Stream residue server logs via various hooks
npm install -g resitailsudo resitail --config <config>
Notice the sudo, this is because all the files written by residue server will need sudo access as they may be owned by one user or another with limited permissions. Resitail needs to be able to read all of these log files.
A configuration file looks like:
{
"residue_config" : "<residue-config>",
"hooks": [
... <see Connecting Hooks section below>
]
}
Hook is essentially a JS module with following minimal requirements
- A class with options constructor
- A send function with
dataparameter. - Export this class
Once connected resitail will use this send function to send the logs. A most commonly used hook is resitail-f.
Example:
"use strict";
function sampleHook (options) {
this.options = options;
this.send = (data) => {
console.log(data);
}
}
module.exports = (options) => new sampleHook(options);Data contains following properties:
| Property | Description |
|---|---|
event |
Event name (i.e, resitail:line, resitail:err) |
event_type |
Type of event (i.e, info, error) |
line |
Contents of event (either log line or error details etc) |
channel |
Type of channel (i.e, client or logger) |
channel_name |
Name of channel (i.e, client_id or logger_id) |
logger_id |
Logger ID if channel is client |
client_id |
Client ID if channel is logger |
Once hook is ready you can connect it by adding it to configuration.
{
"name": "<hook name>",
<path or package>
"enabled": false,
"config": {
"channels" : {
"to_client" : true,
"to_logger" : true
}
... more configs specific to hook
}
}
A fully working hook configuration looks like:
From registry (notice package and version):
{
"name": "resitail-f",
"package": "resitail-f",
"version": "latest"
"enabled": true,
"config": {
"channels" : {
"to_client" : true,
"to_logger" : true
}
port: 3000
}
}
This will install the package globally.
Local (notice path):
{
"name": "resitail-f",
"path": "../resitail-f",
"enabled": true,
"config": {
"channels" : {
"to_client" : true,
"to_logger" : true
}
port: 3000
}
}
