    Pourquoi surveiller ? Memcached?

    Memcached est un système de mise en cache en mémoire distribué et hautement performant, utilisé pour accélérer les applications web dynamiques en réduisant la charge pesant sur la base de données. La surveillance de Memcached garantit une utilisation optimale du cache, détecte les « tempêtes d'éviction » et empêche l'épuisement de la mémoire au sein de votre couche de mise en cache.

    Auto-discovery via Xitogent — no manual configuration required
    Real-time memory usage and allocation metrics
    Track hit/miss ratios and cache effectiveness
    Monitor active connections and connection rates
    Eviction rate and slab utilization tracking
    Items stored and reclaimed monitoring
    Works on both Linux and Windows servers
    1-minute metric collection intervals
    Indicateurs

    Ce que nous moniteur

    Used Memory

    Total memory currently allocated for cached items.

    Max Memory

    Maximum memory limit configured for the Memcached instance.

    Hit Rate

    Percentage of successful cache lookups vs misses, indicating cache effectiveness.

    Evictions

    Number of items evicted to make room for new data.

    Current Connections

    Number of currently open client connections.

    Items Stored

    Total number of items currently stored in cache.

    Get/Set Ratio

    Ratio of get to set commands, indicating read/write balance.

    Bytes Read/Written

    Total network throughput for the Memcached instance.

    CAS Hits/Misses

    Check-and-set operation success rates for concurrent updates.

    Slab Utilization

    Memory allocation efficiency across slab classes.

    Déclencheurs et alertes

    Configurable déclencheurs d'alerte

    Configurez des déclencheurs personnalisés dans votre tableau de bord pour être averti dès que les indicateurs d{name}s dépassent les seuils que vous avez définis.

    Memcached tableau de bord de configuration des déclencheurs de surveillance

    Memory Usage

    crucial

    Fires when Memcached memory consumption approaches the configured limit, risking evictions.

    Hit Rate Drop

    avertissement

    Alerts when cache hit rate drops below threshold, indicating cache inefficiency or working set changes.

    Eviction Rate

    crucial

    Fires when eviction rate spikes, meaning Memcached is actively removing data to stay within memory limits.

    Connection Count

    avertissement

    Triggers when client connections exceed the threshold, indicating potential connection leaks.

    Items Reclaimed

    avertissement

    Alerts when expired items are being reclaimed at a high rate, suggesting TTL misconfiguration.

    Importance of Memcached Monitoring

    Memcached silently powers your application's performance layer. Without monitoring, memory exhaustion, eviction storms, and connection leaks can degrade your entire application stack before anyone notices.

    • Detect memory pressure before evictions impact application performance
    • Monitor cache hit rates to ensure optimal response times
    • Track eviction patterns to right-size your memory allocation
    • Identify connection leaks from application clients
    • Ensure consistent cache performance across distributed nodes
