    Why monitor Varnish?

    Varnish Cache is a powerful HTTP accelerator used to dramatically speed up web applications. Monitoring Varnish is critical to ensure high cache hit ratios, detect backend failures, track object evictions, and maintain optimal performance for your content delivery.

    Metrics

    What we monitor

    Cache Hit Ratio

    Percentage of requests served from cache.

    Backend Health

    Health status of origin servers.

    Object Evictions

    Rate of objects evicted from cache.

    Requests/sec

    Total request throughput.

    Thread Pool Usage

    Active threads vs available.

    Backend Connections

    Connections to origin servers.

    Cache Size

    Current cached object storage usage.

    Ban List Length

    Number of active cache bans.

    Triggers & Alerts

    Configurable alert triggers

    Set up custom triggers in your dashboard to get notified the moment Varnish metrics cross your defined thresholds.

    Cache Hit Ratio

    warning

    Fires when hit ratio drops below threshold.

    Backend Down

    critical

    Alerts when a backend server fails health checks.

    Object Evictions

    warning

    Triggers on high eviction rate indicating cache pressure.

    Thread Pool

    critical

    Fires when thread pool is exhausted.

    Request Rate

    warning

    Alerts on unusual request throughput.

    Importance of Varnish Monitoring

    Varnish Cache can serve content 300x faster than origin servers. Without monitoring, cache misses and backend failures negate these benefits.

    • Maintain high cache hit ratios for optimal speed
    • Detect backend failures immediately
    • Track evictions to right-size cache storage
    • Monitor thread pools to prevent request drops
