Anyone have a template for djbdns(dnscache)with dnsstats.pl?

[Buckbeak]

I'm using Jeremy Kister's dnsstats tool at:

http://jeremy.kister.net/code/djbdns-stats/

I've got the everything setup on the dns server, and snmpd is presenting the data in one OID like this:

A:80 NS:0 CNAME:0 SOA:33 PTR:3 MX:4 TXT:0 AAAA:0 SRV:1 NAPTR:0 A6:0 IXFR:0 AXFR:0 ANY:0 effectiveness:109 other:0 total:121

I need to parse the data somehow in cacti, but don't know how.

Well, to be honest, you won't need any parsing in cacti cause this is _exactly_ the format cacti requires (never seen that before). You may define a simple one-liner that queries this OID and returns the string literally. Define a Data Input Method that refers to that one liner and define an output var for each value A, NS, CNAME etc. you want to have.
Then, it goes as usual
- define a Data Template for storing all wanted readings
- define a Graph Template for presentating the readings
Associate the Graph Template to your device (directly or indirectly using a Host Template)

I simple one liner what? Can you be more specific? I'm brand new to Cacti.

Here's what I came up with in case anyone else needs it:

#!/bin/sh

/usr/local/bin/snmpget -v1 -Ovqa -c communityname $1 .1.3.6.1.4.1.18689.0.1.3.1.1.14.100
.110.115.99.97.99.104.101.45.115.116.97.116.115 | sed 's/"//;s/"$//'


The last bit chops off the quotes at the beginning and end.
The OID is one continuous string (the message board is splitting it up).

Congratulations!
Did you make it with the other steps? If not, please post.

I'm making progress, but still no go.

I've created an input method, (shown below), and a data source with multiple data source items, but the graphs aren't working and the correct rrd file is not even in the rra directory. I have been able to get the graph working with a single datasource item (A), but not with multiple items. It's strange that the datasource appear to be created but there is no rrd file.

Working great on gentoo linux!!!

Funny as it may sound, I created djbdns-stats to work with cacti, but I haven't a clue how to configure cacti for it.

I've created simple objects in cacti, but haven't the first clue on how to efficiently integrate the djbdns stats.

Can someone give me a step-by-step (every needed click) to get cacti polling a host with djbdns-stats ?

I will include the howto along with credit in an upcoming release of djbdns-stats.

Thanks,

Jeremy

I have created a template for graphing all of the data returned by the excellent djbdns-stats scripts. Please let me know if you have any questions.

Thanks!

Thanks again for the template, that saved a lot of work. I think I found a problem with the djbdns-stats.sh script though.

Your query within that script,
/usr/local/bin/snmpget -v1 -Oaqv -c public $1 .1.3.6.1.4.1.18689.1.2.3.1.1.13.116.105.110.121.100.110.115.45.115.116.97.116.115 | sed 's/"//;s/"$//'

returned:

Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: SNMPv2-SMI::enterprises.18689.1.2.3.1.1.13.116.105.110.121.100.110.115.45.115.116.97.116.115

The prior snmget that BuckBeak did prior on this page worked fine.
#!/bin/sh

/usr//bin/snmpget -v1 -Ovqa -c communityname $1 .1.3.6.1.4.1.18689.0.1.3.1.1.14.100.110.115.99.97.99.104.101.45.115.116.97.116.115 | sed 's/"//;s/"$//'

returned:
A:5187 NS:0 CNAME:0 SOA:0 PTR:55 MX:7 TXT:0 AAAA:480 SRV:0 NAPTR:0 A6:0 IXFR:0 AXFR:0 ANY:0 effectiveness:190 other:0 total:5729

ps. I am on a Redhat Clone

Hi Everyone,

I am trying to get this script to work. It is currently configured on the DNS server and running the stat script gives me the following output

Code: Select all

# sh /var/www/html/scripts/djbdns-stats.sh the-dns
A:1 NS:5 ME:0 SOA:0 PTR:0 MX:0 TXT:120 AAAA:0 SRV:0 NAPTR:0 A6:0 IXFR:0 AXFR:0 ANY:0 effectiveness:0 other:0 total:130

The output seems fine but yet the graph is empty and the rrd file has UNKN values

Code: Select all

rrd_version = "0003"
step = 60
last_update = 1234004832
ds[tinydns_A].type = "GAUGE"
ds[tinydns_A].minimal_heartbeat = 120
ds[tinydns_A].min = 0.0000000000e+00
ds[tinydns_A].max = 1.0000000000e+04
ds[tinydns_A].last_ds = "UNKN"
ds[tinydns_A].value = 0.0000000000e+00
ds[tinydns_A].unknown_sec = 12
ds[tinydns_NS].type = "GAUGE"
ds[tinydns_NS].minimal_heartbeat = 120
ds[tinydns_NS].min = 0.0000000000e+00
ds[tinydns_NS].max = 1.0000000000e+04
ds[tinydns_NS].last_ds = "UNKN"

Could you kindly assist me getting this to work

Thank you

Thanks for all the input which got me going.
If you're on CentOS 5.4 with 5.3 net-snmp, then this will work for you and it is working for me.

It seems to me that with different version of net-snmp, you will likely have to tweak the OID in /etc/snmp/snmpd.conf.
