Stop relying on basic ping checks. In this deep dive, we explore how to build a scalable monitoring stack using Zabbix 2.4 and Graphite on high-performance KVM architecture, specifically tailored for the Norwegian market's latency and compliance demands.
Stop relying on load averages and ping checks. Learn how to monitor CPU steal, I/O wait, and Nginx throughput using Zabbix and custom Bash scripts on CentOS 7, specifically tailored for the Norwegian hosting market.
Nagios says your server is online, but your users are seeing 504 errors. In this 2014 guide, we dismantle the 'green light' fallacy, explore the emerging ELK stack for deep system introspection, and discuss why high-IOPS storage is non-negotiable for logging infrastructure in Norway.
The 'Cloud' promised efficiency, but your monthly bill says otherwise. Here is how to audit your stack, tune your kernel, and why raw I/O performance on Norwegian soil beats a bloated AWS instance every time.
Monitoring tells you the server is up. Deep diagnostics tell you why the database locks up every Tuesday at 14:00. A 2014 guide to moving from passive checks to active insight on Norwegian infrastructure.
Nagios tells you the server is up. It doesn't tell you why the checkout takes 5 seconds. Here is how to implement real Application Performance Monitoring on a Linux VPS without breaking the bank.
Nagios says your server is UP, but your customers are seeing 504 Gateway Timeouts. In the wake of Heartbleed, we explore deep system introspection using Graphite, Logstash, and strace to find the bottlenecks that simple monitoring misses.
In 2014, a 'UP' status isn't enough. Learn why traditional port checks fail to detect application degradation and how to implement deep metric collection using Graphite, Logstash, and KVM-based introspection on Norwegian infrastructure.
Is your server actually healthy, or is it just responding to ping? We dissect the critical shift from binary monitoring to deep system visibility using Graphite, Logstash, and the right underlying infrastructure.
It is June 2013. The PRISM scandal is fresh, and your Nagios dashboard says 'OK', but customers are churning. We dissect the difference between standard monitoring and deep system introspection using Graphite, StatsD, and Logstash on high-performance KVM architecture.
Stop guessing why your server is slow. From mastering `strace` to leveraging SSD I/O, we dive deep into diagnosing bottlenecks on Linux systems in the Norwegian hosting landscape.
Is your server actually healthy, or is it just responding to ping? In 2013, Nagios isn't enough. We dive deep into system instrumentation, high-frequency metrics with Graphite, and why reliable SSD I/O is critical for logging stacks in the Nordic market.
Nagios alerts at 3 AM are not a monitoring strategy. Learn how to pinpoint bottlenecks in PHP, MySQL, and Disk I/O using tools like New Relic, iostat, and Nginx stub_status to stabilize your infrastructure.
Is your Nagios dashboard all green while your users see 504 errors? In 2013, 'up' is not enough. We explore the transition from binary monitoring to deep system metrics using Graphite, Logstash, and high-performance SSD VPS infrastructure.
Is your server 'up' but your users seeing 502s? Discover the difference between basic status checks and deep system metrics in 2013. We dive into Graphite, Collectd, and why hardware isolation matters for accurate data.
Load average is a vanity metric. In this deep dive, we explore how to actually debug latency in 2013 using iostat, MySQL slow logs, and proper Nginx profiling on high-performance SSD infrastructure.
Nagios alerts are useless if your disk I/O is choking. A battle-hardened look at monitoring high-load systems in 2013, why OpenVZ lies to you about load, and how to configure Zabbix and Munin for true visibility.
It is 2013, and ping checks are no longer enough. We explore the shift from basic monitoring to deep system introspection using StatsD, Graphite, and Logstash on high-performance KVM architecture.
Is your server actually slow, or is it just waiting on I/O? A deep dive into diagnosing Linux performance issues using vmstat, strace, and Nginx metrics, tailored for the Norwegian hosting landscape.
Is your database crawling despite plenty of RAM? We dissect the hidden IOPS bottleneck in shared SAN architectures and explain why local SSD storage via KVM is the only viable path for high-performance hosting in Norway.
RAID is not a backup. In this deep dive, we explore battle-tested strategies for automating server backups using rsync, MySQL dumps, and cron on Linux systems, tailored for Norwegian data compliance.
Stop relying on users to tell you the server is down. We detail a robust monitoring stack using Nagios Core and Munin on CentOS, tailored for Norwegian infrastructure requirements.
