Cool zoom/history feature for cacti :)

fmangeant · Post by **fmangeant** » Tue Dec 16, 2003 3:34 am

I tried to zoom on daily graphes, with the following RRA :

X-Files Factor = 0.5
Steps = 1
Rows = 51840
Timespan = 86400

to keep 6 months of 5 minutes average.

I've also tried with the "original" daily RRA (600 rows) with no luck.

On another server w/ cacti 0.8.4 and cactistoric 0.8.4-0.0.1 I can zoom (on daily graph) on a 1 hour interval of time.

As you can see on the attachement, I can zoom on 1 hour. Note the generated timestamp.
Can you give me a real life start/end example which results in an error ?

For some reason, I was under the impression that the zoom feature would be
part of the graph itself, ala nmis style. http://www.sins.com.au/nmis/

Any plans to add this later? It really is a cool feature

Anyway, cactihistoric is a great addon to cacti.

Can we re-visit this issue, I'm still having problems displaying graphs.

I still get the error bellow everytime I try to gereraate a graph with dates older than 10 to 12 days.

Code: Select all

ERROR: start (1072087291) should be less than end (1070277480)

I can get a graph for an hour time frame only for the current day.

If anyone is having the same issue please let me know. Maybe there is an easy fix to this.

This is the formula I use in excel to convert unix time to a readable format:

Code: Select all

=((A1+((365*70+19)*86400))/86400)-0.41667

Make sure you format the field as MM/DD/YY HH:MM:SS

Thanks in advance,

Diego Vargas

Does the timestamps returned in error matchs the start and end date you entered in cactistoric form ? Can you post the values ?
How many rows did you configured in cacti for the daily rra ?
Does you'r rra files have the same rows number than configured in cacti ?
You can also use this command to convert timestamp to readable date :

Code: Select all

date -d "00:00:PUT_TIMESTAMP_HERE 1970-01-01 UTC"

Hi Bruno

here's a example of errors I get :
- I try to zoom from Dec 23, 11h00 to Dec 23, 13h00 on a daily graph
- this result in

Code: Select all

ERROR: start (1072680424) should be less than end (1072180800)

- the timestamp for the start doesn't match the one I choose :

Code: Select all

$ date -d "00:00:1072680424 1970-01-01 UTC"          (start)
Mon Dec 29 07:47:04 CET 2003
$ date -d "00:00:1072180800 1970-01-01 UTC"          (end)
Tue Dec 23 13:00:00 CET 2003

- this daily RRA has 51840 rows, so does the .rrd :

Code: Select all

$ rrdtool info file.rrd | grep -B 1 rows
rra[0].cf = "AVERAGE"
rra[0].rows = 700
--
rra[1].cf = "AVERAGE"
rra[1].rows = 775
--
rra[2].cf = "AVERAGE"
rra[2].rows = 51840
--
rra[3].cf = "AVERAGE"
rra[3].rows = 797
--
rra[4].cf = "MAX"
rra[4].rows = 700
--
rra[5].cf = "MAX"
rra[5].rows = 775
--
rra[6].cf = "MAX"
rra[6].rows = 51840
--
rra[7].cf = "MAX"
rra[7].rows = 797

Thanks for your help.

It's seems I have problems with rrdtool which calculate wrong start timestamp. I'm looking for help from rrdtool users mailing list.

Bruno Prigent · Post by **Bruno Prigent** » Tue Dec 30, 2003 6:38 am

I should RTFM

The start parameter in rrdtool is relative to current time. I think have corrected the problem in the new release available at http://linkdown.org/download/cactistori ... .04.tar.gz

Thanks Bruno.

There seems to be a problem with the cactistoric.php file (contained in the cactistoric.tar.gz archive) :

Code: Select all

$ file cactistoric.php
cactistoric.php: gzip compressed data, from Unix
$ gunzip cactistoric.php
$ file cactistoric.php
cactistoric.php: POSIX tar archive
$ tar tvf cactistoric.php
-rw-r--r-- cacti/cacti    4455 2003-12-06 15:20:06 graph.php

lib/

lib/rrd.php
../cactistoric.tar.gz
tar: ../cactistoric.tar.gz: Member name contains `..'
tar: Error exit delayed from previous errors

I had to use :

Code: Select all

$ tar zxvfP cactistoric.php
graph.php
graph_image.php
include/
include/config_arrays.php
lib/
lib/functions.php
lib/rrd.php
../cactistoric.tar.gz

to extract the cactistoric.php file (with GNU tar 1.13.25).

Anyway, zooming on 1 hour works now

Cheers,

Frédéric Mangeant

I may have typed a wrong command. May be the consequence of my week end abuses

The archive has been updated.

Thanks you Frederic

Hi,
Finally I set up my new linux box. RH7.3 cacti and cactistoric 8.4 (last versions)
But, my problem still exists:
My graph turns 30 min average value every 1 of 5 poll. I mean, every 30 min. my graph changed.
I want to shoe you this problem in attachment. I wait new cactistoric but nothing change about this problem. Have you any study about it?
My rows =17280

Hi,

I already noticed this problem on a previous cacti box (cacti 0.6.8 and Redhat 7.3). I think this problem also appears when using the graph_view.php page, so the problem may be comes from rrdtool.
Since I moved to a Debian machine with cacti 0.8.4, this problems doesn't exists (for the moment).

If somebody have this problem or more informations, report ...

Bruno

RH 7.3 is a cause for this problem??
I have cacti 0.8.4 and RH 7.3
What is your rrdtool vesion? Mine is 1.0.35

Bruno Prigent · Post by **Bruno Prigent** » Wed Jan 14, 2004 4:57 am

I don't know if this is due to RedHat, I just said that since I change to another machine running Debian I didn't notice this problem. I changed the machine, the distrib and the polling base so everything changed

I'm using RRDtool 1.0.45
