Beanstalk

Plugin: go.d.plugin Module: beanstalk

Overview

This collector monitors Beanstalk server performance and provides detailed statistics for each tube.

Using the beanstalkd protocol, it communicates with the Beanstalk daemon to gather essential metrics that help understand the server's performance and activity. Executed commands:

• stats.
• list-tubes.
• stats-tube.

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

By default, it detects Beanstalk instances running on localhost that are listening on port 11300.

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 Beanstalk instance

These metrics refer to the entire monitored application.

This scope has no labels.

Metrics:

Metric	Dimensions	Unit
beanstalk.current_jobs	ready, buried, urgent, delayed, reserved	jobs
beanstalk.jobs_rate	created	jobs/s
beanstalk.jobs_timeouts	timeouts	jobs/s
beanstalk.current_tubes	tubes	tubes
beanstalk.commands_rate	put, peek, peek-ready, peek-delayed, peek-buried, reserve, reserve-with-timeout, touch, use, watch, ignore, delete, bury, kick, stats, stats-job, stats-tube, list-tubes, list-tube-used, list-tubes-watched, pause-tube	commands/s
beanstalk.current_connections	open, producers, workers, waiting	connections
beanstalk.connections_rate	created	connections/s
beanstalk.binlog_records	written, migrated	records/s
beanstalk.cpu_usage	user, system	percent
beanstalk.uptime	uptime	seconds

Per tube

Metrics related to Beanstalk tubes. This set of metrics is provided for each tube.

Labels:

Label	Description
tube_name	Tube name.

Metrics:

Metric	Dimensions	Unit
beanstalk.tube_current_jobs	ready, buried, urgent, delayed, reserved	jobs
beanstalk.tube_jobs_rate	created	jobs/s
beanstalk.tube_commands_rate	delete, pause-tube	commands/s
beanstalk.tube_current_connections	using, waiting, watching	connections
beanstalk.tube_pause_time	since, left	seconds

Alerts

The following alerts are available:

Alert name	On metric	Description
beanstalk_server_buried_jobs	beanstalk.current_jobs	number of buried jobs across all tubes. You need to manually kick them so they can be processed. Presence of buried jobs in a tube does not affect new jobs.

Setup

Prerequisites

No action required.

Configuration

File

The configuration file name for this integration is go.d/beanstalk.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/beanstalk.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 Beanstalk service listens for connections.	127.0.0.1:11300	yes
timeout	Connection, read, and write timeout duration in seconds. The timeout includes name resolution.	1	no
tube_selector	Specifies a pattern for which Beanstalk tubes Netdata will collect statistics.	*	no

Examples

Basic

A basic example configuration.

Config

jobs:
  - name: local
    address: 127.0.0.1:11300

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: 127.0.0.1:11300

  - name: remote
    address: 203.0.113.0:11300

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 beanstalk 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 beanstalk

Getting Logs

If you're encountering problems with the beanstalk 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 beanstalk

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 beanstalk /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 beanstalk
