There are some interesting metrics on the traffic statistics endpoint. They appear to be sparse histogram buckets. It will take some digging, but we might be able to translate these into Prometheus buckets.

bind_exporter:
image: "prometheuscommunity/bind-exporter:v0.4.0"
container_name: "bind_exporter"
restart: "unless-stopped"
command: "-bind.stats-url http://fqdn-example:8053"

the container restart always. if change to "--bind.stats-url" the bind_up 0

can anybody help me?

Going over the XML, we've found a couple of issues.

Server Stats:
QryDuplicate is listed as an "error", it's actually a separate statistic for incoming query duplicates. It should be something like bind_queries_duplicated_total

QryRecursion seems to be missing from the stats. How about bind_query_recursions_total.

The issue appears to be the use of max(node_time_seconds{instance=~"$node:.*"}) which appears to not work in Prometheus 2.19, and a possible change in how Bind 9.16 reports uptime. The result is that changing the queries to time() - max(bind_boot_time_seconds{instance=~"$node:.*"}) produces sensible seeming results, but these are actually still off by an order of magnitude.

i.e. a Bind 9.16 reported boot time of 2020-07-14T21:10:48.999Z, with a current time of 2020-07-14T22:11:56.299Z will report incorrectly with the above, claiming 5.8 hours. I thought I had found the order of magnitude error, but then I noticed that something is still wrong because it wasn't updating correctly. That's when I noticed that bind_boot_time_seconds was moving. It went from 1594766106 to 1594740334, which is definitely not correct.

The actual Bind statistics do not reflect a change in the corresponding XML or JSON.

My environment:
CentOS 7.5 (Bind & Prometheus/Grafana)
Bind 9.9.4
Bind Exporter: 0.2.0_dev

Problem: I cannot find the under subject metric. I don't know if it's mapped in another variable, but I cannot find it in the metrics.

We run named in a container. I'd like to run bind_exporter in a container, too. However it looks like bind_exporter wants to run inside the same container as named? Is this correct? Is this required? Is there a HOWTO for configuring bind_exporter to run in a container beside the bind container?

Tried setting up bind_exporter on Centos7 with Go version 1.83. Make fails with below error

I installed several exporter without problems !

When type
go get github.com/neezgee/apache_exporter
nothing happend !!
Some help ?

Bind now supports stats over JSON.

I'm running into an issue during the command Make. Please see last line for error that I'm getting. I've also attached two colored screenshots showing command Make in run. Any suggestions how do I go about fixing? Thank you guys.

Hello,

It would be nice to have a metric with only the views available on the Bind server. That can allow a less tricky variable settings. Maybe something like:

bind_view_up{view="_bind"} 1
bind_view_up{view="_default"} 1

Thanks,

The server has been monitored for a week but according to some charts unchanged...
I attach screenshots.
How can I check that metrics work?

Hi,

Today I fixed an issue with the Debian package for bind_exporter (tests were not being run), and noticed all 32bit arches failing immediately. Turns out it is using uint for parsing statistics, which is not big enough in these architectures. The following patch fix the issue:

Hi,

I'm trying to use this grafana dashboard with bind_exporter:
https://grafana.com/dashboards/1666

bind_exporter started with below flags:
/usr/local/bin/bind_exporter -bind.pid-file /var/run/named/named.pid -bind.stats-groups "server,view,tasks"

But why I only can see below a few metrics items?

From the dashboard, seems there should be some other metrics we can use e.g. "bind_incoming_queries_total", "bind_incoming_requests_total", "bind_responses_total" ..etc..

my environment:

bind exporter is running， but not get bind records metric 。
help fix it.

We've been the current master in production for a while and it's pretty stable. Can we get a proper release including tarballs for each arch/os? I'm happy to take this over if you need help if you add me as collaborator to this repository.

Hi,
it would be nice to export the build_info like other exporters does.

# HELP node_exporter_build_info A metric with a constant '1' value labeled by version, revision, branch, and goversion from which node_exporter was built.
# TYPE node_exporter_build_info gauge
node_exporter_build_info{branch="release",goversion="go1.8.3",revision="d7d629e9a1400482f2801207ba4e4f2f6ee80b33",version="0.14.0"} 1

With bind_exporter, DNS will have a sudden increase in parsing time.

the 10000 time about 6% increase in parsing time

curl http://127.0.0.1:853 The data is about 18m.

One thread CPU of BIND9 is 100%

Hi,
I wanted to report that some vendors are actually outdated and megacheck report some possible errors.
Are you thinking about doing a new release? TravisCI should use go1.8.x instead of 1.7.

