+# Memcached monitoring with Netdata
+
+Collects memory-caching system performance metrics. It reads server response to stats command ([stats interface](https://github.com/memcached/memcached/wiki/Commands#stats)).
+
+
+1.  **Network** in kilobytes/s
+
+    -   read
+    -   written
+
+2.  **Connections** per second
+
+    -   current
+    -   rejected
+    -   total
+
+3.  **Items** in cluster
+
+    -   current
+    -   total
+
+4.  **Evicted and Reclaimed** items
+
+    -   evicted
+    -   reclaimed
+
+5.  **GET** requests/s
+
+    -   hits
+    -   misses
+
+6.  **GET rate** rate in requests/s
+
+    -   rate
+
+7.  **SET rate** rate in requests/s
+
+    -   rate
+
+8.  **DELETE** requests/s
+
+    -   hits
+    -   misses
+
+9.  **CAS** requests/s
+
+    -   hits
+    -   misses
+    -   bad value
+
+10. **Increment** requests/s
+
+    -   hits
+    -   misses
+
+11. **Decrement** requests/s
+
+    -   hits
+    -   misses
+
+12. **Touch** requests/s
+
+    -   hits
+    -   misses
+
+13. **Touch rate** rate in requests/s
+
+    -   rate
+
+## Configuration
+
+Edit the `python.d/memcached.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/memcached.conf
+```
+
+Sample:
+
+```yaml
+localtcpip:
+  name     : 'local'
+  host     : '127.0.0.1'
+  port     : 24242
+```
+
+If no configuration is given, module will attempt to connect to memcached instance on `127.0.0.1:11211` address.

+# netdata python.d.plugin configuration for memcached
+#
+# 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, memcached also supports the following:
+#
+#     socket: 'path/to/memcached.sock'
+#
+#  or
+#     host: 'IP or HOSTNAME' # the host to connect to
+#     port: PORT             # the port to connect to
+#
+#
+
+# ----------------------------------------------------------------------
+# AUTO-DETECTION JOBS
+# only one of them will run (they have the same name)
