Intel® System Health Inspector

System Health Inspector aka "svr-info" is a Linux command line tool used to assess the health of Intel® Xeon® processor-based servers.

Quick Start

wget -qO- https://github.com/intel/svr-info/releases/latest/download/svr-info.tgz | tar xvz
cd svr-info
./svr-info

Example

HTML Report

Options

Remote Target

Data can be collected from a single remote target by providing the login credentials of the target on the svr-info command line.

./svr-info -ip 10.100.222.123 -user fred -key ~/.ssh/id_rsa

Multiple Targets

Data can be collected from multiple remote targets by placing login credentials of the targets in a 'targets' file and then referencing that targets file on the svr-info command line. See the included targets.example file for the required file format.

./svr-info -targets <targets file>

Benchmarks

Micro-benchmarks can be executed by svr-info to assess the health of the target system(s). See the help (-h) for the complete list of available benchmarks. To run all benchmarks:

./svr-info -benchmark all

Notes:

• Benchmarks should not be run on live/production systems. Production workload performance may be impacted.
• Running all benchmarks, i.e., --benchmark all, will take 4+ minutes to run. The frequency benchmark execution time increases with core count (approx. (# of cores + 10)s). If not all benchmarks are required, use the --help option to see how to choose specific benchmarks, e.g., --benchmark cpu,disk.

System Profiling

Subsystems on live/production system(s) can be profiled by svr-info. See the help (-h) for the complete list of subsystems. To profile all subsystems:

./svr-info -profile all

Workload Analysis

Workloads on live/production system(s) can be analyzed by svr-info. One or more perf flamegraphs will be produced. See the help (-h) for options. To analyze system and Java apps:

./svr-info -analyze all

Report Types

By default svr-info produces HTML, JSON, and Microsoft Excel formatted reports. There is an optional txt report that includes the commands that were executed on the target to collect data and their output. See the help (-h) for report format options. To generate only HTML reports:

./svr-info -format html

Additional Data Collection Tools

Additional data collection tools can be used by svr-info by placing them in a directory named "extras". For example, Intel® Memory Latency Checker can be downloaded from here: MLC. Once downloaded, extract the Linux executable and place in the svr-info/extras directory.

We welcome bug reports, questions and feature requests. Please submit via Github Issues.

Building svr-info

Due to the large number of build dependencies required, a Docker container-based build environment is provided. Assuming your system has Docker installed (instructions not provided here), the following steps are required to build svr-info:

• builder/build creates the necessary docker images and runs make in the container After a successful build, you will find the build output in the dist folder.

Incremental Builds

After a complete build using the build container, you can perform incremental builds directly on your host assuming dependencies are installed there. This can make the code/build/test cycle much quicker than rebuilding everything using the Docker container.

If you are working on a single go-based app. You can run go build to build it.

Including Additional Collection Tools In The Build

Additional data collection tools can be built into the svr-info distribution by placing binaries in the bin directory before starting the build.
