-# Redis monitoring with Netdata
-
-Monitors database status. It reads server response to `INFO` command.
-
-Following charts are drawn:
-
-1. **Operations** per second
-
- - operations
-
-2. **Hit rate** in percent
-
- - rate
-
-3. **Memory utilization** in kilobytes
-
- - total
- - lua
-
-4. **Database keys**
-
- - lines are creates dynamically based on how many databases are there
-
-5. **Clients**
-
- - connected
- - blocked
-
-6. **Slaves**
-
- - connected
-
-## Configuration
-
-Edit the `python.d/redis.conf` configuration file using `edit-config` from the Netdata [config
-directory](/docs/configure/nodes.md), which is typically at `/etc/netdata`.
-
-```bash
-cd /etc/netdata # Replace this path with your Netdata config directory, if different
-sudo ./edit-config python.d/redis.conf
-```
-
-```yaml
-socket:
- name : 'local'
- socket : '/var/lib/redis/redis.sock'
-
-localhost:
- name : 'local'
- host : 'localhost'
- port : 6379
-```
-
-When no configuration file is found, module tries to connect to TCP/IP socket: `localhost:6379`.

-# netdata python.d.plugin configuration for redis
-#
-# This file is in YaML format. Generally the format is:
-#
-# name: value
-#
-# There are 2 sections:
-# - global variables
-# - one or more JOBS
-#
-# JOBS allow you to collect values from multiple sources.
-# Each source will have its own set of charts.
-#
-# JOB parameters have to be indented (using spaces only, example below).
-
-# ----------------------------------------------------------------------
-# Global Variables
-# These variables set the defaults for all JOBs, however each JOB
-# may define its own, overriding the defaults.
-
-# update_every sets the default data collection frequency.
-# If unset, the python.d.plugin default is used.
-# update_every: 1
-
-# priority controls the order of charts at the netdata dashboard.
-# Lower numbers move the charts towards the top of the page.
-# If unset, the default for python.d.plugin is used.
-# priority: 60000
-
-# penalty indicates whether to apply penalty to update_every in case of failures.
-# Penalty will increase every 5 failed updates in a row. Maximum penalty is 10 minutes.
-# penalty: yes
-
-# autodetection_retry sets the job re-check interval in seconds.
-# The job is not deleted if check fails.
-# Attempts to start the job are made once every autodetection_retry.
-# This feature is disabled by default.
-# autodetection_retry: 0
-
-# ----------------------------------------------------------------------
-# JOBS (data collection sources)
-#
-# The default JOBS share the same *name*. 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.
-#
-# Any number of jobs is supported.
-#
-# All python.d.plugin JOBS (for all its modules) support a set of
-# predefined parameters. These are:
-#
-# job_name:
-# name: myname # the JOB's name as it will appear at the
-# # dashboard (by default is the job_name)
-# # JOBs sharing a name are mutually exclusive
-# update_every: 1 # the JOB's data collection frequency
-# priority: 60000 # the JOB's order on the dashboard
-# penalty: yes # the JOB's penalty
-# autodetection_retry: 0 # the JOB's re-check interval in seconds
-#
-# Additionally to the above, redis also supports the following:
-#
-# socket: 'path/to/redis.sock'
-#
-# or
-# host: 'IP or HOSTNAME' # the host to connect to
-# port: PORT # the port to connect to
-#
-# and
-# pass: 'password' # the redis password to use for AUTH command
-#
-
-# ----------------------------------------------------------------------
-# AUTO-DETECTION JOBS
-# only one of them will run (they have the same name)
