Using .Graph will filter the results to only include those that match the tagset for the alert. For instance an alert for os.low.memory{host=ny-web01} would only include series with the host=ny-web01 tags. If multiple series match then only the first matching result will be used. template graph.tem...

Using .GraphAll will include all the results in the graph. template graph.template { subject = ... body = `{{template "header" .}} <strong>GraphAll</strong> <div>{{.GraphAll .Alert.Vars.graph}}</div> <strong>GraphAll With Y Axis...

Graph queries can be defined inline if you don't want to use an Alert variable. template graph.template { subject = ... body = `{{template "header" .}} <strong>Graph With Inline Query</strong> <div>{{.Graph "q(\"avg:300s-avg:os.mem.perce...

When using GraphAll you may still want to filter the results, in which case you can use an Alert variable with the Filter, Sort, and Limit functions. template graph.template { subject = ... body = `{{template "header" .}} <strong>Graph Filtered Variable</strong...

public string Check() { string input = "Hello World!"; string pattern = @"W.rld"; // Hello Stack Overflow! return Regex.Replace(input, pattern, "Stack Overflow"); }

This uses the Dropbox Java SDK to create a shared link for a file at the Dropbox path /test.txt: try { SharedLinkMetadata sharedLinkMetadata = client.sharing().createSharedLinkWithSettings("/test.txt"); System.out.println(sharedLinkMetadata.getUrl()); } catch (CreateSharedLinkW...

This example uses the Dropbox .NET library to get a shared link for a file, either by creating a new one, or retrieving an existing one: SharedLinkMetadata sharedLinkMetadata; try { sharedLinkMetadata = await this.client.Sharing.CreateSharedLinkWithSettingsAsync (path); } catch (ApiException...

Git lets you use non-git commands and full sh shell syntax in your aliases if you prefix them with !. In your ~/.gitconfig file: [alias] temp = !git add -A && git commit -m "Temp" The fact that full shell syntax is available in these prefixed aliases also means you can us...

This lists all of the custom classifiers you have trained. 'use strict'; let watson = require('watson-developer-cloud'); var visualRecognition = watson.visual_recognition({ version: 'v3', api_key: process.env['API_KEY'], version_date:'2016-05-19' }); let url = "https://upl...

This returns information about a specific classifier ID you have trained. This includes information about its current status (i.e., if it is ready or not). 'use strict'; let watson = require('watson-developer-cloud'); var visualRecognition = watson.visual_recognition({ version: 'v3', ap...

Training a custom classifier requires a corpus of images organized into groups. In this example, I have a bunch of images of apples in one ZIP file, a bunch of images of bananas in another ZIP file, and a third group of images of things that are not fruits for a negative set. Once a custom classif...

'use strict'; let watson = require('watson-developer-cloud'); let fs = require('fs'); var visualRecognition = watson.visual_recognition({ version: 'v3', api_key: process.env.API_KEY, version_date:'2016-05-19' }); let classifier_id_to_delete = 'TheNameofMyClassifier_485506080'; ...

Prerequisites First, you have to install the watson-developer-cloud SDK. $ npm install watson-developer-cloud Classify an image URL We'll use an image of Captain America from Wikipedia. 'use strict'; let watson = require('watson-developer-cloud'); var visualRecognition = watson.visual...

The following examples use the Item Sales and Customers sample databases. Note: The BETWEEN operator is inclusive. Using the BETWEEN operator with Numbers: SELECT * From ItemSales WHERE Quantity BETWEEN 10 AND 17 This query will return all ItemSales records that have a quantity that is gr...

The examples below fill in a PhoneNumber for any Employee who is also a Customer and currently does not have a phone number set in the Employees Table. (These examples use the Employees and Customers tables from the Example Databases.) Standard SQL Update using a correlated subquery: UPDATE ...

Scollector binaries for Windows, Mac, and Linux are available from the Bosun release page and can be saved to /opt/scollector/ or C:\Program Files\scollector\. The Scollector configuration file uses TOML v0.2.0 to specify various settings and defaults to being named scollector.toml in the same folde...

On Windows you can install Scollector as a service using the -winsvc="install" flag. On Mac and Linux you must manually create a service or init script. For example here is a basic systemd unit file: #Scollector unit file saved to /etc/systemd/system/scollector.service [Unit] Descriptio...

#Example of a PowerShell external collector. See http://bosun.org/scollector/external-collectors for details #This file should be saved in C:\Program Files\scollector\collectors\0\mymetrics.ps1 since it is a continuous output script #scollector.toml should have ColDir = 'C:\Program Files\scollecto...

The following can be saved as main.go. After you update the EDITME settings and build the executable it can be used as a continuous external collector. package main import ( "fmt" "log" "net/url" "strconv" "time" &...

Scollector will monitor Linux processes specified in the configuration file. [[Process]] Command = "/opt/bosun/bosun" Name = "bosun" [[Process]] Command = "ruby" Name = "puppet-agent" Args = "puppet" [[Process]] Command = &qu...
