An nginx module for sending statistics to statsd.
This is how to use the nginx-statsd module:
http {
# Set the server that you want to send stats to.
statsd_server your.statsd.server.com;
# Randomly sample 10% of requests so that you do not overwhelm your statsd server.
# Defaults to sending all statsd (100%).
statsd_sample_rate 10; # 10% of requests
server {
listen 80;
server_name www.your.domain.com;
# Increment "your_product.requests" by 1 whenever any request hits this server.
statsd_count "your_product.requests" 1;
location / {
# Increment the key by 1 when this location is hit.
statsd_count "your_product.pages.index_requests" 1;
# Increment the key by 1, but only if $request_completion is set to something.
statsd_count "your_product.pages.index_responses" 1 "$request_completion";
# Send a timing to "your_product.pages.index_response_time" equal to the value
# returned from the upstream server. If this value evaluates to 0 or empty-string,
# it will not be sent. Thus, there is no need to add a test.
statsd_timing "your_product.pages.index_response_time" "$upstream_response_time";
# Increment a key based on the value of a custom header. Only sends the value if
# the custom header exists in the upstream response.
statsd_count "your_product.custom_$upstream_http_x_some_custom_header" 1
"$upstream_http_x_some_custom_header";
proxy_pass http://some.other.domain.com;
}
}
}
