Overview
This collector monitors Supervisor instances.
It can collect metrics from:
Used methods:
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.
Setup
Prerequisites
No action required.
Configuration
File
The configuration file name for this integration is go.d/supervisord.conf.
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.
| Name | Description | Default | Required |
|---|---|---|---|
| update_every | Data collection frequency. | 1 | False |
| autodetection_retry | Recheck interval in seconds. Zero means no recheck will be scheduled. | 0 | False |
| url | Server URL. | http://127.0.0.1:9001/RPC2 | True |
| timeout | System bus requests timeout. | 1 | False |
Examples
HTTP
Collect metrics via HTTP.
jobs:
- name: local
url: 'http://127.0.0.1:9001/RPC2'
Socket
Collect metrics via Unix socket.
- 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.
jobs:
- name: local
url: 'http://127.0.0.1:9001/RPC2'
- name: remote
url: 'http://192.0.2.1:9001/RPC2'
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.
Troubleshooting
Debug Mode
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.
