Hi Rossco ^^

About the associated graph query i believe why i had something : in fact i had created a new "Host Template" and i had associated the "Bind SNMP Request" and this graph (see the screen shot)

Now i have deleted the "associated graph templates".

When i'm going to "Collection Methods" -> "Data Input Methods" -> "Bind9 SNMP Request" (i have created it) i have :

In fact when i launch this command i have this :

Hi All ^^,

So apparently my graphs are working

I have value. I don't know why i had "nan" value and after few minutes i had true values.... Do you know when the value "nan" become a numeric value ??

Thank you very very much Rossco and Gandalf ^^

Hi Maillon

Apologies for not replying sooner, work has been a nightmare today.

I'm very glad to see you've gotten it working. In answer to your nan question, I believe it usually takes two full poller cycles to go from nan to meaningful results, although it depends on whether the snmp value you are querying is a gauge or a counter.

Anyhows, well done on fixing

Hi Gaansch/Tarpat.

Apologies for not replying sooner.

Could both of you confirm that your snmpd daemon accounts have the correct permissions for the .pl script? I'm not an expert on file system perms, but a chmod 777 /my/path/bind9-stats-snmpd.pl may help (tighten them afterwards, if you need to).

I'm presuming they already have execute permission as you've both run them.

cheers

Hi Rpssco,

Hi Gaansch

Yup, 755 may well work, as I said, I'm not an expert on the file perms, I just tinker

This really is bizarre. Not sure if I asked this before, but are you running snmpwalk locally or remotely? Maybe you have setup some snmp permissions in the config files?

Alternatively, how about we ignore the DNS script for the moment. If you replace the snmpd config line with something like (not tested, but sure I did something similar before):

"pass .1.3.6.1.4.1.2021.55 /usr/bin/logger SNMPD Script Called!"
or
"exec .1.3.6.1.4.1.2021.55 /usr/bin/logger SNMPD Script Called!"

Do you get any lines in your syslog? Obviously the snmpwalk will timeout, but the initial execution should have happened. You will need to restart the snmpd daemon when you do this.

If even that doesnt work, then perhaps you have multiple copies of the snmpd.conf on your system and snmpd is reading a different one?

Sorry, you can tell I'm running out of good ideas now...

Cheers

Hi Gaansch ^^,

Have you verify owner file ? And change if necessary with the command chown ?

Hi,

the owner of the file is snmp. The snmp daemon also runs as user snmp.

Hi Gaansch

Is it worthwhile confirming the snmpd service is definitely reading *this* file? Maybe stick some junk in your snmpd.conf and restart the service. It should either fail to start or complain loudly, indicating whether it is definitely reading the file?

Cheers

Hi,

okay, I've put the following line into /etc/snmp/snmpd.conf and the snmpd hasn't complained but started.

Hi Gaansch

Check your snmpd.log

I get the following in mine:

Hi Gaansch

Sorry, I'm out of ideas at this point. Maybe running smnpd in debug mode may help give you some insight?

Good luck.

Cheers

I got this script to work via SNMP to my DNS servers with no issues per say. It was getting info and cacti started populating graphs but then the next Day i reallized that it was no longer working and i was getting gaps on all my graphs on cacti. I checked into it and found that it was timing out getting the info via snmp from the name servers. Any ideas as to why this would be. I do know when I have graphing enabled the name server's cpu times go from .02, 015, 031 up to 1.57, 1.68, 1.07
