# node.d.plugin
`node.d.plugin` is a Netdata external plugin. It is an **orchestrator** for data collection modules written in `node.js`.
1. It runs as an independent process `ps fax` shows it
2. It is started and stopped automatically by Netdata
3. It communicates with Netdata via a unidirectional pipe (sending data to the `netdata` daemon)
4. Supports any number of data collection **modules**
5. Allows each **module** to have one or more data collection **jobs**
6. Each **job** is collecting one or more metrics from a single data source
## Pull Request Checklist for Node.js Plugins
This is a generic checklist for submitting a new Node.js plugin for Netdata. It is by no means comprehensive.
At minimum, to be buildable and testable, the PR needs to include:
- The module itself, following proper naming conventions: `node.d/<module_dir>/<module_name>.node.js`
- A README.md file for the plugin.
- The configuration file for the module
- A basic configuration for the plugin in the appropriate global config file: `conf.d/node.d.conf`, which is also in JSON format. If the module should be enabled by default, add a section for it in the `modules` dictionary.
- A line for the plugin in the appropriate `Makefile.am` file: `node.d/Makefile.am` under `dist_node_DATA`.
- A line for the plugin configuration file in `conf.d/Makefile.am`: under `dist_nodeconfig_DATA`
- Optionally, chart information in `web/dashboard_info.js`. This generally involves specifying a name and icon for the section, and may include descriptions for the section or individual charts.
## Motivation
Node.js is perfect for asynchronous operations. It is very fast and quite common (actually the whole web is based on it).
Since data collection is not a CPU intensive task, node.js is an ideal solution for it.
`node.d.plugin` is a Netdata plugin that provides an abstraction layer to allow easy and quick development of data
collectors in node.js. It also manages all its data collectors (placed in `/usr/libexec/netdata/node.d`) using a single
instance of node, thus lowering the memory footprint of data collection.
Of course, there can be independent plugins written in node.js (placed in `/usr/libexec/netdata/plugins`).
These will have to be developed using the guidelines of **[External Plugins](/collectors/plugins.d/README.md)**.
To run `node.js` plugins you need to have `node` installed in your system.
In some older systems, the package named `node` is not node.js. It is a terminal emulation program called `ax25-node`.
In this case the node.js package may be referred as `nodejs`. Once you install `nodejs`, we suggest to link
`/usr/bin/nodejs` to `/usr/bin/node`, so that typing `node` in your terminal, opens node.js.
## configuring `node.d.plugin`
`node.d.plugin` can work even without any configuration. Its default configuration file is
`node.d.conf`. To edit it on your system, run `/etc/netdata/edit-config node.d.conf`.
## configuring `node.d.plugin` modules
`node.d.plugin` modules accept configuration in `JSON` format.
Unfortunately, `JSON` files do not accept comments. So, the best way to describe them is to have markdown text files
with instructions.
`JSON` has a very strict formatting. If you get errors from Netdata at `/var/log/netdata/error.log` that a certain
configuration file cannot be loaded, we suggest to verify it at <http://jsonlint.com/>.
The files in this directory, provide usable examples for configuring each `node.d.plugin` module.
## debugging modules written for node.d.plugin
To test `node.d.plugin` modules, which are placed in `/usr/libexec/netdata/node.d`, you can run `node.d.plugin` by hand,
like this:
```sh
# become user netdata
sudo su -s /bin/sh netdata
# run the plugin in debug mode
/usr/libexec/netdata/plugins.d/node.d.plugin debug 1 X Y Z
```
`node.d.plugin` will run in `debug` mode (lots of debug info), with an update frequency of `1` second, evaluating only
the collector scripts `X` (i.e. `/usr/libexec/netdata/node.d/X.node.js`), `Y` and `Z`.
You can define zero or more modules. If none is defined, `node.d.plugin` will evaluate all modules available.
Keep in mind that if your configs are not in `/etc/netdata`, you should do the following before running `node.d.plugin`:
```sh
export NETDATA_USER_CONFIG_DIR="/path/to/etc/netdata"
```
---
## developing `node.d.plugin` modules
Your data collection module should be split in 3 parts:
- a function to fetch the data from its source. `node.d.plugin` already can fetch data from web sources,
so you don't need to do anything about it for http.
- a function to process the fetched/manipulate the data fetched. This function will make a number of calls
to create charts and dimensions and pass the collected values to Netdata.
