How do you interpret load average?
If the 1 minute average is higher than the 5 or 15 minute averages, then load is increasing. If the 1 minute average is lower than the 5 or 15 minute averages, then load is decreasing. If they are higher than your CPU count, then you might have a performance problem (it depends).
How is server load measured?
The load is calculated over a specific time period and is often expressed as an average. The “load average” is usually expressed as three numbers—representing the load one minute earlier, five minutes earlier, and fifteen minutes earlier. The smaller the load average, the less strain is being put on your server.
What is the load of a server?
Load expresses how many processes are waiting in the queue to access the computer processor. This is calculated for a certain period of time, and the smaller the number the better. We consider a load value under 10 to be acceptable.
What is considered high load average?
A load average higher than 1 refers to 1 core/thread. So a rule of thumb is that an average load equal to your cores/threads is OK, more will most likely lead to queued processes and slow down things.
What is high server load?
High server load is an issue that can affect any website. Some symptoms of high server load include: slow performance, site errors, and sometimes even site down responses. Troubleshooting high server load requires SSH access to the server where your site resides.
Why is server load high?
The server load can be caused by the excessive usage of the system resources. Excessive usage of the CPU or Memory or Disk Space can lead to the server load.
What is a high server load?
What does the load average of a server mean?
In other words, it is the CPU demand of a server that includes sum of the running and the waiting threads. Typically, the top or the uptime command will provide the load average of your server with output that looks like: These numbers are the averages of the system load over a period of one, five, and 15 minutes.
What’s the load average for a single CPU?
To understand the load average number, you need to know how many CPUs your system has. A load average of 6.03 would indicate a system with a single CPU was massively overloaded, but it would be fine on a computer with 8 CPUs. The load average is especially useful on servers and embedded systems.
What do the load average numbers on Linux mean?
Linux, Mac, and other Unix-like systems display “load average” numbers. These numbers tell you how busy your system’s CPU, disk, and other resources are. They’re not self-explanatory at first, but it’s easy to become familiar with them.
Is there a way to monitor the load average?
Monitoring the load average consistently to maintain efficient management of the existing set up is an ideal alternative. Site24x7 Server Monitoring not only monitors the load average, but also provides complementary fault resolution tools to act before a high load average impacts server performance.
