How do you find the server load average?

How do you find the server load average?

Check the load on your server using the uptime command. The example shows the output from uptime . When the command ran at 15:16:45, the server had been up for 41 days 2 hours and 35 minutes , there were two users logged on, and the load averages were 0.01 , 3.01 , and 2.70 .

What is acceptable load average?

The general rule of thumb is that the load average shouldn’t exceed the number of processors in the machine. If the number of processors is four, the load should generally stay under 4.0.

How do I monitor Apache Web server load and page statistics?

How to Enable mod_status in Apache

1. Configure mod_status. Now again search for the word “Location” or scroll down until you find a section for mod_status which should look like following.
2. Enable ExtendedStatus.
3. Restart Apache.
4. Access mod_status Page.
5. Command-line Status Page View.

How do you read load average?

The numbers are read from left to right, and the output above means that:

1. load average over the last 1 minute is 1.98.
2. load average over the last 5 minutes is 2.15.
3. load average over the last 15 minutes is 2.21.

What is ideal load average in Linux?

Optimal Load average equals your number of CPU Cores. if you have 8 CPU Cores (can be found using cat /proc/cpuinfo) on a Linux server, the ideal Load average should be around 8 (+/- 1). If its > 8, then the server resources are over-utilized and if < 8, the server isn’t running with its full potential.

How do I get Apache metrics?

Apache web server exposes metrics through its status module, mod_status….Once you enable ExtendedStatus, you will see these additional metrics on the mod_status page:

1. total accesses/hits.
2. total kBytes served.
3. CPU load.
4. uptime.
5. requests per sec.
6. bytes per sec.
7. bytes per request.

How do I monitor my Apache server?

Monitoring Apache with native tools Apache has a module called mod_status that provides a fairly in-depth look at what Apache is doing at any given time, including a summary of performance data like current CPU usage and the total number of requests made since the Apache HTTPD Server was started.

What is the normal load average in Linux?

On Unix-like systems, including Linux, the system load is a measurement of the computational work the system is performing. This measurement is displayed as a number. A completely idle computer has a load average of 0. Each running process either using or waiting for CPU resources adds 1 to the load average.

What is the difference between load average and CPU utilization?

Basically, load average is the amount of traffic to your CPU(s) over the past 1, 5, and 15 minutes. Generally you want this number to be below the number of CPU(s)/cores you have. 1.0 on a single core machine means it’s using the CPU to it’s maximum, and anything above that means things are getting queued.

What should be the load average in Linux?

For a dual-core processor, a load of 1 means that 1 core was 100% idle. This translates to approximately 50% CPU usage. Similarly, it would represent 25% CPU usage for a quad-core processor. Load Average in Linux takes into account the waiting threads and tasks along with processes being executed.

How is Web server performance measured?

If you’re having issues with an application performing slowly, these metrics are a good place to start.

1. Metric 1: Requests per second.
2. Metric 2: Data in and data out.
3. Metric 3: Average response time.
4. Metric 4: Peak response time.
5. Metric 5: Hardware utilization.
6. Metric 6: Thread count.
7. Metric 7: Uptime.

What is Apache scoreboard?

Apache keeps track of server activity in a structure known as the scoreboard . There is a slot in the scoreboard for each child server and its workers (be it threads or processes), containing information such as status, access count, bytes served and cpu time, and much more.

How can I make Apache faster?

Here are top 5 ways to speed up Apache web server.

1. Use Apache Latest Version. Every Apache version contains performance improvements that make it faster than previous versions.
2. Use Disk based caching.
3. Choose the right MPM module.
4. Use mod_gzip/mod_deflate modules.
5. Do Not set High KeepAliveTimeout.

How do I Analyse Apache logs?

Apache Access Logs Location

1. On Red Hat, CentOS, or Fedora Linux, the access logs can be found in the /var/log/httpd/access_log by default.
2. On Debian and Ubuntu, you can expect to find the Apache logs in the /var/log/apache2/access.log and.
3. FreeBSD will have the Apache server access logs stored in /var/log/httpd-access.
