[HOWTO] Add new MIB Variables to Cacti

[tafirol]

I will try to clarify what I´m looking for ; )
the thing is that I have an script running and I can use only one index by script, no problem there. But, now I have get information from 2 indexes, and I have no idea of what I have to write into the script. I hope that you understand my point.

thanks in advance,

Tafi ROL

Well I read the documentation and but the aid of others posts I could obtain it.

thanks...

[monachus]

please post your discovery here, so that the next person to have the question knows where to look. nothing is more frustrating than having a question, finding someone else who had the question, and then finding a post that says, "i figured it out," without any further information.

tx.

[tafirol]

Is true ....
Here is my script, I hope that it helps you.

I am having trouble getting this to work. I have followed the document very closely and even retried creating everything about 3 times. I am still getting the following error when i try to add the Data Query to the Device under the device configuration area. Any ideas?

Code: Select all

I tried snmpwalk and got good responses for these OIDs...

walking the OIDs has nothing to do with the errors you're posting. i believe that those errors mean that your data query is broken. if you go to the data query, you should see the line "Successfully located XML file" in green under the query information. It's as though the data query that you're adding doesn't have any information in it, which is what's creating those errors.

I think my Data Query is ok... as well as the data source. Can you see any problems in it? I also pasted my xml file. I am new to cacti but i think i have gotten the hang of it... this xml snmp query stuff is confusing me though. I have successfully gotten it to work using perl scripts to check nsclient on windows hosts.

Change your Data Query to "Get SNMP Data (Indexed)" instead of Script data.

[Alives]

so sorry about that

[monachus]

Does it work now?

[Alives]

yes that was it... naturally i feel stupid for overlooking such a vital selection...

[monachus]

pish posh. a second set of eyes is always a good thing. you'd been staring at it for hours, so something like that is easy to overlook. good job on including the screenshots - it made it possible for me to help.

i'm glad it worked!

Hello to all,

I tried the steps for making a SNMP query for cacti, but I made somewhere a mistake. the result is, thar no rra files are created and there is no image at the graph management.

I think the data query and the xml are correct, because I can see the information at device->associated data queries->verbose query.

About the combination about the Templates I am not sure.

Does anyone has an idea?


Thx
Moe

[monachus]

the steps in the how-to are complete. if you made a mistake and missed something, your best bet is to start over and go through it with greater care.

[moe_szyslak]

I have done evrything from the howto. I differed at No. 6, there ich made a graph to an existing host. Everything runs well at 'verbose query' - 'create graph for this host' etc.

But when I look at Graph Management I got the message 'open ...79.rrd - No such file or directory' and the RRA file is not in the directory.

A question about the field Data Query: Must there any entries at 'Associated Graph Templates' - 'Suggested Values' ?
