In an earlier blog post,<\/a> we had discussed how server performance monitoring<\/a> is not just about monitoring CPU, memory, and disk resources anymore. There is more to server performance monitoring than just three resources or metrics. That blog post covered several key performance indicators (KPIs)<\/a> that IT teams must track to ensure that their servers are performing well. In this blog post, we focus on another KPI \u2013 server uptime.<\/p>\n

<\/span>What is Server Uptime?<\/span><\/h2>\n

Current uptime of a server is measured as the amount of time that the server has been up and running since the last time it rebooted. Uptime is expressed in years, months, days, hours, minutes, and seconds. Every time the server reboots, up time is reset to 0 (zero) and starts increasing as the server remains up and operational.<\/p>\n

\"Tracking<\/p>\n

Figure 1: Uptime reported for a Windows server in the “Performance” tab of Task Manager<\/div>\n

On Unix systems, up time is measured using the \u201cuptime\u201d command. On Windows, up time is reported on the Performance tab of the Task Manager. Check the \u201cCPU\u201d setting.<\/p>\n

Sometimes, uptime is indicated as a percentage. Uptime, as a percentage, is computed as the time that the server has been operational, divided by the total measurement period. For high reliability, up time should be close to 100%. A value below 100% indicates that the server has been rebooted during the measurement period.<\/p>\n

<\/span>Server Uptime Monitoring with eG Enterprise<\/span><\/h2>\n

eG Enterprise agents on servers track the uptime of the server. At preset regular intervals, the up time of the server over the measurement interval is captured. For example, the figure on the top right shows what eG Enterprise reports. It checks every 5 mins. If the server has rebooted in 5 mins, eG Enterprise\u2019s report will show that and if it has, it will also report the time it is up out of those 5 mins. The overall up time of the server is also reported.<\/p>\n

\"Monitoring<\/p>\n

Server reboots are detected and uptime of the server during that measurement period is indicated.<\/p>\n

\"Details<\/p>\n

This information is then used to report on the percentage of up time of any server, for any period.<\/p>\n

Uptime and availability are often used interchangeably but they are not the same:<\/p>\n
