HAProxy collector
HAProxy
is a free, very fast and reliable solution offering high availability, load
balancing, and proxying for TCP and HTTP-based applications.
This module will monitor one or more HAProxy
instances, depending on your configuration.
Requirements
HAProxy
v2.0+ (or 1.9r1+ for Enterprise users) with enabled PROMEX addon. PROMEX is not built by default withHAProxy
. It is provided as an extra component for everyone who wants to use it.
Metrics
Current implementation collects only backend metrics.
All metrics have "haproxy." prefix.
Metric | Scope | Dimensions | Units |
---|---|---|---|
backend_current_sessions | global | a dimension per proxy | sessions |
backend_sessions | global | a dimension per proxy | sessions/s |
backend_response_time_average | global | a dimension per proxy | milliseconds |
backend_queue_time_average | global | a dimension per proxy | milliseconds |
backend_current_queue | global | a dimension per proxy | requests |
backend_http_responses | proxy | 1xx, 2xx, 3xx, 4xx, 5xx, other | responses/s |
backend_network_io | proxy | in, out | bytes/s |

Configuration
Edit the go.d/haproxy.conf
configuration file using edit-config
from the
Netdata config directory, which is typically at /etc/netdata
.
cd /etc/netdata # Replace this path with your Netdata config directory
sudo ./edit-config go.d/haproxy.conf
Needs only url
to server's /metrics
endpoint. Here is an example for 2 servers:
jobs:
- name: local
url: http://127.0.0.1:8404/metrics
- name: remote
url: http://203.0.113.10:8404/metrics
For all available options please see module configuration file.
Troubleshooting
To troubleshoot issues with the haproxy
collector, run the go.d.plugin
with the debug option enabled. The output
should give you clues as to why the collector isn't working.
Navigate to the
plugins.d
directory, usually at/usr/libexec/netdata/plugins.d/
. If that's not the case on your system, opennetdata.conf
and look for theplugins
setting under[directories]
.cd /usr/libexec/netdata/plugins.d/
Switch to the
netdata
user.sudo -u netdata -s
Run the
go.d.plugin
to debug the collector:./go.d.plugin -d -m haproxy
