GLIM

License: PRO+ (Professional Edition or higher)
Plugin Type: File Action
Author: Diskover Data, Inc.

Overview

The GLIM file action creates a seamless bridge between Diskover's powerful search capabilities and Telestream's GLIM media viewer. With a single click, users can locate media assets in Diskover and instantly stream them in GLIM for review—no manual path copying or application switching required.

GLIM (by Telestream) is a web-based media viewer designed for media and entertainment workflows. It enables teams to review dailies, annotate frames, and collaborate on video and image content without downloading large files to local workstations.

Key Features

• One-Click Streaming: Open any indexed media file directly in GLIM from Diskover search results

• Automatic Path Translation: Converts Diskover mount paths to GLIM's expected format behind the scenes

• Multi-Site Support: Configure different GLIM servers for different storage locations or production facilities

• Instant Response: Browser-based redirect with no background processing or wait times

• Worker-Aware Routing: Automatically routes files to the correct GLIM server based on which Diskover worker indexed them

Use Cases

For Production Teams and Artists

The ability to search content in Diskover and then easily stream it in GLIM is a critical workflow enhancement. Artists and production coordinators can search for specific shots, sequences, or assets using Diskover's metadata search, then immediately begin reviewing without navigating GLIM's file browser or copying file paths manually.

For Dailies Review

Teams reviewing dailies can browse through indexed folders in Diskover, opening files sequentially in GLIM. This is particularly valuable when reviewing work-in-progress content across multiple shots or sequences.

For Distributed Production Environments

Organizations with multiple facilities or storage systems benefit from the multi-worker configuration. Files indexed from different locations automatically open in the GLIM server that has access to that specific storage—users don't need to know which server to use.

Understanding GLIM Integration

GLIM uses its own path notation to reference files on connected storage. When Diskover indexes files, it records paths using the local mount point (e.g., /mnt/snfs3/projects/movie/shot001.mov). GLIM expects paths in a different format (e.g., ::SNFS3/projects/movie/shot001.mov).

The GLIM file action automatically translates between these formats using configurable path translation rules. This happens transparently—users simply click to open a file, and the correct GLIM path is constructed automatically.

Path Format Comparison

Understanding this translation is important for administrators configuring the file action, but end users don't need to worry about it during normal use.

Installation & Setup

Installation

The GLIM file action is installed via RPM package:

dnf install diskover-file-actions-glim

After installation, restart the required services:

# On the Diskover Web host
systemctl restart diskover-admin

# On all Diskover Task Worker host(s)
systemctl restart celery

Initial Configuration

1. Log into Diskover Admin

2. Navigate to Configuration > Plugins > File Actions > GLIM

3. Configure at least one GLIM host (see Configuration section below)

4. Save the configuration

Verify Setup

After configuration:

1. Navigate to any indexed media file in Diskover

2. Look for the eye icon in the file actions menu

3. Click the icon—your browser should redirect to GLIM with the file loaded

If the eye icon doesn't appear, verify that:

• The file action is enabled in Diskover Admin

• You have refreshed your browser after configuration changes

• Your user account has permission to use file actions

Configuration

Configuration is managed through the Diskover Admin interface at Configuration > Plugins > File Actions > GLIM.

Configuration Parameters

GLIM Host Configuration

Each entry in the glim_hosts list defines a GLIM server and its settings:

Path Translation Rules

Each path translation rule contains:

Important: Translation rules are processed in order, and the first matching rule is applied. Place more specific paths before general paths.

Configuration Examples

Single GLIM Server (Simple Setup)

For environments with one GLIM server serving all storage:

{
  "glim_hosts": [
    {
      "worker": "worker01",
      "host": "glim.example.com",
      "port": 443,
      "use_https": true,
      "path_translations": [
        {
          "from_path": "/mnt/snfs3",
          "to_path": "::SNFS3"
        },
        {
          "from_path": "/mnt/projects",
          "to_path": "::PROJECTS"
        }
      ]
    }
  ]
}

Multi-Site Configuration

For distributed environments with multiple GLIM servers:

{
  "glim_hosts": [
    {
      "worker": "worker-east",
      "host": "glim-east.example.com",
      "port": 443,
      "use_https": true,
      "path_translations": [
        {
          "from_path": "/mnt/snfs3",
          "to_path": "::SNFS3"
        }
      ]
    },
    {
      "worker": "worker-west",
      "host": "glim-west.example.com",
      "port": 443,
      "use_https": true,
      "path_translations": [
        {
          "from_path": "/mnt/nas1",
          "to_path": "::NAS1"
        }
      ]
    }
  ]
}

In this configuration:

• Files indexed by worker-east open in glim-east.example.com

• Files indexed by worker-west open in glim-west.example.com

• The first host serves as the default for any workers not explicitly listed

Usage Guide

Opening Files in GLIM

1. Search or Browse: Use Diskover to locate the media file you want to review

2. Select the File: Click on the file to select it

3. Launch GLIM: Click the eye icon in the file actions menu (or right-click for context menu)

4. View in GLIM: Your browser redirects to GLIM with the file ready for streaming

Workflow: Searching for Specific Content

This workflow is ideal when you know what you're looking for:

1. Enter search terms in Diskover (shot name, sequence number, asset type, etc.)

2. Review search results and locate the target file

3. Click the eye icon to stream the file in GLIM

4. Use GLIM's playback and annotation tools to review the content

Workflow: Browsing Dailies

This workflow works well for sequential review:

1. Navigate to the dailies folder in Diskover

2. Sort files by date, name, or other relevant criteria

3. Select the first file and click the eye icon

4. After reviewing in GLIM, return to Diskover and open the next file

Supported File Types

GLIM supports a wide range of media formats. Common supported types include:

For a complete list of supported formats, consult your GLIM documentation.

Working with Path Translation

When you open a file in GLIM, the path displayed will use GLIM's notation rather than the Diskover mount path:

This is expected behavior—the path translation ensures GLIM can locate the file on its connected storage.

Limitations

• Single File Operation: The GLIM file action opens one file at a time. When multiple files are selected, only the first file opens in GLIM.

• Browser Dependent: The redirect requires JavaScript to be enabled in your browser.

• Network Required: Your browser must be able to reach the configured GLIM server.

Troubleshooting

Common Issues

Verifying Worker Assignment

If files consistently open in the wrong GLIM server:

1. Enable debug mode (see below)

2. Click the GLIM action on a test file

3. Check the "Worker" field in the debug output

4. Compare the detected worker name with your glim_hosts configuration

5. Ensure worker names match exactly (case-sensitive)

Enabling Debug Mode

For detailed diagnostic information, enable debug mode in the file action handler:

File: /opt/diskover-web/public/fileactions/glim.php

Line 3: Change to:

$fileactions_debug = TRUE;

With debug mode enabled, clicking the GLIM action displays diagnostic information instead of redirecting:

• Session status and data

• Detected worker name

• Loaded configuration

• Selected host configuration

• Original and translated file paths

• Final constructed URL

Important: Set $fileactions_debug = FALSE; after troubleshooting to restore normal operation.

Debug Logging

For ongoing troubleshooting, check the following log files:

Set log level to DEBUG in configuration for more detailed output.

Testing Connectivity

If you suspect network issues between the user's browser and GLIM:

# Test HTTPS connectivity
curl -I https://glim.example.com/

# Test with custom port
curl -I https://glim.example.com:8443/

# Check DNS resolution
nslookup glim.example.com

# Test TCP connectivity
nc -zv glim.example.com 443