This is the only function you need to write for collecting http JSON data.
- a `configure` and an `update` function, which take care of your module configuration and data refresh
respectively. You can use the supplied ones.
Your module will automatically be able to process any number of servers, with different settings (even different
data collection frequencies). You will write just the work needed for one and `node.d.plugin` will do the rest.
For each server you are going to fetch data from, you will have to create a `service` (more later).
### writing the data collection module
To provide a module called `mymodule`, you have create the file `/usr/libexec/netdata/node.d/mymodule.node.js`, with this structure:
```js
// the processor is needed only
// if you need a custom processor
// other than http
netdata.processors.myprocessor = {
name: 'myprocessor',
process: function(service, callback) {
/* do data collection here */
callback(data);
}
};
// this is the mymodule definition
var mymodule = {
processResponse: function(service, data) {
/* send information to the Netdata server here */
},
configure: function(config) {
var eligible_services = 0;
if(typeof(config.servers) === 'undefined' || config.servers.length === 0) {
/*
* create a service using internal defaults;
* this is used for auto-detecting the settings
* if possible
*/
netdata.service({
name: 'a name for this service',
update_every: this.update_every,
module: this,
processor: netdata.processors.myprocessor,
// any other information your processor needs
}).execute(this.processResponse);
eligible_services++;
}
else {
/*
* create a service for each server in the
* configuration file
*/
var len = config.servers.length;
while(len--) {
var server = config.servers[len];
netdata.service({
name: server.name,
update_every: server.update_every,
module: this,
processor: netdata.processors.myprocessor,
// any other information your processor needs
}).execute(this.processResponse);
eligible_services++;
}
}
return eligible_services;
},
update: function(service, callback) {
/*
* this function is called when each service
* created by the configure function, needs to
* collect updated values.
*
* You normally will not need to change it.
*/
service.execute(function(service, data) {
mymodule.processResponse(service, data);
callback();
});
},
};
module.exports = mymodule;
```
#### configure(config)
`configure(config)` is called just once, when `node.d.plugin` starts.
The config file will contain the contents of `/etc/netdata/node.d/mymodule.conf`.
This file should have the following format:
```js
{
"enable_autodetect": false,
"update_every": 5,
"servers": [ { /* server 1 */ }, { /* server 2 */ } ]
}
```
If the config file `/etc/netdata/node.d/mymodule.conf` does not give a `enable_autodetect` or `update_every`, these
will be added by `node.d.plugin`. So you module will always have them.
The configuration file `/etc/netdata/node.d/mymodule.conf` may contain whatever else is needed for `mymodule`.
#### processResponse(data)
`data` may be `null` or whatever the processor specified in the `service` returned.
The `service` object defines a set of functions to allow you send information to the Netdata core about:
1. Charts and dimension definitions
2. Updated values, from the collected values

# SNMP device monitoring with Netdata
Collects data from any SNMP device and uses the [net-snmp](https://github.com/markabrahams/node-net-snmp) module.
It supports:
- all SNMP versions: SNMPv1, SNMPv2c and SNMPv3
- any number of SNMP devices
- each SNMP device can be used to collect data for any number of charts
- each chart may have any number of dimensions
- each SNMP device may have a different update frequency
- each SNMP device will accept one or more batches to report values (you can set `max_request_size` per SNMP server, to control the size of batches).
## Requirements
- `nodejs` minimum required version 4
## Configuration
You will need to create the file `/etc/netdata/node.d/snmp.conf` with data like the following.
In this example:
- the SNMP device is `10.11.12.8`.
- the SNMP community is `public`.
- we will update the values every 10 seconds (`update_every: 10` under the server `10.11.12.8`).
- we define 2 charts `snmp_switch.bandwidth_port1` and `snmp_switch.bandwidth_port2`, each having 2 dimensions: `in` and `out`. Note that the charts and dimensions must not contain any white space or special characters, other than `.` and `_`.
