bind9 statistics: statistics-channels

[fisher]

I recently added a bind9 monitoring way I have not seen before. Starting from 9.5(?) you can create a statistics channel in bind:

statistics-channels {
[ inet ( ip_addr | * ) [ port ip_port ] [allow { address_match_list } ]; ]
[ inet ...; ]
};

It creates a http server and outputs nothing but an xml file. For example to get the bind9 memory allocation (channel bound to localhost:8099):

wget --quiet --output-document=- http://127.0.0.1:8099|grep TotalUse | sed -e 's/<[^>]*>//g')


Now it is easy to add to the zabbix-agentd.conf and put into the monitoring process.

I use the "xml2" package to convert the xml format to text, but php or perl experts probably can develop much better solutions.

The default config for bind is (/etc/bind9/named.conf.local):

statistics-channels {
inet 127.0.0.1 port 8053 allow { 127.0.0.1; };
};

Zabbix agentd config:

UserParameter=bind9.queries,/usr/local/bind9getstats/bin/bind9getqueries.sh
UserParameter=bind9.memuse,/usr/local/bind9getstats/bin/bind9memuse.sh

The scripts are in a svn repo:
cd /usr/local && svn co http://svn.fisher.hu/bind9getstats

The usernameass is guest:guest

I attached a exported template. I believe all of these workin. At least for me

bind9memuse.sh Unit

the script bind9memuse.sh returns in Kbytes the use of memory ?? what is the unit ?

Regarding my experiences it returns the allocated memory in bytes.

Thanks for the info. I ended up doing this with some custom UserParameters that are similar to that script.

zabbix_agentd.conf:

UserParameter=bind.queries.in[*],curl http://localhost:8053/ 2>/dev/null | xml2 | grep -A1 "/isc/bind/statistics/server/queries-in/rdtype/name=$1$" | tail -1 | cut -d= -f2
UserParameter=bind.queries.out[*],curl http://localhost:8053/ 2>/dev/null | xml2 | grep -A1 "/isc/bind/statistics/views/view/rdtype/name=$1$" | tail -1 | cut -d= -f2

Then setup item keys like:

bind.queries.in[A]
bind.queries.in[PTR]
bind.queries.out[A]

etc.

I'm using bind 9.7.3 and this script "bind9getqueries.sh" constantly returning zero results. Sorry, but I'm dummy with linux systems.

Stupid! Forgot to install xml2 libraries.

Old thread, I know....

I wrote a couple of bash one-liners that don't require xml2

This one is for per-zone statistics and expects variable 1 = domain and variable 2 = stat type (QrySuccess, QryNXDOMAIN, etc):

UserParameter=bind.stat[*],curl -s http://localhost:8053 | sed -e '/>$1/,/\/counters/!d' | sed -e 's/ //g' | grep '<$2>' | sed -e 's/.*>\(.*\)<.*/\1/'

This one is for total query stats per record type and expects variable 1 = stat type (A, AAAA or PTR):

UserParameter=bind.stat.queriesin[*],curl -s http://localhost:8053 |  sed -e '/<queries-in>/,/<\/queries-in>/!d' | grep -A1 '<name>$1</name>' | tail -1 | sed -e 's/ //g' | sed -e 's/.*>\(.*\)<.*/\1/'

Thank you

Recently I had to use the following line (bind 9.7):

$1: domain
$2: qry type like A, PTR, MX, AAAA, etc.

UserParameter=bind.stat[*],curl -s http://localhost:8053 | sed -e '/>$1/,/\/resstat/!d' -e '/>$2</,/\/counter/!d' -e 's/<[^>]*>//g' -e '1,1 d'

[fisher]

ATM it looks there is no per domain stast available. I keep researching if the stats format is changed or what.

[fisher]

I have updated the oneliner:

UserParameter=bind.stat[*],curl -s http://localhost:8053 | sed -e '/>$1/,/\/counters/!d' -e /$2/\!d -e 's/.*>\([0-9]*\)<.*/\1/g'


It is one sed no grep or else.
