# Gearman
<img src="https://netdata.cloud/img/gearman.png" width="150"/>
Plugin: go.d.plugin
Module: gearman
<img src="https://img.shields.io/badge/maintained%20by-Netdata-%2300ab44" />
## Overview
Monitors jobs activity, priority and available workers. It collects summary and function-specific statistics.
This collector connects to a Gearman instance via TCP socket and executes the following commands:
- status
- priority-status
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 Gearman instances running on localhost that are listening on port 4730.
#### 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 Gearman instance
These metrics refer to the entire monitored application.
This scope has no labels.
Metrics:
| Metric | Dimensions | Unit |
|:------|:----------|:----|
| gearman.queued_jobs_activity | running, waiting | jobs |
| gearman.queued_jobs_priority | high, normal, low | jobs |
### Per Gearman instance
These metrics refer to the Function (task).
Labels:
| Label | Description |
|:-----------|:----------------|
| function_name | Function name. |
Metrics:
| Metric | Dimensions | Unit |
|:------|:----------|:----|
| gearman.function_queued_jobs_activity | running, waiting | jobs |
| gearman.function_queued_jobs_priority | high, normal, low | jobs |
| gearman.function_workers | available | workers |
## 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/gearman.conf`.
You can edit the configuration file using the `edit-config` script from the
Netdata [config directory](/docs/netdata-agent/configuration/README.md#the-netdata-config-directory).
```bash
cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config go.d/gearman.conf
```
#### Options
The following options can be defined globally: update_every, autodetection_retry.
<details open><summary>Config options</summary>
| 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 Gearman service listens for connections. | 127.0.0.1:11211 | yes |
| timeout | Connection, read, and write timeout duration in seconds. The timeout includes name resolution. | 1 | no |

## 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 `gearman` 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]`.
```bash
cd /usr/libexec/netdata/plugins.d/
```
- Switch to the `netdata` user.
```bash
sudo -u netdata -s
```
- Run the `go.d.plugin` to debug the collector:
```bash
./go.d.plugin -d -m gearman
```
### Getting Logs
If you're encountering problems with the `gearman` 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:
```bash
journalctl _SYSTEMD_INVOCATION_ID="$(systemctl show --value --property=InvocationID netdata)" --namespace=netdata --grep gearman
```
#### System without systemd
Locate the collector log file, typically at `/var/log/netdata/collector.log`, and use `grep` to filter for collector's name:
```bash
grep gearman /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:
```bash
docker logs netdata 2>&1 | grep gearman
```