```json
{
"enable_autodetect": false,
"update_every": 5,
"max_request_size": 100,
"servers": [
{
"hostname": "10.11.12.8",
"community": "public",
"update_every": 10,
"max_request_size": 50,
"options": {
"timeout": 10000
},
"charts": {
"snmp_switch.bandwidth_port1": {
"title": "Switch Bandwidth for port 1",
"units": "kilobits/s",
"type": "area",
"priority": 1,
"family": "ports",
"dimensions": {
"in": {
"oid": "1.3.6.1.2.1.2.2.1.10.1",
"algorithm": "incremental",
"multiplier": 8,
"divisor": 1024,
"offset": 0
},
"out": {
"oid": "1.3.6.1.2.1.2.2.1.16.1",
"algorithm": "incremental",
"multiplier": -8,
"divisor": 1024,
"offset": 0
}
}
},
"snmp_switch.bandwidth_port2": {
"title": "Switch Bandwidth for port 2",
"units": "kilobits/s",
"type": "area",
"priority": 1,
"family": "ports",
"dimensions": {
"in": {
"oid": "1.3.6.1.2.1.2.2.1.10.2",
"algorithm": "incremental",
"multiplier": 8,
"divisor": 1024,
"offset": 0
},
"out": {
"oid": "1.3.6.1.2.1.2.2.1.16.2",
"algorithm": "incremental",
"multiplier": -8,
"divisor": 1024,
"offset": 0
}
}
}
}
}
]
}
```
`update_every` is the update frequency for each server, in seconds.
`max_request_size` limits the maximum number of OIDs that will be requested in a single call. The default is 50. Lower this number of you get `TooBig` errors in Netdata's `error.log`.
`family` sets the name of the submenu of the dashboard each chart will appear under.
`multiplier` and `divisor` are passed by the plugin to the Netdata daemon and are applied to the metric to convert it properly to `units`. For incremental counters with the exception of Counter64 type metrics, `offset` is added to the metric from within the SNMP plugin. This means that the value you will see in debug mode in the `DEBUG: setting current chart to... SET` line for a metric will not have been multiplied or divided, but it will have had the offset added to it.
<details markdown="1"><summary><b>Caution: Counter64 metrics do not support `offset` (issue #5028).</b></summary>
The SNMP plugin supports Counter64 metrics with the only limitation that the `offset` parameter should not be defined. Due to the way Javascript handles large numbers and the fact that the offset is applied to metrics inside the plugin, the offset will be ignored silently.
</details>
If you need to define many charts using incremental OIDs, you can use something like this:
```json
{
"enable_autodetect": false,
"update_every": 10,
"servers": [
{
"hostname": "10.11.12.8",
"community": "public",
"update_every": 10,
"options": {
"timeout": 20000
},
"charts": {
"snmp_switch.bandwidth_port": {
"title": "Switch Bandwidth for port ",
"units": "kilobits/s",
"type": "area",
"priority": 1,
"family": "ports",
"multiply_range": [
1,
24
],
"dimensions": {
"in": {
"oid": "1.3.6.1.2.1.2.2.1.10.",
"algorithm": "incremental",
"multiplier": 8,
"divisor": 1024,
"offset": 0
},
"out": {
"oid": "1.3.6.1.2.1.2.2.1.16.",
"algorithm": "incremental",
"multiplier": -8,
"divisor": 1024,
"offset": 0
}
}
}
}
}
]
}
```
This is like the previous, but the option `multiply_range` given, will multiply the current chart from `1` to `24` inclusive, producing 24 charts in total for the 24 ports of the switch `10.11.12.8`.
Each of the 24 new charts will have its id (1-24) appended at:
1. its chart unique id, i.e. `snmp_switch.bandwidth_port1` to `snmp_switch.bandwidth_port24`
2. its `title`, i.e. `Switch Bandwidth for port 1` to `Switch Bandwidth for port 24`
3. its `oid` (for all dimensions), i.e. dimension `in` will be `1.3.6.1.2.1.2.2.1.10.1` to `1.3.6.1.2.1.2.2.1.10.24`
4. its priority (which will be incremented for each chart so that the charts will appear on the dashboard in this order)
The `options` given for each server, are:
- `port` - UDP port to send requests too. Defaults to `161`.
- `retries` - number of times to re-send a request. Defaults to `1`.
- `sourceAddress` - IP address from which SNMP requests should originate, there is no default for this option, the operating system will select an appropriate source address when the SNMP request is sent.
- `sourcePort` - UDP port from which SNMP requests should originate, defaults to an ephemeral port selected by the operation system.
- `timeout` - number of milliseconds to wait for a response before re-trying or failing. Defaults to `5000`.
