Why Continuous Monitoring Matters for Digital Collection Health

Learn why proactive monitoring is vital for maintaining fast, reliable, and secure digital archive collections—and how it supports long-term accessibility.

Digitising a historical collection is a significant achievement, but making it available online is only the beginning. Libraries, archives and cultural heritage organisations must also ensure their collections remain accessible, reliable and responsive over time.

Continuous monitoring provides visibility into system performance, resource use and emerging problems. It allows technical teams to identify and address issues before they significantly affect researchers or prevent organisations from adding new collection material.

Why does continuous monitoring matter for digital collections?

Once a historical collection is available online, researchers, students and members of the public expect it to remain accessible. However, performance issues can gradually develop even when the collection appears to be operating normally.

Inefficient memory use, growing data volumes, database bottlenecks and automated bot activity can place increasing pressure on the system. This may result in slower searches, delayed page loading or intermittent access problems.

Continuous monitoring acts as an ongoing health check. It helps technical teams identify unusual activity, declining performance and resources approaching their limits so they can investigate before users are significantly affected.

What digital collection metrics should be monitored?

The metrics monitored will depend on the platform and hosting environment, but commonly include:

• How efficiently the system is using memory. Think of memory as the ‘working space’ that allows searches and pages to load smoothly. Your IT team may refer to this as RAM usage.
• How quickly the system retrieves search results from the collection’s database — the underlying store of digitised content.
  Your IT team may refer to this as database query performance or query response time.
• How well the system responds under heavy use. For example, when many visitors are on the site at once.
  Your IT team may refer to CPU and I/O performance.
• How reliably and quickly pages load for visitors.
  Your IT team may refer to this as web request latency and error rates.
• Storage or page capacity nearing limits. This can affect how much new content can be added to the collection.
  Your IT team may refer to this as disk space utilisation.
• SSL certificates approaching expiration. SSL certificates ensure your site’s secure connection; if they expire, users may see browser security warnings.
• Memory or disk space constraints during peak use. These can slow searches and page loading.
  Your IT team may refer to this as resource saturation or I/O bottlenecks.

What problems can continuous monitoring identify?

Continuous monitoring can identify performance bottlenecks, unusual traffic, increasing error rates, resource constraints and certificates approaching expiration.

In one case, Veridian’s monitoring detected a sudden surge in automated requests repeatedly accessing a collection. Identifying the activity early allowed our team to respond before it caused noticeable performance or access problems for users.

In another case, monitoring showed that a collection’s system was working harder than expected during busy periods. This early warning allowed us to refine how memory was being used, improving the collection’s speed and stability.

How does continuous monitoring support broader collection goals?

Beyond keeping your digital collection healthy, continuous monitoring helps libraries achieve broader, more strategic, goals:

• Automated monitoring frees internal teams to focus on digitisation, collection curation and community engagement.
• Reliable access and responsive performance strengthen confidence among researchers and other collection users.
• Monitoring provides internal stakeholders with assurance that the collection is being actively and responsibly managed.
• Early identification of capacity constraints supports planning for future collection growth.
• Performance and usage information can help organisations make informed decisions about infrastructure and ongoing investment.
  
  

How does Veridian monitor digital collection health?

For collections hosted and supported by Veridian, our team uses automated monitoring to track system availability, resource use, performance and unusual activity. Alerts help us investigate emerging issues and determine whether technical changes, additional resources or security controls are required.

Monitoring is supported by ongoing maintenance, software updates and technical oversight. Together, these practices help collections remain reliable as content volumes, user numbers and access patterns change.
