**Netdata badges are powerful**!
-Given that netdata collects from **1.000** to **5.000** metrics per server (depending on the number of network interfaces, disks, cpu cores, applications running, users logged in, containers running, etc) and that netdata already has data reduction/aggregation functions embedded, the badges can be quite powerful.

For each metric/dimension and for arbitrary time-frames badges can show **min**, **max** or **average** value, but also **sum** or **incremental-sum** to have their **volume**.

-The right one is a **volume** calculation. Netdata calculated the total of the last 86.400 seconds (a day) which gives `kilobits`, then divided it by 8 to make it KB, then by 1024 to make it MB and then by 1024 to make it GB. Calculations like this are quite accurate, since for every value collected, every second, netdata interpolates it to second boundary using microsecond calculations.

## FAQ
#### Is it fast?
-On modern hardware, netdata can generate about **2.000 badges per second per core**, before noticing any delays. It generates a badge in about half a millisecond!
-Of course these timing are for badges that use recent data. If you need badges that do calculations over long durations (a day, or more), timing will differ. netdata logs its timings at its `access.log`, so take a look there before adding a heavy badge on a busy web site. Of course, you can cache such badges or have a cron job get them from netdata and save them at your web server at regular intervals.

+Using these options, any Netdata data query can instruct the web browser to download
the result and save it under a given filename.
For example, to download a CSV file with CPU utilization of the last hour,
[click here](https://registry.my-netdata.io/api/v1/data?chart=system.cpu&after=-3600&format=csv&options=nonzero&tqx=outFileName:system+cpu+utilization+of+the+last_hour.csv).
-
This is done by appending `&tqx=outFileName:FILENAME` to any data query.
The output will be in the format given with `&format=`.

+| `csvjsonarray`|application/json|a JSON array, with each row as another array (the first row has the dimension names)|
+| `tsv`|text/plain|like `csv` but TAB is used instead of comma to separate values (MS Excel flavor)|
+| `html`|text/html|an html table|
+| `markdown`|text/plain|markdown table|
In all formats the date and time is the first column.
The CSV formatter respects the following API `&options=`:
-option|supported|description
-:---:|:---:|:---
-`nonzero`|yes|to return only the dimensions that have at least a non-zero value
-`flip`|yes|to return the rows older to newer (the default is newer to older)
-`seconds`|yes|to return the date and time in unix timestamp
-`ms`|yes|to return the date and time in unit timestamp as milliseconds
-`percent`|yes|to replace all values with their percentage over the row total
-`abs`|yes|to turn all values positive
-`null2zero`|yes|to replace gaps with zeros (the default prints the string `null`

and [health monitoring queries](../../../../health).

## 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.

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:
-```
+```sh
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:
-```
+```sh
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.

-`options`|no|A bitmap of options that can affect the operation of the query. Only 2 options are used by the query engine: `unaligned` and `percentage`. All the other options are used by the output formatters. The default is to return aligned data.

## Operation
@@ -23,22 +23,22 @@ The query engine works as follows (in this order):
`after` and `before` define a time-frame, accepting:
-- **absolute timestamps** (unix timestamps, i.e. seconds since epoch).
+- **absolute timestamps** (unix timestamps, i.e. seconds since epoch).
-- **relative timestamps**:
+- **relative timestamps**:
- `before` is relative to now and `after` is relative to `before`.

+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:

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`.
+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).

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.

This szenario is useful if you have metrics that change only within a specific range, e.g. temperatures that are very unlikely to fall out of range. In these cases it is more useful to have the chart render the values between the given min and max, to better highlight the changes within them.

### Data points
For the time-frame requested, `dashboard.js` will use the chart dimensions and the settings of the chart library to find out how many data points it can show.
-For example, most line chart libraries are using 3 pixels per data point. If the chart shows 10 minutes of data (600 seconds), its update frequency is 1 second, and the chart width is 1800 pixels, then `dashboard.js` will request from the netdata server: 10 minutes of data, represented in 600 points, and the chart will be refreshed per second. If the user resizes the window so that the chart becomes 600 pixels wide, then `dashboard.js` will request the same 10 minutes of data, represented in 200 points and the chart will be refreshed once every 3 seconds.

### Enabling TLS support
Since v1.16.0, Netdata supports encrypted HTTP connections to the web server, plus encryption of streaming data between a slave and its master, via the TLS 1.2 protocol.
-Inbound unix socket connections are unaffected, regardless of the TLS settings.
+Inbound unix socket connections are unaffected, regardless of the TLS settings.\
??? info "Differences in TLS and SSL terminology"
While Netdata uses Transport Layer Security (TLS) 1.2 to encrypt communications rather than the obsolete SSL protocol, it's still common practice to refer to encrypted web connections as `SSL`. Many vendors, like Nginx and even Netdata itself, use `SSL` in configuration files, whereas documentation will always refer to encrypted communications as `TLS` or `TLS/SSL`.
To enable TLS, provide the path to your certificate and private key in the `[web]` section of `netdata.conf`:
-``` conf
+```conf
[web]
ssl key = /etc/netdata/ssl/key.pem
ssl certificate = /etc/netdata/ssl/cert.pem
@@ -77,31 +78,31 @@ Both files must be readable by the `netdata` user. If either of these files do n
For test purposes, you can generate self-signed certificates with the following command:
-``` bash
+```bash
$ openssl req -newkey rsa:2048 -nodes -sha512 -x509 -days 365 -keyout key.pem -out cert.pem
```
!!! note
If you use 4096 bits for your key and the certificate, Netdata will need more CPU to process the communication. `rsa4096` can be up to 4 times slower than `rsa2048`, so we recommend using 2048 bits. You can verify the difference by running:
-
- ```
- $ openssl speed rsa2048 rsa4096
- ```
+
+```sh
+$ openssl speed rsa2048 rsa4096
+```
#### TLS/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.
-
+- 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.

-If you publish your netdata to the internet, you may want to apply some protection against DDoS:
-
-1. Use the `static-threaded` web server (it is the default)
-2. Use reasonable `[web].web server max sockets` (the default is)
-3. Don't use all your cpu cores for netdata (lower `[web].web server threads`)
-4. Run netdata with a low process scheduling priority (the default is the lowest)
-5. If possible, proxy netdata via a full featured web server (nginx, apache, etc)
