Monit
Monit
Plugin: python.d.plugin Module: monit
Overview
This collector monitors Monit targets such as filesystems, directories, files, FIFO pipes and more.
It gathers data from Monit’s XML interface.
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, this collector will attempt to connect to Monit at http://localhost:2812
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 python.d/monit.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 python.d/monit.conf
Options
There are 2 sections:
- Global variables
- One or more JOBS that can define multiple different instances to monitor.
The following options can be defined globally: priority, penalty, autodetection_retry, update_every, but can also be defined per JOB to override the global values.
Additionally, the following collapsed table contains all the options that can be configured inside a JOB definition.
Every configuration JOB starts with a job_name value which will appear in the dashboard, unless a name parameter is specified.
| Name | Description | Default | Required |
|---|---|---|---|
| update_every | Sets the default data collection frequency. | 1 | False |
| priority | Controls the order of charts at the netdata dashboard. | 60000 | False |
| autodetection_retry | Sets the job re-check interval in seconds. | 0 | False |
| penalty | Indicates whether to apply penalty to update_every in case of failures. | yes | False |
| name | Job name. This value will overwrite the job_name value. JOBS with the same name are mutually exclusive. Only one of them will be allowed running at any time. This allows autodetection to try several alternatives and pick the one that works. |
local | False |
| url | The URL to fetch Monit’s metrics. | http://localhost:2812 | True |
| user | Username in case the URL is password protected. | False | |
| pass | Password in case the URL is password protected. | False |
Examples
Basic
A basic configuration example.
localhost:
name : 'local'
url : 'http://localhost:2812'
Basic Authentication
Example using basic username and password in order to authenticate.
localhost:
name : 'local'
url : 'http://localhost:2812'
user: 'foo'
pass: 'bar'
Multi-instance
Note: When you define multiple jobs, their names must be unique.
Collecting metrics from local and remote instances.
localhost:
name: 'local'
url: 'http://localhost:2812'
remote_job:
name: 'remote'
url: 'http://192.0.2.1:2812'
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 Monit instance
These metrics refer to the entire monitored application.
This scope has no labels.
Metrics:
| Metric | Dimensions | Unit |
|---|---|---|
| monit.filesystems | a dimension per target | filesystems |
| monit.directories | a dimension per target | directories |
| monit.files | a dimension per target | files |
| monit.fifos | a dimension per target | pipes |
| monit.programs | a dimension per target | programs |
| monit.services | a dimension per target | processes |
| monit.process_uptime | a dimension per target | seconds |
| monit.process_threads | a dimension per target | threads |
| monit.process_childrens | a dimension per target | children |
| monit.hosts | a dimension per target | hosts |
| monit.host_latency | a dimension per target | milliseconds |
| monit.networks | a dimension per target | interfaces |
Alerts
There are no alerts configured by default for this integration.
Troubleshooting
Debug Mode
To troubleshoot issues with the monit collector, run the python.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.ddirectory, usually at/usr/libexec/netdata/plugins.d/. If that’s not the case on your system, opennetdata.confand look for thepluginssetting under[directories].cd /usr/libexec/netdata/plugins.d/ -
