-## Using the path instead of the query string
-
-The badges can also be generated using the URL path for passing parameters. The format is exactly the same.
-
-So instead of:
-
-  `http://your.netdata:19999/api/v1/badge.svg?option1&option2&option3&...`
-
-you can write:
-
-  `http://your.netdata:19999/api/v1/badge.svg/option1/option2/option3/...`
-
-You can also append anything else you like, like this:
-

+# Health API Calls
+
+## Health Read API
+
+### Enabled Alarms
+
+NetData enables alarms on demand, i.e. when the chart they should be linked to starts collecting data. So, although many more alarms are configured, only the useful ones are enabled.
+
+To get the list of all enabled alarms:
+
+`http://your.netdata.ip:19999/api/v1/alarms?all`
+
+### Raised Alarms
+
+This API call will return the alarms currently in WARNING or CRITICAL state.
+
+`http://your.netdata.ip:19999/api/v1/alarms`
+
+### Event Log
+
+The size of the alarm log is configured in `netdata.conf`. There are 2 settings: the rotation of the alarm log file and the in memory size of the alarm log.
+
+```
+[health]
+	in memory max health log entries = 1000
+	rotate log every lines = 2000
+```
+
+The API call retrieves all entries of the alarm log:
+
+`http://your.netdata.ip:19999/api/v1/alarm_log`
+
+### Alarm Log Incremental Updates
+
+`http://your.netdata.ip:19999/api/v1/alarm_log?after=UNIQUEID`
+
+The above returns all the events in the alarm log that occurred after UNIQUEID (you poll it once without `after=`, remember the last UNIQUEID of the returned set, which you give back to get incrementally the next events).