- `transport` - specify the transport to use, can be either `udp4` or `udp6`. Defaults to `udp4`.
- `version` - either `0` (v1) or `1` (v2) or `3` (v3). Defaults to `0`.
- `idBitsSize` - either `16` or `32`. Defaults to `32`. Used to reduce the size of the generated id for compatibility with some older devices.
## SNMPv3
To use SNMPv3:
- use `user` instead of `community`
- set `version` to 3
User syntax:
```json
{
"enable_autodetect": false,
"update_every": 10,
"servers": [
{
"hostname": "10.11.12.8",
"user": {
"name": "userName",
"level": 3,
"authProtocol": "3",
"authKey": "authKey",
"privProtocol": "2",
"privKey": "privKey"
},
"update_every": 10,
"options": {
"version": 3
},
"charts": {
}
}
]
}
```
Security levels (`level`):
- 1 is `noAuthNoPriv`
- 2 is `authNoPriv`
- 3 is `authPriv`
Authentication protocols (`authProtocol`):
- "1" is `none`
- "2" is `md5`
- "3" is `sha`
Privacy protocols (`privProtocol`):
- "1" is `none`
- "2" is `des`
For additional details please see [net-snmp module readme](https://github.com/markabrahams/node-net-snmp#snmpcreatev3session-target-user-options).
## Retrieving names from snmp
You can append a value retrieved from SNMP to the title, by adding `titleoid` to the chart.
You can set a dimension name to a value retrieved from SNMP, by adding `oidname` to the dimension.
Both of the above will participate in `multiply_range`.
## Testing the configuration
To test it, you can run:
```sh
/usr/libexec/netdata/plugins.d/node.d.plugin 1 snmp
```
The above will run it on your console and you will be able to see what Netdata sees, but also errors. You can get a very detailed output by appending `debug` to the command line.
If it works, restart Netdata to activate the snmp collector and refresh the dashboard (if your SNMP device responds with a delay, you may need to refresh the dashboard in a few seconds).
## Data collection speed
Keep in mind that many SNMP switches and routers are very slow. They may not be able to report values per second. If you run `node.d.plugin` in `debug` mode, it will report the time it took for the SNMP device to respond. My switch, for example, needs 7-8 seconds to respond for the traffic on 24 ports (48 OIDs, in/out).
Also, if you use many SNMP clients on the same SNMP device at the same time, values may be skipped. This is a problem of the SNMP device, not this collector.
## Finding OIDs
Use `snmpwalk`, like this:
```sh
snmpwalk -t 20 -v 1 -O fn -c public 10.11.12.8
```
- `-t 20` is the timeout in seconds
- `-v 1` is the SNMP version
- `-O fn` will display full OIDs in numeric format (you may want to run it also without this option to see human readable output of OIDs)
- `-c public` is the SNMP community
- `10.11.12.8` is the SNMP device
Keep in mind that `snmpwalk` outputs the OIDs with a dot in front them. You should remove this dot when adding OIDs to the configuration file of this collector.
## Example: Linksys SRW2024P
This is what I use for my Linksys SRW2024P. It creates:
1. A chart for power consumption (it is a PoE switch)
2. Two charts for packets received (total packets received and packets received with errors)
3. One chart for packets output
4. 24 charts, one for each port of the switch. It also appends the port names, as defined at the switch, to the chart titles.
This switch also reports various other metrics, like snmp, packets per port, etc. Unfortunately it does not report CPU utilization or backplane utilization.
This switch has a very slow SNMP processors. To respond, it needs about 8 seconds, so I have set the refresh frequency (`update_every`) to 15 seconds.

python is ideal for Netdata plugins. It is a simple, yet powerful way to collect data, it has a very small memory footprint, although it is not the most CPU efficient way to do it.
2. **node.js**, use `node.d.plugin`, there are a few examples in the [node.d
directory](/collectors/node.d.plugin/README.md)
node.js is the fastest scripting language for collecting data. If your plugin needs to do a lot of work, compute values, etc, node.js is probably the best choice before moving to compiled code. Keep in mind though that node.js is not memory efficient; it will probably need more RAM compared to python.

BASH is the simplest scripting language for collecting values. It is the less efficient though in terms of CPU resources. You can use it to collect data quickly, but extensive use of it might use a lot of system resources.

Of course, C is the most efficient way of collecting data. This is why Netdata itself is written in C.
