+
+## Overview
+
+Monitor Memcached metrics for proficient in-memory key-value store operations. Track cache hits, misses, and memory usage for efficient data caching.
+
+It reads server response to stats command ([stats interface](https://github.com/memcached/memcached/wiki/Commands#stats)).
+
+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
+
+If no configuration is given, collector will attempt to connect to memcached instance on `127.0.0.1:11211` address.
+
+
+#### 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 Memcached instance
+
+These metrics refer to the entire monitored application.
+
+This scope has no labels.
+
+Metrics:
+
+| Metric | Dimensions | Unit |
+|:------|:----------|:----|
+| memcached.cache | available, used | MiB |
+| memcached.net | in, out | kilobits/s |
+| memcached.connections | current, rejected, total | connections/s |
+| memcached.items | current, total | items |
+| memcached.evicted_reclaimed | reclaimed, evicted | items |
+| memcached.get | hints, misses | requests |
+| memcached.get_rate | rate | requests/s |
+| memcached.set_rate | rate | requests/s |
+| memcached.delete | hits, misses | requests |
+| memcached.cas | hits, misses, bad value | requests |
+| memcached.increment | hits, misses | requests |
+| memcached.decrement | hits, misses | requests |
+| memcached.touch | hits, misses | requests |
+| memcached.touch_rate | rate | requests/s |
+
+
+
+## Alerts
+
+
+The following alerts are available:
+
+| Alert name  | On metric | Description |
+|:------------|:----------|:------------|
+| [ memcached_cache_memory_usage ](https://github.com/netdata/netdata/blob/master/health/health.d/memcached.conf) | memcached.cache | cache memory utilization |
+| [ memcached_cache_fill_rate ](https://github.com/netdata/netdata/blob/master/health/health.d/memcached.conf) | memcached.cache | average rate the cache fills up (positive), or frees up (negative) space over the last hour |
+| [ memcached_out_of_cache_space_time ](https://github.com/netdata/netdata/blob/master/health/health.d/memcached.conf) | memcached.cache | estimated time the cache will run out of space if the system continues to add data at the same rate as the past hour |
+
+
+## Setup
+
+### Prerequisites
+
+No action required.
+
+### Configuration
+
+#### File
+
+The configuration file name for this integration is `python.d/memcached.conf`.
+
+
+You can edit the configuration file using the `edit-config` script from the
+Netdata [config directory](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md#the-netdata-config-directory).
+
+```bash
+cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
+sudo ./edit-config python.d/memcached.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.
+
+
+<details><summary>Config options</summary>
+
+| Name | Description | Default | Required |
+|:----|:-----------|:-------|:--------:|
+| host | the host to connect to. | 127.0.0.1 | no |
+| port | the port to connect to. | 11211 | no |
+| update_every | Sets the default data collection frequency. | 10 | no |
+| priority | Controls the order of charts at the netdata dashboard. | 60000 | no |
+| autodetection_retry | Sets the job re-check interval in seconds. | 0 | no |
+| penalty | Indicates whether to apply penalty to update_every in case of failures. | yes | no |
+| 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. |  | no |
+
+</details>
+
+#### Examples
+
+##### localhost
+
+An example configuration for localhost.
+
+```yaml
+localhost:
+  name: 'local'
+  host: 'localhost'
+  port: 11211
+
+```
+##### localipv4
+
+An example configuration for localipv4.
+
+<details><summary>Config</summary>
+
+```yaml
+localhost:
+  name: 'local'
+  host: '127.0.0.1'
+  port: 11211
+
+```
+</details>
+
+##### localipv6
+
+An example configuration for localipv6.
+
+<details><summary>Config</summary>
+
+```yaml
+localhost:
+  name: 'local'
+  host: '::1'
+  port: 11211
+
+```
+</details>
+
+
+
+## Troubleshooting
+
+### Debug Mode
+
+To troubleshoot issues with the `memcached` 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.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 `python.d.plugin` to debug the collector:
+
+  ```bash
+  ./python.d.plugin memcached debug trace
+  ```

+            * 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.
