Articles about Linux server monitoring, performance, and product updates.
LSI MegaRAID and Dell PERC controllers log critical thermal events to /proc that predict failures weeks before SMART data shows problems. Here's how to monitor them.
Read more →Reserved instance utilisation below 70% reveals sizing problems. Here's how pattern detection monitoring exposed €4,800 in hidden AWS costs.
Read more →Monitor DNS resolver behaviour through socket statistics to detect cache poisoning and performance issues without continuous dig queries impacting production.
Read more →Learn how to measure iptables rule processing overhead using kernel statistics, establishing performance baselines before firewall complexity degrades server response.
Read more →Monitor MySQL replication health through network socket analysis instead of SHOW SLAVE STATUS queries, detecting lag earlier without database performance impact.
Read more →Modern dual-stack networks hide IPv6 failures behind silent IPv4 fallbacks. Here's how to catch neighbour discovery issues before they impact performance.
Read more →Learn to monitor Apache performance through filesystem metrics when mod_status is disabled, using /proc to track connections and worker processes reliably.
Read more →Learn how to monitor Redis memory fragmentation using /proc filesystem analysis to avoid the performance overhead of Redis INFO commands while tracking jemalloc patterns.
Read more →A Python web app hit file descriptor exhaustion at 70% ulimit due to TIME_WAIT MySQL socket accumulation that standard monitoring completely missed.
Read more →Build PostgreSQL memory monitoring that detects exhaustion before performance degrades using system-level metrics instead of database queries.
