Performance Co-Pilot PCP is an open source framework and toolkit for monitoring, analyzing, and responding to details of live and historical system performance. PCP has a fully distributed, plug-in based architecture making it particularly well suited to centralized analysis of complex environments and systems. This page provides quick instructions how to install and use PCP on a set of hosts of which one a monitor host will be used for monitoring and analyzing itself and other hosts collector hosts.
For other operating systems and distributions you might want to consider installation from sources. The default configuration includes over metrics with negligible overall overhead when queried.
If no queries for metrics are sent to the agent, it doesn't do anything at all. Local PCP archive logs will also be enabled on the host for convenience with pmlogger 1. Installing Monitor Host The following additional packages can be optionally installed on the monitoring host to extend the set of monitoring tools from the base pcp package.
Install various system monitoring tools, graphical analysis tools, and documentation: yum install pcp-doc pcp-gui pcp-system-tools or apt-get or dnf or zypper To enable centralized archive log collection on the monitoring host, its pmlogger is configured to fetch performance metrics from collector hosts. Enable recording of metrics from remote host acme. Note that a default configuration file config. This process is optional a custom configuration for each host can be provided instead , see the pmlogconf 1 manual page for details on this.
Dynamic Host Discovery In dynamic environments manually configuring every host is not feasible, perhaps even impossible. The following examples illustrate some of the most useful use cases, please see the corresponding manual pages for each command for additional information. Shell completion support for Bash and especially for Zsh allows completing available metrics, metricsets with pmrep , and available command line options.
Archives are self-contained, and machine- and version-independent so they can be transfered to any machine for offline analysis. The iostat2pcp 1 importer is in the pcp-import-iostat2pcp package and the sar2pcp 1 importer is in the pcp-import-sar2pcp package. Also for security reasons, only root can access some details of running processes of other users.
The metrics will be available under the namespace hotproc. This allows monitoring these processes regardless of their PIDs and also logging the metrics easily. Enable monitoring of all Java instances on the fly and display all the collected metrics: pmstore hotproc. It offers an extremely low overhead instrumentation facility that is well-suited to long running, mission critical applications where it is desirable to have performance metrics and availability information permanently enabled.
Java applications may use the separate Parfait class library for enabling MMV. See the Performance Co-Pilot Programmer's Guide for more information about application instrumentation. Performance Metrics Inference Performance Metrics Inference Engine pmie 1 can evaluate rules and generate alarms, run scripts, or automate system management tasks based on live or past performance metrics.
Enable monitoring of metrics from remote host acme. To enable and start PMIE: systemctl enable pmlogger pmproxy redis systemctl start pmlogger pmproxy redis Redis can be run standalone or in large, highly available setups. It is also provided as a scalable service by many cloud vendors.
The metrics indexing process is designed to spread data across multiple Redis nodes for improved query performance, so adding more nodes can significantly improve performance. Examples of the pmseries query language can be found on the man page. These queries can be executed from the command line utility, or from the grafana-pcp plugin for Grafana see the PCP Web Services section below. Custom applications can access all the available PCP information using this method, including custom metrics generated by custom PMDAs.
Derived Metrics PCP provides a wide range of performance metrics but still in some cases the readily available metrics may not exactly provide what is needed.
Derived metrics see pmLoadDerivedConfig 3 may be used to extend the available metrics with new derived metrics by using simple arithmetic expressions see pmRegisterDerived 3. The pcp-libs-devel package contains all the needed development related examples, headers, and libraries. Slightly more complex examples are the pcp-free, pcp-mpstat, pcp-numastat commands. To install basic PCP tools and services and enable collecting performance data on systemd based distributions, run: yum install pcp or apt-get or dnf or zypper systemctl enable pmcd systemctl start pmcd systemctl enable pmlogger systemctl start pmlogger.
Install various system monitoring tools, graphical analysis tools, and documentation: yum install pcp-doc pcp-gui pcp-system-tools or apt-get or dnf or zypper.
To install pmfind to begin monitoring discovered metric sources, run: systemctl enable pmfind systemctl restart pmfind. Monitor performance metrics with a GUI application with two second default interval from two different hosts.
Replay vmstat like metrics using a customizable metricset definition from the pmrep. To enable and start PMIE: systemctl enable pmie systemctl start pmie. To enable and start PMIE: systemctl enable pmlogger pmproxy redis systemctl start pmlogger pmproxy redis.

Sometimes people are looking for sysctl cargo cult values that bring high throughput and low latency with no trade-off and that works on every occasion. That's not realistic, although we can say that the newer kernel versions are very well tuned by default.

After being a Linux Administrator for 5 years in IT industry , I came to know that how hard is to monitor and keep systems up and running. These commands are available under all flavors of Linux and can be useful to monitor and find the actual causes of performance problem. This list of commands shown here are very enough for you to pick the one that is suitable for your monitoring scenario. The top command used to dipslay all the running and active real-time processes in ordered list and updates it regularly. It also shows high memory and cpu utilization of a running processess.
