Log10 Loadshare (ESSENTIAL | 2024)

Notice how each order of magnitude increase in raw loadshare adds only to the log10 loadshare . This makes dashboards readable across a wide range. Practical Use Cases 1. Detecting "Hot Spots" in Load Balancer Pools Imagine you have an NGINX load balancer distributing traffic to 20 Node.js backends. The raw metrics show one server at 8,500 RPS and another at 1,200 RPS. The linear graph shows a tall spike and a flat line.

In distributed systems, loadshare represents the proportionate amount of traffic, computational work, or connection handles assigned to a specific node (server, container, or thread) relative to the total system capacity or total incoming requests. | Context | Definition of Loadshare | | :--- | :--- | | Load Balancer | The number of active connections or requests per second (RPS) routed to a single backend server. | | Message Queue | The number of unacknowledged messages a specific consumer is processing. | | Database Shard | The query throughput or data volume stored on a specific shard replica. | | CDN Edge Node | The bandwidth or request count handled by a particular Point of Presence (PoP). | log10 loadshare

# Extract RPS per backend from HAProxy logs (simplified) awk 'print $NF' /var/log/haproxy.log | sort | uniq -c | \ awk 'print "log10_loadshare=" log($1+1)/log(10) " raw=" $1' Raw loadshare tells you how much traffic a node handles, but not how well it handles it. A powerful composite metric is the Log-Load Latency Ratio (L3R) : Notice how each order of magnitude increase in
