Tuned comes with redhat igb variety of tuning profiles; sensible defaults for various common server roles. If you have poor network performance on an otherwise beefy system, and see that several cores redhat igb idle, check that your network card have enabled multiple scheduling queues, and that they are spread over all available cores.
For apache and nginx, see the Logging elapse time in apache and nginx post describing how redhat igb log the necessary numbers. The different default profiles are well documentedand ugb a good starting point for customising your own, if desired.
RedHat Performance Tuning
For performance tuning, getting more oomph out of your very expensive servers, see Red Redhat igb Enterprise Linux 7 Performance Tuning Guide. For more modern monitoring, ElasticsearchLogstash and Kibana ELK are popular for for log redhat igb and visualisation. If done prematurely, or without any measurements, rddhat tuning may, of course, have the opposite effect.
You should graph the usage, queue and response time on the resources it uses. Stig works with redhat igb at Redpill Linpro. Joining redhat igb more than 11 years ago, Stig redhat igb currently working on automating our IT operations through Puppet and working on our cluster storage, logging and monitoring systems.
Even in this day of automation, and analysis, The old Mk1 Eyeball is still surprisingly useful, and for that, you need graphs, and not a wall of numbers.
To push data into your ELK setup, use Topbeat for redhat igb usage metrics, Filebeat redhat igb real time log file analysis, and Packetbeat for analysing your network data on the wire. Let us know if you are interested in joining our team!
The most important thing is: They should provide starting points for further exploration. This often means resource graphs for disk and network IO.
Tools for performance tuning tuna Tuna allows you to control processor and scheduling affinity. For power management, getting your laptop through the workday even when you forgot your charger at home, see Red Hat Redhat igb Linux 7 Power Management Guide.
Ensure you know your baseline before you start changing things. Check redhat igb our techblog or read our whitepapers and how-to guides. Start collecting data redhat igb establish a baseline Enable tuned, and select a sensible default Look at graphs, did we make the right choice?
They contain a tuned. Use what you know, like, or want to lgb.
If you have it available, use historical resource monitoring, with graphs. We’re always on the lookout for people with experience redhat igb Linux and open redhta software.
But done systematically, performance tuning can be redhat igb of a science than an artform. Munin should redhat igb you a lot of graphs by default when you install it, and more plugins to graph things ivb available in the contrib repository.
With multiple sockets, you can move your favourite processes to one socket, and the network handling to another.
For a web server, this would be number of requests, response time per request, and also size per response. Graph the number of requests per rdehat, as well as the request-response latency.

Also, you can show the pretty graphs to your boss in case they drop in and ask what redhat igb are spending precious company time on. Look for changes redhat igb how the system behaves, and decide to either keep the changes, or roll back.
Stig has a wide range of interests, of which the most recent kgb statistic analysis and public speaking.
