I do not have to say that I would really love it to work on my platform, but I am getting graphs as the 3rd one described by you.

here it is:

Code: Select all

snmpset -v 2c -c readwrite 127.0.0.1 NET-SNMP-AGENT-MIB::nsCacheTimeout.1.3.6.1.2.1.4.34 = 0

this will disable data caching and can kick down you performance greatly

there are plenty of other cache settings (dominating 60 secs) - haven't tired them yet:

Hmm, that is not cool. Do you have any estimates of how much perfromance degradation I can expect? (I do not want to monkey with this if the performance impact is huge). Thanks.

it depends on lots of factors:

¤server type,
¤physical/logical interfaces count,
¤snmpd usage,

if a linux machine you're monitoring runs just a simple cacti environment and you're monitoring 1 physical interface with zond - you should not notice any performance loss at all.

if a linux machine represents core router with two 10Gbit interfaces and 20K vlans, and you're counting per-vlan traffic walking 1000 oids at once - then snmpd might finish with 99% system load and even "core dumped".

but these are only thoughts from my personal experience. you should ask at net-snmp mailing lists for details, because caching can be enabled/disabled for apropriate mibs(tables), you can as well use 1,10,15 secons instead of 0(disable) etc...

Thanks, I will. If I find some more useful information, I will post it on the forum.

K, i'm interested in this to as well as many others I think...

Hi,
I ınstalled Zond my cacti (0.8.7b)
Zond works but i thin something wrong. If you look at the screenshot you see that cacti 5 min. graph inbound traffic 3.8 Mbps and outbound traffic reaches. But zond values very different. Zond inbound traffic only 50 bps and outbound is 1.5 Mbps.
Can anybody tells me difference between zond and cacti graphic. I know zond real time but although zond show realtime i think this difference is huge.
Thnx

are you using some cdefs on current graph template?
try monitoring apropriate oids (you can find them i cacti's snmp poller cache)
with something like STG (snmp traffic grapher) http://leonidvm.chat.ru

I allways use this tool to determine zond problems against cacti problems.

TFC · Post by **TFC** » Fri Mar 28, 2008 6:42 am

Hi, I check zond by using STG. Same problem occurs. STG shows traffik Megabit/sec levels . But Zond shows bits levels. STG values are rgiht because they cacti values and line's behaviour.
As you see below there is two graphic. Both are run ans observe at the same time .One of them is taken from STG other one is from Zond. I circled inbound and outbound max values. Both graphics's shape are similar. But values are different.
I think some mutiplier or measuring problem exist. Right?

can you please export graph template being used on that chart and upload it there, so I could check cdef calculation?

TFC · Post by **TFC** » Wed Apr 02, 2008 8:42 am

Hi,
I use this "turn bytes into bits" as CDEF:

cdef=CURRENT_DATA_SOURCE,8,*

And here is the my graph template (shown picture)
And you can see inbound graph item detail (CURRENT-LAST)

it would be better if you could export templates using "Console->Export Templates", because i'll have to perform deep debugging on this template.

you can upload it here or send within private message to me.

thanx

Regardless if I use IE or Firefox, I'm getting blank windows when I try to use the Zond button in my graphs. I've gone through the posts on this forum, and I've gone through the debugging found on the netzond site. When i run the debugging session, I get the following output. It looks to me like I'm getting a valid return:

I saw other posts where users were getting non-numeric results back, but I don't see any error here.

When I run the Java Console however, I see the following:
