新版本Openresty 1.15.8.1 启动报错
测试系统环境： CentOS 7.5.1804
参考安装链接
#1、先安装好Openresty 1.15.8.1
yum install yum-utils
yum-config-manager --add-repo https://openresty.org/package/centos/openresty.repo
yum -y install openresty --enablerepo="openresty"
ln -s /usr/local/openresty/nginx/sbin/nginx /usr/local/sbin/nginx
#2、安装 扩展程序
cd /opt
git clone http://www.github.com/hamishforbes/lua-resty-consul
git clone https://github.com/knyar/nginx-lua-prometheus
git clone https://github.com/vovolie/lua-nginx-prometheus
mkdir -p /usr/local/openresty/nginx/conf/conf.d
cp lua-nginx-prometheus/counter.conf /usr/local/openresty/nginx/conf/conf.d/
#3、编辑 counter.conf 文件
[root@test-elk3 conf]# cat /usr/local/openresty/nginx/conf/conf.d/counter.conf
# Please copy to nginx's conf.d directory
# Set search paths for pure Lua external libraries (';;' is the default path):
lua_package_path "/opt/nginx-lua-prometheus/?.lua;;/opt/lua-resty-consul/lib/resty/?.lua;;/opt/lua-nginx-prometheus/lib/?.lua;;";
# Set Prometheus global dict
lua_shared_dict prometheus_metrics 10M; #init 10M memory
lua_shared_dict uri_by_host 10M;
lua_shared_dict global_set 1M;
# Development option, if deploy production, pls cache on!
lua_code_cache off;
init_by_lua_block {
counter = require 'counter'
counter.init()
consul_host = "192.168.9.53"
consul_port = 8500
}
log_by_lua_block {
counter.log()
}
# Expose prometheus's metrics scrape port
server {
listen 9145;
allow all;
access_log off;
location /metrics {
content_by_lua 'prometheus:collect()';
}
}
#4、启动openresty报错如下

配置Prometheus服务发现
您好！
能否麻烦详细给个关于Prometheus配置Consul 服务发现的例子？我在Consul官方网站下载了软件，解压缩后是一个consul的可执行程序，模具前不清楚Prometheus如何配置服务发现，其它模块都已经安装好了。
谢谢！
是否支持tengine?
是否支持tengine version2.2.0?

修改counter.conf里面的路径之后，重启nginx，报错了
lua_package_path "/mnt/work/nginx-lua-prometheus/?.lua;/mnt/work/lua-resty-consul/lib/resty/?.lua;/mnt/work/lua-nginx-prometheus/lib/?.lua;;";
报的错：

请教grafana如何配置呢?
在datasource里
HTTP的URL配置http://ip:port或者http://ip:port/metrics
Access配置Browser
save&test的时候 就一个红色的叹号 没错误信息
不懂是哪里配错了?
lua_code_cache设置成off导致init_by_lua_block是每个请求执行一遍
https://github.com/openresty/lua-nginx-module#init_by_lua
In case that the lua_code_cache directive is turned off (default on), the init_by_lua handler will run upon every request because in this special mode a standalone Lua VM is always created for each request.
请教下，怎么配置对具体的URL统计和监控呢
就像你的截图当中，我看到是对具体的某些API接口URL做了监控，这些具体该如何配置呢？
我按照你的这个流程操作下来，但是发现并没有针对URL的统计
无法使用？
你好，我按照你的文档进行安装，访问报错。
consul 和 openresty 正常启动。
ls /data
lua-nginx-prometheus lua-resty-consul nginx-lua-prometheus
把counter.conf拷贝到了 conf.d/counter.conf .
修改如下：
lua_package_path "/data/nginx-lua-prometheus/prometheus.lua;;/data/lua-resty-consul/lib/resty/consul.lua;;/data/lua-nginx-prometheus/lib/counter.lua;;";
lua_shared_dict prometheus_metrics 10M;
lua_shared_dict uri_by_host 10M;
lua_shared_dict global_set 1M;
lua_code_cache off;
init_by_lua_block {
counter = require 'counter'
counter.init()
consul_host = "192.168.111.11"
consul_port = 8500
}
log_by_lua_block {
counter.log()
}
server {
listen 9145;
allow all;
location /metrics {
content_by_lua 'prometheus:collect()';
}
}
但是访问：http://192.168.111.12:9145/metrics 报500错误。
日志：
2018/04/14 20:23:56 [error] 5202#5202: *1 lua entry thread aborted: runtime error: content_by_lua(counter.conf:23):1: attempt to index global 'prometheus' (a nil value)

我不知道是不是lua_package_path配置的有问题，但是你的文档中没有写清晰，请告知如何配置？？？谢谢。
test.json文件是什么？
