This plugin collects metrics from psutil which gathers information on running processes and system utilization (CPU, memory, disks, network).
It's used in the Snap framework.
- golang 1.6+ (needed only for building)
Note: This plugin does not require Python rather it depends on the go library gopsutil.
All OSs currently supported by snap:
- Linux/amd64
- Darwin/amd64
You can get the pre-built binaries for your OS and architecture under the plugin's release page. For Snap, check here.
Fork https://github.com/intelsdi-x/snap-plugin-collector-psutil
Clone repo into $GOPATH/src/github.com/intelsdi-x/:
$ git clone https://github.com/<yourGithubID>/snap-plugin-collector-psutil.git
Build the plugin by running make within the cloned repo:
$ make
This builds the plugin in ./build/
- Set up the Snap framework
Some metrics are platform specific (see gopsutil's current status).
Available configuration option:
- mount_points - configuration of mount points to monitor, multiple paths should be separated with "|", e.g. "/|/dev|/run", default is set to collect only physical devices (hard disks, cd-rom, USB). Passing
*enables collect data from all mount points.
There are a number of other resources you can review to learn to use this plugin:
- gopsutil (go based implementation)
- psutil (python based implementation)
- Snap psutil integration test
- Snap psutil unit test
- Snap psutil examples
List of metrics collected by this plugin can be found in METRICS.md file.
This is an example running psutil and writing data to a file. It is assumed that you are using the latest Snap binary and plugins.
The example is run from a directory which includes snaptel, snapteld, along with the plugins and task file.
In one terminal window, open the Snap daemon (in this case with logging set to 1 and trust disabled):
$ snapteld -l 1 -t 0
In another terminal window: Load psutil plugin
$ snaptel plugin load snap-plugin-collector-psutil
See available metrics for your system