See,

bind/v2/v2.go:108:9: should use type conversion instead of struct literal (S1016)
bind_exporter.go:476:28: prometheus.Handler is deprecated: Please note the issues described in the doc comment of InstrumentHandler. You might want to consider using promhttp.Handler instead (which is not instrumented).  (SA1019)

In line with node_exporter recently removing the vendor directory, it would simplify packaging if bind_exporter merely used go.mod and modern dependency management.

It looks like a few other things could do with a bit of modernizing too (like the removal of GO111MODULE=on)

What do you think, @SuperQ ?

Hi,

bind_recursive_clients is now counter, but should be a gauge. Since its current connected clients.

The graphs in grafana https://grafana.com/grafana/dashboards/1666 are cool, but there is absolutely no mention anywhere in documentation or graphs themselves, what are the units?

I can see for example incoming queries - what are they:

• Queries since launch?
• Queries per second?
• Queries per minute?
• Queries since last fetch?

It would be really useful to know this, seeing just numbers with no context is misleading and useless

See https://github.com/digitalocean/bind_exporter/search?utf8=%E2%9C%93&q=incomming:

incomming should be incoming

I have set the bind.pid-file to the right location but the exporter doesn't show any process metrics. The resolver and response metrics show up fine. I am mostly interested in the file descriptor info.

I am having issues while setting up this project can someone please help me with the same and reply me if this project is alive so that I can post logs of my problem and get this up.

Similar to the other official Prometheus projects, we have been switching logging from github.com/prometheus/common/log to github.com/prometheus/common/promlog. This uses go-kit for logging.

i konw this bind_exporter has many index of bind , but i dont konw the important index, so what is the important index ,which we should pay attention to sth ?
Waiting for your reply!

Hi!

Would it be possible to have a new release including a Linux amd64 binary build?
This would really help us out over at VoxPupuli. See voxpupuli/puppet-prometheus#312 (comment)

Thanks,
Alex

When using a custom port for the statistics channel on an SELinux enabled host, the port needs to be tagged with SELinux policy.

https://bugzilla.redhat.com/show_bug.cgi?id=1778349

add custom port to dns_port_t type, which would allow bind to listen on that port.

$ (sudo) semanage port -a -t dns_port_t -p tcp 8053

All current port assigned to a type could be obtained by command

$ semanage port -l | grep dns_port_t

I've added master example.com zone to Bind configuration, but didn't create master DNS zone on server, reloaded Bind and got following Bind errors:

May  7 11:43:14 hostname named[8104]: zone example.com/IN: loading from master file /master/example.com.zone failed: file not found
May  7 11:43:14 hostname named[8104]: zone example.com/IN: not loaded due to errors.

Bind itself handles this gracefully and continues serving existing zones. Bind exporter, however, started failing immediately with following errors:

Hi, I'm running this with bind 9.10: 1:9.10.3.dfsg.P2-4 under ubuntu, and there is barfs with:

ERRO[0028] Failed to unmarshal XML response: expected element type <isc> but have <statistics>  source=bind_exporter.go:219

When starting up the server with -bind.stats-groups=system,view,tasks the exporter tries to export duplicate metrics, which causes errors. Appears to be because the -bind.stats-groups switch only appends to the existing default rather than overwriting it.

See sample XML output.

this is my environment:
bind version: 9.10.7
bind_exporter: version 0.2.0-dev (branch: master, revision: fdbe49f)
go version: go1.9.4
pull_interval: 1m

test via go program :
startDomain := time.Now()
_, err := net.LookupHost("test.com")
elapsed := time.Since(startDomain)

in every same interval time ,i find client query is very slow than other time ,query time about is 100ms ， and this time is monitor pull data；

Hi, really having a tough time with golang and I can't get make to work at all (as noted in similar issue threads) so instead of compiling I was hoping to just use the pre-compiled binary for v0.2.0

Release downloaded from:
https://github.com/digitalocean/bind_exporter/releases/download/v0.2.0-dev/bind_exporter

Works perfectly fine on my Mac:

Macbook$ ./bind_exporter
INFO[0000] Starting bind_exporter (version=0.2.0-dev, branch=master, revision=dae68f9a72da14e080aea554b7d4f1495904ba1a)  source="bind_exporter.go:455"
INFO[0000] Build context (go=go1.8.3, user=root@a8276f7e0479, date=20

Won't run at all on Ubuntu 16:

Linux_Server$ ./bind_exporter
-bash: ./bind_exporter: cannot execute binary file: Exec format error

The compilation from source issues I'm experiencing are the same type error noted here from another user: #32

I'll continue to hack away at it but any help is very much appreciated.
