Cacti

I just noticed that the speed of my interfaces is mixed up. the number that is supposed to represent the speed of outgoing connection actually shows incoming stream and vice versa. I was about to change descriptions in the template when I saw that the speed is shown correctly on my trunk port that c...

That'll teach you to delete stuff you're not suppose to :P. Why not restore from your weekly backups? The left overs you didn't list from my install: Load Average %8.2lf Ping %8.2lf ms Percentage as Decimal %6.2lf%% Actually I thought that Iwas deleting them for one particular graph... and I don't ...

I accidentally deleted something from Management -> Graphs Management CDEFs. Unfortunatelly I don't remember what line I deleted. And besides that, I also deleted a line from GPRINT Presets. now I have only 2 left. ( Normal and Exact Numbers) Since I did it, I haven't been able to add custom graphs....

See the "Data Sources", find your host and Data Source by filtering. Then edit the data source in question and change the OID field.

thanks a lot for your help

i created a couple of different graphs which use different OIDs
but all of them were created from this template
so the OID field is porbably supposed to be empty

Reinhard

here is the screenshot of the template
when I create a copy of it where should I change OID? I can't find a place where it is stored in cacti

gandalf wrote:Yes, please send screenshot of the Data Template
Reinhard

its default template - SNMP - Generic OID Template. I did change anything there.
Data Templates [edit: SNMP - Generic OID Template]

Reinhard

I created the graph by using this part of manual
http://www.cacti.net/downloads/docs/htm ... p_oid.html
if you still need me to post screenshots, let me know and I'll post them

Reinhard

No and yes.
It does NOT have it as a default CDEF, but you may simply add this CDEF and apply it to all grph items you want.
Reinhard

could you please explain what CDEF is and how I apply it?

Hi UstasAlex, Please forgive me if I did not understand your question correctly. Cacti shows the unknown data in gray color and if your cacti does not then you can add it to the graph template. it seems to me that gray area or 0 line/area are the same. Regards, I will try to describe the problem Im...

When SNMP query doesn't return anything, Cacti draws nothing and thats fine, but when SNMP starts working again Cacti fills the empty space on the graph as if there was no problem. Is there any way to fix it? in MRTG for instance there is a "unknaszero option". Does Cacti have anything lie...

Is it possible to change OID for a graph without deleting it and then creating a new one ? if so, please, expalin how to do that
