uWSGI

Plugin: go.d.plugin Module: uwsgi

Overview

Monitors UWSGI worker health and performance by collecting metrics like requests, transmitted data, exceptions, and harakiris.

It fetches Stats Server statistics over TCP.

This collector is supported on all platforms.

This collector supports collecting metrics from multiple instances of this integration, including remote instances.

Default Behavior

Auto-Detection

Automatically discovers and collects UWSGI statistics from the following default locations:

• localhost:1717

Limits

The default configuration for this integration does not impose any limits on data collection.

Performance Impact

The default configuration for this integration is not expected to impose a significant performance impact on the system.

Metrics

Metrics grouped by scope.

The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.

Per uWSGI instance

These metrics refer to the entire monitored application.

This scope has no labels.

Metrics:

Metric	Dimensions	Unit
uwsgi.transmitted_data	tx	bytes/s
uwsgi.requests	requests	requests/s
uwsgi.harakiris	harakiris	harakiris/s
uwsgi.respawns	respawns	respawns/s

Per worker

These metrics refer to the Worker process.

Labels:

Label	Description
worker_id	Worker ID.

Metrics:

Metric	Dimensions	Unit
uwsgi.worker_transmitted_data	tx	bytes/s
uwsgi.worker_requests	requests	requests/s
uwsgi.worker_delta_requests	delta_requests	requests/s
uwsgi.worker_average_request_time	avg	milliseconds
uwsgi.worker_harakiris	harakiris	harakiris/s
uwsgi.worker_exceptions	exceptions	exceptions/s
uwsgi.worker_status	idle, busy, cheap, pause, sig	status
uwsgi.worker_request_handling_status	accepting, not_accepting	status
uwsgi.worker_respawns	respawns	respawns/s
uwsgi.worker_memory_rss	rss	bytes
uwsgi.worker_memory_vsz	vsz	bytes

Alerts

There are no alerts configured by default for this integration.

Setup

Prerequisites

Enable the uWSGI Stats Server

See Stats Server for details.

Configuration

File

The configuration file name for this integration is go.d/uwsgi.conf.

The file format is YAML. Generally, the structure is:

update_every: 1
autodetection_retry: 0
jobs:
  - name: some_name1
  - name: some_name1

You can edit the configuration file using the edit-config script from the Netdata config directory.

cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config go.d/uwsgi.conf

Options

The following options can be defined globally: update_every, autodetection_retry.

Config options

Name	Description	Default	Required
update_every	Data collection frequency.	1	no
autodetection_retry	Recheck interval in seconds. Zero means no recheck will be scheduled.	0	no
address	The IP address and port where the UWSGI Stats Server listens for connections.	127.0.0.1:1717	yes
timeout	Connection, read, and write timeout duration in seconds. The timeout includes name resolution.	1	no

Examples

Basic

A basic example configuration.

Config

jobs:
  - name: local
    address: 127.0.0.1:1717

Multi-instance

Note: When you define multiple jobs, their names must be unique.

Collecting metrics from local and remote instances.

Config

jobs:
  - name: local
    address: 127.0.0.1:1717

  - name: remote
    address: 203.0.113.0:1717

Troubleshooting

Debug Mode

Important: Debug mode is not supported for data collection jobs created via the UI using the Dyncfg feature.

To troubleshoot issues with the uwsgi 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, open netdata.conf and look for the plugins 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 uwsgi

  To debug a specific job:

  ./go.d.plugin -d -m uwsgi -j jobName

Getting Logs

If you're encountering problems with the uwsgi collector, follow these steps to retrieve logs and identify potential issues:

• Run the command specific to your system (systemd, non-systemd, or Docker container).
• Examine the output for any warnings or error messages that might indicate issues. These messages should provide clues about the root cause of the problem.

System with systemd

Use the following command to view logs generated since the last Netdata service restart:

journalctl _SYSTEMD_INVOCATION_ID="$(systemctl show --value --property=InvocationID netdata)" --namespace=netdata --grep uwsgi

System without systemd

Locate the collector log file, typically at /var/log/netdata/collector.log, and use grep to filter for collector's name:

grep uwsgi /var/log/netdata/collector.log

Note: This method shows logs from all restarts. Focus on the latest entries for troubleshooting current issues.

Docker Container

If your Netdata runs in a Docker container named "netdata" (replace if different), use this command:

docker logs netdata 2>&1 | grep uwsgi
