Snippets Library

The Snippets Library provides reusable code templates and patterns for common LogicMonitor scripting tasks.

Accessing Snippets

Method	Action
Sidebar	Click Snippets tab in the right sidebar

Snippet Types

Templates

Complete script starters that replace your entire script content.

Use templates when:

• Starting a new script from scratch
• Learning standard script patterns
• Need a complete working example

Caution

Inserting a template replaces your current script content. A confirmation dialog appears.

Patterns

Code fragments that insert at your cursor position.

Use patterns when:

• Adding functionality to an existing script
• Inserting common boilerplate code
• Using standard coding patterns

Patterns are inserted without replacing existing content.

Creating Custom Snippets

1. Click Create Snippet in the panel

2. Fill in required fields:

   • Name: Unique identifier
   • Category: Organization category
   • Language: Groovy or PowerShell
   • Type: Template or Pattern
   • Content: The actual code

3. Optionally add description and tags

4. Click Save

Example Pattern

// SNMP Walk Pattern
// TODO: Set target OID
def baseOid = "1.3.6.1.2.1.2.2.1"
def host = hostProps.get("system.hostname")
def community = hostProps.get("snmp.community")

def results = Snmp.walk(host, community, baseOid)
results.each { oid, value ->
    println "${oid} = ${value}"
}

Managing Custom Snippets

Action	Description
Edit	Click the edit icon on your snippet, modify details, and save
Delete	Click the delete icon and confirm. Deleted snippets cannot be recovered.

Storage

Custom snippets are stored in browser local storage. They persist across sessions but are not synced between browsers/devices.

Snippet Organization

Naming Conventions

Use clear, descriptive names:

• SNMP_Walk_Interface_Stats
• HTTP_GET_With_Auth
• WMI_CPU_Query

Tags

Add relevant tags for searchability:

• Technology: snmp, wmi, http
• Purpose: discovery, collection
• Module type: datasource, configsource

---

Best Practices

• Create for Repeated Code — If you write similar code often, generalize it with placeholders and save as a snippet
• Maintain Your Library — Periodically review, update outdated snippets, and remove unused ones
• Document Your Snippets — Include what it does, required variables, expected output, and limitations
• Use TODO Markers — Add // TODO: comments where users need to customize the code

---

Snippet Workflow Example

Building a new DataSource:

1. Start with Basic DataSource template

2. Add SNMP Walk pattern for discovery

3. Add Instance Output pattern for AD formatting

4. Add SNMP Get pattern for collection

5. Customize for your specific use case
