[elrond]

ello

I'am completly new to cacti and i can manage only simplest graph's from basic's manual part....

Could anybody give a hand and explain step by step how to create 2 cpu's utilization graph ???

I have two PIII 450Mhz on ubuntu serwer and I would like to monitor it's utilzation but i think that's involving little more "magic".....

Secondly i would like to have some mem graph. including maximum ram ( in mb) and it's utilization....

Could somebody describe things in more detailed way ????

(I think some nice tutorials covering litlle more than basic will be much apriciated) ....

(sorrry for my bad english)

Not claiming to solve your problem, but did you already consult the first link of my sig to find lot's of HowTos?

i'am sorry - i rushed to much before reading.....

... i learnt basic and i can create stadard graphs....

I would like graph with 2 cpu utilization on one box - i've found xml templates for this (thera are two major threads on this forum). But now i've stucked in place becoes rrd files won't create.....

Code: Select all

ERROR: opening '/usr/share/cacti/site/rra/

i've chcekd rights and give all for a try on rra dir but with no effect. rrd.log is empty....

Please tell us, which template you used and how you imported them

i took this template:

Code: Select all

cacti_graph_template_multi_cpu_utilization_on_2_processor_box.xml

from http://forums.cacti.net/about11615-0-asc-15.html
i've imported it by cacti import / export option from main menu. Next i've checked that when i create this graph for my host rrd files arent create (the error mentioned above) I've also tried to create those missig rrd files by hand: so i choosed datasource menu and from it CPU utilization and next *Turn Off Data Source Debug Mode and then rrd create code appeared which i tried to execute on my ubuntu machine and results in creteing those missing rrd files. Even then my graph is createing but it is blank....;/ It'looks like those data sources did not gather any daty of my cpu's utilization?????

The Template import was fine? No errors?
Then, please proceed as given by http://forums.cacti.net/viewtopic.php?t ... c&start=60
Are you using spine od cmd.php as a poller?

import went just fine,
i'am using cmd.php...

I tried everything and it seems that CPU utilization is not collectable from my ubuntu.
Cpu usage on ucd/net or load averge works fine, but when i try cpu utilization, host MiB cpu utilazation or even smnp generic table for OID 768 (first cpu?) and OID (769 - second CPU) all i get i blank graph ora nan values.....

(i'think also in those graphs in whish somthing is wrong (cpu utilization) rrd files are not created and i have to create them manualy as i described above)
