PowerDNS Recursor Templates [updated 29/7/09]

[Howie]

Code: Select all

# pdns_control show \*

corrupt-packets=0,deferred-cache-inserts=0,deferred-cache-lookup=0,latency=0,packetcache-hit=4,packetcache-miss=5,packetcache-size=0,qsize-q=1,query-cache-hit=0,query-cache-miss=8,recursing-answers=0,recursing-questions=0,servfail-packets=0,tcp-answers=0,tcp-queries=0,timedout-packets=0,udp-answers=9,udp-queries=9,udp4-answers=9,udp4-queries=9,udp6-answers=0,udp6-queries=0,

works for me. Not the same format, so you'd need to alter the script, of course.

The error xseries had was using the wrong OID as far as I can see...

I was walking this OID .1.3.6.1.4.1.8072.1.3.2.4.1.2. I will check my configuration one again

Ok. I found solution. I had to change some permissions for /var/run/pdns_recursor.controlsocket file.
Now everything works fine.
Thanks for templates Howie

P.S. Sorry for my English

for those of you asking about authoritive dns server stats, see my thread here

Does somebody have any idea if it still works with Cacti 0.8.7g. Keep getting NaN in my graphs.

[gooeyblob]

It seems like when you restart the pdns service, the graphs jump to some insane number. Is this because of the way COUNTERs are handled and how the statistics are reset after a restart?

I still get the following error:

root@machine:/home/me# snmpwalk -v2c -ctest 127.0.0.1 .1.3.6.1.4.1.8072.1.3.2.4.1.2
NET-SNMP-EXTEND-MIB::nsExtendOutLine."pdns-rec".1 = STRING: Fatal: Unable to generate local temporary file in directory '/var/run/': Permission denied

When i change the snmp service to run as root the problem is resolved, but i would like to run snmp as snmp user

Sirs,
I really need you help

I have installed snmpd (apt-get install snmpd) and added

Code: Select all

extend pdns-rec /usr/local/bin/pdns_stats

followed the instructions that is written by Howie.

I also, installed cacti (apt-get install cacti) did the upgrade to 0.8.7g and all went fine importing the xml files.

I'm waiting since 2 hours refreshing the graph pages but cacti seems not able to collect data in order to draw the graphs!!!

I tried the below test and got this message... any help would be highly appreciated!!!

CacheX:/# snmpwalk -v2c -c public 127.0.0.1 .1.3.6.1.4.1.8072.1.3.2.4.1.2
NET-SNMP-EXTEND-MIB::nsExtendOutLine = No more variables left in this MIB View (It is past the end of the MIB tree)

Did you restart snmpd after adding that like to the snmpd.conf file?

You need to figure out why you can't snmpwalk that oid and get data. Cacti will never work if snmp doesn't return the data.

[maroon]

I did restart the snmpd service and I also restart the server

still no luck !!!

How can I know that snmp is sending data to cacti or catci is collecting data???

[maroon]

it is drawing the graphs but getting NAN !!!!
it is weird!

please help !!!

Would you please paste the output of the aforementioned OID if you run snmpwalk?