+### Alarm badges
+
+The following will return an SVG badge of the alarm named `NAME`, attached to the chart named `CHART`.
+
+`http://your.netdata.ip:19999/api/v1/badge.svg?alarm=NAME&chart=CHART`
+
+## 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.
+
+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.
+ - Silence alarm notifications. Alarm conditions will be evaluated, the alarms will appear in the log and the netdata UI will show the alarms as active, but no notifications will be sent.
+ - Disable or Silence specific alarms that match selectors on alarm/template name, chart, context, host and family. 
+
+The API is available by default, but it is protected by an `api authorization token` that is stored in the file you will see in the following entry of `http://localhost:19999/netdata.conf`:
+
+```bash
+[registry]
+    # netdata management api key file = /var/lib/netdata/netdata.api.key
+```
+
+You can access the API via GET requests, by adding the bearer token to an `Authorization` http header, like this: 
+
+```
+curl "http://myserver/api/v1/manage/health?cmd=RESET" -H "X-Auth-Token: Mytoken" 
+```
+
+The command `RESET` just returns netdata to the default operation, with all health checks and notifications enabled. 
+If you've configured and entered your token correclty, you should see the plain text response `All health checks and notifications are enabled`.
+
+### Disable or silence all alarms
+
+If all you need is temporarily disable all health checks, then you issue the following before your maintenance period starts:
+```
+curl "http://myserver/api/v1/manage/health?cmd=DISABLE ALL" -H "X-Auth-Token: Mytoken" 
+```
+The effect of disabling health checks is that the alarm criteria are not evaluated at all and nothing is written in the alarm log.
+If you want the health checks to be running but to not receive any notifications during your maintenance period, you can instead use this:
+
+```
+curl "http://myserver/api/v1/manage/health?cmd=SILENCE ALL" -H "X-Auth-Token: Mytoken" 
+```
+
+Alarms may then still be raised and logged in netdata, so you'll be able to see them via the UI.  
+
+Regardless of the option you choose, at the end of your maintenance period you revert to the normal state via the RESET command.
+
+```
+ curl "http://myserver/api/v1/manage/health?cmd=RESET" -H "X-Auth-Token: Mytoken" 
+```
+
+### Disable or silence specific alarms
+
+If you do not wish to disable/silence all alarms, then the `DISABLE ALL` and `SILENCE ALL` commands can't be used. 
+Instead, the following commands expect that one or more alarm selectors will be added, so that only alarms that match the selectors are disabled or silenced.  
+- `DISABLE` : Set the mode to disable health checks. 
+- `SILENCE` : Set the mode to silence notifications. 
+
+You will normally put one of these commands in the same request with your first alarm selector, but it's possible to issue them separately as well. 
+You will get a warning in the response, if a selector was added without a SILENCE/DISABLE command, or vice versa. 
+
+Each request can specify a single alarm `selector`, with one or more `selection criteria`. 
+A single alarm will match a `selector` if all selection criteria match the alarm. 
+You can add as many selectors as you like.
+In essence, the rule is: IF (alarm matches all the criteria in selector1 OR all the criteria in selector2 OR ...) THEN apply the DISABLE or SILENCE command.
+
+To clear all selectors and reset the mode to default, use the `RESET` command.
+
+The following example silences notifications for all the alarms with context=load: 
+
+```
+curl "http://myserver/api/v1/manage/health?cmd=SILENCE&context=load" -H "X-Auth-Token: Mytoken" 
+```
+
+#### Selection criteria 
+
+The `selection criteria` are key/value pairs, in the format `key : value`, where value is a netdata [simple pattern](../../../libnetdata/simple_pattern/). This means that you can create very powerful selectors (you will rarely need more than one or two). 
+
+The accepted keys for the `selection criteria` are the following:
+- `alarm`    : The expression provided will match both `alarm` and `template` names. 
+- `chart`    : Chart ids/names, as shown on the dashboard. These will match the `on` entry of a configured `alarm`.
+- `context`  : Chart context, as shown on the dashboard. These will match the `on` entry of a configured `template`.
+- `hosts`    : The hostnames that will need to match.
+- `families` : The alarm families.
+
+You can add any of the selection criteria you need on the request, to ensure that only the alarms you are interested in are matched and disabled/silenced. e.g. there is no reason to add `hosts: *`, if you want the criteria to be applied to alarms for all hosts. 
+
+Example 1: Disable all health checks for context = `random`
+
+```
+http://localhost/api/v1/manage/health?cmd=DISABLE&context=random
+```
+
+Example 2: Silence all alarms and templates with name starting with `out_of` on host `myhost`
+
+```
+http://localhost/api/v1/manage/health?cmd=SILENCE&alarm=out_of*&hosts=myhost
+```
+
+Example 2.2: Add one more selector, to also silence alarms for cpu1 and cpu2
+
+```
+http://localhost/api/v1/manage/health?families=cpu1 cpu2
+```
+
+### Responses
+
+- "Auth Error" : Token authentication failed
+- "All alarm notifications are silenced" : Successful response to cmd=SILENCE ALL
+- "All health checks are disabled" : Successful response to cmd=DISABLE ALL
+- "All health checks and notifications are enabled" : Successful response to cmd=RESET
+- "Health checks disabled for alarms matching the selectors" : Added to the response for a cmd=DISABLE
+- "Alarm notifications silenced for alarms matching the selectors" : Added to the response for a cmd=SILENCE
+- "Alarm selector added" : Added to the response when a new selector is added
+- "Invalid key. Ignoring it." : Wrong name of a parameter. Added to the response and ignored.
+- "WARNING: Added alarm selector to silence/disable alarms without a SILENCE or DISABLE command." : Added to the response if a selector is added without a selector-specific command.
+- "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.

 `after` and `before` to be a multiple of `group points`.

