 ## Health Management API
 
 Netdata v1.12 and beyond provides a command API to control health checks and notifications at runtime. The feature is especially useful for maintenance periods, during which you receive meaningless alarms.
+From Netdata v1.16.0 and beyond, the configuration controlled via the API commands is [persisted across netdata restarts](#persistence).
 
 Specifically, the API allows you to:
  - Disable health checks completely. Alarm conditions will not be evaluated at all and no entries will be added to the alarm log.

+### List silencers
+
+The command `LIST` was added in netdata v1.16.0 and returns a JSON with the current status of the silencers.
+
+```
+ curl "http://myserver/api/v1/manage/health?cmd=LIST" -H "X-Auth-Token: Mytoken"

+As an example, the following response shows that we have two silencers configured, one for an alarm called `samplealarm` and one for alarms with context `random` on host `myhost`

 - "WARNING: SILENCE or DISABLE command is ineffective without defining any alarm selectors." : Added to the response if a selector-specific command is issued without a selector.
 
+### Persistence
+
+From netdata v1.16.0 and beyond, the silencers configuration is persisted to disk and loaded when netdata starts.
+The JSON string returned by the [LIST command](#list-silencers) is automatically saved to the `silencers file`, every time a command alters the silencers configuration.
+The file's location is configurable in `netdata.conf`. The default is shown below:
+
+```
+[health]
+        # silencers file = /var/lib/netdata/health.silencers.json
+```

 The test script under [tests/health_mgmtapi](../../../tests/health_mgmtapi) contains a series of tests that you can either run or read through to understand the various calls and responses better.

+### Enabling TLS support
+
+
+Netdata since version 1.16 supports encrypted HTTP connections to the web server and encryption of the data stream between a slave and a master. 
+Inbound unix socket connections are unaffected, regardless of the SSL settings.  
+To enable SSL, provide the path to your certificate and private key in the `[web]` section of `netdata.conf`:
+
+```
+[web]
+	ssl key = /etc/netdata/ssl/key.pem
+	ssl certificate = /etc/netdata/ssl/cert.pem
+```
+
+Both files must be readable by the netdata user. If any of the two files does not exist or is unreadable, Netdata falls back to HTTP.
+
+For a master/slave connection, only the master needs these settings.
+
+For test purposes, you can generate self-signed certificates with the following command:
+
+```
+$ openssl req -newkey rsa:2048 -nodes -sha512 -x509 -days 365 -keyout key.pem -out cert.pem
+```
+
+TIP: If you use 4096 bits for the key and the certificate, netdata will need more CPU to process the whole communication. 
+rsa4096 can be until 4 times slower than rsa2048, so we recommend using 2048 bits. You can verify the difference by running
+
+```
+$ openssl speed rsa2048 rsa4096
+```
+
+#### SSL enforcement
+
+When the certificates are defined and unless any other options are provided, a Netdata server will:
+- Redirect all incoming HTTP web server requests to HTTPS. Applies to the dashboard, the API, netdata.conf and badges.
+- Allow incoming slave connections to use both unencrypted and encrypted communications for streaming.
+ 
+To change this behavior, you need to modify the `bind to` setting in the `[web]` section of `netdata.conf`.
+At the end of each port definition, you can append `^SSL=force` or `^SSL=optional`. What happens with these settings differs, depending on whether the port is used for HTTP/S requests, or for streaming.
+
+SSL setting | HTTP requests | HTTPS requests | Unencrypted Streams | Encrypted Streams 
+:------:|:-----:|:-----:|:-----:|:-------- 
+none | Redirected to HTTPS | Accepted | Accepted | Accepted
+`force` | Redirected to HTTPS | Accepted | Denied | Accepted
+`optional` | Accepted | Accepted | Accepted | Accepted
+
+Example:
+
+```
+[web]
+    bind to = *=dashboard|registry|badges|management|streaming|netdata.conf^SSL=force
+```
+
+For information how to configure the slaves to use TLS, check [securing the communication](../../streaming#securing-the-communication) in the streaming documentation.
+You will find there additional details on the expected behavior for client and server nodes, when their respective SSL options are enabled.
+
+#### SSL error
+
+It is possible that when you start to use the Netdata with SSL some erros will be register in the logs, this happens due possible incompatibilities between the browser options related to SSL like Ciphers and TLS/SSL version and the Netdata internal configuration. The most common error would be `error:00000006:lib(0):func(0):EVP lib`. In a near future the Netdata will allow our users to change the internal configuration to avoid errors like this, but until there we are setting the most common and safety options to the communication.
