Below you&#8217;ll find steps to help you diagnose your server and find potential solutions.&nbsp;<\/p>\n<p dir=\"ltr\"><\/p>\n<h4 dir=\"ltr\"><strong dir=\"ltr\">Analyze CPU Usage:<\/strong><\/h4>\n<p dir=\"ltr\">Begin by establishing clear expectations for what your processes should typically consume and what the demand should be based on the applications running on your system.&nbsp;<\/p>\n<p><\/p>\n<p>Once expectations are set,&nbsp;utilize&nbsp;the &#8220;top&#8221; command for a real-time overview of system performance. We recommend checking the below information to see what may be causing your performance issues:<\/p>\n<ul>\n<li>CPU Usage: Monitor if CPU usage exceeds expected levels and identify which processes are consuming excessive CPU.&nbsp;<\/li>\n<li>Memory Usage: Check if memory usage approaches or exceeds the capacity expected for your applications.&nbsp;<\/li>\n<li dir=\"ltr\">Process Statistics: Detect any processes that deviate from expected resource consumption or that are stuck in an uninterruptible sleep state (D state).&nbsp;<\/li>\n<\/ul>\n<p><\/p>\n<p dir=\"ltr\">More information on how to analyze your CPU usage on Linux is available <u><a href=\"https:\/\/linuxconfig.org\/how-to-check-and-monitor-cpu-utilization-on-linux\" rel=\"noopener noreferrer nofollow nofollow\" target=\"_blank\"><u>here<\/u><\/a><\/u>.<\/p>\n<p dir=\"ltr\"><\/p>\n<h4><strong>Analyze Memory Usage:&nbsp;<\/strong><\/h4>\n<p dir=\"ltr\">Next you need to check the memory usage on your server, below are few things worth checking in regards to your servers memory usage:<\/p>\n<ul>\n<li>Total vs. Free Memory: Assess the balance between used and free memory in relation to what is expected under normal conditions.&nbsp;<\/li>\n<li>Buffers\/Cache: Linux optimizes memory usage by utilizing free memory for buffers and caches. Ensure there&#8217;s always some free memory available, even when buffer\/cache usage is high.&nbsp;<\/li>\n<li>Swap Usage: Excessive swap usage can signal that RAM is insufficient, potentially leading to significant performance degradation.<\/li>\n<\/ul>\n<p><\/p>\n<h4><strong dir=\"ltr\">Monitor Disk I\/O (Input\/Output) with &ldquo;iotop&rdquo; and Process Details with &ldquo;htop&rdquo;:<\/strong><\/h4>\n<p dir=\"ltr\">With the tools &nbsp;&#8220;iotop&#8221; and &#8220;htop&#8221; you can monitor the usage of processes on your server.<\/p>\n<ul>\n<li>iotop: Focus on which processes are causing the most disk read\/write activity, checking if it aligns with expected disk usage.&nbsp;<\/li>\n<li dir=\"ltr\">htop: An enhanced version of top with a more intuitive interface, providing detailed views of processes, CPU cores, and memory usage.<\/li>\n<\/ul>\n<p><\/p>\n<h4 dir=\"ltr\"><strong>Utilize System Logs and Implement Proactive Monitoring:<\/strong><\/h4>\n<p dir=\"ltr\">You can review system logs in \/var\/log\/syslog and \/var\/log\/messages for any signs of errors, warnings, or anomalies that could indicate hardware issues or misconfigurations.<\/p>\n<p dir=\"ltr\"><\/p>\n<p>There is more information on interpreting these log files on the <u><a href=\"https:\/\/contabo.com\/blog\/analysing-log-files\/\" target=\"_blank\" rel=\"noopener\"><u>Contabo blog here<\/u><\/a><\/u>.<\/p>\n<p><\/p>\n<p dir=\"ltr\">Also deploying monitoring solutions like Nagios, Zabbix, or Prometheus can help you to continuously track system health and receive alerts before minor issues escalate.&nbsp;<\/p>\n<p><\/p>\n<h4><strong>Performance Tuning Based on Findings:&nbsp;<\/strong><\/h4>\n<p>Finally you can adjust your system based on your analysis:<\/p>\n<ul>\n<li>System Parameters: Modify sysctl settings like vm.swappiness and fs.file-max to optimize kernel behavior.&nbsp;<\/li>\n<li>Application Configurations: Tailor configurations based on specific operational requirements and best practices.&nbsp;<\/li>\n<li>Upgrades: Consider upgrading your VPS\/VDS or switching to one of our dedicated server offerings, if more system resources are needed.&nbsp;<\/li>\n<\/ul>\n<p><\/p>\n<p>To help you in future troubleshooting, we recommend maintaining a detailed log of all changes made and seeking help from experts within the community forums of your application for further assistance.&nbsp;<\/p>\n<\/p>\n<p><span class=\"ast-load-more active\"><a href=\"https:\/\/help.contabo.com\/en\/support\/solutions\/articles\/103000287787-i-m-having-performance-issues-with-my-linux-server-what-can-i-do-\" rel=\"nofollow\">Details&#8230;<\/a> <\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>I&#8217;m Having Performance Issues With My Linux Server, What Can I Do?
