from both direction? Thanks!

What version of rrdtool & weathermap?

What do you see if you use --debug? (look for the ReadData lines - they'll show you what data is being returned)

Also, did you e-mail me about this? I have a half-finished reply to someone asking about similar stuff...

Hello,

weathermap 0.97b
RRDtool 1.6.0

in debug mode i found out that rrdtool is returning only OUT, but dont know why...

Code: Select all

And yes, i wrote you an email about this, but then thought it would be good to post it on forum also, at least others can benefit from solution


I did little more digging and i think that this site - http://network-weathermap.com/articles/096-rrdtool would answer most of my questions, but its not working anymore

I also tried to run mup with following options instead:

Code: Select all

php weathermap --config=/home/portax/weathermap/configs/cdn77_locations_peaks.conf --define rrd_aggregate_function=MAXIMUM --define rrd_period= 604800 --define rrd_start=now-1week

but everytime it returned average instead of MAX

about rrdtool command, i would like to add that if i run exact same command from server itself, its working ok:

Code: Select all

/var/home/kafooo# /usr/bin/rrdtool graph /dev/null -f '' --start now-1week --end start+604800 DEF:in=/var/home/portax/var/rrd/185_59_221_254_1000009_1min.rrd:ds0:AVERAGE VDEF:agg_in=in,MAXIMUM "PRINT:agg_in:'IN %lf'" DEF:out=/var/home/portax/var/rrd/185_59_221_254_1000009_1min.rrd:ds1:AVERAGE VDEF:agg_out=out,MAXIMUM "PRINT:agg_out:'OUT %lf'"
'IN 1901770119.962286'
'OUT 3898077209.642488'

Yes, I think this is an issue with rrdtool 1.5 and 1.6 where the output format changed slightly.

Here's the github issue for it. It's fixed in the dev version. The fix is a one-liner if you want to change your own copy though.

On line 276 of weathermap/lib/datasources/WeatherMapDataSource_rrd.php, just add a # to the beginning of the line to comment it out. It's the line that says "skip the blank line"
