Supervisor

Plugin: go.d.plugin Module: supervisord

Overview

This collector monitors Supervisor instances.

It can collect metrics from:

• unix socket
• internal http server

Used methods:

• supervisor.getAllProcessInfo

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

This integration doesn't support auto-detection.

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 Supervisor instance

These metrics refer to the entire monitored application.

This scope has no labels.

Metrics:

Metric	Dimensions	Unit
supervisord.summary_processes	running, non-running	processes

Per process group

These metrics refer to the process group.

This scope has no labels.

Metrics:

Metric	Dimensions	Unit
supervisord.processes	running, non-running	processes
supervisord.process_state_code	a dimension per process	code
supervisord.process_exit_status	a dimension per process	exit status
supervisord.process_uptime	a dimension per process	seconds
supervisord.process_downtime	a dimension per process	seconds

Alerts

There are no alerts configured by default for this integration.

Setup

Prerequisites

No action required.

Configuration

File

The configuration file name for this integration is go.d/supervisord.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/supervisord.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
url	Server URL.	http://127.0.0.1:9001/RPC2	yes
timeout	System bus requests timeout.	1	no

Examples

HTTP

Collect metrics via HTTP.

Config

jobs:
  - name: local
    url: 'http://127.0.0.1:9001/RPC2'

Socket

Collect metrics via Unix socket.

Config

- name: local
  url: 'unix:///run/supervisor.sock'

Multi-instance

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

Collect metrics from local and remote instances.

Config

jobs:
  - name: local
    url: 'http://127.0.0.1:9001/RPC2'

  - name: remote
    url: 'http://192.0.2.1:9001/RPC2'

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 supervisord 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 supervisord

Getting Logs

If you're encountering problems with the supervisord 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 supervisord

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 supervisord /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 supervisord