 The query engine is highly optimized for speed. Most of its modules implement "online"
 versions of the algorithms, requiring just one pass on the database values to produce
 the result.
+
+## Example
+
+When netdata is reducing metrics, it tries to return always the same boundaries. So, if we want 10s averages, it will always return points starting at a `unix timestamp % 10 = 0`.
+
+Let's see why this is needed, by looking at the error case.
+
+Assume we have 5 points:
+
+| time | value |
+| :-: | :-: |
+| 00:01 | 1 |
+| 00:02 | 2 |
+| 00:03 | 3 |
+| 00:04 | 4 |
+| 00:05 | 5 |
+
+At 00:04 you ask for 2 points for 4 seconds in the past. So `group = 2`. netdata would return:
+
+| point | time | value |
+| :-: | :-: | :-: |
+| 1 | 00:01 - 00:02 | 1.5 |
+| 2 | 00:03 - 00:04 | 3.5 |
+
+A second later the chart is to be refreshed, and makes again the same request at 00:05. These are the points that would have been returned:
+
+| point | time | value |
+| :-: | :-: | :-: |
+| 1 | 00:02 - 00:03 | 2.5 |
+| 2 | 00:04 - 00:05 | 4.5 |
+
+**Wait a moment!** The chart was shifted just one point and it changed value! Point 2 was 3.5 and when shifted to point 1 is 2.5! If you see this in a chart, it's a mess. The charts change shape constantly.
+
+For this reason, netdata always aligns the data it returns to the `group`.
+
+When you request `points=1`, netdata understands that you need 1 point for the whole database, so `group = 3600`. Then it tries to find the starting point which would be `timestamp % 3600 = 0` Within a database of 3600 seconds, there is one such point for sure. Then it tries to find the average of 3600 points. But, most probably it will not find 3600 of them (for just 1 out of 3600 seconds this query will return something).
+
+So, the proper way to query the database is to also set at least `after`. The following call will returns 1 point for the last complete 10-second duration (it starts at `timestamp % 10 = 0`):
+
+http://netdata.firehol.org/api/v1/data?chart=system.cpu&points=1&after=-10&options=seconds
+
+When you keep calling this URL, you will see that it returns one new value every 10 seconds, and the timestamp always ends with zero. Similarly, if you say `points=1&after=-5` it will always return timestamps ending with 0 or 5.

+        <div style="padding-bottom: 1em">
+            <p>
+                Netdata is a monitoring agent you install on all your systems:
+            <br/>
+                <b>physical servers</b>, <b>virtual servers</b>, <b>containers</b>, <b>IoT</b>.
+            </p>
+            <p>
+                Netdata is lightweight, designed to permanently run on all systems without disrupting their core function.
+                By default, it needs just 1% CPU of a single core, a few MB or RAM and no disk I/O at all.
+            </p>
+            <p>
+                Each Netdata is (by default) autonomous, taking care of all the following.
+                <br/>But all your Netdata are integrated into one large distributed application.
+            </p>
+        </div>
+        <div class=grid>
+            <div class=grid-cell><h3><span class=star>&#x2605;</span> Collect</h3>
+                <p>
+                    Netdata automatically detects data collection sources on the host it runs.
+                    It comes with hundreds of plugins for collecting system and application metrics,
+                    including databases, web servers, and commonly used application servers.
+                    <br/> <br/>
+                    Netdata is also a high performance, distributed <b>statsd server</b>, allowing custom
+                    application metrics to be collected and visualized.

+            <div class=grid-cell><h3><span class=star>&#x2605;</span> Check (alarms)</h3>
+                <p>
+                    Each Netdata spawns a thread that examines the metrics as they get collected,
+                    evaluates pre-configured alarm expressions and triggers alarm notifications.
+                    <br/> <br/>
+                    Netdata comes with hundreds of alarms to detect common system and application issues,
+                    that are automatically attached to the collected metrics,
+                    supporting dozens of alarm notification integrations.

+            <div class=grid-cell><h3><span class=star>&#x2605;</span> Stream</h3>
+                <p>
+                    Each Netdata can stream its metrics, in real-time, to any other Netdata.
+                    Streaming allows Netdata to be used in ephemeral nodes and containers in auto-scaled environments,
+                    but it also allows building Netdata hierarchies for aggregating the metrics of multiple Netdata nodes.

+                    and multiple readers per metric, concurrently, contributing significantly to
+                    the performance of Netdata.

+                <p>
+                    Netdata can archive its metrics to time-series databases (prometheus, graphite, opentsdb, json document dbs, etc)
+                    so that Netdata can be integrated to existing monitoring tool-chains.

+                    The best part of Netdata is its visualization. Low latency, speedy and snazzy.
+                    <br/> <br/>
+                    Netdata dashboards are optimized for visual anomaly detection, a powerful tool to troubleshoot

-Netdata supports 3 implementations of its internal web server:
-
-- `static-threaded` is a web server with a fix (configured number of threads)
-- `single-threaded` is a simple web server running with a single thread
-- `multi-threaded` is a web server that spawns a thread for each client connection
-- `none` to disable the web server
-
-We suggest to use the `static-threaded` one. It is the most efficient.

-All versions of the web servers use non-blocking I/O.

