My statsd server is not receiving any packets from nginx, and as far as I can tell, the system is not sending any UDP requests.

I've only monitored:

netstat -npuc

to check for outgoing UDP transactions. Nothing shows up.

I'm running nginx 1.7.9, with spdy, ssl, and this module. Any ideas you have to help me figure out what's going on here?

Hello,

after upgrading some packages via apt-get upgrade in ubuntu 10.04, nginx with the nginx-statsd module compiled works very unstable (i.e. about every 2nd request fails with no data sent to the client). The syslog contains a lot of these errors:

Dec 12 01:25:56 server1 kernel: [ 5066.291028] nginx[18247]: segfault at 0 ip 000000000040c161 sp 00007fff26117c60 error 4 in nginx[400000+fd000]

And the nginx error.log has many of these:

2012/12/12 01:25:56 [alert] 10491#0: worker process 18247 exited on signal 11

I recompiled, downloaded the newest versions of nginx, pcre and updated everything but the only thing that seems to help is to disable nginx-statsd by either not compiling it (i.e. do not add --add-module=/path/to/nginx-statsd) or to just not use any statsd-related configuration directives.

I use nginx 1.2.6 in ubuntu 10.04 server. Linux server1 2.6.32-40-server #87-Ubuntu SMP Tue Mar 6 02:10:02 UTC 2012 x86_64 GNU/Linux

The mod_statsd project for Apache provides very detailed statistics by logging every hit and it's response code.

By default, they have them by individual page types, but I roll up to the top level domain to get the following entries, which I find extremely useful.

www_hostname_com.GET.200.count
www_hostname_com.GET.403.count
www_hostname_com.GET.404.count
www_hostname_com.POST.200.count

Is it possible to duplicate this functionality?

I am forking this to UKHomeOffice so I can tag a release there and have definitely stable known code, but may be nice for others to have a tagged version here.

Added missing static specifiers.

As of the above commit, the ngx_udp_connect function is static (not exported) and so cannot be used by this library.

I don't know of a good fix, but if some suggests one to me I will attempt to implement it.

Currently I'm applying this patch to my nginx build.

Does it (nginx-statsd) support POST requests. I configure as:
statsd_count "myapp.request" 1;
but it's only sends GET requests to statsd server. Please give me some information. Thanks

While looking for a quick and easy way to send some nginx data to statsd I came upon this module and while it's doing its job properly, there is one thing that was bothering me: for each configured metric it would generate a separate UDP packet. This would mean that when used in a relatively large farm with multiple vhosts, each with multiple metrics defined, it would generate a flurry of packets, even when not under heavy load, that would hammer the statsd service. One obvious solution to this was to combine multiple metrics in a single packet, and the following patch tries to do just that.

As I have written in details here http://serverfault.com/questions/597195/sending-data-to-statsd-does-not-work-in-some-locations-with-content-by-lua-file I have a problem with this module not pushing data into statsd when I exit my lua script with return ngx.redirect .

I don't want to use https://github.com/lonelyplanet/openresty-statsd as it would require me to add statsd pushing code to all my scripts..

Could you help me please resolve this issue then?

objs/addon/nginx-statsd-master/ngx_http_statsd.o: In function ngx_http_statsd_udp_send': /tmp/soft/nginx-statsd-master/ngx_http_statsd.c:367: undefined reference to ngx_udp_connect'
collect2: ld returned 1 exit status

according to https://graphite.readthedocs.io/en/latest/tags.html
tag format is my.series;tag1=value1;tag2=value2
however nginx-statsd escapes too many kinds of characters ,
to get tag compatibility
need to replace the escape mask from line:

		                    /* ?>=< ;:98 7654 3210  /.-, +*)( '&%$ #"!  */
	//	0xfc00bfff, /* 1111 1100 0000 0000  1011 1111 1111 1111 */
		0xD400BFFF, /* 1101 0100 0000 0000  1011 1111 1111 1111 */

this repo looks out of maintenance for a long time, posting the patch here so that everyone can see it

I want to count incoming/outgoing traffic through statsd. This works:

statsd_count "mysite.outgoing_body_traffic" $body_bytes_sent;

However, $body_bytes_sent does not include HTTP headers. When I try one of the following, nginx won't start:

statsd_count "mysite.outgoing_traffic" $bytes_sent;
statsd_count "mysite.incoming_traffic" $request_length;

The error messages I get:

Restarting nginx: nginx: [emerg] unknown "bytes_sent" variable
Restarting nginx: nginx: [emerg] unknown "request_length" variable

Any ideas why $body_bytes_sent works perfectly but $bytes_sent and $request_length are unknown variables? Logging them to a file (via log_format) works.

Thanks!

This repo is dead, the addon no longer compiles with current nginx, and the link to www.zebrafishlabs.com is dead. Is there a fork that is being maintained/other people are using? I checked a few and didn't see any with stars.

Hello.
If you make nginx with "--with-openssl=..." then shared (system) openssl lib should not be used. But nginx-statsd "config" adds "-lssl".

I'm receiving wrong targets in graphite from statsd. All the dashes are replaced by underscores. is this because of this function
https://github.com/zebrafishlabs/nginx-statsd/blob/master/ngx_http_statsd.c#L712

And if so then why are you escaping the targets like that?