-All web servers respect the `keep-alive` HTTP header to serve multiple HTTP requests via the same connection.
+The Netdata web server runs as `static-threaded`, i.e. with a fixed, configurable number of threads.
+It uses non-blocking I/O and respects the `keep-alive` HTTP header to serve multiple HTTP requests via the same connection.

-The `static` web server supports also these settings:
+With the web server enabled, you can control the number of threads and sockets with the following settings:

-Netdata can bind to multiple IPs and ports. Up to 100 sockets can be used (you can increase it at compile time with `CFLAGS="-DMAX_LISTEN_FDS=200" ./netdata-installer.sh ...`).
+Netdata can bind to multiple IPs and ports, offering access to different services on each. Up to 100 sockets can be used (you can increase it at compile time with `CFLAGS="-DMAX_LISTEN_FDS=200" ./netdata-installer.sh ...`).
 
 The ports to bind are controlled via `[web].bind to`, like this:
 
 ```
 [web]
    default port = 19999
-   bind to = 127.0.0.1 10.1.1.1:19998 hostname:19997 [::]:19996 localhost:19995 *:http unix:/tmp/netdata.sock
+   bind to = 127.0.0.1=dashboard 10.1.1.1:19998=management|netdata.conf hostname:19997=badges [::]:19996=streaming localhost:19995=registry *:http=dashboard unix:/tmp/netdata.sock
 ```
 
 Using the above, netdata will bind to:
 
-- IPv4 127.0.0.1 at port 19999 (port was used from `default port`)
-- IPv4 10.1.1.1 at port 19998
-- All the IPs `hostname` resolves to (both IPv4 and IPv6 depending on the resolved IPs) at port 19997
-- All IPv6 IPs at port 19996
-- All the IPs `localhost` resolves to (both IPv4 and IPv6 depending the resolved IPs) at port 19996
-- All IPv4 and IPv6 IPs at port `http` as set in `/etc/services`
-- Unix domain socket `/tmp/netdata.sock`
+- IPv4 127.0.0.1 at port 19999 (port was used from `default port`). Only the UI (dashboard) and the read API will be accessible on this port. 
+- IPv4 10.1.1.1 at port 19998. The management API and netdata.conf will be accessible on this port.
+- All the IPs `hostname` resolves to (both IPv4 and IPv6 depending on the resolved IPs) at port 19997. Only badges will be accessible on this port.
+- All IPv6 IPs at port 19996. Only metric streaming requests from other netdata agents will be accepted on this port.
+- All the IPs `localhost` resolves to (both IPv4 and IPv6 depending the resolved IPs) at port 19996. This port will only accept registry API requests.
+- All IPv4 and IPv6 IPs at port `http` as set in `/etc/services`. Only the UI (dashboard) and the read API will be accessible on this port. 
+- Unix domain socket `/tmp/netdata.sock`. All requests are serviceable on this socket.
 
 The option `[web].default port` is used when an entries in `[web].bind to` do not specify a port.
 
+Note that the access permissions specified with the `=request type|request type|...` format are available from version 1.12 onwards. 
+As shown in the example above, these permissions are optional, with the default being to permit all request types on the specified port. 
+The request types are strings identical to the `allow X from` directives of the access lists, i.e. `dashboard`, `streaming`, `registry`, `netdata.conf`, `badges` and `management`. 
+The access lists themselves and the general setting `allow connections from` in the next section are applied regardless of the ports that are configured to provide these services. 
+The API requests are serviced as follows:
+- `dashboard` gives access to the UI, the read API and badges API calls.
+- `badges` gives access only to the badges API calls.
+- `management` gives access only to the management API calls.

-# `multi-threaded` web server
-
-The `multi-threaded` web server spawns a thread for each connection it receives.
-
-Each thread uses non-blocking I/O so it can serve any number of web requests in parallel,
-though this is not supported by HTTP, so in practice each thread serves all the requests sequentially.
-
-Each thread respects the `keep-alive` HTTP header to serve multiple HTTP requests via the same connection.

-# `single-threaded` web server
-
-The `single-threaded` web server runs as a single thread inside netdata.
-It uses non-blocking I/O so it can serve any number of web requests in parallel.
-
-This web server respects the `keep-alive` HTTP header to serve multiple HTTP requests via the same connection.
